## Long description

The AUDAC EPA254 is a Class D audio amplifier with 4.0 output channels and a low Total Harmonic Distortion of 0.1%. Designed for compact installations, this black amplifier operates on 230–240 V AC at 50–60 Hz and has a typical power consumption of 438 W. The unit is passively cooled, single rack space sized and weighs 4.7 kg, making it suitable for both fixed and mobile audio systems. It includes balanced XLR inputs with XLR link-through outputs and terminal block speaker outputs, and features an integrated active crossover network for flexible stereo and bass cabinet configurations.
Advantages
The EPA254 combines Class D efficiency with a quad-channel layout that can be configured as two independent stereos or as a four-channel setup, delivering clear audio with minimal heat generation due to its passive cooling. Automatic standby reduces power draw to less than 1 W when no audio is present, improving energy efficiency. Built-in protection circuitry guards against DC faults, short circuits, overheating and overload, increasing operational reliability in professional AV environments.
Suitable for
 Small to medium fixed installation audio systems
 Mobile PA and rental setups requiring compact amplifiers
 Stereo systems paired with a bass cabinet using the integrated crossover
 Multi-zone applications where two independent stereo outputs are needed

How to use
Install the EPA254 in a single rack space using appropriate mounting hardware and ensure adequate ventilation despite passive cooling. Connect audio sources to the balanced XLR inputs and, if required, use the XLR outputs for signal link-through to additional units. Wire speaker outputs to the terminal block connectors following polarity markings. Configure the integrated crossover and channel grouping according to the speaker system: set up two independent stereo pairs or a four-channel layout as required. Power the unit from a 230–240 V, 50–60 Hz supply and allow a brief warm-up period for stable operation.
Usage recommendations
For reliable long-term operation, use proper speaker impedance matching and avoid sustained clipping to reduce stress on the amplifier. Keep the amplifier in a ventilated rack space and check cable terminations regularly. When integrating with bass cabinets, use the active crossover to assign low-frequency duties correctly and set levels conservatively during system tuning to prevent overload and ensure protection circuits operate only when needed.
