SAFETY
CAUTION: RISK OF ELECTRIC SHOCK, DO NOT OPEN 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 electrical shock to persons. 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.
WARNING:TO REDUCE THE RISK OF FIRE OR ELECTRICAL SHOCK, DO NOT EXPOSE THIS APPLIANCE TO RAIN OR MOISTURE. CAUTIONS: To prevent electrical shock, do not use this (polarized) plug with an extension cord, receptacle or other outlet unless the blades can be fully inserted to prevent blade exposure. ATTENTIONS : Pour preevenir les chocs electriques ne pas utiliser cette fiche polarisee avec un prolongateur, une prise de courant ou une autre sortie de courant, sauf si les lames peuvent etre inserees a fond sans en laisser aucune partiie a decouvert.
FOR YOUR SAFETY PLEASE READ! THANK YOU! Please read all the safety and operation instructions in manual before operation. Keep this manual for future reference. Also, keep the carton and packing material in case the unit needs to be returned for service. Avoid water, moisture, and heat. Power sources should be as described in the manual and/or marked on the chassis. Exercise caution to avoid situations where power supply cords may be walked upon or pinched. Please exercise reasonable caution; do not drop objects onto your unit or spill liquid into it.
SERVICING Users should not attempt to service beyond those means described in this manual. All other servicing should be referred to an authorized service agent. Typical situations requiring service Obvious mechanical damage from rough handling Liquid has spilled on or into the unit. Exposure to rain. Unit does not appear to operate normally.

SPEAKER CONNECTIONS
BEFORE CONNECTION Connect all inputs and outputs before turning power on. This device is capable of very high audio output levels. Making connections with power up can cause loudspeaker damage. This is a full stereo system, be sure left and right inputs on stereo inputs are connected accordingly for proper stereo reproduction and accurate panning of signal. Be certain that all connectors are clean and firmly connected. Loose or dirty connections generate excessive noise and distortion and may generate popping noise that can damage loudspeakers.
Strip each wire back evenly, about 3/8-inch for connection. The amount of exposed wire must be minimal because significant power levels are present.
Each channel will accept one 4ohm speaker or two 8-ohm speakers.
Additional speakers could cause thermal protective shut down of the amplifiers.

FRONT PANEL CONTROLS CH1~CH6 1. HIGH: Shelving type tone control adjusts channel frequencies above 10KHz ±15dB. 2. MID: Peaking type tone control adjusts channel frequencies centered around 1KHz ±15dB. 3. LOW: Shelving type tone control adjusts channel frequencies below 60KHz ±15dB. 4. EFF: Sends channel signal to on-board digital reverb effect and external effects patch for use of external effect device. 5. MON: Monitor volume control for mixing monitor output to patch panel for feed to external monitor amplifier. 6. PAN: This control positions the channel signal from left to right for stereo imaging. 7. VOL: Channel volume control mix to master. 8. PEAK LED: Illuminates with excessive input signal level. Excessive signal results in significant audible distortion. 9. GAIN ATTENUATION SWITCH(-20dB): "In", when peak LED flashes, reduces input level which reduces the distortion that results from excessive input level. 10. MIC INPUT JACK: 1/4" unbalanced 11. XLR BALANCED LO-Z MIC INPUT JACK (Pin-1, gnd; Pin-2, high; Pin-3, low)
CH7/8~CH9/10 12. HIGH: Shelving type tone control adjusts channel frequencies above 10KHz +15dB. 13. MID: Peaking type tone control adjusts channel frequencies centered at 1KHz +15dB. 14. LOW: Shelving type tone control adjusts channel frequencies below 60KHz +15dB. 15. MON: Monitor mix level adjustments to adjust volume of individual input to monitor master output. 16. BAL: Balancing left & right volume control of stereo channel. 17. VOL: Channel volume control mix to master. 18. PEAK LED: Illuminates with excessive input signal level. Excessive signal results in significant audible distortion. 19. SSS (Spectral Surround Sound): When selected this switch routes stereo signals through a proprietary digital spectral surround sound processor for enhanced surround stereo presence. This is not part of the effects processor system. 20. 1/4" STEREO INPUT JACK: -10dB (300mV)music source. 21. RCA-TYPE STEREO INPUT JACK : Stereo input jack for music source of 20dB.
22. DLY: Echo time delay control. 23. RPT: Repeat echo control. 24. HIGH: High tone control of effect. 25. LOW: Low tone control of effect. 26. MON: Effect to monitor mix volume control. 27. VOL: Channel volume control of effects mix to master. 28. SELECTOR: Selects between stereo or mono. 29. EFF/RTN: External echo return volume control. This controls effects return volume when external device is used.

FRONT PANEL CONTROLS
30. LEVEL LED: Displays output levels of L-ch, R-ch and Monitor. Reduce appropriate master volume control if system is operating in red zone. Excessive output levels result in excessive distortion and risk of loudspeaker damage 31. POWER: Power on/off switch. 32. PHANTOM POWER: Connects +48V equally to pins 2 and 3 of each mic input XLR connector to provide power to condenser microphones, where applicable. Yellow LED indicates when phantom power is on. Condenser mics and dynamic mics may normally be used at the same time without damage but to avoid possible problems, switch phantom power on only when condenser microphones are being used. 33. PHANTOM POWER ON: When illuminated. 34. PROTECTION: Protection circuit indicator. LED lights when unit has shut down to protect itself from damage as a result of overheating which is generally caused by output short or DC voltage. Be certain to correct the problem before turning system back on or damage may result. Check ventilation, speaker wiring and speaker load. Speaker load should not be be less than 4 ohms, loads less than 2 ohms will cause the protection circuit to operate. 35.EXTERNALEFFECT RETURN- VOLUME CONTROL. 36. STEREO 7-BAND GRAPHIC EQUALIZER: Adjusts tonal quality of amplifier output. 37. MASTER-VOLUME: Stereo output volume control. 38. MASTER-MONITOR: Volume control for send to external monitor amplifier. 39. TAPE-VOLUME: Input level of tape/CD input connection on rear panel. 40. TAPE-MONITOR: Adjusts level from tape/CD in on back panel to monitor mix for playback of Tape/CD signal to monitors for sing-along with music source monitor.

REAR PANEL CONTROLS
1. EFFECT SEND/RETURN: 1/4" TRS (Tip-Ring-Sleeve) insert-type connection. Patches (inserts) external effect (compressor, processor etc) or graphic EQ between mixer and power amplifier sections. See diagram for connection.. 2. EXTERNAL ECHO RETURN: Unbalanced 1/4" phone jack, stereo return from external effect device. 3. EXTERNAL ECHO SEND: Unbalanced 1/4 " phone jack sends signal to external effect device from "EFF" mix. Using this output disconnects the internal effects. 4. MONITOR OUTPUT: 1/4" phone jack send from "MON" mix to external monitor amplifier. 5. TAPE RECORD: RCA-Type jacks send pre-master fade output to external recorder.
6. TAPE PLAY: RCA-Type inputs for signal from external music source such as cassette player, CD player, keyboard or drums. If source is a cassette recorder, output and record in should not be connected at the same time. 7. LINE OUTPUT: 1/4" phone patch to external amplifier(s) for additional power. 8. FUSE: Holder with 125V 10A FUSE 9. GROUND: If other devices are not grounded as the SE unit is, grounds must be connected here. To avoid ground loop noise and oscillation only ground devices at this point that are not grounded elsewhere. 10. POWER CORD: Nominal 115 VAC verify that the curcuit is grounded before use. 11.SPEAKER OUTPUT: Consists of 12 AWG bindingpost/banana type connectors and 1/4" phone jacks. Connect as indicated above.
