Product information

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

Key specifications

  • Amplification type: Class D
  • Channels: 4 independent channels
  • Peak output per channel: 480 W
  • Inputs: Balanced XLR per channel with link-through outputs
  • Output connections: Terminal block connectors for reliable wiring
  • Control: Individual gain potentiometer and 400 Hz high-pass filter switch per channel
  • Protection: DC detection, short circuit, overload protection, thermal protection and signal limiting
  • Cooling: Temperature-controlled fan
  • Enclosure: 19" rack-mount, 2U (88 mm) height, durable metal housing
  • Dimensions (W x D x H): 482 x 420 x 88 mm
  • Weight: 8.85 kg
  • Color: Black

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.

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%.
