CONTROLS AND INDICATORS

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	4V	0,2V
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 L(mono)			ST
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.

Flat	Low High
	20Hz	20kHz

b)Low-pass: activation of the low-pass filter, i.e. determination of the finishing-point of the low frequencies present at the outputs .

Flat Low High

20Hz 30 > 600Hz

c)High-pass: activation of the low-pass filter, i.e. determination of the starting-point of the high frequencies present at the outputs.

Flat	Low High
	30 > 600Hz	20kHz

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.
