MODEL 9505CE T8A 250V 230 V~ 50/60Hz 662W Rear Panel View INSTALLATION LOCATION The 9505 power transformer can generate a substantial magnetic field, so caution should be exercised in the placement of low level components such as a tape deck, mixer or mic preamp to avoid inducing noise in the low level circuitry. 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. Los sistemas empotrados en gabinetes (rack), deben tener dos (2) ventiladores soplando hacia arriba, ubicados de 10 a 12.5 ctms. detrás del frente del amplificador. Les chaines stéreo Rack devraient avoir deux ventillateurs placés à 4 ou 5 centimètres, en face de l'amplificateur. Rack Systeme sollten zwei eingebaute Ventilatoren haben, die Luft von oben auf den Verstärker leiten. Die Ventilatoren sollten ca. 10-20cm hinter der Front des Verstärkers angebracht werden. Per i sistemi ad armadio sono necessari due ventilatori direzionati in su collocati dai 10 ai 13 centimetri davanti all'amplificatore. 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 heatsink fins · Fans placed 4" to 5" from front of unit · Fans placed under the unit pointing upwards · Recommended 9505 fan is 50cfm x 2 AC LINE The 9505 amplifier operates from a 120 volt, 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 UNBALANCED INPUT The unbalanced inputs use conventional RCA phone jacks. Set the BALANCED/UNBALANCED switch to the UNBALANCED position to use these jacks. BALANCED 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 Balanced inputs. To minimize residual ground noise, we recommend using twisted pair cable or short cable lengths in this type of configuration. XLR Unbalanced Input Connect (­) and GND (shield) terminals at both ends of cable to prevent unstable amplifier operation 1/4" TRS Unbalanced Input INPUT INPUT Pin 1 = GND Pin 2 = (+) Pin 3 = GND SHIELD FROM SOURCE Tip = (+) Sleeve = GND + + FROM SOURCE 1 2 3 SHIELD 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 Ch switch to the Bridged Mono position. Only the Channel 1 input and level control is used. The speaker is connected to the RED output binding posts. ­4­ ! ! ! ! ! ! ! ! ! ! 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. Cuando el amplificador esté en modo puente (bridge), la salida del mismo es flotante (sin neutro). Cualquier parlante que necesite una tierra común de la salida del amplificador, no puede ser usado cuando el modo puente esté activado. Lorsque l'amplificateur est relié, la puissance de rendement est émise. Tout haut-parleur nécessitant l'utilisation d'une même fiche que celle de l'amplificateur, ne peut pas être utilisé dans cette application. Wenn der Verstärker gebrückt wird, ist der Ausgang schwimmend geerdet. Alle Lautsprecher, die allgemeine Masse vom Verstärker nutzen, können in dieser Konfiguration nicht eingesetzt werden. Nel caso di un'amplificatore ostruito, l'uscita é fluttuante non utilizzare in questa applicazione un altoparlante che richiede la messa a terra in comune con l'uscita dell'amplificatore. 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. Ya que un amplificador en puente comparte la carga entre los dos canales, cada canal manejará efectivamente la mitad de la carga. Por lo que, para la operación en modo puente (mono) recomendamos el uso de una carga de ocho ohmios como la mínima impedancia. Étant donné que l'amplificateur, une fois connecté, distribue la même charge entre les deux canaux, chaque canal conduira, de façon efficace, la moitié de la charge. C'est pourquoi, pour les opérations conduites en "mono", nous recommandons l'utilisation d'une charge de huit ohm comme impédance minimale. Wird der Verstärker gebrückt, "sieht" dieser nur die halbe angelegte Last. Aus diesem Grund geben wir für die gebrückte mono Operation eine minimale Last von 8 Ohm vor. Visto che un'amplificatore ostruito divide il carico tra i due canali, ogni singolo canale in effetti conduce meta del carico. Quindi, per il funzionamento monofonico ostruito dell'amplificatore si raccomanda l'utilizzo di un carico di 8 ohm impedenza minima. 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. Es costumbre encender el amplificador de último y apagarlo de primero cuando se estan encendiendo/ apagando otros equipos, para así evitar el envío de transientes dañinas a los parlantes. Il est de pratique courante de commencer par tourner l'amplificateur sur "off" et de terminer par "on," lorsqu'il s'agit de prévenir l'envoie de passages nuisible aux haut-parleurs. Der Verstärker sollte als letztes Gerät eingeschaltet und als erstes Gerät wieder ausgeschaltet werden, um eine Beschädigung der Lautsprecher durch spannungsspitzen zu vermeiden. L'uso comune consiglia l'accensione dell'amplificatore per ultimo e lo spegnimento per primo quando si accendono i vari componenti, per evitare l'invio di transitori danneggianti agli altoparlanti. 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. ­5­ INPUT CONFIGURATION SWITCH Mono / 2 Ch Theamplifieroperatesintwo-channelmodewhentherearpanelMono/2Ch switchisinthe2Chposition.Tousetheamplifier insinglechannel,bridgedmonoapplications,thefrontpanelswitchmustbeintheMonoposition.WheninMono,theChannel 1 (+) and (­) inputs are connected to Channel 2 in reversed polarity, which inverts the Channel 2 output.

GROUND SWITCH Ground loops are characterized by a hum or buzz in the system and are caused by a voltage potential difference between two points in a ground circuit. Ground loops are aggravated when multiple paths exist for a given circuit. Mounting components in a rack with metal rails may introduce ground loops between associated equipment, because the rails can establish an additional ground path. The CHASSIS/FLOAT switch allows you to select the amplifier grounding scheme for best system compatibility. With the switch in the CHASSIS position all signal grounds are referred to the chassis and power line ground. In the FLOAT position the signal ground is decoupled from the chassis. The position of the switch is determined by the overall noise in the system; choose the position which gives the lowest hum. LOAD FAULT PROTECTION Because of the self-protecting properties and fault tolerance of the lateral MOSFETs used in the 9505, elaborate voltage and current limiting protection schemes are not necessary. To prevent damage to the amplifier from a fault in the loudspeaker load, the power supply B+ and B­ rails are fused. Check these fuses if the sound is garbled or there is no output. The fuses should not blow under normal use and a blown fuse is usually an indication of a fault. The fault could be a bad connection, a problem with the speaker or a short in the speaker line. Disconnect power to the amplifier before removing the cover. 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 will 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. ­6­ PC BOARD LAYOUT ­7­ SCHEMATIC DIAGRAM NOTES: Unless specified otherwise 1.

HIGH VOLTAGE POWER SUPPLY LOW VOLTAGE POWER SUPPLY SOFT TURN ON/OFF SYSTEM ­ 12 ­ TECHNICAL REFERENCE THEORY AND OPERATION OF trans·nova The (TRANSconductance NOdal Voltage Amplifier) principle is based on our 1984 U.S. Patent 4,467,288. This patent describes the advantages of audio power amplifiers in which a MOSFET output stage is connected in a grounded source configuration. In this connection the output stage has its full voltage gain of typically 20dB (ten times), instead of the usual 1dB loss of voltage follower designs. It is an inevitable result of electrical physics that this output with gain inherently increases the power gain (for the same bandwidth) of the output stage by typically ten times over the conventional follower connection, using exactly the same MOSFET devices. The output stage is thus now ten times less wasteful of its incoming drive power. The driver stage can now be of a low voltage (±24 volts) nature and be designed along the same principles always used in high quality preamplifiers: Class A operation, high linearity, and wide bandwidth. A topology utilizing an output stage with gain yields a much simpler, shorter total signal path than that of the usual high voltage driver designs. The number of serial stages is reduced from five or more, to only three. But all of the above does not make an amplifier trans·nova. The output stage is further refined into a trans-impedance stage (current-to-voltage converter), to achieve extremely short loop (fast) negative feedback. The output stage is driven cooperatively by a transconductance stage (voltage-to-current converter). The 9505 is the most sophisticated amplifier we have yet developed utilizing the basic trans·nova principle. And, although the measured specifications are very good, the numbers do not describe the realistic sound of the amplifiers. CIRCUIT IMPLEMENTATION Earlier models of amplifiers we have offered using the trans·nova topology have earned the reputation for clean, natural sounding reproduction. A conservative, purist design approach was used to avoid compromising the desirable characteristics of the trans·nova circuits. Circuit innovation was not prevented by this conservatism; as is evident in the discoveries which resulted in development of the DIAMOND circuitry to be discussed shortly, and the novel balanced input system. Many "balanced" amplifiers are merely conventional unbalanced designs with a Balanced-to-Unbalanced converter (usually IC op-amp based) preceding the power amplifier. The 9505, however, is a true differential input power amplifier. Each (+) and (­) input port has been buffered to allow direct signal access to the differential amplifier, without conversion to unbalanced form. Deactivating the Balanced Mode is accomplished via a rear panel switch that grounds the (­) inputs, effectively converting the amplifier to unbalanced operation. The input stage is a JFET differential amplifier. This circuit configuration results in excellent front end headroom and extremely low intermodulation effects. The ultra low noise characteristic of the JFETs virtually eliminates noise "mixing" (intermodulation) with the music signal, reducing discordant product frequencies known as "noise grain" or "noise fuzz." A servo integrator has been employed to establish minimal DC offset. This circuit monitors the DC offset at the output of the amplifier, and injects an equal but opposite DC voltage into the (+) port of the differential input, thereby cancelling the offset. This method eliminates the need for a sonically degrading electrolytic capacitor in the audio path, and provides superior subsonic frequency response. ­ 13 ­ The final output stage utilizes lateral MOSFETs; four pairs are used for each channel in the 9505. These devices, unlike conventional bipolar transistors do not exhibit "thermal runaway." Thermal runaway is a phenomenon whereby a transistor heats up as it draws more current, which causes it to get hotter, and conduct more current, and so on until the device self destructs. Since the MOSFETs are inherently self protecting, no sonically degrading, complex circuitry is required to monitor and protect the devices. The lateral MOSFETs also have a linear input to output transfer function. Their connection in circuits and their operating characteristics are very similar to vacuum tubes, which is perhaps responsible for their widely recognized sonic trait of being "musical" and non-fatiguing. Operation of the transconductance stage is a major factor in the reproduction quality of the amplifier. The number of MOSFETs used at the output stage of the 9505 imposes sufficient capacitive load on the transconductance stage that if a conventional Class A stage were used (having intrinsically a 2:1 limit on peak-to-quiescent current) it would begin to show "stress" at the higher audio frequencies. The newly perfected DIAMOND (Dynamically Invariant AMplification Optimized Nodal Drive [patent pending]) driver stage satisfies the current headroom requirement by smoothly and continuously varying the current transfer ratios of the two transconductance paths, under the control of the signal current itself. This implementation allows the current transfer ratio of one path to be smoothly and continuously reduced to zero while the other is smoothly and continuously increased by a factor of two. What is remarkably new here is that when this normally-limiting 2:1 value is reached there is now about 14dB of additional, perfectly linear current headroom left to drive the MOSFETs! The result is a dramatic decrease in high-frequency distortion combined with higher ultrasonic stability ­ the "Holy Grail" of amplifier design. The power supply utilizes a UI style transformer with a separate primary for each channel. The transformer has a separate secondary for each channel high voltage power supply, each feeding a conventional split full wave bridge rectifier. High voltage power supply capacitance is 20,000µF per rail for each channel of the 9505. The third transformer secondary feeds a regulated supply for the input stage and driver circuitry. Low voltage power supply capacitance is 1,000µF per rail, with additional decoupling for each channel. WARNING: Only a competent technician should attempt the following procedure. PRECAUCION: Sólo un técnico competente debe intentar efetuar el siguiente procedimiento. MISE EN GARDE: Seul un technicien compétent devrait procéder à l'opération suivante. WARNUNG: Nur ein speziell geschulter Techniker sollte die nachfolgende Prozedur durchführen. AVVISO: La seguente procedura va eseguita soltanta da un tecnico di competenza. CALIBRATION Common Mode Rejection: The input common mode null is adjusted by the trim pot R1 (R101 for the left channel). The CMRR should be greater than 75dB below rated output. If the CMRR requires adjustment, feed the amplifier input with a common mode signal and adjust R1. Disconnect the power to the amplifier before removing the cover. Use a sinewave generator set to 1 volt output at 1kHz. Connect the generator signal output to the tip and ring of a 1/4" plug and ground to the sleeve. Plug this into the amplifier input. Connect an AC voltmeter to the amplifier output binding posts. Adjust R1 to give the lowest voltage output from the amplifier. For a temporary adjustment when a signal generator and voltmeter are not available, use an FM tuner and tune it to an unused station as your signal source, and connect the output to the amplifier as described above. Connect the amplifier output to a small full range speaker and adjust R1 for the lowest output from the speaker. Bias: The bias control establishes the quiescent Class AB output current of the amplifier. The bias should not need readjustment from the factory setting; however, if the amplifier is repaired and output devices have been changed, or if the two channels of the amplifier do not run at the same temperature, calibrating the bias is necessary. Disconnect the power to the amplifier before removing the cover. To adjust the bias, disconnect the input and speakers and remove the B+ fuse for that channel. Connect an amp meter across the now vacant fuse clips and adjust R45 (R145 for the left channel) to get a current reading of 400mA for the 9505. ­ 14 ­ SE R V I C E P O L I C Y AND LI M I T E D WA R R A N T Y Rockford Corporation (Hafler Division) offers a limited warranty on Hafler products on the following terms: · Length of Warranty 5 years on P1000, P1500, P3000, P4000 7 years on 9505 and P7000 90 days on all B-Stock (receipts are required) · What is Covered This warranty applies only to products sold to the original owner (non-transferable).
