VMA 160/1120/1240
The JBL VMA series is a low-cost mixer/amplifier family with low impedance (4Ω, 8Ω) and high impedance 70V and 100V outputs. Designed for convenience and flexibility, they are designed for use by commercial integrators around the world and are ideal for emerging markets.
Features:
• 5 inputs, 1 outputs 60,120 or 240 watts of power
• Independent bass and treble control for each output channel
• 100V and 70V output or 4Ω/8Ω
• Page doorbell and priority mute
• with JBL CSR- V wall controller
• Balanced microphone/line input; RCA (.775V) input
• Includes rack mount hardware
