Macrom 44.07, 44.05 owner manual Output Mode Selector with 4 Input Channels, Front Rear

SETTINGS AND SELECTORS

OUTPUT MODE SELECTOR WITH 4 INPUT CHANNELS

a)"4CH INPUT" "4CH OUTPUT" MODE: As your head unit is equipped with four pre-amplified outputs select the position “4CH” and connect the outputs to the amplifier inputs marked with the letters A (left), B (right), C (left) and D (right). Thus, the amplifier can be used as a 4-channel stereo system, front section A and B and rear section C and D, by using the speaker outputs A, B, C and D. You can then activate (ON) independently 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.

b)"4CH 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 which can then be balanced by means of the fader control of your head unit.

In case you want to use the built-in electronic crossover, it is possible to connect medium-high speaker systems to the A and B outputs by placing the High-Pass selector in the ON position, whereas a woofer system or a powerful subwoofer can be connected to the section F by placing the Low-Pass in the ON position.
