Product Overview
The JBL VMA Series VMA1120 is a cost-effective mixer/amplifier with low-impedance functionality (4Ω, 8Ω) and high-impedance 70V and 100V output. The VMA1120 is designed with convenient and flexible features to be used by commercial integrators worldwide, ideal for emerging markets. Features 5 inputs and a single 120W output with independent bass/treble controls. Works with all JBL CSR-V wall controllers, and offers paging chime and priority muting functionality. Rack-mounting hardware included.
