Check for porper polarity

Speaker cables are a critical link between your loudspeakers and your new A-100 Power Amplifi er. Pay close attention to the polarity on the rear panel binding posts. It is critically important that you match plus and minus (red and black) of the A-100 Power Amplifi er to the plus and minus of your speaker. Carefully observe the polarity. The plus or red terminal of the A-100 Power Amplifi er must eventually be tied to the plus or red terminal of your loudspeaker. The A-100 Power Amplifi er is a non- inverting amplifi er design meaning it is in phase with the input signal.

Be careful when connecting a subwoofer

Turn the rear panel master power switch on

Most subwoofers have low level inputs only, as in an RCA or XLR connector. Some subwoofers have high level inputs where the output

of the amplifi er can be connected as an input to the subwoofer. Generally there is no problem. In a few rare instances there may be a problem, which will show itself as problematic if the amp’s protection comes on after hooking up the sub. REL subwoofers and some Sunfi re subwoofers can be problematic. Please check with the factory or your dealer if you encounter these subwoofers or any problems.

The binding posts, on the rear panel of the A-100 Power Amplifi er will accept either spade or banana type connectors. To use a spade or forked connector, simply unscrew the binding post, place the tongs

of the spade over the threaded binding post and tighten the outer barrel of the binding post. It is permissible to us a wrench to tighten the binding post down.

The banana style connectors should be inserted into the center hole on the rear of the binding post. To use banana connectors, you will need to remove the plastic insert blocking it. To do this, unscrew the binding post almost all the way open. Look inside the small hole on the shaft of the binding post and note the small pin that prevents the outer cap of the binding post from being removed. Using a small metal pointed tool, push the metal pin until it is removed. This will allow you to unscrew the outer binding post cap all the way and remove the plastic center pin.

Turn your equipment back on. Make sure everything is powered up properly with the A-100 Power Amplifi er between the AC receptacle and your AV equipment.

Make sure the preamplifi er or surround processor that is feeding the A-100 Power Amplifi er is turned on fi rst. Then, turn the rear panel power switch on the A-100 Power Amplifi er to on and power up the A-100 Power Amplifi er. There is a normal 2 second delay for the amplifi er once powered up.
