Product information

Description

The Audac CAP424 is a 4.0-channel Class D audio amplifier designed for professional and installation use. Each of its four channels delivers up to 240 W output power (960 W peak per channel specification) and supports 100 V multi-zone distribution, making the CAP424 suitable for commercial audio systems, venues and AV installations. The unit uses a switching power supply and Class D amplification for high efficiency and reduced heat generation, and is built into a 2U, 19" rack housing with a compact footprint and a weight of 8.35 kg. Protected circuitry and a temperature-controlled fan provide stable operation in continuous use.

Advantages

The CAP424 combines multi-zone flexibility and a conservative control layout: balanced XLR inputs with link-through outputs, per-channel gain controls and a high-pass filter switch (400 Hz). Reliable terminal block speaker outputs and XLR connectivity simplify installation and wiring in fixed AV setups. The switching power supply and Class D design deliver efficient power conversion and lower thermal dissipation, while built-in protections guard against DC faults, short circuits, overload and overheating to maintain long-term reliability.

Suitable for

Multi-zone public address and background music systems in commercial spaces
Fixed installation in conference rooms, retail outlets and hospitality venues
AV racks in schools, offices and houses of worship requiring multiple amplified zones
Projects needing compact rack-mount amplifiers with per-channel controls and 100 V distribution

Key specifications

Amplifier class: Class D with switching power supply
Channels: 4 independent channels (4.0)
Output power: 240 W per channel nominal (960 W peak per channel specification)
Speaker outputs: 100 V line distribution via terminal block connectors

Per-channel controls: Gain potentiometer and 400 Hz high-pass filter switch
Protection features: Overheating, overload, short-circuit and DC fault protection; signal limiting
Cooling: Temperature-controlled fan
Power supply: 230–240 V, 50 Hz mains
Form factor: 19" rack, 2U height; product colour: black; weight: 8.35 kg

How to use

Mount the CAP424 into a standard 19" rack using the 2U front panel mounting points and ensure adequate ventilation around the chassis. Connect input sources to the balanced XLR inputs and, if required, link through to additional amplifiers using the provided link outputs. Set the per-channel gain controls to a conservative starting position and enable the 400 Hz high-pass filter where low-frequency content should be reduced. Wire loudspeakers to the 100 V terminal block outputs according to the installation plan, observing proper tap settings on transformer-equipped speakers. Power the unit from a 230–240 V AC mains supply and monitor operation; the temperature-controlled fan will regulate cooling during continuous use.

Usage recommendations

For reliable long-term operation, maintain clear airflow around the rack, avoid stacking heat-generating equipment directly above the amplifier, and perform speaker load verifications before leaving the system in service. Use balanced source cabling for best noise immunity in professional installations and set gain levels to prevent persistent limiting.
