INSTALLATION The 9130 Amplifier is supplied in either a 17” Black Version, or a 19” Silver Version. The 19” model RACKMOUNTING has rackmounting holes provided for installation in equipment racks. The holes are on standard EIA spacings. Due to conflict with adjacent equipment, it may be advisable to remove the four rubber feet from the bottom of the unit. The feet may be removed from the outside, with no dis-assembly of the chassis necessary. VENTILATION/ The 9130 Amplifier can produce considerab

All output connections to the amplifier must be performed with the amplifier off! OUTPUTS The left and right audio outputs from the amplifier are via standard 5-way type, 3/4” spacing, binding posts. Connect these binding posts to the loudspeakers. The amplifier’s binding posts will accept single or dual banana plugs, spade lugs, pin plugs, or bare wires. If using bare wires, it is recommended that the ends of the wire be tinned with solder so that no stray strands can cause a short circuit to t

CIRCUIT HIGHLIGHTS The 9130 employs a single ended, current source driven, differential input stage. This stage is connected to the rest of the circuitry through a balanced push-pull current mirror system. A combination current mirror and bias multiplier drive the final output stage driver emitter followers. Special linearizing techniques are used that dramatically reduce harmonic distortion. The final output stage uses two multiple lateral MOSFET’s (Metal Oxide Semiconductor Field Effect Transi

The 9130 Amplifier is equipped with a simple means to adjust the AC line voltage rating for 100, 120 CHANGING LINE or 230 volts AC, 50/60 Hz. The configuration is labelled above the power cord connector. If the amplifier VOLTAGE RATING will be used in a location that requires a different line voltage, use the following procedure to change the configuration. Review the modification instructions before attempting this procedure. If any doubts exist about one’s ability to change the line voltage, i

Apply power to the amplifier, and allow the unit to thermally stabilize for about three minutes. (If 4) using an analog meter, and the meter reads backwards, temporarily remove power and reverse the meter leads.) Again referring to the diagram, locate the trimmer potentiometer labelled Pl for the left channel, 5) or Pl 01 for the right channel. (NOTE: Do not confuse these trimmers with those labelled P2 and P102: these are for distortion control and require specialized test equipment to adjust.)

SPECIAL NOTE ON VIDEO CABLE “GROUNDS”: As mentioned above, the ground conductor of cable service and antenna feeds should be connected to earth ground. Often, however, due to long feed lengths, especially in apartment distribution systems, this ground will be of poor quality and could be a source of noise. This interference is usually characterized by a high frequency noise, rather than a hum or a buzz. If such interference is experienced, a separate earth ground connection should be made from t
