2、unted 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

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 convention

7、al usage. The XLR jack is connected according to the IEC and AES standard. 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 syste

8、ms 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 bindi

9、ng 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 est en modo puente (bridge), la salida del mismo es flotante (sin neutro). Cualquier parlante que nece

Nel caso di unamplificatore ostruito, luscita fluttuante non utilizzare in questa applicazione un altopar

12、lante che richiede la messa a terra in comune con luscita dellamplificatore. 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.

13、Ya que un amplificador en puente comparte la carga entre los dos canales, cada canal manejar efectivamente la mitad de la carga. Por lo que, para la operacin en modo puente (mono) recomendamos el uso de una carga de ocho ohmios como la mnima impedancia. tant donn que lamplificateur, une fois connect

14、, distribue la mme charge entre les deux canaux, chaque canal conduira, de faon efficace, la moiti de la charge. Cest pourquoi, pour les oprations conduites en “mono”, nous recommandons lutilisation dune charge de huit ohm comme impdance minimale. Wird der Verstrker gebrckt, “sieht” dieser nur die h

15、albe angelegte Last. Aus diesem Grund geben wir fr die gebrckte mono Operation eine minimale Last von 8 Ohm vor. Visto che unamplificatore ostruito divide il carico tra i due canali, ogni singolo canale in effetti conduce meta del carico. Quindi, per il funzionamento monofonico ostruito dellamplific

16、atore si raccomanda lutilizzo di un carico di 8 ohm impedenza minima. ! ! ! ! ! ! ! ! POWER SWITCH The POWER switch is located on the front panel of the amplifier.

19、 comune consiglia laccensione dellamplificatore per ultimo e lo spegnimento per primo quando si accendono i vari componenti, per evitare linvio 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

20、distribution block or preamp switched outlet. When doing so make sure the switch is rated for the current required by the amplifier. OP E R A T I O N ! ! ! ! ! 5 INPUT CONFIGURATION SWITCH Mono / 2 Ch The amplifier operates in two-channel mode when the rear panel Mono/2 Ch switch is in the 2 Ch posi

21、tion. To use the amplifier in single channel, bridged mono applications, the front panel switch must be in the Mono position. When in Mono, the Channel 1 (+) and () inputs are connected to Channel 2 in reversed polarity, which inverts the Channel 2 output. Only the Channel 1 input is used, and the s

22、peaker is connected to the two positive (+) output terminals. For thermal considerations we do not recommend using less than a nominal eight ohm load on the amplifier when running it in bridged mono. Por consideraciones trmicas, no recomendamos el uso de una carga nominal menor de ocho ohmios cuando

23、 el amplificador est trabajando en el modo puente. Pour de raisons thermales, nous ne recommandons pas denvoyer lamplificateur, une charge de valeur nominale infrieure huit ohm, au moment du fonctionement en mode “mono.” Um thermische Strungen zu vermeiden, empfehlen wir in der mono Brckenschaltung

24、die minimale Last von 8 Ohm nicht zu unterschreiten. Per ragioni di natura termale non consigliamo luso di un carico nominale dellamplifiactore inferiore a 8 ohm nel caso di funzionamento monofonico ostruito. GROUND SWITCH Ground loops are characterized by a hum or buzz in the system and are caused

25、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 g

26、round 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.

27、 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

28、 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 f

29、ault. 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 an

30、y 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 a

31、nd 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 7 PC BOARD LAYOUT 8 SCHEMATIC DIAGRAM NOTES: Unless specified otherwise 1.
