Electro-Voice PA4150L Four-Channel 150 W Install Amplifier

The PA4150L puts four 150 W low-impedance channels in 2 RU, which is the practical answer when a job has four small zones and no room for four amplifiers. Pairs of channels bridge for two 315 W outputs into 8 ohms when two of those zones turn out to need more.

Each channel gets its own stepped rear-panel attenuator and a selectable 50 Hz or 300 Hz high-pass. Connections are Phoenix-type, protection covers thermal, peak limiting and turn-on delay, and three-stage front-to-rear fans keep four channels' worth of heat moving through a closed rack.
