Power amplifier 4x60W
The pairs of channels 1/2 and 3/4
can operate independently:
• In parallel (input signal of
ch 1 pilots also ch 2);
• in stereo (each channel has
a different signal on input);
• “bridge” (inputs are powered with
the same signal in reverse phase)
both in parallel and in stereo; each
amplier delivers 60W/ 4 0hm while
in bridge mode power delivered by
each pair of ampliers will be
120W/ 8 0hm. Each channel has
volume control, luminous indicators
of the input signal and saturation.
The front panel also has luminous
indicators for operating modes
(bridge, parallel, stereo).
