Installing Rack Mount Ears
If you are planning on installing this amplifier into a rack continue reading how to install the supplied rack ears.

  1. Use the supplied three screws to attach the supplied rack ears to the SAM500 amp. If required, the feet on the bottom of the amplifier can also be removed at this time by unscrewing the mounting screws located in the center of each foot.
  2. Due to the weight of the amplifier, it is recommended that rear supports be secured to the rear rack rails. Hardware to do this is not supplied with the amplifier and is specific to the type and depth of rack being used.

NOTE: Leave adequate ventilation above and below the amplifier when rack mounted. If there is not enough ventilation, amp may over heat and switch to standby mode.

To change the operating line voltage, turn the power off using the power button and unplug the power cord. Remove the plastic cover screws and the plastic cover over the voltage selector ocated on the rear of the amp. Set the switch to the correct position for the line voltage in your country. Replace the plastic cOver and screws over the voltage selector switch.
    NOTE: If required, remove the IEC line cord and replace with an IEC AC cable that matches the AC wall socket, this should be a 1OA rated cable. When the voltage selector switch is changed, the fuse must also be changed to continue to provide protection to the amplifier.
