SETTINGS AND SELECTORS
OUTPUT MODE SELECTOR WITH 2 INPUT CHANNELS AND A BY-PASS OUTPUT
a) "2CH input" "4CH output" MODE: As your head unit is equipped with only two pre-amplified
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 the different
sections of the built-in electronic crossover independently to obtain the High-Pass outputs A and
B and/or the Low-Pass outputs C and D.
IMPORTANT NOTE: Both input sensitivity adjustments are activated and operate independently
on the respective outputs.

b) "2CH input" "3CH output" MODE: This configuration uses a single 44.13 amplifier as a 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 80/120 Hz position,
whereas by placing the Low-Pass selector in the position 80/120 Hz 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.

c) "2CH input" "2CH output MODE: This configuration uses the amplifier as a traditional and
powerful 2-channel stereo system with the output channels E and F
On activating the electronic crossover section Low-Pass 80/120 Hz in 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.
