Description

Overview

INTEGRAL-MA1004 is a 4CH (4x250W at 4ohm), 2U rack matrix-amplifier intended for permanent installation with integrated processing DSP (4 analog inputs, 8 analog outputs) and DANTE (4×4) digital Audio. Control, configuration and management of the amplifier shall be done via ALMA software over IP or using Open Sound Control (OSC) protocol. DANTE audio channels can be processed and injected back into the network if needed. The amplifier can be used with Lo Impedance lines or Hi Impedance 100V/70V lines.

Priority capabilities, full matrix and routing options make this unit essential as the ”brain” of any type of installation. The internal memory resources allow to store more than 100 “global presets” and more than 200 “output channel presets” (speaker presets). A bank of output channel presets with specific processing parameters for all DAS Audio speakers is included allowing the users to configure each channel independently. For instance, it would be possible to recall for amp 1 the preset of Q-23T, for amp 2 the preset of Arco-4T, for amp 3 the preset of Q-10 etc.

The unit includes an OLED display (1.54”) with control knobs for intuitive and easy navigation as well meters to monitor signal levels. Basic parameters can be accessible via front panel control knobs; input and output levels, global preset recall, output channel preset recall, mute, source selection, link manager functions, priority enabling etc.

Two of the analogue inputs can be switched to microphone with 12V Phantom power if needed.
The unit also Integrates an Ethernet Switch for daisy-chain connections. No external switch is needed.

WiFi and Bluetooth are available for direct wireless operation.
