Apart REVAMP2250 is a professional 2-channel digital power amplifier with 2 x 250 watts output power @ 4 ohms, but is also bridgeable (1 x 500 watts @ 8 ohms). The unit incorporates a high efficient SMPS power supply and outputs with efficient Class D output topology.

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.

• 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 of your amplifier to drive a transformer to drive 100V speaker
systems. This mode applies a highpass filter to channel 2. Filter
characteristics: 12 dB/oct at 50 Hz. Butterworth characteristic.
This setting increases amplifier stability when using a 100 volt
transformer on output 1.

• CH1 BRIDGED CH2: both amps are used in bridge. Audio signal
from input 1 is used.

• Combination CH1 SUB – TOP CH2 with CH2 TRAFO LOAD: this
combination allows a low impedance subwoofer to be used
with 100 volt top speakers. Audio signal from input 1 is used.
This setting increases amplifier stability when using a 100 volt
transformer on output 2.

• CH1 TRAFO LOAD with CH2 TRAFO LOAD: a highpass filter is
applied to channel 1 and 2 to ensure that low frequencies are
filtered. Filter characteristics: 12 dB/oct at 50 Hz. Butterworth
characteristic. This setting increases amplifier stability when
using 100 volt transformers on the outputs.



The digital signal processor inside operates with one simple push button at the back of the unit to select an operating mode (6 presets). An example of a preset is the combination CH1 subwoofer and CH2 trafo load.  In this example you have a low-pass filter for increased stability when using 100 volt transformers on the output, allowing you to use 100 volt speakers as top speakers combined with a standard low impedance subwoofer. With the other presets channels can be bridged, high pass filters can be applied to a channel...

The very intuitive front display shows what is going on with one blink of an eye. Thanks to our own designed automatic protection system (patent pending) with smart use of a compressor/limiter topology we bring our switched mode power supply to an unexpected high level! This manifests itself in a great dynamic power with an unseen musicality and exceptional dynamic sound.

Ease of use, high-tech, reliability and big output power has never been as cleverly combined as in this REVAMP2250 amplifier.
