SERVICE MANUAL XPM-600 XPM-900 XPM-1200 Gemini Sound Products Corp. 120 Clover Place, Edison, NJ 08818 Tel (732) 738-9003 Fax (732) 738-9006 Page 1 6 7 1 2 3 4 5 8 9 10 11 6 7 9 10 11 1 2 3 4 5 8 12 13 14 15 16 17 14 15 16 18 19 20 Stereo Parallel Mono Mono Bridge Connections, Controls and Indicators Rear Panel Note: 120V and 230V units have different types of output connectors on the rear panel. Input Section: There are two parallel input connectors (one female XLR and one 1/4" jack) per channel. Either can be used as an input or as a link to chain amplifiers. XLR Input Jacks (1, 5): electronically balanced inputs accept a standard XLR male connector. Pin 1 = shield/ground, pin 2 = hot or positive (+) and pin 3 = cold or negative (-). 1/4" Phone Input Jacks (2, 4): accept a balanced as well as an unbalanced line level signal. The unbalanced line uses a standard tipsleeve connection. The tip is positive and the sleeve is negative/ ground. The balanced line uses a tip-ring-sleeve connection. Tip = hot or positive (+), ring = cold or negative (-), and sleeve = shield/ ground. Operation Mode Switch (3): switch is used to set the unit for Stereo mode, Parallel Mono mode or Mono Bridge mode. Clip LED (15): the amplifier has true clip LEDs to help you properly control the amplifier's output and achieve undistorted sound. The clip LEDs for each channel light when your signal level is so strong that the distortion reaches 1% THD. The clip LED should not remain constantly on or flash repeatedly during operation. For clean sound reproduction, the clip should only light occasionally for an instant. If the LED remains on or flashes repeatedly, you will hear distorted sound that can be damaging to your speaker systems. If this occurs, reduce the signal level by lowering the input level control for the channel that is clipping or reduce the level at the source. If the clip LED lights when no signal is present, it may indicate a RF signal on the output which may cause damage to speakers (the RF signal will not be audible). Please note that when you are using the amplifier in the Mono Bridge mode, both clip LEDs of the bridged channels will operate simultaneously. Protect LED (16): when you first turn on the amplifier, the protect LEDs light briefly during a turn-on delay which indicates that the outputs are disconnected internally. There will be an audible click when the outputs reconnect and the protect LEDs will turn off. Otherwise, the protect LED indicates that there is a problem either in the amplifier's external connections, load or temperature conditions or its internal functions. If one of these situations occur, the amplifier senses the problem and automatically switches into protection mode. The LED will light to warn you of the trouble and the amplifier will stop working. If this occurs, switch off the amplifier and refer to the Trouble Shooting Guide. If the protect LED remains lit when resuming amplifier ope
