ArtSound PRL-3002 2-Channel Class D Power Amplifier

ArtSound PRL-3002 2-Channel Class D Power Amplifier – 600 W in a Single Rack Unit

The ArtSound PRL-3002 is a two-channel power amplifier from the Belgian installation brand ArtSound, delivering 2 x 300 watts into 8 ohm loads from a Class D design that fits in a single 19-inch rack unit. It is a pure power stage: feed it a line-level signal from a mixer, matrix processor, streamer or preamplifier, connect passive loudspeakers, and it supplies the muscle of an installed sound system in a restaurant, retail space, school, office or place of worship without taking up rack space the project does not have.

Class D amplification is what makes that density possible. The amplifier stages run efficiently and cool compared with traditional designs of similar output, which matters in equipment racks that hold several amplifiers and sources in a closed cabinet, running from opening to closing time. The published frequency range of 10 Hz to 30 kHz comfortably covers the full audio band the connected speakers will be asked to reproduce.

Key features

• Two channels rated at 2 x 300 W into 8 ohm loads
• Class D design in a 19-inch, 1U rackmount chassis
• Combo XLR and jack inputs for balanced or unbalanced sources
• Euroblock and speakON speaker outputs on the same amplifier
• Signal and clip or protection indicators for level setting and fault finding
• Overvoltage, short-circuit and thermal protection
• Universal 100 to 240 V AC mains input, 50 to 60 Hz
• Compact 275 mm depth that fits shallow installation racks

Connections for installers

Inputs are combo XLR and jack sockets, accepting balanced lines from professional processors just as easily as unbalanced feeds from simpler sources. On the output side, the choice of Euroblock connectors and speakON sockets covers both installation habits: Euroblock terminations suit fixed wiring looms landed once and left alone, while speakON gives a locking, touch-safe connector for systems that are reconfigured or serviced more often. Front-panel signal and protection indicators let a technician see at a glance whether a channel is receiving signal, running into clipping or has shut down protectively, which shortens fault-finding in a live venue considerably.

Protection and daily operation

Installed amplifiers fail in predictable ways: a shorted speaker cable, a blocked vent, a mains surge. The PRL-3002 protects itself against overvoltage, short circuits and overheating, so a wiring fault during a refit or a hot rack in summer should end with an indicator light rather than a repair bill. With no source selection, streaming or mixing functions of its own, the amplifier asks for nothing in daily use; the system in front of it handles control, and it simply needs ventilation space respected in the rack and speaker loads kept within its published ratings.

Planning a system around it

Match the PRL-3002 to passive speakers whose impedance and power handling suit a 300 watt per channel amplifier at 8 ohms, and confirm parallel speaker combinations against the amplifier’s documented load limits before wiring them. Used that way, one unit drives a stereo pair of main speakers, or two separately fed zones at the same level, in the background and foreground music systems ArtSound builds its range around: compact, racked and forgotten about while it works.
