Input Connection Considerations

Whenever possible, keep preamplifier level audio cables away from electrical power cords by at least a few inches. It’s more important with amplifiers as the AC power cords are carrying much more current than other source and preamplifier components, which means there is a larger degree of noise or “hum” potential with the amplifier power cord in close proximity.

Output Connection Considerations

The output connectors provided on each channel of the UPA-2 are standard “binding post” speaker connectors with industry standard spacing. These are sometimes called 5-way binding posts because of the many ways in which the speaker wire can connect into the posts. The posts can accept bare wire, spade terminals, and dual or single banana connectors. Spade connections or banana plugs ensure a simple, solid fit in the terminal whereas bare wire may be awkward when the terminal is screwed down to compress the wire into place. Keep in mind that if you use “dual banana” plugs and “stack” them, you will be creating a parallel connection. For more details on series and parallel connections, see pages 15-16.

It is important to observe polarity so that the speaker wire connects to the red and black terminals on the amplifier and the corresponding terminals at the speaker. Also make sure that the positive speaker wires do not touch the negative speaker wires, or any chassis metal. This will cause a short circuit and activate the protection circuitry.

Connection Tips for Superior Sound

Before setting up your new system, please consider the following:

•Always make sure the UPA-2 is turned off before making or changing ANY connections.

•Whenever possible, route the power cords away from the signal cables or speaker wires to prevent any hum or interference heard in the speakers.

•Many RCA type patch cords can be a very tight fit and there is usually a preferred method of getting them off. Some have to be removed with a twisting action. Be gentle or you may damage the jacks of your UPA-2, the cables themselves, or other components.

•Many audiophile signal cables are intended to be hooked up in one direction. If this is the case, the cables will be marked with arrows the direction of signal flow.

•It is usual for the right channel RCA patch cord plugs to be red and the left channel connections

to be white, grey, or black (depending on the cable brand). RCA connectors that are gold will be designated with a colored band to designate the channel.
