Microphone Placement
Place the MX690 within 1.5 m (5 ft.) of a talker. Aim the
microphone toward the talkers and away from loudspeakers and
noise sources. Use one microphone for every two talkers. Pickup
angle with a cardioid cartridge is 130° at –3 dB.
Note: To minimize RF interference, maintain a distance of at
least 0.3 m (1 ft.) between transmitters. In case of interference,
increase the distance between transmitters or change channels.
Receiver
Make sure the receiver is within sight of the transmitter. Do not
place receiver behind a metal barrier or any reective surface.
