professional power amplifiers. Passive cooling with large heatsinks is used for low mechanical noise. Our patented trans·nova circuit topology and MOSFET output stage ensures trouble free, long term operation and is backed by our five year warranty. This manual contains information on using the P1500 and P3000 amplifiers. It is organized into three main sections. "Installation" covers the location and connection of the amplifier in the system. Like many precision components careful attention to the initial setup can yield dividends in higher performance and trouble-free use. "Operation" covers the controls and features of the amplifiers and how to use them to get the best effect. The "Technical Reference" section contains field service information. In addition to the schematic and parts list there are block diagrams and an explanation of circuit operation useful for technicians. We strongly urge reading over the Installation and Operation portions of this manual before putting the amplifier into service. The circuitry used in the P1500 and P3000 is the latest refinement of our trans·nova (TRANSconductance NOdal Voltage Amplifier, US Patent 4,467,288) circuit. It has been proven to offer sound quality to satisfy the most analytic audiophile or the most demanding professional. The natural sound and realistic reproduction have made trans·nova amplifiers preferred in many critical installations. Since our pioneering use of MOSFETs in the DH200 amplifier, they have proven extremely fault tolerant even in abusive situations. This sturdiness enables the amplifier to drive reactive speaker loads without the performance and sound penalties imposed by elaborate protection schemes. Specialized circuits prevent damage to the amplifiers and speakers without affecting the audio signal. A soft start circuit prevents sending potentially destructive turn-on and turn-off transients to the speakers. A thermal sensing network monitors the heatsink temperature and shuts down the amplifier to protect from excessive operating heat. The need for internal fuses has been eliminated; a sensing circuit monitors the output and shuts down operation when it detects a short in the output load. Each channel of these amplifiers is built as a self-contained module which only requires mounting the heatsink and connection to the chassis-mounted transformer and binding posts to be fully functional. The circuit board contains all the operational components. This modular arrangement simplifies construction and improves service accessibility. The circuit board assembly makes extensive use of surface mount components in the low power portion of the audio circuitry. Automated equipment is used to place and solder the components which yields greater uniformity and reliability. The front panel has controls for input level adjustment and the power switch. In addition, LED indicators give a visual representation of the operating status of each channel. The THERMAL and SHORT indicators light to show when these protection circuits have been activated. The CLIP indicator helps prevent damaging the speakers by showing when the amplifier is overdriven. The SIGNAL indicator lights to show the presence of an audio signal. ­1­ ­6 ­3 ­3 ­6 P3000 ­15 0dB ­15 0dB trans nova channel 2 channel 1 Front Panel View ­ 3 sh o th rt er m cl al ip pi ng sig na l ­1 sig na l cl ip p in g th er m a sh l or t ­10 ­1 ­10 PUSH ­2­ ­+ XLR Connections CAUTION RISK OF ELECTRIC SHOCK DO NOT OPEN ® Mono Output: · Use CH 1 Input ONLY · Set CH 2 Gain to Max · Set Output Level with CH 1 Gain Control 1 Phone Connections 2 + !

The amplifiers can also produce considerable heat in normal operation so the primary consideration when determining a location for the amplifiers is to allow for adequate ventilation. The large heatsinks provide unrestricted airflow, but care must be taken to keep the slots in the bottom panel and top cover clear. If the amplifier is mounted in an equipment rack, make sure adjacent equipment does not impede cool air flow. ! Rack systems should have two fans 4" to 5" in from the front of the amplifier blowing upward. Inadequate ventilation can shorten component life, especially when other equipment raises the ambient air temperature, so circulating fans should be considered in tight quarters. 4" to 5" (from fan center) (Bottom View) Fan center approximately in line with edge of unit and starting of heat sink fins · Fans placed 4" to 5" from front of unit · Fans placed under the unit pointing upwards · Recommended P1500 fan is 32 CFM x 2 · Recommended P3000 fan is 100 CFM x 2 AC LINE The P1500U and P3000U operate from a 120 volt, 60Hz AC power line. The P1500CE and P3000CE operate from a 230 volt, 50-60Hz AC power line. Connection is made by a 16 gauge, IEC Type 320, grounded line cord. For safety considerations only a properly grounded (earthed) receptacle should be used. If a grounded circuit is not available do not break off the ground pin; use the proper adapter plug for a two wire receptacle. Mounted on the rear panel is the line fuse which interrupts the power to the amplifier. If this fuse blows replace it only with the same type and rating fuse. The correct replacement fuse value is printed on the rear panel of the amplifier. If the new fuse blows, this is an indication of a fault with the amplifier. Servicing should be performed only by a qualified technician. ­3­ INPUT The input jacks located on the back of the amplifier are dual function connectors which accept 1/4" Phone (Tip Ring Sleeve) or XLR plugs. The 1/4" Phone jack is connected according to conventional usage. The XLR jack is connected according to the IEC and AES standard. XLR Balanced Input Check output of source unit for proper signal polarity 1/4" TRS Balanced Input Check output of source unit for proper signal polarity INPUT Pin 1 = GND Pin 2 = (+) Pin 3 = (­) 1 2 GND ­ + FROM SOURCE Tip = (+) Ring = (­) Sleeve = GND INPUT FROM SOURCE 3 + ­ SHIELD Many popular mixers use unbalanced outputs and can be used with the Hafler amplifier. To minimize residual ground noise, we recommend using twisted pair cable or short cable lengths in this type of configuration.

Ground switch in Chassis position, Mono switch in 2-Channel position. P1500 differences shown on parts list. Removable Center Spread Removable Center Spread OUTPUT CONNECTIONS The speaker output connectors are dual binding posts. These binding posts will directly accept 12 AWG wire or banana plugs and are spaced on 3/4" centers to accept dual banana plugs. MONOPHONIC USE For systems with high power requirements, the amplifiers can be configured for single channel bridged mono operation. To bridge the amplifier, set the rear panel Mono/2 Channel switch to the Mono position. The Channel 1 input and level control is used and the Channel 2 level control must be set to its maximum gain position. The speaker is connected to the RED output binding posts. ! ! When the amplifier is bridged the output is floating. Any speaker which requires a common ground from the amplifier output cannot be used in this application. Since a bridged amplifier shares the load between the two channels, each channel will effectively drive half of the load. Therefore, for bridged mono operation we recommend using an eight ohm load as the minimum impedance. OPERATION POWER SWITCH The POWER switch is located on the front panel of the amplifier. An internal lamp indicates when it is turned on. ! Standard practice is to turn the amplifier on last and off first when switching components to prevent sending damaging transients to the speakers. It is possible to leave the power switch in the on position and switch the amplifier remotely through a power distribution block or preamp switched outlet. When doing so make sure the switch is rated for the current required by the amplifier. LEVEL CONTROLS The input sensitivity for each channel can be adjusted individually using the level controls on the front panel. The gain control on an amplifier is usually fully advanced to its maximum (rated) sensitivity. In public systems where it is necessary to match levels, the knobs can be removed and the controls adjusted with your fingers or a flathead screwdriver. Cover the holes with the enclosed plugs to restrict access. MONO SWITCH Conventional two-channel stereo operation is obtained with the MONO/2 CH switch in the 2-Channel position. For high powered single channel use, switch to MONO and use the Channel 1 input and connect the speaker to the RED binding posts. ! For thermal considerations we do not recommend using less than an eight ohm load on the amplifier when running it in mono. When the switch is set in the mono position, the Channel 1 (+) and (­) inputs are connected to the Channel 2 in reversed polarity, which inverts the Channel 2 output. The gain is controlled by the Channel 1 level adjustment; set Channel 2 to maximum. ­7­ SHORT CIRCUIT PROTECTION Due to the self-protecting properties of the output power MOSFETs, there is no need for sonically degrading voltage and current limiting circuits. To protect the amplifier from problems which may occur in the speaker line there is an overload detection circuit. In the event of a short in the speaker load or cables, the speaker detection circuit will shut down that channel and light the front panel SHORT indicator. If this happens, correct the fault and turn the amplifier off, then back on to reset. ! LED INDICATORS Amplifier operation is monitored internally and each channel has four status LEDs. These indicators can be used for system troubleshooting in case of aberrant behavior. Signal Clipping Thermal Short Monitors the amplifier output and lights when a signal is present. The SIGNAL indicator is calibrated to activate at an equivalent input voltage of 30mV. Monitors the DRIVE SIGNAL and lights when the drive signal voltage exceeds the maximum for linear operation of the output MOSFETs. Indicates when the thermal protection has shut down the amplifier. This occurs when the heatsink temperature exceeds 90° C. Indicates when the output overload monitor detects a potentially damaging short and shuts down amplifier operation. After clearing the fault, restore normal function by turning the amplifier off, then on again. WARM UP In order to achieve the best sonic performance from the amplifier, we recommend letting it warm up for 1 hour before beginning any critical listening. The amplifier may not deliver its full potential sound quality before this time has passed. CLEANING AND MAINTENANCE There is no requirement for regular maintenance on the electronic components of the amplifier. If the case becomes soiled it can be cleaned using a soft cloth and a mild detergent, such as spray window or glass cleaner. If the amplifier is located in a particularly dusty environment cleaning the inside with compressed air or vacuuming every 18 to 24 months is sufficient. ­8­ PC BOARD LAYOUT C1221 Z3 Z Z2 C121 P4 P2 R165 P1 P3 X4 X3 ROCKFORD CORP PC-0812-H M.ALBERS C33 R32 SW2 J8 R134 R131 Q9 Q10 R132 R40 Q12 R133 Q11 R138 R130 Q5 R35 C36 J2 Q4 Q116 R34 C124 TS1 J3 Q115 R127 R41 CR12 R141 C116 C115 J4 R140 R136 R21 C126 R164 CR15 R17 R20 R19 C123 C1 R64 R1 C35 C125 R159 CH 1 J1 C114 R31 CR11 R18 C120 C119 R24 C112 R139 C8 R129 C113 Q105 R128 Q6 Q7 Q104 R124 Q103 R33 R14 R39 R7 J7 R9 C19 R6 C22 R10 R16 R48 CR14 JW4 JW5 JW6 Q8 U2 R11 CR4 R53 R49 R58 J5 C21 R61 R8 R123 CR6 CR5 CR13 U4 C29 R12 Q3 CR7 CR8 C31 Q1 R5 R13 R60 C28 CR3 R51 R54 C20 R43 C15 R46 R47 C26 R44 R45 R42 R63 C16 R28 R27 CR9 R15 C23 C17 R38 SW1 R62 R59 C18 Q2 R29 U1 J6 R50 U5 R56 R30 R4 R26 R57 R25 C25 C13 C4 C5 C3 R135 R52 CR2 D1 D2 CT2 AC3 X5 AC4 C24 JW7 AC1 CT1 AC2 C6 C7 R37 C30 CR1 R55 R22 R23 P5P6 X2 X1 JW3 JW2 JW1 ARTWORK COMPONENT SIDE revised 12/12/96 R36 R2 R3 C14 F3 C9 CR10 F2 C10 C2 ­9­ PARTS LIST P3000U 120VAC, 60Hz DESIGNATOR VALUE ALL RESISTORS IN OHMS, 1/4W R1 R2 R3 R4 R5 R6 R7 R8 R9 R10 R11 R12 R13 R14 R15 R16 R17 R18 R19 R20 R21 R22 R23 R24 R25 R26 R27 R28 R29 R30 R31 R32 R33 R34 R35 R36 R37 R38 R39 R40 R41 R42 R43 R44 R45 R46 R47 R48 R49 R50 R51 R52 56.2k 1k 47k 47k 4.7k 1.07k 909 200, Trim Pot 1k 28k 10M 28k 470k 16 3.3M 4.7k 10k 100k 604k 45.3k 2.2M 100k 100k 10k Pot 820 2.2M 316 316 3.92k 3.92k 100 100 16 470 220 1k 1k 3.3M 1k 3k 6.8k 10k 15k 10k 15k 47k 47k 15k 10k 4.7k 4.7k 15k PART # RMP/4-5622 RM/4-102C RM/4-473C RM/4-473C RM/4-472C RM/4-1071C RM/4-9090C RVH-201 RM/4-102C RMP/4-2802 RMP/4-106C RM/4-2802C RM/4-474C RM/4-160C RM/4-335C RM/4-472C RM/4-103C RM/4-104C RM/4-6043C RM/4-4532C RM/4-225C RM/4-104C RM/4-104C RV-0818 RM/4-821C RM/4-225C RM/4-3160C RM/4-3160C RM/4-3921C RM/4-3921C RM/4-101C RM/4-101C RM/4-160C RM/4-471C RM/4-221C RM/4-102C RM/4-102C RM/4-335C RM/4-102C RM/4-302C RM/4-682C RM/4-103C RM/4-153C RM/4-103C RM/4-153C RM/4-473C RM/4-473C RM/4-153C RM/4-103C RM/4-472C RM/4-472C RM/4-153C DESIGNATOR VALUE R53 R54 R55 R56 R57 R58 R59 R61 R62 R63 R64 R123 R124 R127 R128 R129 R130 R131 R132 R133 R134 R135 R136 R138 R139 R140 R141 R159 R164 TS1 SW1 C1 C2 C3 C4 C5 C6 C7 C8 C9 C13 C14 C15 C16 C17 C18 C19 C20 2.2M 10k 100k 15k 10k 100k 10k 100k 2.2M 28k 100k 2k 820 1k 100 100 1k 3k 3k 3k 100 1k 200, Trim Pot 100 470 1k 470 470 220 Thermistor DPDT Switch 680pF, 100V 0.22µF, 50V 6800µF, 80V 0.22µF, 250V 6800µF, 80V 270pF, 50V 270pF, 50V 4.7pF, 100V 0.1µF, 50V 470µF, 50V 470µF, 50V 0.1µF, 50V 0.1µF, 50V 0.1µF, 50V 0.1µF, 50V 0.1µF, 50V 0.1µF, 50V PART # RM/4-225C RM/4-103C RM/4-104C RM/4-153C RM/4-103C RM/4-104C RM/4-103C RM/4-104C RM/4-225C RM/4-2802C RM/4-104C RM/4-202C RM/4-821C RM/4-102C RM/4-101C RM/4-101C RM/4-102C RM/4-302C RM/4-302C RM/4-302C RM/4-101C RM/4-102C RVH-201 RM/4-101C RM/4-471C RM/4-102C RM/4-471C RM/4-471C RM/4-221C SS-1519-A SW-0280 CDS-681DBAA CYV-224 CERS-688D CY-224AC CERS-688D CDS-271CAAA CDS-271CAAA CDS-047DBAA CDS-104CCDB CER-477C-024 CER-477C-024 CDS-104CCDB CDS-104CCDB CDS-104CCDB CDS-104CCDB CDS-104CCDB CDS-104CCDB ­ 10 ­ DESIGNATOR C21 C22 C23 C24 C25 C26 C28 C29 C30 C31 C33 C35 C36 C112 C113 C114 C115 C116 C119 C120 Q1 Q2 Q3 Q4 Q5 Q6 Q7 Q8 Q9 Q10 Q11 Q12 Q103 Q104 Q105 Q115 Q116 CR1 CR2 CR3 CR4 CR5 CR6 CR7 CR8 CR9 CR10 CR11 CR12 CR13 VALUE 10µF, 16V 10µF, 16V 0.47µF, 50V 0.47µF, 50V 0.1µF, 50V 1µF, 50V 47µF, 16V 10µF, 50V 0.1µF, 50V 0.1µF, 50V 0.1µF, 50V 47pF, 200V 22pF, 200V 100µF, 25V 100µF, 25V 100pF, 50V 100pF, 50V 0.047µF, 50V 0.1µF, 100V 0.1µF, 100V MMBT3904LT1 LM-317 LM-337 2SK1058 2SJ162 MMBT5088L MMBT5088L MMBT3904LT1 MPS-A56 MPS-A56 MPS-A06 MPS-A06 MMBTA06L MMBT3906LT1 MMBT3906LT1 2SK1058 2SJ162 Red LED Red LED Red LED Green LED MMBD914L Diode MMBD914L Diode MMBD914L Diode MMBD914L Diode Bridge Rectifier 15A Bridge Rectifier 1.5A BAV99L Dual Diode BAV99L Dual Diode MMBD914L Diode PART # CER-106SM CER-106SM CYV-474 CYV-474 CDS-104CCDB CER-105C-024 CER-476-024 CER-106C-024 CDS-104CCDB CDS-104CABB CDS-104CCDB CM-470-024 CM-200-024 CER-107A-024 CER-107A-024 CDS-101CAAA CDS-101CAAA CYV-473 CY-104 CY-104 SS-0792 SS-239 SS-240 SSH-741T SSH-740T SS-0114 SS-0114 SSS-0792 SS-101A SS-101A SS-102A SS-102A SS-102SM SS-0791 SS-0791 SSH-741T SSH-740T SS-741 SS-741 SS-741 SS-740 SS-803SM SS-803SM SS-803SM SS-803SM SS-0801 SS-0800 SS-260SM SS-260SM SS-803SM DESIGNATOR VALUE CR14 BAV99L Dual Diode CR15 BAV99L Dual Diode U1 U2 U4 U5 TL072CD Dual Opamp TL072CD Dual Opamp LM339 Comparator LM339 Comparator Power Switch IEC Connector IEC Line Cord Dual Binding Post P3000 Transformer Fuse, 1A Fast Fuse, 1A Fast Fuse, 5A Slo Blo PART # SS-260SM SS-260SM SS-143SM SS-143SM SS-730SM SS-730SM SWH-1009 CC-0852 FAH-146 CC-0867 TT-1531 FS-1592 PS-1592 FS-005SB ! ! !
