Outputs
The two Speakon connectors are automatically configured with a visual indication of the current wiring.
Configuration can be made while the system is operating.
Sub On = 3 amplifier channels :
The two PS Stereo channels are assigned to poles 2+ and 2-
on the L & R Speakons. A single PS LED lights up on each
Stereo channel.
The LSub channel is Mono L+R summed and assigned in
parallel to poles 1+ and 1- of both Speakons. The LS LED
lights up.
Sub Off = 2 amplifier channels:
The two PS Stereo channels are assigned to poles 2+ and 2- on the L & R Speakons. Two PS LEDs are
lighted on each channel. Poles 1+ and 1- of both Speakons are disconnected. The LS LED is off.
Sub Bass Channel
The LSub On Switch automatically reconfigures the PSAmp according to its two operating modes :
Sub On = 3 amplifier channels :
2 x 430 Watts into 8 Ohm channels feed two PSs in Stereo.
1 x 850 Watts into 4 Ohm channel feeds the LSub in Mono L+R.
Sub Off = 2 amplifier channels :
2 x 850 Watts into 4 Ohm channels feed two or four PS10s in Stereo.
The 1700 W power capability of the PSAmp is always used whether or not
the LSub is operated. The Sub amplifier channel is rerouted to the PS10s in
the Sub Off operating mode. In both cases the installation is always
stereophonic.

Level control

The Level control operates simultaneously on all 2 or 3 channels according to
configuration.
The LSub Level control adjusts the level of the LSub relative to the PS when Sub is On.
Fuses and Mains
115/230 V mains Voltage selection, Main fuses and Earth-Lift configuration are located under the safety
