It is suggested not to obstruct them.

5.  Operation Mode Selectors

These are three-position switches that allows you the selection of BRIDGE, STE

-

REO or PARALLEL operation modes for the two amplifier sections (CH1 / CH2 - 

CH3 / CH4).

6.  Link Switch CH3/CH1

By putting this switch in the ON position, you can configure the amplifier with 1 

input and 4 outputs in PARALLEL MODE and with 1 input and 2 outputs in BRIDGE 

MODE. In both cases CH1 must be the input signal. The volume adjustment for 

the outputs will be made via CH1 and CH3 level controls.

7.  Ground/Lift Switch

The ground/lift switch eliminates unwanted hum and buzz by interrupting the 

ground loops between equipment, preventing current flow along the cable shield 

between two devices.

8.  Gain Sensitivity Selector

This 3-position switch allows you to select the sensitivity of the input signal so that 

you always have an adequate margin (Headroom) between the nominal level of a 

signal and the maximum level that the amplifier can handle correctly before satu

-

ration occurs with consequent signal reduction. This selector allows to choose, as 

the input sensitivity,  0,775V, 1,4V or 2,5V.

9.  Limiter Switches

These switches are used to activate (ON - Green LED ON) or disable (OFF- Red 

LED ON) the protection of the input compression circuit. This protection function 

is used to reduce the possibility that one or both of the channels (CH1 / CH2 - 

CH3 / CH4) are clipping or overloaded and therefore to avoid damage to the 

power amplifier in case of malfunction of the input device (Mixer, CD Player, etc.).

10. Filter And Frequency Sections

These sections are provided by a three-positions switch, three LED and a knob in 

order to select the filter type and cutoff frequency corresponding to each channel. 

When the switch is in OFF position (Green LED ON), it means that not any filter is
