1 • A / B LEVELS: A channels (Left and Right) and B channels (Left and Right) input sensitivity adjustment. It
features 2 ranges, Hi from .3 to 1.2 VRMS and Low from 1.2 to 4.8 VRMS. By pushing for three seconds on
the knob you can change the range. To see voltage value and range check the ASC display. Those controls
are also available if ACNet sofware is used.
2 • 4 / 3 / 2 Ch Mode: Setting the switch on 4 Ch, the amplifier has to work in 4 channels mode, switching on
3 Ch the B channels will set in mono (Bridge), in 2 Ch position the A channels will set in mono too and the
TH quattro has to work in Dual Mono mode.
3 • IN A / IN B: This switch allows to drive the A channels through the IN A inputs and the B channels through
the IN B inputs or to drive the amplifier through the IN A inputs. In 2 Ch mode you must use the IN A inputs,
IN A Left will drive the A channels ( mono) and IN A Right will drive the B channels (mono).

How to move from one sensitivity range to another
TURN THE KNOB TO REGULATE THE LEVEL OF THE A CHANNELS.
PRESS THE KNOB FOR 3” TO CHANGE THE RANGE FROM HI TO LO AND VICE VERSA.
IF YOU ARE USING THE IN B CHANNELS INPUT, REPEAT THE TUNING STEP ON THE B LEVELS KNOB.

between the two levels could be dangerous for your system.
