TO PREVENT ELECTROMAGNETIC INTERFERENCE WITH ELECTRIC APPLIANCES SUCH AS RADIOS AND TELEVISIONS, USE SHIELDED CABLES AND CONNECTORS FOR CONNECTIONS. THE EXCLAMATION POINT WITHIN AN EQUILATERAL TRIANGLE IS INTENDED TO ALERT THE USER TO THE PRESENCE OF IMPORTANT OPERATING AND MAINTENANCE (SERVICING) INSTRUCTIONS IN THE LITERATURE ACCOMPANYING THE APPLIANCE. THE LIGHTNING FLASH WITH ARROWHEAD SYMBOL, WITHIN AN EQUILATERAL TRIANGLE, IS INTENDED TO ALERT THE USER TO THE PRESENCE OF UNINSULATED "DANGEROUS VOLTAGE" WITHIN THE PRODUCT'S ENCLOSURE THAT MAY BE OF SUFFICIENT MAGNITUDE TO CONSTITUTE A RISK OF ELECTRIC SHOCK TO PERSONS. POWER-CORD PROTECTION: Power-supply cords should be routed so that they are not likely to be walked on or pinched by items placed upon or against them, paying particular attention to cords at plugs, convenience receptacles, and the point where they exit from the product. OUTDOOR ANTENNA GROUNDING: If an outside antenna or cable system is connected to the product, be sure the antenna or cable system is grounded so as to provide some protection against voltage surges and built-up static charges. Article 810 of the National Electrical Code, ANSI/NFPA 70, provides information with regard to proper grounding of the mast and supporting structure, grounding of the lead-in wire to an antenna discharge unit, size of grounding conductors, location of antenna-discharge unit, connection to grounding electrodes, and requirements for the grounding electrode. See Figure B. LIGHTNING: For added protection for this product during a lightning storm, or when it is left unattended and unused for long periods of time, unplug it from the wall outlet and disconnect the antenna or cable system. This will prevent damage to the product due to lightning and power-line surges. POWER LINES: An outside antenna system should not be located in the vicinity of overhead power lines or other electric light or power circuits, or where it can fall into such power lines or circuits. When installing an outside antenna system, extreme care should be taken to keep from touching such power lines or circuits as contact with them might be fatal.

(2) p-07 (3) INTRODUCTION: Congratulations on purchasing your Gemini Power Amplifier. This state of-the-art power arnplifier includes the latest features and is backed by a three year limited warranty. Prior to use, we suggest that you carefully read all the instructions. FRONT PANEL: POWER SWITCH: POWER SWITCH (7) turns the unit on and off. POWER LED: The POWER LED (8) lights when the power is on. If the POWER LED (8) does not light, refer to the trouble-shooting guide. LEVEL CONTROLS: LEVEL CONTROLS (9) control the input levels for each channel. VU METERS: Large blue-light illuminated VU METERS (10) display the output level of each channel. FEATURES: · · · · · · · · · State-of-the-art circuitry for the finest sound quality and reliability Protection Circuitry (short circuit, thermal cutoff, sub/ultrasonic frequency filters, turn-on delay, main fuse, secondary fuses) Unbalanced stereo inputs with RCA type jacks Signal ground lift switch eliminates hum from connection loops Large blue-light illuminated VU meters to give you greater control Ultra-modern design with professional 19" rack mounts Front-to-rear airflow with variable speed fan control for maximum cooling and quietest possible operation Compact 2U well balanced enclosure Steel reinforced chassis construction for durability and longevity OPERATION: STEREO OPERATION: The unit has two channels for stereo operation. Each channel provides a separate signal at the speaker outputs. The following instructions are for use with 4 or 8 speakers of matched power ratings. 1. With the power OFF, connect your input cables to the CHANNEL A and CHANNEL B inputs using the RCA INPUT JACKS (5) 2. Connect your speakers to the CHANNEL A and CHANNEL B SPEAKER OUTPUTS (6). THE TOTAL SPEAKER LOAD MUST BE AT LEAST 4 PER CHANNEL. 3. With the LEVEL CONTROLS (9) of both channels set to zero (fully counterclockwise), turn the POWER SWITCH (8) ON. With the level controls of your MIXER or other INPUT device turned all the way DOWN, turn the amplifier level controls all the way up for desired loudness from your speakers. 4. Now adjust your MIXER or other INPUT source to your desired listening level. You also have the choice of keeping the volume of both speakers equal, or for certain situations you can adjust the volume so one side will be louder than the other. CAUTIONS: 1. Read all operating instructions before using this equipment. 2. To reduce the risk of electrical shock, do not open the unit. There are NO USER REPLACEABLE PARTS INSIDE. Please contact the Gemini Customer Service Department or your authorized dealer to speak to a qualified Gemini Sound Products technician. 3. Be sure to allow adequate front and rear ventilation to avoid possible heat damage to your equipment. 4. 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 1 (732) 738-9003 FOR GEMINI CUSTOMER SERVICE. DO NOT ATTEMPT TO RETURN THIS EQUIPMENT TO YOUR DEALER. 5. Be sure that AC power is OFF when changing modes of operation and when changing the position of the Ground Lift Switch. 6. DO NOT EXPOSE THIS UNIT TO RAIN OR MOISTURE.

When connecting to AC power line be sure you haven't lost the ground connection by using an adapter or extension cord without a 3 prong plug. 8. DO NOT USE ANY SPRAY CLEANER OR LUBRICANT ON ANY CONTROLS OR SWITCHES. USING THE GROUND LIFT SWITCH: Depending on how your sound system is hooked up, sometimes applying the ground will create a quieter signal path. Sometimes lifting the ground can eliminate ground loops and that annoying hum to give you quieter and cleaner overall sound. 1. With the power amp ON, listen to the system in idle mode (no music or signal) with the ground ON. The GROUND LIFT SWITCH (4) will be in the left position. 2. Turn the power OFF before moving the GROUND LIFT SWITCH (4). Now lift the ground by moving the GROUND LIFT SWITCH to the right. Turn the power back ON and listen to determine which position makes the overall s ...
