outputs select the position "2CH" and connect the outputs to the amplifier inputs marked with the
letters A / E (left) and B / F (right). Then select the position "4CH" in order to have 4 output
channels, A, B, C and D, respectively, to drive 4 speakers. You can then activate (ON) the
different sections of the built-in electronic crossover to obtain the High-Pass outputs A and B and/
or the Low-Pass outputs C and D.
NOTE: In case a preamplified output is needed to control another amplifier, the RCA-connectors
C and D marked BY-PASS and carrying a unitary gain output signal can be used.
The By-Pass output is active only with the "2CH
IMPORTANT NOTE: Both input sensitivity adjustments are activated and operate independently
on the respective outputs.

multi-amplifying system. There are 3 output channels, 2 stereo channels A and B, and a third
channel F with a single bridged mono signal.
In case you want to use the built-in electronic crossover, the outputs A and B can be connected
to medium-high speaker systems by placing the High-Pass selector in the ON position , whereas
by placing the Low-Pass selector in the position ON a woofer system or a powerful subwoofer
can be connected to the mono output F.
IMPORTANT NOTE: Both input sensitivity adjustments are activated and operate independently
on the respective outputs.

powerful 2-channel stereo system with the output channels E and F.
On activating the built-in electronic crossover, Low-Pass ON with this configuration, only the low
frequencies are output for driving two powerful subwoofers.
IMPORTANT NOTE: With this configuration only one of the two input sensitivity controls (the
right one) is activated for the adjustment of the signal at the E (left) outputs.
