Product Description
The JBL VMA1120 is an outstanding mixer/amplifier from the cost - effective JBL VMA Series. It offers low - impedance functionality (4, 8) and high - impedance 70V and 100V output, making it a perfect choice for commercial integrators worldwide, especially in emerging markets. Key features include 5 inputs and 1 120 - watt output, independent bass and treble controls for each output channel, 100V and 70V output or 4/8 impedance options, paging chime, priority muting, compatibility with JBL CSR - V wall controllers, balanced mic/line inputs, and RCA (.775V) inputs. Rack mounting hardware is also included. Technical specs show great performance, such as a max output power of 120W into 4 or 8 at 1kHz with <= 0.5% THD, low insertion loss, and a wide range of input sensitivities and frequency responses.
Using the JBL VMA1120 is quite straightforward. First, connect your audio sources to the 5 inputs. You can use balanced mic/line inputs or RCA inputs according to your devices. Then, adjust the independent bass and treble controls on each output channel to get the sound you like. If you have a JBL CSR - V wall controller, you can use it to manage the device conveniently. For outputs, you can choose between 100V, 70V, or 4/8 impedance based on your needs. When using it, make sure the AC line voltage matches one of the nominal values (100V, 120V, 220V, 220 - 240V, 50/60 Hz). Keep the operating temperature between 0°C and 35°C at 95% R.H. (non - condensing). For storage, the temperature should be between - 20°C and 85°C. To maintain the device, keep it clean and dry. Regularly check the connections to ensure they are secure. If there are any issues, refer to the technical specifications for troubleshooting.
