1.
Output Level Adjust
- Nine multi-turn potentiometers to set the individual output levels for each
frequency band in each channel.

Bypass Mode
- These switches configure the bypass electronics for either two-or-three-way opera-
tion (should always be set to match the speaker configuration). Up (or ON) is two-way; Down (or OFF) is three-way. All switches must be set the same way - either all Up or all Down.

configuration. These must be set to match the speakers according to the chart in the Appendix or the speakers may be damaged.

cates the level is below -54 dB. Green indicates the signal is present at normal levels. Yellow indicates the signal is within
±
0.5dB of the 0dB (300mV rms) reference point. Red indicates that
the signal is over +23dB and in danger of clipping or distorting.
5.
RS-232 Port

cian. Instructions are included in the update package.
