DAD IDEA2804 Amp-DSP control 4×400 / 700W 8/4 Ohm – 2x1250W 8 Ohm / 100V

Beschrijving

DAD (meer)kanaals versterkers zijn prijs technisch een goed alternatief geworden voor bv Monacar/IMG.

En de DSP series hebben als extra een eigen DSP aan boord !

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 4×400 / 700W 8/4 Ohm – 2x1250W 8 Ohm / 100V
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

“BRIDGE” MODE
Connection mode: Set the operation mode to
“BRIDGE”.
With the “BRIDGE” setting (“BRIDGE”) the signal is
amplified by the channels CH1 and CH2 added together and sent to a single output (“BRIDGE”). The
signal is controlled via the CH1 DSP
With the setting of the “LINK MODE” selector on “1
IN 4”, the CH1 inputs are in parallel.
The signal is controlled via the respective DSPs of
the CH1 channels
NOTE – Minimum load 8 Ohm (when the amplifier
works in impedance systems)!
NOTE – This mode allows amplifiers to operate in
100V systems with a maximum output power of
1250W.
