The mixer/amplifier models include both single-channel and two-channel variants with four or eight mixer channels, allowing flexible audio management. The intuitive front panel features dedicated volume controls for each channel, a master volume knob, adjustable bass and treble controls, and a power switch, all illuminated for visibility in low-light conditions. It supports 8Ω and 4Ω speaker loads and is compatible with 70V and 100V distributed audio systems without additional transformers, providing versatile deployment options.

Connectivity is extensive, with balanced mic/line inputs, unbalanced RCA inputs, speaker outputs, and RJ45 connectors for integration with JBL CSR-V in-wall volume controls. The universal power supply accepts AC voltages from 100 to 240V at 50/60Hz. Environmentally conscious manufacturing under HARMAN’s GreenEdge™ initiative ensures lead-free RoHS compliance and efficient use of recycled materials, while the DriveCore design enhances energy efficiency by up to 80 percent compared to previous models.
