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
  • Inputs: Balanced XLR connectors with link-through outputs
  • 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.

Amplifier class: An electronic amplifier, amplifier, or (informally) amp is an electronic device that increases the power of a signal. It does this by taking energy from a power supply and controlling the output to match the input signal shape but with a larger amplitude. Power amplifier circuits (output stages) are classified as A, B, A/B and C for analog designs, and class D and E for switching designs based on the proportion of each input cycle (conduction angle), during which an amplifying device is passing current.

Total Harmonic Distortion (THD): Total harmonic distortion is a measure of non-linear harmonic distortion and is given in %. Non-linear harmonic distortions are signals which were not present in the original before the signal was converted by the headphones. These unwanted signals are caused by the diaphragm, whose movements do not precisely move in time with the electric signals that cause it to move. Unfortunately, this is a feature of all electroacoustic transducers. Although it cannot be completely eliminated, suitable steps can be taken to minimise it. However, the user is not interested in why this distortion takes place but in how great the level of distortion must be for it to become perceptible. According to the findings of several research projects, a total harmonic distortion of 1% in the frequency range of 100 to 2000 Hz is imperceptible. Below 100 Hz, the perceptibility threshold lies at 10%.
