The JBL VMA Series of Mixer-Amplifiers are professional tools designed and built for Installed sound applications. There are both single channel and two channel models with five or eight mixer channels, respectively. They provide mixer capability with independent level control for each input channel and amplification with a choice of low impedance, 70V or 100V outputs. The product includes a rack mounting kit for installations to a cabinet. The system can be easily expanded with additional JBL Commercial Series Amplifiers and Commercial Series Mixers. Provisions are included for remote volume control using the JBL CSR-V control module.
