SURROUND OUTPUTS
Your processor has multiple surround processor outputs for use with external amplifier(s) or powered speakers.
The Reference 20 Plus processor allows further processing of the surround channels for the precise decoding of
Dolby Digital Surround EX and DTS-ES soundtracks via matrix decoding.
Here is a typical processor surround output setup
:
Subwoofer Output -
Connect an RCA cable from the processor’s SW output (part of the surround outputs). If
your subwoofer does not contain its own amplifier you will need to purchase an external B&K or other power
amplifier. Connect the processor’s SW output to the audio input of the external amplifier. Connect the external
amplifier’s speaker output to your subwoofer.
