APPLYING POWER TO THE SYSTEM

After all wiring between the base station or audio interface, microphone and MS-1 Mute Switch is complete, apply power with the power supply, (included) with the APR-1 Base Station or audio interface.

1. First connect small end of 12Vdc Power Supply to the 12Vdc Power Jack[10], then plug power block into a standard 120Vac wall outlet or power strip.
2. Turn “ON” power to APR-1 by rotating the Power-Volume Knob[1] clockwise. Adjust volume of audio by rotating the knob either clockwise to increase or counterclockwise to decrease.
3. The APR-1 will power up both the remote microphone and the MS-1 Mute Switch

CONNECTING MICROPHONE DIRECTLY TO A RECORDER
The microphone maybe connected directly to a recorder without the use of an interface adapter or base station

1. Connect +12Vdc power supply to terminals “A” and “C” of the MS-1. Connect +12 Vdc to terminal “A” and -12Vdc or ground to terminal “C”.
2.  Connect terminal “B” of MS-1 to terminal “A” of of microphone (shown in drawing).
3.  Connect terminal “C” of MS-1 to terminal “C” of microphone.
4. Run 2 wires from the microphone to the recorder
   a. Connect terminal “B” of microphone to the positive tip of the 3.5mm mono or .RCA plug (this plugs to the recorder input)
   b. Connect terminal “C” of microphone to the negative or ground of the 3.5mm mono or RCA plug

TESTING AND OPERATION OF SYSTEM

Make sure the Microphone is active. Top part of MS-1 switch must be pressed IN and the Red Rocker Switch illuminated.

1. Create some sound (radio, someone speaking, etc) near the microphone. The sounds will transmit to the APR-1’s built-in speaker[9] (see page 6). Adjust the volume of audio by rotating the volume knob clockwise to increase, or counterclockwise to decrease.
2. To mute the system, press the lower part of the rocker switch IN. The lighted switch will go dark, indicating power if OFF and the microphone is DISABLED.
3.  Again create some sound. There should be no transmission of audio through the base station (APR-1, etc).
4. If the microphone is directly connected to a recorder, turn ON the recorder to record the audio from the microphone
