    GM SERIES USER MANUAL 3. Interface Elements. (1) Power Switch This switch controls the power supply to the amplifier. There is a short delay on power-up, this is to avoid switch-on "thump" which could damage the loudspeakers. (2) Gain Control The Output level is adjusted by this control.
  • Page 6 GM SERIES USER MANUAL (4) Cooling Fan Outlet Hot air exits here. M ake sure all ventilation paths & slots are free from obstruction and air flows freely, otherwise the amplifier will trip into thermal protect mode prematurely and in some extreme circumstances damage may occur.

  • Page 7: Recommended Usage

    The red wire from the GM50 is the positive (+) feed and the black wire is the negative (-) feed. The simplest method of connecting is to attach the red wire to the positive speaker terminal and the black wire to the negative speaker terminal or in the case of systems featuring a crossover network, connecting the corresponding wires to the correct terminals on the crossover.
  • Page 8 Wiring your speakers in parallel like this will give you the following impedances: 2 x 4 ohm speakers = 2 ohm load (Not Suitable) 2 x 8 ohm speakers = 4 ohm load 2 x 16 ohm speakers = 8 ohm load You may also use a combination of different value Speakers as long as their total is no less than 4 ohm...
  • Page 9 Using this series/parallel wiring, the total impedance of your cabinet will be the same as an individual speaker (only if all speakers are the same impedance). So if you are using x4 4 ohm speakers, the cabinet will be 4 ohms. If using x4 8 ohm speakers, the cabinet will be 8 ohms, etc.
