MOUNTING
When rack mounting, it is advisable to allow 1 rack space above and below
the amplifier. When multiple amplifiers are mounted in a rack, exhaust fans
should be used on the rack. Airflow for cooling the amplifier is by convec
-
tion from bottom to top and by fan left to right.
OUTPUT CONNECTIONS
The output terminal strip accepts wire sizes from
16-22AWG (1.5mm2 - 0.35mm2).
The following table should be used as a guideline for cable sizes. Regula
-
tions in your area may require different gauged wire and should be checked
before using.

NOTE: Only connect one output - either Distributed Line
or Low Impedance.
The LINE output XLR can be used to connect up to 6 booster amplifiers.
Balanced input wiring (shielded pair cable) is recommended.
NOTE: When wiring the LINE output as unbalanced, Pin2
should be wired as hot and Pin1 should be wired as
ground/shield. Do not wire Pin3.
The REC output wiring should be kept as short as possible.
INPUT CONNECTIONS
For wiring balanced in,
pin 2 is hot. Unbalanced
wiring on the microphone
inputs is not recommended.

(shielded pair cable)
is recommended.
Unbalanced RCA wiring
should be keep as short
as possible.
