connected in parallel for multiple Audio-Pods driving one SSR if all modules are
set for constant SSR operation. IMPORTANT: Maintain SSR output polarity
considerations between the Audio-Pods or damage may result. If multiple
Audio-Pod SSR outputs are used for driving a single LED indicator, a 220 ohm
series resistor between the positive outputs and the LED is recommended.
7. If desired, connect the remote control wiring to the “RMT CONT ON/OFF” and
“GND” terminals. Either a logic low or contact closure will turn the microphone
on. A logic high or open contact will turn the microphone off unless local
control has it locked on. It is recommended that an “open collector” logic
interface or isolated normally open contacts be used.
8. The “LOC CONT ENABLE” jumper that is connected to “GND” with the factory
installed jumper enables the front panel push buttons and “COUGH” function.
To disable the local microphone on-off switch and cough functions, remove the
jumper between the “LOC CONT ENABLE” and “GND” terminals. The Mic ON-
OFF function will now only work using the remote control input.
9. If the preamplifier option has been selected and phantom powered
microphones are to be used, set the “PHANTOM POWER” switch to the “ON”
position. (switch to the left position) The amber LED will indicate that phantom
power is on. This switch setting may be changed at any time without causing a
damaging “thump” in the output.
Setup
Connect the AC power cord to an 115VAC outlet. The LED indicator on the power
supply should light as well as the “MIC OFF” buttons on the Audio Pods.
Microphone Section with the mic pre-amplifier option only:
1. The Audio-Pod microphone gain is factory preset for the average dynamic
microphone and there may not be need for any adjustment. If the gain is set
too high or a Condenser or an Electret type of microphone is used, the rear
panel “MIC GAIN” control setting will need to be reduced.
A. If a Condenser or Electret type of microphone is being used turn the
Phantom Power switch to ON. The LED indicator will light when the
switch is in the ON position. It is advisable to disable the phantom power
supplied by the mixing console unless other such microphones are being
used directly connected to the console. The presence of up to 48 volts
DC on the output of the Audio-Pod will do no damage.
B. Set your mixing console for normal input and output, press the Audio-Pod
“MIC ON” button. Adjust the “MIC GAIN” control, using the supplied
trimpot tool, counter-clockwise (less gain) for the proper VU indication on
your console. Note that the “MIC GAIN” control is very sensitive to
adjustment at the most clockwise end of its range.
C. IMPORTANT: Due to the large amount of available gain in the Mic pre-
amp section it is possible to overpower the FET Mic On-Off switching
circuit if the “MIC GAIN” control is set for excessive gain. To assure that
you have not exceeded the capabilities of the switch, press the “MIC OFF”
switch and speak loudly into the microphone. If modulation peaks cause
an output you have the gain set too high and it should be reduced
accordingly.
