OPERATION
3. Operation
3.1. Intercom (4x) [HB-DC-DBROnly]
The Intercom units provide a means to interface between two channels of 2-wire party-line intercom
audio and two channels of 4-Wire analog line-level signals. The unit can perform auto-nulling for each
channel with the push of a button. In addition, each of the 4-Wire input and output channel levels are
monitored and displayed on front panel VU meters.
With the flip of a switch the unit can be a +28VDC party-line voltage power source while providing the
200-ohm intercom audio termination on both channels. If so desired, the party-line source and
termination can be removed by just flipping the switch back. The unit can also be configured to work
with either RTS party-line or Clear Com party-line equipment with the flip of a front panel control switch.
This switch adjusts the output gain between the party line circuitry and the 4-wire line level circuitry
depending on which type of units one is interfacing with.

Switch 1
The Intercom can supply party-line power by moving the WET/DRY switch to the up position. With this
function enabled, the unit will provide +28 VDC to pin 2 of the XLR connector of the party-line ports.
When enabled, the CH1 WET LED will turn green. When selecting the WET mode, verify that the WET
LED is green. If red, it means there is a short or overload on the party-line, or the wetting circuitry within
the unit is defective. If the Intercom unit is to be connected to a party-line intercom system with an
existing power source, then the internal power supply within the Intercom board should be turned off.
This is accomplished by flipping the WET/DRY switch to DRY (down). When in DRY mode, the CH1
WET LED will go out. Pin 2 of the XLR connector will no longer provide +28VDC to the rest of the party-
line.

14 | P a g e
OPERATION
Switch 2
Set to RTS or Clear-Com mode.
To be compatible with RTS units, push the GAIN L/GAIN H switch UP; to be compatible with Clear Com
units push switch DOWN.
This switch adjusts the gain needed to interface between the 4-wire to 2-wire signals and it also adjusts
the gain from the 2-wire to 4-wire signals. It increases the gain going from a Clear Com connected 2-
wire unit to the 4-wire side of the interface to compensate for the lower 2-wire operating voltages of the
Clear Com units as compared to RTS units. The RTS units operate at a higher voltage on the party-line
side and thus require less gain when translating from 2-wire to 4-wire signals. When the signal
originates from the 4-wire side and translates over to the 2-wire side the gains are opposite. Less gain
is applied to a 4-wire input as it translates to the 2-wire side of the interface with when a Clear Com unit
is present on the party-line connection as opposed to a RTS unit.
Switch 3
The Intercom can be set to the AUTOTERM mode by pushing the WET TERM/AUT TERM switch
down. When this selection is chosen, the unit will look at both party-line channels to see if they contain
the +28 VDC wetting voltage. For channel 1 the unit’s internal circuitry will remove the internal 200-ohm
terminating resistor if the unit is sourcing the +28 VDC or if it is externally wetted. For Ch2, it will
remove the 200-ohm only if the channel is externally wetted. (Ch2 cannot be internally wetted). If the
WET TERM is selected, then if the Intercom is providing the +28 VDC (WET/DRY switch set to WET),
both channels will be terminated. If the Intercom is not providing the +28 VDC (WET/DRY switch set to
DRY) then the terminations on both channels are removed.
NULL Toggle Switch (Ch1 & Ch2)
Auto nulling is done to achieve maximum return loss between the 4-wire input and the 4-wire output
channels. Auto nulling can be and should be done whenever there’s been changes made to the party-
line connections.
To auto null Channel 1, slide the NULL switch to the left momentarily and release. Observe that the null
CH1 status LED glows orange while the nulling process is taking place. The Intercom will also produce
a 24khz Mic Kill tone. RTS compatible belt packs will respond to this tone and automatically kill the mic
input. If you have another type of belt pack, be sure to turn off the mic input or the null will be poor. The
process should last about 20 seconds after which time the LED will turn green if successful or red if a
null was not able to be obtained. Wait for the auto nulling process to complete on one channel before
attempting to do it on the other channel. Repeat these steps for nulling Channel 2 by momentarily
sliding the switch to the right while observing the CH2 LED alongside it. During the auto nulling process
there will be tones of 1kHz, 300Hz, 3kHz and 1kHz again on each of the party line channels.
After the nulling process is complete, you will need to re-enable your mic inputs. If two or more
Intercom units are used as part of the 2-Wire system, they should be nulled to prevent an audio
feedback path that may cause an audio oscillation. This is evidenced by the VU LEDs being maxed, as
well as an audio squeal, howling or whistle. Once the units are nulled, this should go away. But it can
also return if one of the belt packs or other loads are changed or disconnected from one or both ends.
Then the oscillation will return since the load that the intercom has been nulled for is suddenly gone,

15 | P a g e
OPERATION
and the resulting lack audio return loss will result in feedback. Note that if the party line has been
altered after a null has been done, the status LEDs will not update on their own. They do not monitor
status on a continuous basis. They only reflect the result of the last nulling procedure, so it will be
necessary to perform the nulling procedure again. This is commonplace in the industry, as it is
impossible to measure the depth of the null on a continuous basis without asserting mic kill and
injecting tones.
Level Meters
The Intercom unit contains four, 5-segment LED VU meters on the front panel. The first set displays the
4-wire input levels for Channel 1 as well as the 4-wire output levels for Channel 1. The second set of
VU meters display the input and output levels associated with Channel 2. The nominal 4-wire input
level for either version of Intercom is +4dBu which should correspond to the lower four LEDs for an
input channel turning green with the top LED off (0 LED represents 4dBu). If the input is 6 dB or more
over the nominal input value, then the top LED will light yellow indicating clipping could be on the verge
of occurring. The output VU meters function in the same manner as the input meters. To maintain
accuracy of the meters, the system should always be re-nulled if any of the party-line connections are
changed.

3.2. MIC/Line Inputs (8x) [HB-DC-DBROnly]
The MIC level inputs contain microphone preamplifiers intended for use with low-level microphones or
line-level audio sources. It features adjustable input gain and impedance settings, LED metering, and
individual 48V/12V phantom power (or A-B powered) for each input.
The display area has 2 parts: the VU meter itself, and the two blocks for gain control next to it. The top
block displays the mic gain and the bottom block the line gain.
Along the bottom are the control switches for the mic phantom power, level gain, and to switch between
Mic and Line level for both channels, respectively. The VU meter is set to show a relative value that can
be set to US broadcast audio level of +24dBu FS, EBU R68 of +18dBuFS and consumer level of
+12dBu FS.
12V/48V PH Phantom Power
The phantom toggle switch has 3 phantom voltage modes. By default, all the phantoms will be turned
off or it will be in the previously selected mode before the unit was turned off. The phantom voltage
mode will turn on the direction the toggle switch is pushed. To turn the 12T power on, push the toggle
switch UP. To turn it off push it UP again, or down.
When phantom power is on, the corresponding LED will be lit green. The operation of the switch for
48V phantom is the same, but when the toggle switch is pushed down. The maximum recommended
current rating is 5mA for the microphone connected to each channel input. If the microphone connected
to it draws more current than 5mA the LEDs will turn red. If there is any problem with the phantom
power the LED will turn red. Phantom voltages will not turn on when operated in line mode [L] to avoid
damage to the systems connected to the inputs.
WARNING: The 48 V phantom power biases both pin2 and pin3 to 48V (referenced to pin 1). But the
12T power measures 12V across pin 2 and pin 3.

17 | P a g e
OPERATION
GAIN
The gain is adjusted by toggling the gain switch up or down in the front panel. Push it up to increase the
gain and down to reduce the gain. The gain is displayed in the two gain LED blocks for either line or
microphone as selected by toggling the M-L switch.
There are 9 total gain adjustment steps in Line and Mic modes:
Line mode: -4dB, -3dB, -2dB, -1dB, 0dB, +1dB, +2dB, +3dB, +4dB.
Mic mode: +10dB, +15dB, +20dB, +25dB, +30dB, +35dB, +40dB, +45dB, +50dB
The gain is incremented by 1dB in Line mode and 5dB in Mic mode. For both line and mic modes, the
gain positions which are intermediate to those indicated on the gain LED bar are indicated by lighting
two adjacent LEDs together.
Example: In line mode, when the gain is increased to -3dB from -4dB by toggling the switch up. This
will be indicated by lighting up the LEDs corresponding to -4dB and -2dB. If the gain is increased
again, then the LED -2dB position will light up alone. The LEDs for the gain on mic mode work
similarly.
•Default max audio levels are +24dBu. Contact MultiDyne for other custom levels, e.g., +18.
•Input impedance can also be selected if needed (2.4k, 660 ohm). Contact MultiDyne.
