Instruction manualREVAMP2250

• CH1 SUB – TOP CH2: frequencies below 100 Hz are sent to the

sub channel (CH1). Frequencies above 100 Hz are sent to the

top channel (CH2).The Filter slope (12 dB/oct or second order

Butterworth characteristic) and frequency (100Hz) are ﬁxed. The

Audio signal from input 1 is used.

• CH1 TRAFO LOAD: Use this mode when you want channel 1

of your ampliﬁer to drive a transformer to drive 100V speaker

systems. This mode applies a highpass ﬁlter to channel 1. Filter

characteristics: 12 dB/oct at 50 Hz. Butterworth characteristic.

This setting increases ampliﬁer stability when using a 100 volt

transformer on output 1.

• CH2 TRAFO LOAD: Use this mode when you want channel 2

DSP features and audio signal routing:

There are 6 possible DSP settings and 2 available combinations.

The settings will be memorized and recalled when the unit is

powered up.

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 !!!

6. DSP setting led display: the leds show which of the DSP settings

or combinations have been activated.
