  • Page 4: Safety First

    MIXING AMPLIFIERS Safety First ! • Caution: This professional device needs to be installed by qualified personnel only. • Caution: speaker and power wires must be compliant with your local low Voltage directive. • Please check the carton box for any kind of damage on reception of the goods.
  • Page 5 MA35 & MA65 Instruction manual • Always operate the unit with the AC ground wire connected to the electrical system ground. • Set level controls on amplifiers all the way down during power- up to prevent speaker damage if there are high signal levels at the inputs.
  • Page 6 Stereo line inputs are internally mixed to mono. Alternatively, you can connect your mono sources to the left or right rca line in. MA35/65 have mains power and emergency power connectors. MA35 can be emergency powered from 12VDC power sources such as car batteries.
  • Page 7 MA35 & MA65 Instruction manual Operation 1. Power switch: flip the switch to turn the mains power on and off. This switch has no influence on the emergency power supply. 2. Power/status indicator: the led lights up green when mains or emergency power is present.
  • Page 8 MIXING AMPLIFIERS Since this is a mixing amplifier, the inputs are all mixed together, the output level of each input is determined by the position of these controls. The controls of inputs not in use should be set to the 0 position to avoid excessive noise. 6.
  • Page 9 If hum occurs, use a ground loop isolator instead. 4. Emergency power supply connector: connect the emergency DC supply here. 12 VDC for MA35, 24 VDC for MA65. Please note that the output level may vary up to 3 dB when the emergency supply is in use.
  • Page 10 MIXING AMPLIFIERS 35 Watts (MA35) or 65 Watts (MA65). In 100 Volt this results in a minimum load impedance of 286 Ohms (MA35) or 154 Ohms (MA65). The low impedance output (8 Ohms) requires a load of 8 to 16 Ohms. Never use more than one output simultaneously.
  • Page 11 MA35 & MA65 Instruction manual 11. Microphone 3 input on XLR: balanced microphone level input with optional phantom power supply. This input is internally hardwired to the MIC 3 TRS jack input (12) and to line input 3 (10). Use only one of these inputs at the time. Do not connect...
  • Page 12 MIXING AMPLIFIERS inputs at the time. Do not connect an unbalanced signal to the XLR connector when phantom power is present, this will result in a short circuit of the phantom power supply. 16. Microphone 1 input on DIN5: balanced microphone level input.
  • Page 13 MA35: 6.3A quick acting, for MA65: 8A quick acting. This fuse offers additional protection for the emergency power supply and the internal power supply. Replace only with the same type of fuse: 6.35 x 30 mm, F6.3AF/250V for MA35 or F8AF/250V for MA65. 2. Phantom power on/off jumper:...
  • Page 14 MIXING AMPLIFIERS this jumper in the OFF position. When you set this jumper to the ON position, voice activated muting (vox) will be available on microphone input 1. This muting system overrides the mute activated by the chime/mute contacts. This way a two level priority system is available.
  • Page 15 To measure the total load a chain of 100 Volt speakers represents, you need a dedicated impedance meter such as the Apart IMPMET. Measuring speaker impedance is not possible with a standard multi-meter because an ohmmeter measures resistance, using a DC Voltage or something similar.
  • Page 16 MIXING AMPLIFIERS The Apart IMPMET is a dedicated speaker impedance meter.
