1 • RCA input connectors: To connect the Pre output leads of the main unit to the amplifier

input. These inputs control the final stages.

2 • Adjustment of the gain of the Input: Adjusts input sensitivity of amplifier,

which can vary between 200 mV and 4V.

To adjust sensitivity, proceed as follows:

a)Set the volume control of your unit to 3/4 of its maximum output

b)Adjust the amplifier input gain controls until the maximum possible acoustic

pressure has been obtained without any distortion.

3 • Stereo/Mono switch: changes the output mode of the amplifier between

Stereo and Mono. If Mono is selected, the corresponding Left (mono) input is

used to operate the amplifier.

4 • Crossover switch: selects the output mode of the amplifier by activating the Low-pass or

High-pass filter.

a)Flat: the amplifier will reproduce the complete audio

range in relation to the signal applied to the input.

b)Low-pass: activation of the low-pass filter, i.e.

determination of the finishing-point of the low frequencies

present at the outputs .

c)High-pass: activation of the low-pass filter, i.e.

determination of the starting-point of the high frequencies

present at the outputs.

5 • Continuous adjustment/control of the Low-Pass or High-Pass

frequencies: once the low-pass or high-pass filter is inserted, the crossover

frequency can be adjusted in continuous mode between 30 Hz and 600 Hz.
