Read all operating instructions before using this equipment.. To reduce the risk of electrical shock, do not open the unit. There are NO USER REPLACEABLE PARTS INSIDE. Please contact the Gemini Service Department or your authorized dealer to speak to a qualified Gemini Sound Products technician.. Be sure to allow adequate front and rear ventilation to avoid possible heat damage to your equipment.. Be sure that AC power is OFF and all level controls are set to MINIMUM before making connections. This will eliminate any chance of unexpected, loud audio transients that could damage your speaker systems. In the USA: If you experience problems with this unit, please call () -900 for Gemini Customer Service. Do not attempt to return this equipment to your dealer.. Be sure that AC power is OFF when changing modes of operation and when changing the position of the ground lift switch.. DO NOT EXPOSE THIS UNIT TO RAIN OR MOISTURE. Operators of electronic equipment should in no way be in contact with water.. When connecting to AC power line be sure you haven t lost the ground connection by using an adapter or extension cord without a prong plug.. DO NOT USE ANY SPRAY CLEANER OR LUBRICANT ON ANY CONTROLS OR SWITCHES. CONNECTION, CONTROLS AND INDICATORS Rear panel Input Section: /" Phone lnput Jacks (, ): accept a balanced as well as an unbalanced line level signal. The unbalanced line uses a standard tip-sleeve connection. The tip is positive and the sleeve is negative or ground. The balanced line uses a tip-ring-sleeve connection. Tip is hot or positive (+), ring is cold or negative (-), and sleeve is shield or ground. Operation Mode Switch (): switch is used to set the unit for Stereo mode, Parallel Mono mode or Mono Bridge mode. AC Power Section: Fuse (): replace fuse with those of proper type and rating. Ground Lift Switch () is used to lift the ground from the chassis, see the Ground Lift Switch Instructions for more detail. AC Inlet () is used to attach the power cord to the unit. AC line voltage switch () allows reconfiguring amplifier for either 0-0V or 0-0V AC lines. Output Section: Disconnect unit from the AC power source before making any connections. Pay close attention to polarity (shown on the back of the unit) when connecting your speakers. Connecting your speaker systems using the wrong polarity will not damage your speakers, but will impact the quality of the sound (lack of bass and incorrect stereo image). Speaker Outputs (,,): the speaker output connectors are -way binding posts that will accept a standard banana plug, spade lugs, or bare wire. Make sure that all the connections are clean when using bare wire connections. If any strands of wire from one connector touch the adjacent connector, the sound will distort, and your amplifier will overheat and go into protection mode. NOTE: Total speaker impedance must not be lower than Ohm per channel for Stereo and Parallel Mono modes, and Ohm for Mono Bridge mode. Front Panel Power Switch (9) : turns the unit on and off. Power LED (0): the power LED lights when the power is on. If the power LED does not light, refer to the troubleshooting guide. Signal LED (): the signal LEDs for each channel show when a signal is present. In Mono Bridge mode, both the channel LED and the channel LED will light in unison. Clip LED (): 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 occurs. The clip LED should not remain constantly on or flash repeatedly during operation. For clean sound reproduction, the clip LED 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 an 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 (): 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 LED 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 Page

4 functions. If one of these situations occurs, 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 Troubleshooting Guide. If the protect LED remains lit when resuming amplifier operation, do not use the amplifier and contact an authorized service technician. Level Controls (,): establish the input levels required for each channel. Only the Channel Level Control () works in Mono Bridge mode. OPERATION THE AMPLIFIER S POWER MUST BE TURNED OFF WHEN CHANGING MODES OF OPERATION. Stereo Operation The unit has two channels for stereo operation. Each channel provides a separate and discrete signal at the speaker outputs according to the signal received at the inputs. The following instructions are for applications with Ohm or Ohm speakers of matched power ratings.. With the power off, set the OPERATION MODE SWITCH () to the STEREO position.. With the power off, connect your input cables to the channel and inputs using the /" INPUT JACKS (, ) of each channel.. Connect the loudspeakers to the channel and channel SPEAKER OUTPUTS (,). THE TOTAL SPEAKER LOAD MUST BE AT LEAST OHMS PER CHANNEL. If you try to operate at a lower impedance, the amplifier will go into protection mode and stop operation until you correct the load conditions.. With the LEVEL CONTROLS (,) of both channels set to zero (fully counterclockwise), turn the POWER SWITCH (9) on. Apply a signal to the input of the amplifier. The level of the input signal should be as high as you will ever need it to be. This way, it will be as high above the amplifier s noise floor as possible, ensuring an excellent performance and signal to noise ratio. Adjust the LEVEL CONTROLS for each channel to achieve the desired maximum listening level. Note, when the clip LEDs light, there is distortion present in the amplifier s output section. If a clip LED remains on or flashes repeatedly, reduce the signal level by lowering the input level control for the channel that is clipping or reduce the level at the source. Parallel Mono Operation Follow these instructions for Parallel Mono Operation using a single input cable, and you will have the same monophonic signal on both the channel and the channel outputs. Each channel s output is controlled independently by that channel s level control.. With the power off, set the OPERATION MODE SWITCH () to the PARALLEL Mono position.. With the power off, connect your input cables to the channel input only using the / " INPUT JACK () of channel.. Connect the loudspeakers to the channel and channel SPEAKER OUTPUTS (, ). THE TOTAL SPEAKER LOAD MUST BE AT LEAST OHMS PER CHANNEL. If you try to operate at less than Ohms per channel, the amplifier will go into the protection mode and stop operation until you correct the load conditions.. With the LEVEL CONTROLS (,) set to zero (fully counterclockwise), switch the power on. Apply a signal to the input. The level of the input signal should be as high as you will ever need it to be. This way, it will be as high above the amplifier s noise floor as possible, ensuring an excellent performance and signal to noise ratio. Adjust the LEVEL CONTROLS for each channel to achieve the desired maximum listening level. Note, when the clip LEDs light, there is distortion present in the amplifier s output section. If a clip LED remains on or flashes repeatedly, reduce the signal level by lowering the input level control for the channel that is clipping or reduce the level at the source. Mono Bridge Operation Follow these instructions to bridge the unit s output. Bridging the amplifier converts the unit to a monophonic or single channel amplifier. The amplifier can be used with Ohm or higher loads only in Mono Bridge mode. This mode is used to provide a higher voltage with greater headroom to your speaker. Before setting your amplifier for Mono Bridge operation, make sure that your speaker can handle the high power level provided by the amplifier in Mono Bridge mode. CAUTION: VOLTAGE OVER 00 VOLTS MAY BE PRODUCED AT THE BRIDGE OUTPUT TERMINALS IN THIS MODE.. With the power off, set the OPERATION MODE SWITCH () to the BRIDGE position.. With the power off, connect your input cables to channel input only using the /" INPUT JACK () of channel.. Connect the loudspeaker to the BRIDGE SPEAKER OUTPUT () only. Be sure the polarity of your connection is correct. The total speaker load must be at least Ohms or above. If you try to operate at less than Ohms in the Mono Bridge mode, the amplifier will go into the protection mode and stop operation until you correct the load conditions.. With the CHANNEL LEVEL CONTROL () set to zero (fully counterclockwise), switch the power on. Apply a signal to the input. The level of the input signal should be as high as you will ever need it to be. This way, it will be as high above the amplifier s noise floor as possible, ensuring an excellent performance and signal to noise ratio. Adjust the LEVEL CONTROL () for channel to achieve the desired maximum listening level. Note, when the clip LEDs light, there is distortion present in the amplifier s output section. If a clip LED remains on or flashes repeatedly, reduce the signal level by lowering the input level control for channel or reduce the level at the source. During Mono Bridge operation, the channel level is inactive, however, both channels LEDs will flash simultaneously and show output conditions. Using the Ground Lift Switch Depending on your system configuration, sometimes applying the ground will create a quieter signal path. Sometimes lifting the ground can eliminate ground loops and hum to create a quieter signal path.. With the power amp on, listen to the system in idle mode (no signal present) with the ground applied (the GROUND LIFT SWITCH () in the left position).. Turn the power off before moving the GROUND LIFT SWITCH (). Lift the ground by moving the GROUND LIFT SWITCH to the right, turn the power back on and listen to determine which position will provide a signal free of background noise and hum. Keep the GROUND LIFT SWITCH in the ground position if the noise level remains the same in either position. CAUTION: DO NOT TERMINATE THE AC GROUND ON THE POWER AMPLIFIER IN ANY WAY. TERMINATION OF THE AC GROUND CAN BE HAZARDOUS. Page
