SAFETY

12、 SYMBOLS The following symbols are used throughout this manual and in the product.Familiarize yourself with each of the symbols and its meaning before servicing this amplifier. Instruction manual symbol.The product will be marked with this symbol when it is necessary for the user to refer to the ins

13、truction manual in order to protect the unit against damage. Indicates dangerous voltages are present. Be extremely careful. The CAUTION sign denotes a hazard. It calls attention to a procedure which, if not correctly performed or adhered to, could result in damage to or destruction of the amplifier

14、.Do not proceed beyond a CAUTION sign until the indicated conditions are fully understood and met. The WARNING sign denotes a hazard.It calls attention to a procedure which, if not correctly performed or adhered to could result in injury or loss of life.Do not proceed beyond a WARNING sign until the

15、 indicated conditions are fully understood and met. GENERAL SAFETY CONSIDERATIONS THIS UNIT DOES NOT HAVE A POWER SWITCH; HAZARDOUS VOLTAGES ARE PRESENT WITHIN THE UNIT WHENEVER IT IS PLUGGED IN. This still applies when the over-temperature thermostat opens, as it may automatically reset at any time

16、. There are voltages and hot components at many points in the amplifier which can, if contacted, cause serious injury. Be extremely careful. Any adjustments or service procedures that require operation of the amplifier out of its enclosure should be performed only by trained service personnel. Radio

17、Fans.CN 收音机爱 好者资料库 5 Powered SubwooferTLX PS10 1. TROUBLE SHOOTING BEFORE OPENING Check connections, control settings, driver and other possible external problems. If there is Output, determine if all controls and Inputs function properly. Rotate Pots over full range while applying lateral and verti

18、cal oscillating forces to locate possible intermittent function. High Level Inputs should be tested individually both differentially (signal from - to + with normal output) and in common mode (signal from low level ground to both + and - shorted together, giving virtually no output). While passing a

19、 signal, corner drop the enclosure a few inches to expose possible intermittent problems. Check woofer for rubbing of voice coil or tears in cone or surround. Check cabinet for loose extraneous articles which may have been pushed into front port. 2. REMOVING THE AMPLIFIER. There are voltages and hot

20、 components at many points in the amplifier which can, if contacted, cause personal injury. Be extremely careful. Any adjustments or service procedures that require operation of the amplifier out of its enclosure should be performed only by trained service personnel. Refer to PCB drawings for locati

21、ons of hazards and familiarize yourself with their locations before starting. 3. TROUBLE SHOOTING AFTER REMOVAL Verify AC plug is disconnected See WARNINGS in section 2. To prevent loose hardware from reducing safety spacings, it is essential that all hardware be replaced in the same manner as it wa

22、s removed, with lock washers under all nuts, proper torque on screws and thread locking sealer on the transformer nuts. If line core, its strain relief, or the AC switch are replaced, it is necessary to seal them completely to panel with an approved conformal coating to prevent air whistling through

23、 any openings from woofer pressure. To reduce the risk or electric shock and/or fire, replace items as marked on schematic with the safety marking only with the exact replacements listed in the safety component list, section 5.If exact replacements are not available, order them from the factory or a

24、n authorized service center. A.)Check fuse F1. If blown visually check transformer for discoloration, and large capacitors (C36, C37) for bulges or venting. Check for shorts in Q3-Q7 with an Ohmmeter, (see schematic). B.With ohmmeter, verify contacts of thermostat are closed, voice coil of woofer is

25、 3.3 ohms and windings of transformer are continuous. C.Examine board and wiring for obvious damage, broken or poorly soldered connections, or discoloration. D.Repair or replace items identified above. Procedures for replacing power transistors and removing PCB are as follows: Use low power, grounde

26、d temperature regulated iron with small tip such as Weller PTA7 and ESD control. Use SN63/37 solder 0.032 diameter with no clean flux core, Alpha Metals P2 or equal. I)Replacing power transistors: Clip all 3 leads near body of transistor. Remove screw and discard device (keep hardware and insulator)

27、. Holding each lead in turn with needle nose BEFORE THIS AMPLIFIER IS PLUGGED IN, make sure its rated voltage corresponds to the voltage of the AC power source to be employed. Failure to use the correct voltage could cause damage to the amplifier when the AC power cable is plugged in. Do not exceed

28、the rated voltage by more than 10%; operation below 90% will degrade performance or cause the unit to shut off. 6 Powered SubwooferTLX PS10 pliers, gently heat and remove cut lead from hole in edge or PCB. Clean insulator and seating area on back of panel. Coat both sides of insulator with silicon (

29、white) thermal compound (unless silicone rubber pads are provided), position it centered on back of device with holes aligned. Insert leads into PCB then place pair over hole in panel; ensure hole in insulator is aligned. Insert screw from far side, pass shoulder bushing over screw and carefully sea

30、t shoulder in hole in tab, add flat washer, lock washer and nut (finger tight). Center insulator tighten screw first then solder all three leads in respective slots with full fillet, being careful not to bridge pads. Use ohmmeter to verify there is no short from tab of transistor to panel, or betwee

31、n pads. Never operate amplifier with load connected when PC assembly is not attached to panel or when any of output transistors is not properly screwed to panel. After repair, inspect for possible safety hazards, including loose hardware, missing lock washers, correct fuse and lead dress of primary

32、wires (these must be held in position with cable ties so that they cannot touch secondary components).With ohmmeter, check that panel is connected to signal ground. It is essential that the following safety insulation test be performed prior to returning the Power Sub-Woofer to the customer, using o

33、ne of the following methods. A) Insulation Resistance Test With a 500VDC Insulation Tester, Check insulation from the outer metal contact of the RCA jack (chassis) to the line neutral of AC cord. Resistance should be 100M. B) Hi-Pot Test If a UL approved Hi-Pot tester is available, test line & neutr

34、al of AC cord to outer shell of RCA jack (chassis) at 1100VAC for 2 seconds. Observe all of instrument manufacturers instructions and safety warnings in performing this test. Connect sub-woofer system to a music source. Play at high level while checking for air leaks around panel edge, driver, panel

35、 jacks and controls, and voice coil problems such as rubbing or loose turns.With the crossover frequency set to 50Hz, very little of the voice content should be heard. 4.
