CONNECTING YOUR AMPLIFIER

Setting up your amplifiers is rather easy.

1.Connect all source components (turntable, CD, Tuner, Tape DAT, etc.) to your preamplifier.

2.Connect the interconnects from the output of the preamplifier or switching center to the RCA input on the top rear of the amplifiers. IF your source has a truly BALANCED output, connect TO the XLR input and select the balanced input on the switch. If using a standard UNBALANCED source, select and use the unbalanced RCA connector. This amplifier will not function properly if you are using the wrong input for your application. The XLR inputs signals are transformer balanced and floating. Pinout is Pin 1: Ground; Pin 2: POSITIVE (+); Pin 3: NEGATIVE (-). The XLR input can be driven by balanced or unbalanced outputs on preamps and is particularly useful if ground loops and hum is a problem or long lines are being driven. Pin 1 is ground which can be cut for a true isolated output which can sometimes cure some ground loops. If using an unbalanced device to drive the transformer-coupled XLR input, you may GROUND Pin 3, but do not float it. Both legs of the trannie must be connected to something when you are using the XLR input.

3.Be sure to select XLR or RCA input depending on which one you are using. No tunes will get into the amplifier if you have the wrong input selected.

4.Connect the hot or "+" speaker cable to the red binding post and the common or "-" speaker cable to the white binding post (See diagram 2). Ensure that the other end of the cable is connected correctly to the speaker. Tighten the binding posts by hand. If you use a nut-driver or wrench, do not over-tighten the posts or you may break them.

5.Ensure that the "mains" switch on the front panel is DOWN in the "off" or "0" position and the OPERATE / STANDBY switch is also down in the STANDBY mode.

6.Turn on Preamplifier and all the source components you plan to use.

7.Plug amplifier into wall outlet.

8.Switch the black right-most mains power switch UP to the ON position and allow the amplifier a minute or so to 'warm up'. The blinking LED will indicate that the amplifier is in STANDBY / SOFT-START mode.

9.Engage the soft-start switch UP to the OPERATE position. The blinking standby LED will extinguish.

10.Turn up the volume on your preamp and enjoy the glorious tunes. If you don't hear tunes, make sure you do not have the amplifiers MUTED... hit that MUTE switch.

11.After your listening session, if you wish to leave the amplifier in the energy-saving and 'EVER-WARM' STANDBY mode, engage the OPERATE/STANDBY switch to the STANDBY position. The standby blinking LED will remind you that the amplifier is in STANDBY mode.
