The red

clip

LED also indicates short-circuit at the output. Although

this protection is provided, it is dangerous that the amplifier remains

in this situation for a long time. In case of a short-circuit, turn off the

amplifier while examining any equipment connected to the

amplifier's output, together with the connections and cabling.

This LED also indicates an impedance load that is too low.

Models E-2 and E-4 use arrays of self-managed amplification cells,

each of which independently features a full set of protections,

which makes the amplifier virtually indestructible, protecting it

against AC supply oscillations, short-circuits, thermal runaway and

transient temperature peaks. In case of overheating, the amplifier

will disconnect the output, but there is no LED indication that the

protection is active. When the amplifier has cooled down, the

output will be connected and operation will resume.

SAFEGUARD

LED (E-8, E-12 and E-20 only)

When the output is disconnected by the amplifier's protection, this

orange LED is on. The control circuit for the activation has some

degree of built-in

hysterisis to avoid turn-

on and off oscillations.

If the amplifier exceeds

normal temperature

levels, the

SAFEGUARD

LED will turn on and the

output will be

deactivated via a relay.

Once cooled, the LED

will turn off and output is reactivated.

DC detection is also provided. Since it may severely damage

speakers, the amplifier will deactivate the output in the event that

DC levels are too high. If load impedance is too low, the amplifier is

also deactivated.

When the amplifier is switched on, the output is also deactivated

for a few seconds to prevent dangerous transients from damaging

the speakers, and the

SAFEGUARD

LED is on until the amplifier is

ready for use.

D) SIGNAL PRESENT LED INDICATOR (models E-2 and E-4)

This green LED shows the presence of signal at the amplifier's

inputs regardless of the position of the volume control.

E) IDLE LED

When lit, this green LED shows that the amplifier is on.

F) LEVEL CONTROLS

Volume levels for each channel

can be adjusted by using the

knobs found on the front panel.

The effect is the same as

adjusting the gain of the

amplifier. The maximum level

is obtained the INPUT LEVEL

rotary potentiometer is rotated

fully clockwise.
