INSTALLATION AND WIRING
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
(REFERENCE 12) is the IN position the internal
Preamplifier to Amplifier Link (Reference 13) is broken
allowing the insertion of an External Equalizer.
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 TONE BY PASS SWITCH (Reference 17)
should be set to ON ( 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.

BRIDGING TWO AMPLIFIERS
The MIX BUSS (Reference 15)
allows two Amplifiers to be bridged
and share all inputs.
All signal sources connected to all
the inputs are common to the output
of both amplifiers. Muting and level
controls operate in exactly the same
way as if only one amplifier was
used.
