JBL Professional VMA 260/2120

큰 이미지

The JBL VMA Series is a cost-effective line of Mixer/Amplifiers with low impedance functionality (4Ω, 8Ω) and high impedance 70V and 100V output. They are designed with convenient and flexible features to be used by commercial integrators worldwide, ideal for emerging markets.

특징

• 8 inputs with 2 outputs of 60 or 120-watts of power
• Independent bass and treble controls for each output channel
• 100V and 70V output, or 4Ω/8Ω
• Paging Chime, and Priority muting
• Works with JBL CSR-V wall controllers
• Balanced mic/line inputs; RCA (.775V) inputs
• Rack mounting hardware included
