Key Features.

The A504DSP flexibly distributes the total amplifier power in various combinations across four, three or two outputs.  This ensures the amplifier is a highly efficient solution when using some channels for subwoofers and some for mid-top loudspeakers.

The onboard, advanced DSP engine, controlled by a built-in OLED screen with an encoder or by a PC, allows control of input/output routing, high-pass and low-pass filters, parametric EQ Filters, compressors/limiters, noise gates and alignment delays.​
