THISAMPLIFIER IS NOT SUITABLE FOR OPERATION OUTSIDEOR IN HARSH ENVIRONMENTS.During the warrantyperiod, the manufacturer will, at its option, either repair ofreplace products which prove to be defective.For warranty service or repair, this product must beproperly packed and returned to a service facilitydesignated by the manufacturer.Buyer shall prepayshipping charges to the designated facility and themanufacturer shall pay shipping charges to return theproduct to buyer. However, Buyer shall pay all shippingcharges, duties and taxes for products returned to themanufacturer from another country.The manufacturer does not warrant that the operationof the product will be uninterrupted or error-free.TheBuyer must determine the suitability of the product for hisor her purposes.LIMITATION OF WARRANTYThe foregoing warranty shall not apply to defectsresulting from improper or inadequate maintenance byBuyer, Buyer-supplied interfacing, unauthorizedmodification or misuse, operation outside of theenvironment specifications for the product includinginadequate ventilation, or improper site preparation,installation, or maintenance.NO OTHER WARRANTY IS EXPRESSED OR IMPLIED.THE MANUFACTURER SPECIFICALLY DISCLAIMS THEIMPLIED WARRANTIES OF MERCHANTABILITY ANDFITNESS FOR A PARTICULAR PURPOSE.EXCLUSIVE REMEDIESTHE REMEDIES PROVIDED HEREIN ARE BUYERSSOLEANDEXCLUSIVEREMEDIES.THEMANUFACTURER SHALL NOT BE LIABLE FOR ANYDIRECT, INDIRECT, SPECIAL, INCIDENTAL, ORCONSEQUENTIAL DAMAGES, WHETHER BASED ONCONTRACT, TORT, OR ANY OTHER LEGAL THEORY.SAFETY SYMBOLSThe following symbols are used throughout this manualand in the product.Familiarize yourself with each of thesymbols and its meaning before servicing this amplifier.Instruction manual symbol.The product willbe marked with this symbol when it is necessaryfor the user to refer to the instruction manual inorder to protect the unit against damage.Indicates dangerous voltages are present. Beextremely careful.The CAUTION sign denotes a hazard. It callsattention to a procedure which, ifnot correctly performed or adheredto, could result in damage to ordestruction of the amplifier.Do not proceed beyond aCAUTION sign until the indicated conditions are fullyunderstood and met.The WARNING sign denotes ahazard.It calls attention to aprocedure which, if not correctlyperformed or adhered to couldresult in injury or loss of life.Do not proceed beyond aWARNING sign until the indicated conditions are fullyunderstood and met.GENERAL SAFETY CONSIDERATIONSTHIS UNIT DOES NOT HAVE A POWER SWITCH;HAZARDOUS VOLTAGES ARE PRESENT WITHIN THEUNIT WHENEVER IT IS PLUGGED IN. This still applieswhen the over-temperature thermostat opens, as it mayautomatically reset at any time.There are voltages and hot components at many pointsin the amplifier which can, if contacted, cause seriousinjury. Be extremely careful. Any adjustments or serviceprocedures that require operation of the amplifier out of itsenclosure should be performed only by trained servicepersonnel.5Powered SubwooferTLX PS101. TROUBLE SHOOTING BEFORE OPENINGCheck connections, control settings, driver and otherpossible external problems. If there is Output, determine ifall controls and Inputs function properly. Rotate Pots overfull range while applying lateral and vertical oscillatingforces to locate possible intermittent function. High LevelInputs should be tested individually both differentially(signal from - to + with normal output) and in commonmode (signal from low level ground to both + and -shorted together, giving virtually no output). While passinga signal, corner drop the enclosure a few inches to exposepossible intermittent problems. Check woofer for rubbingof voice coil or tears in cone or surround. Check cabinetfor loose extraneous articles which may have been pushedinto front port.2. REMOVING THE AMPLIFIER.There are voltages and hot components at many pointsin the amplifier which can, if contacted, cause personalinjury. Be extremely careful. Any adjustments or serviceprocedures that require operation of the amplifier out of itsenclosure should be performed only by trained servicepersonnel. Refer to PCB drawings for locations of hazardsand familiarize yourself with their locations before starting.3. TROUBLE SHOOTING AFTER REMOVALVerify AC plug is disconnected See WARNINGS insection 2.To prevent loose hardware from reducing safetyspacings, it is essential that all hardware be replaced in thesame manner as it was removed, with lock washers underall nuts, proper torque on screws and thread locking sealeron the transformer nuts.If line core, its strain relief, or the AC switch arereplaced, it is necessary to seal them completely to panelwith an approved conformal coating to prevent airwhistling through any openings from woofer pressure.To reduce the risk or electric shock and/orfire, replace items as marked on schematicwith the safety marking only with the exactreplacements listed in the safety componentlist, section 5.If exact replacements are not available,order them from the factory or an authorized servicecenter.A.)Check fuse F1. If blown visually check transformerfor discoloration, and large capacitors (C36, C37) forbulges or venting. Check for shorts in Q3-Q7 withan Ohmmeter, (see schematic).B.With ohmmeter, verify contacts of thermostat areclosed, voice coil of woofer is 3.3 ohms andwindings of transformer are continuous.C.Examine board and wiring for obvious damage,broken or poorly soldered connections, ordiscoloration.D.Repair or replace items identified above.Procedures for replacing power transistors andremoving PCB are as follows:Use low power, grounded temperature regulated ironwith small tip such as Weller PTA7 and ESD control.Use SN63/37 solder 0.032 diameter with no cleanflux core, Alpha Metals P2 or equal.I)Replacing power transistors: Clip all 3 leadsnear body of transistor. Remove screw anddiscard device (keep hardware and insulator).Holding each lead in turn with needle noseBEFORE THIS AMPLIFIER IS PLUGGED IN, make sure its rated voltage corresponds to the voltage of the AC powersource to be employed. Failure to use the correct voltage could cause damage to the amplifier when the AC power cable isplugged in. Do not exceed the rated voltage by more than 10%; operation below 90% will degrade performance or cause theunit to shut off.6Powered SubwooferTLX PS10pliers, gently heat and remove cut lead fromhole in edge or PCB.Clean insulator and seating area on back ofpanel. Coat both sides of insulator with silicon(white) thermal compound (unless siliconerubber pads are provided), position it centeredon back of device with holes aligned. Insertleads into PCB then place pair over hole inpanel; ensure hole in insulator is aligned. Insertscrew from far side, pass shoulder bushing overscrew and carefully seat shoulder in hole in tab,add flat washer, lock washer and nut (fingertight). Center insulator tighten screw first thensolder all three leads in respective slots with fullfillet, being careful not to bridge pads. Useohmmeter to verify there is no short from tab oftransistor to panel, or between pads.Never operate amplifier with load connectedwhen PC assembly is not attached to panel orwhen any of output transistors is not properlyscrewed to panel.After repair, inspect for possible safety hazards,including loose hardware, missing lock washers, correctfuse and lead dress of primary wires (these must be held inposition with cable ties so that they cannot touchsecondary components).With ohmmeter, check thatpanel is connected to signal ground.It is essential that the following safety insulation test beperformed prior to returning the Power Sub-Woofer to thecustomer, using one of the following methods.A) Insulation Resistance TestWith a 500VDC Insulation Tester, Checkinsulation from the outer metal contact of theRCA jack (chassis) to the line neutral of ACcord. Resistance should be 100M.B) Hi-Pot TestIf a UL approved Hi-Pot tester is available, testline & neutral of AC cord to outer shell of RCAjack (chassis) at 1100VAC for 2 seconds.Observe all of instrument manufacturersinstructions and safety warnings in performingthis test.Connect sub-woofer system to a music source. Play athigh level while checking for air leaks around panel edge,driver, panel jacks and controls, and voice coil problemssuch as rubbing or loose turns.With the crossoverfrequency set to 50Hz, very little of the voice contentshould be heard.4.
