INPUT CONNECTORS
The Input section has four different styles of input
connections for line-level audio signals. Choose one which
suits your system the best:
6. Combination XLR/TRS connector.
This
can accept a male balanced XLR connector, a
balanced TRS or unbalanced TS 1/4" connector.
7. Phoenix (Euroblock) connector.
This
three-pin connector accepts the positive, negative
and ground terminals of a balanced audio line. It
accepts a push-in connector for easy installation.
8. Terminal strip.
This three-terminal connector
accepts the positive, negative and ground
terminals of a balanced audio line. Secure the
connections with the screws.
Each input style is designed to accept balanced or
unbalanced line-level signals. The input can be configured
by means of the DIP-switch (see below).
9. GAIN pot and OL (overload) LED
This screwdriver-adjustable rotary potentiometer acts as a
trim control, and a red indicator LED will light 3 dB before
clipping. With normal source material playing, adjust the
pot until the LED lights only occasionally during the loudest
moments of your program.
10. Input DIP switch
This three-pole DIP-switch allows you to configure all four
input types, as shown in this table and the details below.
DIP switch details:
1. Parallel Enable. Select UP if you want there to be
an output from the Parallel Output. This allows you
to send a line-level copy of the audio input signals
to other components or amplifiers in your system.
Select DOWN if you are not using the Parallel
Outputs.
2. High-pass filter enable. The default position is
enabled (DOWN). This rolls off the low frequencies
below 120 Hz, at a rate of 12 dB per octave. Use
this to reduce low frequencies, such as from low
bass notes, microphone handling and stage noise.
It is useful when using smaller speakers that do
not reproduce the low frequencies well.
3. 10 dB pad enable. Select UP to reduce the input
level by 10 dB.
