MUTING FUNCTIONS
VOX - VOICE ACTIVATED MUTING - The Amplifier is equipped
with a DUAL noiseless, fast acting Logic Muting Function.When a
signal is present at the INPUT 1 or INPUT 2 Input, either from a
Microphone or a Telephone Paging source, the Muting Function is
activated muting the source present at the INPUT 3 and as well as
the source present at the PROGRAM input(INPUT 2) if selectively
activated. Once the Signal (paging) is terminated the program is
automatically restored on all muted inputs.
FOR THE VOX ATTACK AND DECAY TIMING REFER TO THE
FIG. 11B DIAGRAM.

PROGRAM INPUT (2)
The PROGRAM input is provided for high level pro-
gram source. The output from a Satellite Receiver
Tuner, Tape Cassette Deck, CD Player or other high
level program source may be directly connected to
this input.
PROGRAM INPUT SENSITIVITY ATTENUATOR
The PROG Input is equipped with a Sensitivity
Attenuator that allows the interface of the PROG
Input with Devices having a wide range of Output
Levels.
TYPICAL OUTPUT LEVEL OF MUSIC DEVICES:
Satellite Receivers = 1 to 5 Volt
Digital Tuners/Receivers = 100 to 300 Mv
CD Players/Changers = 2 to 3 Volt
Tape Decks = 500 to 700 Mv
By adjusting the PROG Input Sensitivity to the level
that matches the device used the correct interface
with the Amplifier is achieved resulting in lower over-
all distortion and better frequency response charac-
teristics.
STEREO SUMMING
Since most Music Source Devices provide a Stereo
Output the Amplifier is equipped with two Jacks for
the PROG Input (L and R).The two Inputs are inter-
nally buffered and electronically mixed to Mono.This
system ensures that the Music Device is properly
loaded and that the Stereo Signals are correctly
summed (L+R) to Mono without distortion.
CABLE
To connect the music source devices to the PROG
Input use two single conductor shielded audio cable
terminated in a single prong phono plug on both
ends.

CONNECTING TO AN EXTERNAL EQUALIZER
The Amplifier is equipped with an External Equalizer Link
to allows the use of an External Equalizer for applications
requiring
Frequency Selective Acoustic Correction
. The
Amplifier is furnished with the two jacks of the Link bridged
by a SELECTOR SWITCH. When the EQ LINK Switch is
the ON position the internal Preamplifier to Amplifier Link
is broken allowing the insertion of an EQ. Connect
Equalizer as per Diagram in Fig. 15.
INSTALLATION TIPS
1) Use high quality, short length audio cables and position
the Equalizer in close proximity to the Amplifier. Avoid
mounting the EQ on top of the Amplifier unless is Rack
mounted.
2) Be sure that the Amplifier input controls and the EQ level
control are set at zero prior to turning the system On.
3) The Amplifier Bass and Treble controls should be set to
the middle detented position (0= linear response position).
4) Carefully adjust the EQ Level Control to avoid distortion
caused by excessive signal boost.
5) Follow the instructions supplied with the Equalizer.
WIRING
To connect to an External Equalizer use two (2) single con-
ductor shielded audio cables terminated in a single prong
phono plug on both ends.

lowing the diagram and set INPUT MIC/PROG Switch to PROG.
