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 (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 INPUT" configuration.

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 44.05/44.07 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 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.

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 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.
