Processor Use: Configuring the Processors (Discrete 2.1 continued)

Example 1- Discrete 2.1 (continued)

The Subwoofer Processor is next. In Discrete Mode, the Subwoofer Processor’s input signal comes from the Input 3 XLR. Input 3 is routed to the Subwoofer Processor’s IN1 block (see example, below). The IN2 block is not placed when operating in Discrete Mode. An example of a typical Subwoofer configuration might look something like this:

This configuration has a high- and low-pass filter that limit the overall frequency response and equalization to compensate for enclosure and room responses. The low-pass filter is usually tuned to remove any overlap in frequency response of Subwoofer and Top Boxes.

Discrete 2.1 Checklist:

1- Configure Top Box Processor.

2- Configure Subwoofer Processor.

3- Set Mode Switch to Discrete.

4- Connect the two main channel inputs to CH1 Input and CH2 Input XLRs. 5- Connect the subwoofer channel input to the Input 3 XLR.

6- Test and adjust as required.
