AMX-20-DSP4-ACD 


The preamp mixer AMX-20-DSP4-ACD is a modern automatic digital mixer with signal processor DSP with highest sound quality.

The digital automatic preamplifier is equipped with 20 inputs and 4 outputs, phantom power, 10 input and 5 output PEQ, HPF filter (100Hz), MIC./LINE, digital automatic system DIGITAL SIGNAL DELAY FIELD with BARRIER -GATE, GATE-OPEN & GAIN-CONTROL, de-esser, MP3 player with BT receiver, audio matrix and more


With compressor expander limiter function.

The AMX-20-DSP-4ACD preamplifier is specially designed for professional sound reinforcement applications in acoustically difficult buildings (building acoustics).

This professional pre amp is equipped with most modern technologies and is used where most other devices do not produce positive results or an entire rack of system components would have to be built to provide a reasonable acoustical result.

The 16 universal inputs can be switched by DIP switches between MIC and LINE sensitivity. Each of the 16 universal inputs has switchable phantom power and a HPF filter (100 Hz).

The universal inputs are equipped with a switchable automatic microphone system, DIGITAL SIGNAL DELAY FIELD system (DSDF). The activation only of the microphones being addressed is automatic and is controlled and monitored by the processor system (DSDF). Unnecessary open microphone channels are closed.

The input matrix (DIP switches) can be used to assign the input channels 1-16 to the outputs MAINSUM-2 and / or the output MAINSUM-3.

The built-in MP3 player module with BT receiver (including IR remote control) has inputs for USB sticks and a SD memory card and will optimally accompany you during the operation. The integrated BT receiver supports all popular Bluetooth-enabled devices and allows you to wirelessly transfer music or pre-made texts from your mobile phone, PC or MP3 player to the amplifier and play it.
