Audison Voce AV quattro - 4-Channel Amplifier with Hi-Res Bandwidth and Flexible Configuration

The Audison Voce AV quattro is an AB-class 4-channel amplifier that can be operated freely as a 4-, 3- or 2-channel amplifier. Thanks to AMP (Amplifier Management Processor), the amplifier runs stably in continuous operation, while ART takes care of automatic power on and off. With its Hi-Res capable bandwidth of 4 Hz to 60 kHz and precise 24 dB/oct. filters, your system can be finely tuned – from the front system to the subwoofer.

Technical Highlights

• AB class for dynamic, detailed sound
• Operating modes: 4-, 3- or 2-channel
• Hi-Res Audio thanks to 4 Hz – 60 kHz bandwidth (-3 dB)
• AMP: Stable, safe operation under load
• ART: Auto Remote On/Off (via BTL speaker output, switchable)
• Integrated 12/24 dB/oct. filters including bass boost and subsonic
• Hi-level and Low-level inputs for OEM integration

Installation & Compatibility

The AV quattro can be integrated into both factory systems (via Hi-Level) and aftermarket systems. With the flexible filters, you can configure front/rear setups or a front-plus-sub scenario. ART eliminates the need for a separate remote signal in many vehicles. When installing, ensure adequate ventilation – AB-class delivers sound quality but generates waste heat under load.
