IDEA2804

The innovative IDEA series of amplifiers with integrated DSP of 2 or 4 channels combined in a double rack unit audio power and control. With a complete interface for managing DSP parameters, they are the ideal choice for engineers, installers and anyone else who wants flexibility and reliability.

They are also the ideal complement to the ARK and AIR series of loudspeakers.

The Bridge / 100V mode allows the use of these amplifiers even for constant voltage lines.

The IDEA series is equipped with a 52-bit Analog Device DSP with 48 kHz sample rate, with independent parameter control for each channel. Preset files available for ARK and AIR system configurations.

Features:

Amplifier with DSP control 4x400 / 700 W 8/4 Ohm - 2x1250 W 8 Ohm / 100 V

Can be used for low impedance loudspeakers (min 4 Ohm), both for 100V constant voltage lines

Specific presets available in the appropriate download section.

Editable presets for DJs, live sound and commercial installations

Remote control with RJ45 port via ARK485UR accessory

2-unit rack design
