PROFESSIONAL POWER AMPLIFIER

Operation

1. Removable rack ears for 19 rack mounting.

2. Power switch: after switching on the power, the power led will

light up after approx 1 second. The limit-muted leds will light

up for a few seconds to avoid excessive power on pop noise.

3. Power led

4. Channel 1 status led bar and mute switch: when the mute

switch is pressed, the orange “LIMIT – MUTED” led will light

up. This led will also light up when the internal limiter is

activated to avoid the ampliﬁer from being overloaded by high

input signals. The “CLIP – OVERLOAD” led indicates that the

power ampliﬁer is clipping: reduce the input signal at once

whenever this occurs !!! The green “SIGNAL - -40dB” led

will light up when an input signal is present. The red “INPUT

– OVERLOAD” indicates that the input is being overloaded.

Reduce the incoming signal at once !!! This led will blink

when temperature protect is active: in this case the ampliﬁer

will automatically reduce the output power to avoid further

overheating.
