Thank you for selecting the Azden 1200 Series for your portable/ENG
on-camera UHF wireless needs. We are confident that these compo-
nents will perform beyond your expectations. For over 40 yearsAzden
Corporation has been creating technologically advanced products. By
takingadvantageof thelatestinCAD designandSMTproductiontech-
niques, Azden’s engineers are able to produce products that exceed
the published specifications and perform well beyond the warranty pe-
riod.
The 1200 Series represents a breakthrough in on-camera, digital fre-
quency-selectable UHF receivers and transmitters. Its enhanced per-
formance assures you of the highest image rejection combined with
thefinestinaudio clarity.Thecrystal-controlled,PLL-synthesizedmixer/
localoscillatorprovidesforextremelyaccuratefrequencyselectionwhile
the twin-antenna true diversity dual front-end reduces multipath distor-
tion caused dropouts to near zero.
In the real world of ENG the ability to be able to select a ‘clear’ fre-
quency on the spot is vitally important. Going out into the field with a
single-frequency unit invites disaster since there is no way of knowing
what frequencies will be used by the other crews that are covering the
same story. Think of your 1200 Series units as your insurance policy -
your assurance of getting the story.
Designed by professionals - for professionals, the 1200 Series will pro-
vide you with years of worry-free, high-quality performance.

SETTINGTHETRANSMITTING FREQUENCY ONTHE1200XT
Before the 1200XT can be used, it and the associated receiver have to be
set to the same frequency. This can be accomplished on the 1200XT trans-
mitter by first setting the LCD display to one of two views - ‘Frequency’ or
‘Channel’. To do this, after installing fresh batteries, turn the 1200XT to the
ON position [k]. Next, using the tip of a ballpoint pen, an unbent paper
clip or something similar, press the MODE button [g] repeatedly until one
of the two screens below appears.
Using either the UP or DOWN button [h] the desired receiving frequency
or channel number can be set. Tapping the button steps the frequency or
channel number one at a time while pressing and holding the button in
moves through the frequencies or channel numbers rapidly. There are 188
different frequencies or channel numbers to chose from. Once the desired
frequency or channel has been determined be certain to set both the trans-
mitter and receiver to match.

RECEIVERSETUP/USE(1200URX/ABand1200URX/VM)
The 1200URX/AB is a specially developed model that integrates the Anton/
Bauer “Gold Mount” to power the receiver. The 1200URX/VM is a specially
developed model that integrates the IDX battery-mount to power the receiver.
All of the functions and controls on the two models is the same except for the
method of powering the receiver. The 1200URX/AB attaches between the
camera and Anton Bauer battery pack using the “Gold Mount” system while
the 1200URX/VM attaches between the camera and an IDX “V-Mount” bat-
tery pack.
A.Attachingantennas:
To attach the high-gain antennas to the receiver, fit the BNC connector
on the antenna to the receiver [c], press down and rotate clockwise.
To remove rotate the antenna’s BNC connector counterclockwise and
pull up.
B.Connectingan Output cable:
Itis necessarytoconnecttheoutputofthereceiver[e]tothecamera’s
‘MIC’ or ‘Line’ input by means of a properly wired cable (not supplied).
The connector on the receiver is wired with pin 1 as Ground, pin 2 as
Positive(+)andpin3asNegative(-). Set the OUTPUT Line/Micswitch
on the receiver [j] to the appropriate position, matching the input on
the camera that is used.
C.Settingthereceivingfrequency:
Before the receiver can be used, it and the associated transmitter
have to be set to the same frequency. This can be accomplished on
the receiver by first setting the LCD display to one of two views -
‘Frequency’ or ‘Channel’. To do this, after applying battery power, first
turnthereceivertotheONposition[i].Next,usingthetipofaballpoint
pen, an unbent paper clip or something similar, press the MODE but-
ton [k] repeatedly until one of the two screens on the next page
appears.
POWERINGTHE1200XTTRANSMITTER
The 1200XT uses two “AA”Alkaline batteries for power. The batteries
are placed in the compartment by removing the battery compartment
door and placing the batteries in the compartment as shown

RECEIVER SETUP/USE - 1200URX/AB or 1200URX/VM (continued)
Using either the UP or DOWN button [l] the desired receiving fre-
quency or channel number can be set (the included chart shows the
relationship). Tapping the button steps the frequency or channel num-
beroneatatimewhilepressingandholdingthebuttoninmovesthrough
the frequencies or channel numbers rapidly. There are 188 different
frequencies or channel numbers to chose from. Once the desired fre-
quency or channel has been determined be certain to set both the
transmitter and receiver to match.

D.Power
The POWER ON/OFF switch [i] turns the receiver On or OFF. To
conserve battery life, it is best to turn the receiver ON only when it is
actually being used.
E. Output
Select either LINE or MIC [j] depending on which input is being used
on the camera.
F. Monitor
This control [g] adjusts the output level (MIN to MAX) at the earphone
monitor jack [d]. This is a 3.5 mm mono jack.
G. LCD Display
This display [h] shows several pieces of information. As discussed
previously, the frequency or channel number is shown. Additionally,
as the deversity receiver chooses which antenna is receiving the best
signal, the ‘A’ or ‘B’ segment of the LCD display will illuminate.
Using either the UP or DOWN button [l] the desired receiving fre-
quency or channel number can be set. Tapping the button steps the
frequency or channel number one at a time while pressing and holding
the button moves through the frequencies or channel numbers rapidly.

USINGTHE1200BTTRANSMITTER’SCONTROLSAND DISPLAY
A.Power
The POWER ON/OFF switch [e] turns the 1200BT On or OFF.
B. Audio
Priortoturningthe1200BTON itisbesttosettheAUDIOswitch[g]to
ST.BY. When ready to transmit, switch to ON. The ST.BYposition acts
as a ‘mute’ that maintains the RF signal but turns off the audio.
C. MIC
This 4-pin Hirose connector [h] is the microphone input. Azden pro-
duces a number of lapel, head-worn and neck-worn microphones that
are specifically suited for the 1200BT. In addition, other externally pow-
ered (5VDC) electret condenser microphones can be used when they
are properly wired with the correct Hirose connector (pin 1 is for audio
+, pin 2 is not used, pin 3 is for bias voltage and pin 4 is ground). If you
are using the 1200BT as a wireless instrument transmitter the connec-
tions are somewhat different (pin 1 is not used, pin 2 is the audio +, pin
3 is for bias voltage and pin 4 is ground).
D. Input Level Adjustment
This screwdriver adjustment [♣] controls the input level of the micro-
phone. Counterclockwise rotation reduces the input gain while clock-
wise rotation increases the input gain.
E. Belt-Clip
The metal belt-clip [c] provides a convenient method of attaching the
transmitter to the user.

SETTINGTHE TRANSMITTINGFREQUENCYON THE1200BT
Before the 1200BT can be used, it and the associated receiver have
to be set to the same frequency. This can be accomplished on the
1200BT transmitter by first setting the LCD display to one of two views
- ‘Frequency’ or ‘Channel’. To do this, after installing fresh batteries,
turnthe1200BTtotheONposition[e].Next,usingthetipofaballpoint
pen, an unbent paper clip or something similar, press the MODE but-
ton [j] repeatedly until one of the two screens below appears. The Group selections at the bottom of the chart only apply to the 1200URX/Si

THE1200URX/Si
The 1200URX/Si receiver is specially designed to work with specific
Panasonic “Slot-In” or Ikegami “Uni-Slot” cameras. Once mounted in
the camera, the DB-25 connector on the bottom provides the receiver
with power directly from the camera’s power supply (battery) while
delivering audio directly to the camera’s audio input. Items A.[c],C.
and D [i] on pages 1 and 2 apply directly to the 1200URX/Si.
1200URX/Si Top panel display and operation
The MODE Switch [k]performs 1 of 5 functions.
Initial MODE display:
The initial MODE shows the receiving band shown as Group, Channel
and Frequency. If there is no action taken with the MODE switch for 4
secondsthedisplaywillreturn totheInitialDisplay.PressingtheMODE
switch for one second while showing the Initial Display will cause the
currently set frequency to be displayed.
Mode#1 (GR):
From the Initial Display, quickly pressing the MODE Switch once dis-
plays the Group Display. Pressing the UP or Down buttons will change
the Group Number. There are 7 Groups, 6 of which have the best
selection of frequency combinations when using multiple systems.
Group0allowsforchoosing any channel/frequency. ThelastsetGroup
is memorized when the receiver is turned off. The chart on page 3
shows the Group vs Frequency combinations.

1200URX/Si Top panel display and operation (continued)
As the RF signal from the transmitter gets stronger (or weaker) the
number of illuminated LCD segments in the display will change - with 3
segments being the maximum and best. Similarly, the AF (audio level)
segments will light from 1 to 3 segments as the audio gets stronger or
weaker. In this case the best level is achieved as the display shows
between 2 and 3 segments. If all 3 segments stay illuminated for a
continued period of time it is likely that you are over-driving the
receiver’s input and you should reduce the transmitting level by either
moving the microphone further away from the sound source or reduc-
ing the input gain on the transmitter.
RECEIVER SETUP/USE - 1200URX/AB or 1200URX/VM (continued) Mode#2 (CH):
To change the channel/frequency within the selected group, press the
MODE switch a 2nd time. “CH” will be displayed. Using either the UP
or DOWN button [l] the desired receiving channel/frequency
combination can be set (the chart on page 3 shows the relationship).
Tapping the button steps the channel/frequency number one at a time
while pressing and holding moves through the combinations rapidly.
There are 188 different channel/frequency combinations to chose from
(Group “0” allows you to select all of the combinations). Once the
desiredchannel/frequencyhasbeendeterminedsetboththetransmitter
andreceivertomatch.WhenthereceiveristurnedOFFthelastchannel/
frequency chosen is stored in memory.
Mode#3 (SQ):
To change the squelch level, press the mode switch for a third time.
SQ will show in the display. There are 3 settings to choose from:
on on = RF mute ON - Tone mute ON (default)
on off = RF mute ON - Tone mute OFF
off off = RF mute OFF - Tone mute OFF
You can cycle through these with the UP/DOWN buttons. The Squelch
returns to the default when the receiver is turned OFF.
Mode#4 (SQ Level):
There are four levels of Squelch to choose from:
0 = Default
3 = 3dB (RF) increase to the default
-6 = 6dB (RF) decrease to the default
-3 = 6dB (RF) decrease to the default
You can cycle through these with the UP/DOWN buttons.
See the discussion at the bottom of page 2 and the top of page 4 for
information concerning the other parts of the display.
