MIC LEVEL
OUTPUT:
LINE OUT:
A 3-pin XLR audio connector which provides a balanced, low impedance (200
Ohm), 10 millivolt, microphone level output suitable for house sound systems,
microphone mixers and other units requiring a microphone level input. Pin 1 is
Ground or Shield, pin 2 is Audio High, and pin 3 is Audio Low. If using an
unbalanced load, pin 1 is Ground, pin 2 is Audio and pin 3 is not used. The output
level at this jack varies with the setting of the WIRELESS MIC VOLUME and AUX
VOLUME knobs.
An RCA phono jack that provides a 1 Volt output signal to drive line level inputs of
tape decks, cassette players and other P.A. systems.
AUX IN: An RCA phono jack input used for playback of line level outputs from tape decks,
cassette players and other P.A. systems.
AUX VOLUME: This control adjusts the volume of the MIC OR AUX IN and the AUX IN inputs.
MIC OR AUX IN: This jack is a standard 1/4" phone jack and will accept a dynamic microphone.
WIRELESS MIC
VOLUME:
This control adjusts the volume of the built-in wireless microphone system.
knob does not affect the MODULATION LEDs located near it. This
MODULATION LEDs: The -20 and LIMIT Leds continuously indicate the modulation level (audio level) of
the received signal from the transmitter and are used when making initial
adjustments to the transmitter.
See items 10 and 11 in the section on
"OPERATING INSTRUCTIONS" on page 10.
RF LED: A green LED lights when the companion transmitter is turned on and there is
sufficient signal for good system operation. Internal circuits monitor both signal
level and interference levels and decide if the transmitted signal is strong and
"clean" enough for satisfactory operation. If not, the RF lamp will go out and the
receiver will "squelch", shutting off the sound output. This action is automatic and
requires no user adjustment.
