4. REAR PANEL FEATURES
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 # | Purpose | DOWN | UP |
1 | Parallel Enable | OFF | Enabled |
2 | High Pass Filter | Enabled | OFF |
3 | –10 dB Pad Enable | OFF | Enabled |
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.
