Front Panel
1. Headset connector
4-pin XLR Male or 5-pin XLR female connector
EARPHONE: Dynamic 50-2000 ohm
MICROPHONE: Dynamic 100-600 ohm
The wiring of headset is as follows:
Pin 1--Mic common
Pin 2--Mic hot
Pin 3--headphone common
Pin 4--headphone hot
Pin 5—Null
2. Panel Mic Connector
This is a double-purpose connector, supports both of unbalanced input
microphone with XLR plug and 1/4inch plug.
The wiring of 3-pin XLR microphone is as follows:
Pin 1 -- Mic common
Pin 2 -- Mic hot`
Pin 3 -- parallel connected with Pin 2 internal
3. Mic Select Switch
Set the Mic select switch to select whether the panel microphone or the headset
microphone is active.
4. Panel Mic Gain
It is used to increase or decrease the gain for panel microphone to achieve proper
microphone output level. It has no effect on the sensitivity of the headset
microphone.
Note: For earlier models, this adjustment button is in cabinet, and you can find
this adjustment potentiometer at the right side of front panel after opening the
top cover of cabinet. The microphone is set according to the Electret type before
delivery. If the type of panel microphone is changed, re-adjustment is required.
5. Mic Switch (Mic)
That turn up or down the Mic switch handle will send microphone signal intercom
line after amplification. When the switch is turned to ON or PTT, the LED (6)

above will light. The settings are as follows:
ON: The selected microphone is activated, the switch is self-locked.
OFF: The selected microphone is off.
PTT: The selected microphone is activated, release and reset.
When the front panel speaker is turned on, pressing Mic button will reduce the
speaker output level about 6dB and help minimize feedback.
6. Mic LED
This LED lights when Mic switch (5) turns to ON or PTT.
7. Call Switch
Send call signal from host to the channel. Turn up or down the handle of call
switch, the LED (8) above selected channel will light (RED). This switch is without
self-locking function, release and reset.
8. Call LED
This LED will light under two cases: a) called: when the call signal from
communication channel is received; b) call: the call switch (7) is turned on.
9. Power Switch
Power switch is turned on, Power LED (10) light.
10. Power LED
This green LED lights on when the SPK-200 is receiving AC power. This LED will
flash when the SPK-200 senses a short or overload on the circuit. When the fault
is removed, the power supply will automatically reset and LED
11. Sidetone zero-adjusting
The SPK-200 uses full-duplex audio (the same as a conventional telephone line) in
which the talk and listen audio are sent and received on the same line. Thus,
when you talk on a channel, you will also hear your own voice back in the speaker
or headphones. This is called sidetone. If you are using the SPK-200 with a
microphone and speaker, sidetone could cause unwanted feedback, since the

microphone may pick up your returned voice audio and reamplify it. This could
also happen if you are using a headset where the ear cushions do not completely
cover the ears, although it is probably much less likely. In either case, you should
minimize the amount of sidetone.
Typically, different sidetone null settings are needed depending upon whether you
are using the gooseneck panel microphone along with the speaker or not. Use one
of the following procedures to correctly set the sidetone level controls.
A) Sidetone Adjustment Procedure for Gooseneck Microphone with
Speaker turned on:
1 Turn on the Mic switch. Set Mic select switch to panel.
2 Turn the level control to a comfortable level.
3 Speak into the microphone while turning the sidetone null control slowly back
and forth. There should be a point where your voice (and any accompanying
acoustic feedback) is the lowest. This is the null point.
B) Sidetone Adjustment Procedure for Headset:
1 Turn on the Mic switch. Set Mic select switch to headset.
2 Turn the level control to a comfortable level by having someone talk to you from
another station.
3 Speak into the microphone while turning the sidetone null control slowly back
and forth. There should be a point where your voice (and any accompanying
acoustic feedback) is the lowest. This is the null point.
C) System Sidetone Adjustment
1 Turn off all the microphones on sub-stations and beltpacks.
2 Followed by A) and B), adjust sidetone on MS-800 main station.
3 Turn on the microphone on sub-station and beltpacks one by one, and then
adjust the Sidetone to satisfied level.
12. Remote Mic Kill Switch (RMK)
The Remote Mic Kill (RMK) switch will turn off the microphone of every beltpack
remotely. If the Talk Functions of a large number of beltpacks have inadvertently
been left activated, incidental noise and talking can make it difficult or impossible
