NOTE

• If the surround speakers or the center speaker level of the

system (page 13) and the DOLBY DIGITAL SURROUND (page

• While “S-R” or “S-L” is displayed, both surround speakers output

the noise signal together. However, only the sound level of one
surround speaker displayed as “S-R” or “S-L” can be adjusted.

• When the sequencer outputs a noise signal, a clicking sound

might be heard from the speakers due to the characteristics of
the circuit. This is not malfunction.

The center speaker helps achieve precise sound positioning

the front speakers. The delay is initially set to 20 ms (milliseconds).
