- Page 5 “OFF” before any audio sources are switched off. By following this procedure it will prevent acoustic shocks to the speakers or potential damage to system components. After connecting all audio sources and powering on the mixer amplifier, adjust the level of each audio input to achieve the desired “mix”. Care should be taken to when adjusting microphone input volumes and the master volume, adjust both of these in small increment’s to avoid feedback (howl around). The goal is to achieve a clear balance between music and voice ensuring announcements can be clearly heard. DC power connection: The MA 120 features a 12V DC power input for operation from leisure type batteries or from battery DC backup sources. The amplifier should be connected to a fused, 12V DC source via the DC power input terminals (11) ensuring care is taken to observe the correct polarity. The amplifier will automatically transfer to DC operation should the main 240V input fail. The transfer is instantaneous and silent. Please note: The power on/off switch does not have any control over the 12V DC power input. 12V DC input – 4Ω 8Ω 16Ω 100V FUSE Battery DC 12V Master volume control: The master volume control affects the level of all audio sources within the amplifier. Turn the level control anti-clockwise to the lowest setting, or turn clockwise to adjust the overall output to the highest setting. Adjustments should be made gradually to avoid any sudden changes to the audio output. www.cleveracoustics.co.uk MA 120 Mixer Amplifier User Manual...
- Page 6 Tone control: The tone control can be used to adjust the overall sound from the amplifier. Turn anti-clockwise for more bass, or turn clockwise for more mid & treble. Microphone inputs: Two low impedance microphone inputs are provided, each located on the front panel via an unbalanced, 6.35mm (¼”) jack. Each microphone input features its own independent level control. Before connecting a microphone, turn the level control anti clockwise to the lowest setting. After connection, gradually increase the level control by turning clockwise until the desired level is achieved. Note: Unbalanced cable lengths should be kept to the minimum length possible, ideally under 20m and away from any potential sources of interference including power, speaker and control cables/equipment. Unbalanced microphone Single pole phone plug Line inputs: The amplifier features two audio inputs located on the rear panel, each input features a mono RCA (phono) input connector. The line inputs are designed for line level sources (150mV) such as CD players or MP3 players. A “Y” cable may be required to combine Left and Right outputs from stereo sources. Note: Only one of the two inputs may be used at any one time, the selector switch may be used to choose from the two inputs. Slide the switch to the left to select LINE 2 or slide to the right to LINE 1. Selector switch LINE 1 150mV 150mV LINE 2 LINE 1 LINE 2 Output connections: The amplifier may be used to drive either low impedance (4/8/16Ω) loads or 100V line constant voltage loads, only one output may be used, the amplifier is not designed to drive multiple loads simultaneously. www.cleveracoustics.co.uk MA 120 Mixer Amplifier User Manual...

Connect the 100V line level loudspeakers using a parallel wiring configuration taking care to ensure the load connected to the amplifier is within 85% of the amplifiers rated wattage to leave appropriate headroom. Care should be taken to check the wiring and load for short circuits before connecting the cable to the COM and 100V terminals on the rear panel.
