Its compact dimensions (482mm width, 420mm depth, 88mm height) make it suitable for various installations.

## Long description

The AUDAC CAP448 audio amplifier is a professional 4.0-channel Class D unit designed for multi-zone audio distribution. Each channel delivers up to 480 W peak power, with balanced XLR inputs and link-through outputs for straightforward system expansion. The amplifier uses a switching power supply and Class D amplification to achieve high efficiency in a compact 19" 2U rack housing. Built-in protection against DC, short circuit, overload and overheating plus a temperature-controlled fan ensure stable operation in installed environments. Compact dimensions (482 mm x 420 mm x 88 mm) and a weight of 8.85 kg make it suitable for fixed installations and rack-mounted AV systems.
Advantages
The CAP448 provides four independent channels in a single 2U rack unit, reducing rack space while enabling flexible multi-zone audio distribution. Class D technology and a switching power supply deliver efficient power handling and reduced heat generation. Balanced XLR inputs and link output connectors simplify integration with professional audio sources and additional amplifiers. Built-in protection circuits and a temperature-controlled fan increase reliability by protecting the amplifier from DC faults, short circuits, overloads and overheating.
Suitable for
 Multi-zone background music systems in retail or hospitality
 Conference rooms and meeting facilities requiring multiple independent zones
 Small to medium fixed installation AV systems
 Distributed audio systems where rack-mount installation is preferred

How to use
Install the amplifier into a standard 19" rack using appropriate mounting screws and allow adequate ventilation around the unit. Connect balanced audio sources to each channel's XLR input and use the link outputs if daisy-chaining to other amplifiers. Wire loudspeakers to the terminal block outputs according to the system impedance and channel assignment. Adjust the gain control per channel to achieve the desired level and engage the 400 Hz high-pass filter where required to protect full-range loudspeakers from low-frequency overload. Power the unit from a correctly rated mains supply and monitor the front panel indicators for any protection events.
Usage recommendations
For reliable long-term operation, ensure the amplifier has sufficient ventilation and is not enclosed in a tightly sealed cabinet. Match speaker impedance and power handling per channel and avoid continuous operation at maximum output to prevent thermal stress. Use the high-pass filter for smaller loudspeakers and apply link outputs for distributing input signals across multiple amplifiers when building multi-zone systems.
