Two Channel Digital Receiver
Rio Rancho, NM 5
Technical Description
The DSR digital 2-channel receiver is a much-requested,
versatile slot receiver, equally appropriate for bag use,
as well as camera hop applications. It has been specially
designed to be Unislot mount-compatible.
Compatibility Modes
The DSR receiver was designed to operate with Lec-
trosonics digital transmitters from the D2, DCH and M2
series. The receiver is also backward compatible with
Digital Hybrid Wireless® transmitters including those
with NA Hybrid, NU Hybrid, JA HYBRID and EU Hybrid
modes.
Encryption
The DSR receiver features AES 256-bit, CTR mode en-
cryption, with 4 dierent key policies available. For use
with D2, DCHX and HDM Compat modes.
RF Frequency Tracking Front-End
In addition to the extremely high IP3 capability of the
receiver, to signicantly reduce unwanted interference
and intermodulation problems, the DSR has a frequency
selective front-end section that tracks and tunes to the
desired signal frequency and rejects unwanted interfering
signals. The low noise, high current RF amplier was de-
signed with feedback regulation for stability and precise
gain in order to handle stronger RF signals without over-
load. This produces a robust front-end that is as selec-
tive as xed single frequency designs and is suitable for
use in close proximity to other receivers and transmitters
commonly used in eld production bag systems.
Smart Noise Reduction (SmartNR
™
)
The DSR has been meticulously designed using the best
available low noise components and techniques. None-
theless, the wide dynamic range of digital and Hybrid
transmission technology, combined with at response
to 20 kHz, makes it possible to hear the -120 dBV noise
oor in the transmitter’s mic preamp, or the (usually)
greater noise from the lav microphone itself. (To put this
in perspective, the noise generated by the recommended
4k bias resistor of many electret lavaliere mics is –119
dBV and the noise level of the microphone’s electronics
is much higher.) In order to reduce this noise and thus
increase the eective dynamic range of the system, the
DSR is equipped with a selectable Smart Noise Reduc-
tion algorithm, which removes hiss without sacricing
high frequency response.
The Smart Noise Reduction algorithm works by attenuat-
ing only those portions of the audio signal that t a statis-
tical prole for randomness or “electronic hiss.” Desired
high frequency signals having some coherence such as
speech sibilance and tones are not aected.
The Smart Noise Reduction algorithm has three modes
- OFF/NORMAL/FULL - selectable from a user setup
screen. When switched OFF (the default setting for
digital compat modes) no noise reduction is performed
and complete transparency is preserved. All signals
presented to the transmitter’s front end, including any
faint microphone hiss, will be faithfully reproduced at
the receiver. When switched to NORMAL, (the factory
default setting for Hybrid modes) enough noise reduc-
tion is applied to remove most of the hiss from the mic
preamp and some of the hiss from lavaliere microphones.
The noise reduction benet is dramatic in this position,
yet the degree of transparency maintained is exceptional.
When switched to FULL, enough noise reduction is ap-
plied to remove most of the hiss from nearly any signal
source of reasonable quality, assuming levels are set
properly at the transmitter. This additional noise reduc-
tion comes at the cost of some transparency for low-
level room noise, yet the algorithm remains undetectable
under most circumstances.
Audio Output Level
A setup screen is provided for adjusting the audio output
level in 1 dB increments from -50 to +7 dBu using the
front panel MENU/SEL, UP, and DOWN buttons.
Test Tone
To assist in matching the audio levels of equipment con-
nected to the DSR, a 1 kHz audio test tone, adjustable
from -50 to +7 dBu in 1 dB increments, is available at the
outputs. If using AES3 outputs, the level is xed and can-
not be adjusted.
Power Supply
The DSR is operated from an external DC power source.
The receiver has a built-in Poly-Fuse for protection.
This fuse automatically resets if the power supply is
disconnected for about 15 sec. The power section also
has protection circuits that prevent damage to the receiver
if a positive ground power source is applied.
Color LCD Display
The display has four primary “home” windows. Pressing
the Front Panel PWR/BACK button steps through each
of these windows. After power is turned o and back on
again, the unit defaults to the Main window and to the
most recent frequencies, audio levels, transmitter battery
conditions, and other user settings. The display illumina-
tion can be set to time out in 5 seconds, 30 seconds, or
never.
Power O
When the Front Panel Power/Back button is pressed
for several seconds, the audio output is instantly muted
(squelched) and the message “POWERING OFF...” is
displayed briey before the receiver switches o.

RF Setup
Finding Clear Frequencies with SmartTune:
SmartTune is the easiest and fastest way to scan the
local RF spectrum and nd clear operating frequencies.
The receiver will scan through the selected tuning band-
width and automatically nd “empty” areas within the
tuning range that have little or no RF energy. The receiver
will then be set to a frequency within an empty area and
prompt you to continue or use the IR function to sync to
a transmitter.
Note: Pressing BACK during an active scan will
restore the operating frequency to what it was
set at pre-scan.
Transmit frequency range is compatibility mode depen-
dent (see Compat Mode for further details). Tune Re-
ceiver 1 is the rst screen you will see when you enter
SmartTune. After selecting either Tune Rx1 or 2, using the
UP/DOWN buttons, press MENU/SEL to open the TX
Range? page, then use the UP/DOWN buttons to select
the frequency range of the transmitter.
After choosing the band, the unit will scan the available
spectrum and choose the frequency with the lowest in-
terference and will display it as shown. If there is already
a frequecy programmed, you will have the choice to
choose the Old (Existing Frequency) or New Frequency.
Press the UP/DOWN buttons to toggle between the
choices, and press MENU/SEL to choose.
The chosen frequency will appear, with a “GO!” icon in
the lower right corner of the screen.
Face the transmitter’s IR port within a few inches of the
receiver’s IR port and press the DOWN button to begin
the sync. In digital compat modes, if the sync is suc-
cessful, the message “Sync OK” will appear on screen.
If unsuccessful, the message will show “IR Sync Failed”.
For Hybrid compat modes, “GO!” at the lower right will
blink, but the sync status will only show on the transmit-
ter’s display.
After the sync of Channel 1, choose MENU/SEL and the
screen will ask Do RX 2 Next? Use the UP/DOWN but-
tons to toggle between Yes and No; use MENU/SEL to
conrm. The screen will ask if you have Transmitter 1 on.
This ensures that the transmitters are tuned in a way that
they don’t interfere with each other.
It will then ask for TX2 Range? After you choose your
range, choose MENU/SEL and the DSR will search for
a clear frequency. It will ask to sync. Press the DOWN
button to sync the transmitter to the receiver. When com-
plete, press PWR/BACK to return to the MAIN SCREEN.
Frequency:
Allows manual selection or group tuning of the operating
frequency for each channel. The frequency setup screen
has dierent elds depending on mode selected. In digi-
tal modes, with no tuning group selected, the frequency
setup page has four elds: receiver name, MHz, kHz, and
group selector. In Hybrid modes, with no tuning group
selected, the page has six elds: receiver name, block
selector, legacy hex code, MHz, kHz, and group selector.
The block selector can be used for block disambiguation
for any frequencies that overlap between blocks 470 and
19, or between blocks 23-24 and 606.

Digital Mode Hybrid Mode
To manually tune: start by selecting Channel 1 or 2 in
the upper right corner. Then, press MENU/SEL to select
the desired eld to edit, using the UP or DOWN buttons.
MHz value can be changed in increments of 1 MHz by
pressing the UP or DOWN buttons. To keep the selected
value, press the MENU/SEL button. The kHz value can
be changed in increments of 25 kHz by pressing the
UP or DOWN buttons. Pressing MENU/SEL and UP
or DOWN at the same time tunes in larger steps. In the
MHZ eld, in 10 MHz steps; in the kHz eld, in 100 kHz
steps.
Tuning Groups:
Tuning groups are an important feature within the RF Set-
up menu that allow the user to create, store, share, recall,
and use lists of frequencies with associated names and
compat modes, quickly and easily. Four tuning groups
are available, each containing 32 frequencies. See Group
Edit for how to set up and edit these tuning groups.
When a tuning group is assigned on the Frequency page,
the tunable frequencies are limited to those contained in
the group. Press MENU/SEL to move the cursor among
the available options, and UP and DOWN buttons to
change values.
First, select receiver 1 or 2. Move the cursor again to the
group setting. Use the UP or DOWN buttons to select
among the four groups u, v, w, or x. Press MENU/SEL
again to move the cursor to the Name selector. Use
the UP or DOWN buttons to scroll among the available
names in the group, in alphabetical order, and the as-
sociated group frequency will change to match. Press
MENU/SEL to move the cursor to the Freq selector. Use
the UP or DOWN arrows to scroll the available frequen-
cies in the group in numerical order.
NOTE: If the frequency is blinking, it means
that the currently tuned frequency is not in the
selected group. If it is steady, it means that the
currently tuned frequency is in the selected
group. Choose No Group to exit the group tuning
mode and thus have access to any frequencies
within the tuning range of the receiver.
To add or remove frequencies from a tuning group, see
Group Edit.
Scan:
Scans for an open frequency and shows a graphic
representation of RF energy in the area, by frequency.
Navigating to the Scan page immediately begins the
scan. You can pause the scan by holding down MENU/
SEL; you’ll see the indicator in the center change to “o.”
Pressing MENU/SEL again resumes the scan.
Scan Zoom:
To zoom the screen, rst pause the screen. Press the
UP+DOWN buttons together to zoom (a small magnify-
ing glass will appear in the right corner). Press the UP
or DOWN arrows to navigate within the zoomed results.
Pressing MENU/SEL clears changes. To exit the zoomed
view, press UP+DOWN again to return to the previous
screen.
Clear Scan Data:
Clears scan results. Highlight CLEAR SCAN in the menu,
then press MENU/SEL. The screen will quickly show
Scan Data Cleared.
Group Edit:
Allows the user to add, edit, or delete entries within the
available tuning groups. Use the UP or DOWN arrow but-
tons to highlight which group to edit, then press MENU/
SEL. If the selected group is empty, “New Entry…” will
be highlighted. Press MENU/SEL to create a new entry.
Use MENU/SEL to move the cursor among the editable
elds. For MHz and kHz, use the UP or DOWN buttons
to select the desired numerical values.
With the Name eld highlighted, use the UP or DOWN
buttons to choose the desired letters or numbers, and
the MENU/SEL button to move the cursor to the next
slot in the name eld. Up to 8 characters are available.
When the name is complete, press the BACK button.
Then, press MENU/SEL to move the cursor to the Com-
pat Mode selection. Use the UP or DOWN buttons to
select the desired compat mode for this entry.
Press MENU/SEL and “GO!” will appear at the lower
right corner of the display. Press the DOWN button to
save the entry.
NOTE: For any frequencies
in a block overlap area
(blocks 470/19, 23/606/24)
and a Hybrid mode is
selected, it is important to
also define which block
is desired for proper
operation, otherwise there
may be a pilot tone conflict.

Editing Existing Entries:
Editing group entries is done the same way they were
created, with the exception of the “Del” (delete) box. To
delete an entry, press MENU/SEL to navigate to the de-
lete box, then use the UP or DOWN buttons to select or
unselect, press MENU/SEL and “GO!” will appear at the
bottom right. Press the DOWN button to complete.
Diversity:
Choose between: Vector or Frequency. Diversity modes
safeguard against loss of audio signal caused by Mul-
tipath. If you choose Frequency, the system will ask you
to calibrate. The calibration step is necessary for match-
ing audio levels between channels for seamless results.
Using Diversity Modes
Two diversity reception modes are available:
• Vector Diversity uses two receiver front ends per
audio channel, yielding two total channels.
• Frequency Diversity uses both receiver channels
and two transmitters per audio channel. The sec-
ond receiver will automatically be set to the same
Compat Mode as CH1 when this diversity mode is
selected.
Vector Diversity
Vector Diversity works by expressing the signal from
each antenna in angle and magnitude (vector). This
makes it possible to continuously rotate one of the vec-
tors mathematically so the angles match and the sig-
nals can be combined constructively. In this way, all the
energy that is available at both antennas is always fully
contributing to the receiver’s performance.
Frequency Diversity
Frequency Diversity diers from vector diversity in that it
uses both receiver channels and two transmitters operat-
ing on dierent frequencies. The purpose of this mode is
to have redundancy in the system for critical productions,
such as live television, to guard against failures caused
by dead batteries and multipath dropouts.
Frequency Diversity requires that the levels of the two au-
dio channels to be closely matched to avoid audible level
changes as the blending action takes place. In order for
this blending to work properly, a special test mode helps
to get the transmitter levels exactly matched.
Note: In Frequency Diversity mode, both
transmitters must be the same type (usually the
same model). The microphones must also be
placed very close together to minimize comb
filtering.
The DSR allows null
testing with a special
calibration mode as
shown on the display.
When the display shows
“calibrate,” it should be
possible to achieve a null.
Calibration is automatically activated on selection of the
Frequency Diversity mode, and automatically cancelled
on exiting the diversity setup page. Calibration can be
toggled on and o for testing but will revert to Operate
mode on exiting the diversity setup page.
To prepare for operation in the Frequency Diversity
mode, make the following adjustments:
1.Set up the transmitters according to their in-
structions. Verify that both transmitters are set to
the same audio polarity, and set to the same input
gain level. Turn them on to transmit, and verify that
audio and RF signals are present at the receiver.
Place the two microphone elements as closely to-
gether as possible, and place them where there is
a steady source of sound. Pink noise from a loud-
speaker, headphone, or smartphone is ideal. Make
sure it is loud enough to modulate the receiver
audio to the middle of the range on both channels.
2. Connect a headphone amplier to one of the audio
outputs on the DSR (in Frequency Diversity mode,
the resulting blended audio is mirrored on both
outputs). In the photograph, an MTCR is used.
Plug a set of headphones into the amplier jack to
monitor the blended output.
3. In the “Calibrate” mode, the two receiver channels
are placed out of polarity from each other. While
listening to the blended output, adjust the gain
control on one of the transmitters so that the audio
level drops signicantly (nulls) as the two channels
cancel each other. For the best performance in Fre-
quency Diversity mode, adjust the mic gain up and
down on one transmitter as described, listening for
the deepest null.
4. Once completed, Press the PWR/BACK button to exit
this screen, which will automatically change from from
“Calibrate” to “Operate”. While still on the Diversity se-
lection page, you can select “Calibrate” with the MENU/
SEL button, then change to “Operate” by pressing the
UP or DOWN buttons.

Pilot Bypass:
Allows the user to bypass the pilot tone on each channel
while in a Hybrid compat mode and defeats the pilot tone
squelch when on (no pilot tone is required). “O” means
that pilot tone must be present to allow audio output.
This setting is compatibility mode dependent. If this op-
tion is not available for the mode you have chosen, the
screen will show N/A.
WARNING: Without a carrier present (a
transmitter on), the audio will be unsquelched
noise.
TxInfo:
Displays the Block and Step of the transmitter sync’d to
each channel.
Audio Setup
Audio Level:
Allows user to set Audio Output Level and Tone per
channel. These settings are Output Type dependent. If
AES is chosen, there are no adjustments available.
Pressing MENU + UP when channel is highlighted will
allow user to enable (or stop) 1kHz audio tone for level
setting.
Output Type:
Allows user to choose output for each channel, analog or
AES3.
Routing:
Allows user to choose to send audio of Channel 1 or 2
as analog or digital to Output 1 or to Output 2 as analog
only. The screens will look dierent depending on the
Output Type that is chosen. M> refers to a Mono feed.
Smart NR:
Allows user to enable Smart Noise Reduction on either-
receiver channel or both. Settings are: O, Normal and
Full. The default setting for digital compatibility modes is
“O.” The default setting for hybrid modes is “Normal.”
Talkback:
Allows user to enable the Talkback (TB) function on either
receiver channels or both, to determine where the TB
outputs are routed, and to select how the TB signals in-
teract with the normal program audio on those outputs. If
“O” is selected for a receiver channel, then no Talkback
function will occur on that channel, even if the transmit-
ter’s programmable switch is set to “TB” and activated.
“Override” indicates that if a TB command comes from
the transmitter, then the TB audio goes to the specied
receiver output, and the normal audio from that channel
is muted. “Mix” indicates that the TB audio and the stan-
dard audio routed to that receiver output will be mixed
to that output. “TB Only” indicates that the normal audio
routed to that output is muted, and only the TB audio will
be present, and, only when the TB command is activated
on the transmitter.
If AES3 output type is selected on Output 1, it is possible
to keep the normal audio on both channels separate from
any TB audio. Output 2, as mentioned, is mono and can-
not be changed.
Polarity:
Allows user to set audio polarity of each channel as
either positive or negative.
Compat Modes
Allows user to set compatibility mode per receiver chan-
nel. Available modes are: mono digital modes D2 and
HDM (High Density Mode); stereo digital modes Duet
channels 1-2, and DCHX (encrypted) channels 1-2; and
mono Hybrid modes: NA Hybrid, NU Hybrid, EU Hybrid,
and JA Hybrid. EU and JA modes are not available for
Block 941.
IR & Keys Menu
The operations below depend on the compatibility mode
selected and the transmitter used. The DSR has two-
way IR for use with digital products (DBu, DBSM, etc.)
and one-way IR for use with older IR-capable units such
as LT and HMa. One-way protocol can only “Send Fre-
quency.”
NOTE: You must position the transmitter’s IR
port directly in front of the DSR IR port, as
closely as possible, to guarantee a successful

Send Frequency
Sends operating frequency to the transmitter, each chan-
nel separately. Press the UP button to send the Channel
1 frequency, and the DOWN button to send the Chan-
nel 2 frequency. Success for digital compat modes is
indicated on the receiver as “IR Sync OK.” For digital
modes, failure will be indicated on the receiver as “IR
SYNC FAILED.” For Hybrid compat modes, success will
be indicated on the transmitter as “IR SYNC.” Failure
will be indicated on the transmitter as “CP Err” or “Block
Mismatch” depending on the transmitter model and the
source of the error.
Send All
(available only for digital compat modes)
Sends frequency, channel name/s, and Talkback state to
the transmitter. Press the UP button to send the informa-
tion from Channel 1, and the DOWN button to send the
information from Channel 2. Since two-way IR Sync is
only available for digital transmitters, “N/A” will be next
to any channels that are in a Hybrid compatibility mode.

(available only for digital compat modes)
Retrieve (get) transmitter’s frequency, Talkback state, and
channel name. Press the UP button to get all and use for
Channel 1. Press the DOWN button to get all and use for
Channel 2. Since two-way IR Sync is only available for
digital transmitters, “N/A” will be next to any channels
that are in a Hybrid compatibility mode.
Group Sync
These functions allows you to send or get Tuning groups
via IR sync to/from transmitters and receivers capable
of using Groups (DSR , DCHR, DBSM, DBSMD, DPR,
DPR-A). Use MENU/SEL button to navigate between
the group choice and the send/get mode. With the group
letter(s) highlighted, use the UP or DOWN buttons to
select which frequency group (or all groups) to send or
get. Then press the MENU/SEL button to select Send
or Get. Use the UP or DOWN buttons to toggle between
Send or Get. Then, press MENU/SEL again and “Go” will
appear in the lower right corner. Press the DOWN button
to complete the sync operation.
Encryption Key Management
The DSR has four options for encryption keys:
• Universal: This is the most convenient and basic
option available, and the default setting on all Lec-
trosonics D2 digital units. All encryption-capable
Lectrosonics transmitters and receivers contain
the Universal key. The key does not have to be
generated in the DSR. Simply set the Lectrosonics
encryption-capable transmitters and receivers to
Universal key type, and the encryption is in place.
This allows for convenient encryption amongst
multiple transmitters and receivers, but is not as
secure as creating a unique key.
• Shared: This key policy is designed for sports cov-
erage and similar applications where a unique key
provides enhanced security, but multiple transmit-
ters and receivers can share the same key. Once
generated by the receiver, the key can be trans-
ferred via IR to transmitters or additional receivers.
• Standard: This key policy provides excellent se-
curity, second only to the Volatile key policy. Once
a unique key is created in the receiver, it can be
transferred via IR only to transmitters, but not to
other receivers. The receiver tracks the number of
times the key is transferred. Once a Standard key
has been transferred 256 times, an alert will indi-
cate that a new key must be created.
• Volatile This is the most robust key policy avail-
able. After a unique key is created, it can be
transferred only to transmitters, not other receivers.
If a transmitter is powered o, it must have the key
sent to it again from the receiver. If the receiver is
powered o, a new key must be generated and
sent to the transmitters. In encryption terms, this is
the “one time use” key management policy.
Encryption Keys
The DSR generates high entropy encryption keys to sync
with encryption-capable transmitters. The user must
select a key type and create a key in the DSR, and then
sync the key with the transmitter.
1. Begin by selecting a Key Type.
IR&Keys --> Key Type --> Universal, Shared, Stan-
dard or Volatile.
2. Next, if using the Shared, Standard or Volatile key
type, select MAKE KEY to generate a new key.
Select “Yes” to conrm Make Key. IR&Keys -->
Make Key.
NOTE: When Universal Key type is selected,
there is no prompt to create key, as it is not
necessary.
3. A message will indicate that an Encryption Key has
been created.
4. Sync new key with transmitter (see Send Key). The
transmitted audio will then be encrypted with the
new key.
Send Key
Select SEND KEY to transfer the encryption key to
any compatible transmitters or, in Shared key policy,
additional receivers. Success will be indicated by the

Two Channel Digital Receiver
Rio Rancho, NM 13
message “Encryption Key Sent” on the receiver display,
and “Encryption Key Received” on the transmitter
display. IR key transfer failure will be indicated by the
message “IR Sync Failed” on the receiver display.
Settings Menu
Lock/Unlock
The user can lock or unlock the receiver. In Locked con-
dition, the menus and settings can be browsed but not
changed. Attempting to change a setting or power o the
unit while in the locked condition causes the message
“Settings Locked” to appear on the screen. The Lock/
Unlock condition will persist through battery changes or
external power being removed.
Backlight
Controls the display backlight timeout interval, following-
the last button push. Choose from always on, 30 sec-
onds, or 5 seconds. The backlight will automatically
come on with low battery warnings.
Rx On/O
Turns the power to each channel on or o. Use MENU/
SEL to set and move the cursor and the UP and DOWN
buttons to change values, then MENU/SEL to save and
move to the next channel.
TxBat Type
Set the battery type for each transmitter channel. Note
that for digital transmitters, the battery type is set in the
transmitter and thus if the transmitter is not on, “no link”
will show on that receiver channel. Use MENU/SEL to
toggle between Channel 1 and Channel 2, and then use
the UP and DOWN buttons to change the battery type
settings for those channels (depending on compat mode)
TxBatt Timer
Set transmitter battery timer alerts for each channel.
Choose to enable/disable alert, set time in hour and min-
utes and reset timer. Use MENU/SEL to set and move
the cursor and the UP and DOWN buttons to change
values. To re-set the timer for the selected channel, press
the MENU/SEL and UP buttons together.
TxBatt Icon
Choose between Bar, Volt or Time. Use MENU/SEL to
select the channel and the UP and DOWN buttons to

Press the UP or DOWN buttons to enable or disable the
auto power on function.
Edit Names
Allows the user to change the names of the Receiver
Channels 1 and 2, to display the names and to change
the name of the device itself (from the default “DSR” to,
say, a talent name).Use MENU/SEL to select the channel
and the UP and DOWN buttons to change values.
Locale
The locale should be chosen based on the region where
the receiver is being used, relative to the band the unit
was designed to operate within. The following options
are available:
- NA: (default setting) represents the North Ameri-
can locale and prevents operation in the
Astronomical Band (from 608 to 614 MHz). It allows
tuning from 470.100 up to 607.950 MHz on A1B1 and
from 537.600 to 607.950 MHz and 614.400 to
691.175 MHz on B1C1.
- EU: represents the European locale, and tunes at
470.100 up to 614.375 MHz on A1B1 and from 537.600
to 691.175 MHz on B1C1.
- AU: represents the Australian locale, and tunes to
520.000 to 614.375 MHz on A1B1, and from 537.600
to 691.175 MHz on B1C1.
Default
This setting restores the unit to factory settings.

Antenna Mounting and
Orientation
A variety of accessories are available to enable various
mounting options. For maximum operating range, the
antennas should be vertical and above the camera and
other equipment. The AMJ Rev. A antenna is jointed so
the whips can be oriented vertically.
Mount the receiver
so that the antennas
extend into clear air and
are oriented vertically
to provide a circular,
horizontal coverage
pattern
Do not mount the receiver so the
antennas will be next to another piece of
equipment nor oriented horizontally
The receiver provides stand-
alone operation with the battery
sled adapter and mounting
sleeve. It can be mounted in
any position with Velcro, or in
horizontal and vertical positions
using the mounting foot, or
mounted directly onto a 1/4-20
threaded stud on a tripod.
The diagrams below depict typical orientations of trans-
mitter and receiver antennas in eld production and how
the RF signal transfer is aected. Maximum sensitivity is
perpendicular to the whip, so an ideal setup is shown in
Fig. 1 and Fig. 2 where the receiver is mounted in either
a vertical or horizontal position with the whips oriented
vertically.
Fig. 3 depicts the receiver and antenna whips oriented
horizontally, which places the null of the receiver antenna
pattern pointing toward the transmitter. The result, of
course, is a weak signal entering the receiver.
Fig. 4 depicts the worst setup where the nulls in both
receiver and transmitter patterns face one another.
The transmitter antenna whips can point upward as
shown in these diagrams, but they will work just as well
with the whip pointing downward. Mount the transmit-
ter so that the whip is vertical and not in direct contact
with the wearer’s body or metallic objects in clothing and
costuming.

A “bendable” mounting strap is included that allows
vertical orientation on a variety of surfaces. Several other
adapters are also available for temporary or xed instal-
lations.
This is one example of using two splitters to feed two
receivers.
AMJ Jointed Antenna
The AMJ antenna is a general purpose design with a
hinged joint that pivots in both directions for positioning
the whip at any desired angle. The pivot allows the whips
to be oriented vertically regardless of the mounting posi-
tion of the receiver.
The hinged joint pivots in both directions
SNA600A Omni Dipole Antenna
The SNA600a antenna is a versatile tool for
use with wireless microphone receivers or IFB
transmitters. The center frequency of its 100
MHz bandwidth is tunable from 550 to 800 MHz;
however, the roll-o above and below this band
is gradual. The SNA600a measures lower than a
2:1 SWR (Standing Wave Ratio) from 465 MHz
to 850 MHz when the antenna arms are fully
extended.

Antenna/Block Reference Table
The two AMJ whip antennas supplied with the receiver are factory cut to specic frequency blocks as shown in the
table below. A colored cap and label are used on blocks 20 through 26, and a black cap and label are used on the
other blocks to denote the frequency range of each model.
The chart is useful for fabricating an antenna from coaxial cable or other materials, or for identifying the frequency of
an antenna that is not marked. The lengths shown are specically for the AMJ whip antenna with a SMA connector, as
determined by measurements with a network analyzer. The optimal length of the element in other designs will likely be
dierent than those shown in this table, but since the bandwidth is typically wider than the specied block, the exact
length is not critical for useful performance in whip, dipole and coaxial designs.

3. Turn each transmitter on one at a time.
Start with all transmitters turned o. As you turn on
each one, look at the matching receiver to verify a
strong RF signal is received. Then, look at the other
receivers and see if one of them is also picking up
the signal. Only the matching receiver should indi-
cate a signal. Change frequencies on either system
slightly until all channels pass this test, then check
again to see that all channels are still clear as done
in step 2.
4. Turn each transmitter o one at a time.
With all transmitters and receivers turned on, turn
each transmitter o one at a time, in turn, and look
at the RF level indicator on the matching receiver
module. The RF level should disappear or drop to
a very low level. If it does not, change frequency on
that receiver and transmitter and try it again. When
a clear frequency is found, turn the transmitter on
and move on to the next channel.
IMPORTANT: Any time a frequency is changed
on any of the systems in use, you must start at
the beginning and go through this procedure
again for all systems. With a little practice, you
will be able to do this quickly and save yourself
some “multi-channel grief.”
Interference can result from a wide variety of sources
including TV station signals, other wireless equipment in
use nearby, or from intermodulation within a multi-chan-
nel wireless system itself. Regardless of how the fre-
quencies were coordinated, a nal checkout procedure is
always a good idea.
Scanning with the RF spectrum analyzer built into the
DSR system will identify external RF signals, but it does
not address the compatibility of the selected frequencies.
The pre-coordinated frequencies address in-system in-
termodulation, but obviously cannot take into account RF
signals from external sources that may be present in the
location where the system will be operating.
1. Set up the system for testing.
Place antennas in the position in which they will be
used and connect to the receivers. Place trans-
mitters about 3 to 5 feet apart, about 25 to 30
feet from the receiver antennas. If possible, have
all other equipment on the set, stage or location
turned on as well, especially any mixing or record-
ing equipment that will be used with the wireless
system.
2. Set all receivers on clear channels.
Turn on all receivers, but leave the transmitters
o. Observe at the RF signal strength indicator for
each receiver module. If a signal is present, change
the frequency to a clear channel where no signal
is indicated. If a completely clear channel cannot
be found, select the frequency with the lowest RF
level indication. Once all receiver modules are on
clear channels, go to step 3.
