Audibax Pro MA4500T DSP - 19″ 4×300 W (2×600 W bridge) matrix amplifier with DSP and Ethernet control

Audibax Pro MA4500T DSP - 19″ 4×300 W (2×600 W bridge) matrix amplifier with DSP and Ethernet control

The Audibax Pro MA4500T DSP is a 4-channel Class D installation matrix amplifier with hybrid operation in low impedance (Low-Z) and 70/100 V lines. It incorporates DSP processing with control via Ethernet, USB, RS-232 and RS-485 , to configure equalization, dynamics and routing with precision and real-time monitoring. It delivers 300 W RMS per channel at 8 Ω and offers 2 × 600 W (LoZ / 100 V) bridge mode in a 19 "1U format ( 483 × 300 × 44.5 mm , 4.2 kg ). Professional connectivity with XLR and Euroblock simplifies integration into racks and technical panels, while the terminal outputs (Terminal) facilitate wiring to low impedance speakers or constant voltage lines.

Main features

• 4×300 W RMS at 8 Ω ; Low-Z/70V/100V operation; bridge 2×600 W (LoZ / 100 V).
• High-efficiency Class D stage with THD+N < 0.01% , crosstalk −70 dB and SNR > 94 dB .
• Integrated DSP with control via Ethernet / USB / RS-232 / RS-485 .
• Line/mic inputs (4 channels) with XLR and Euroblock connectors ; line outputs via XLR + Euroblock .
• Terminal power outputs for safe installation in low impedance or 70/100 V.
• Compact form factor : 1U / 19″ , 483 × 300 × 44.5 mm , 4.2 kg ; rack mountable.
• Wide power supply : AC 180–264 V, 50–60 Hz .
• Protections and alarm mode : limiter and peak detection.

Product benefits

• One stage for all : Works for both Low-Z speakers and 70/100V lines, reducing complexity and inventory.
• Consistent quality 24/7 : DSP and limiters maintain levels and minimize distortion during continuous use.
• Rapid deployment : XLR/Euroblock connectors and terminal outputs that speed up installation, inspections and maintenance.
• Centralized management : control via Ethernet or serial ports for remote adjustments and monitoring in multi-zone installations.

Use cases

• Retail and hospitality : ambient music by zones with long runs at 100 V.
• Education and corporate : auditoriums, lecture halls, and conference rooms with flexible routing and centralized control.
• Sports and leisure : large-area venues that require stability, security and remote monitoring.

Frequently Asked Questions
