Page 5: Operating Instructions
Mains voltage supply: Before connecting the amplifier to the local mains voltage outlet should be checked to ensure the available supply is 240V~AC 50Hz. This product is CLASS1 and requires a protective mains earth to be connected at all times. DO NOT remove or disconnect the earth. Power on/off procedure: After connecting your amplifier to the mains, turn all controls counter clockwise to the “0” position. Turn on audio sources (MP3 players, CD players, microphones etc) before powering the amplifier “ON”. The last product to be switched on is the amplifier. If you wish to power off the system, turn the amplifier’s master volume control counter clockwise to the “0” position before switching the amplifier “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. 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. Tone control: The tone control can be used to adjust the overall sound from the amplifier. Each of the three controls adjust a different frequency band. Turn anti-clockwise to increase, or turn clockwise to decrease the selected frequency band. Ground connection: The ground connection can be used for vinyl turntable sources with external earth connections. www.cleveracoustics.co.uk MA 135 Mixer Amplifier User Manual... - Page 6 Unbalanced microphone Single pole phone plug Priority control terminals (Music Mute): The MA 135 amplifier features a priority feature for microphone 1. When the Priority contacts are shorted, the amplifier will mute all other inputs while microphone 1 will remain active. Priority – 4Ω 8Ω 16Ω 100V Line inputs: The amplifier features two audio inputs located on the rear panel, each input features a pair of RCA (phono) input connectors configured in stereo. The LINE 1 input is designed for line level sources (150mV) such as CD players or MP3 players. The LINE 2 input is designed for RIAA level sources such as Turntables. 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 1 or slide to the right to LINE 2.

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.
