If your preampliÞer has RCA out- puts, it can be connected to the ampli- Þer inputs as shown. The ampliÞer will boost the preampliÞer's output, up to a level suitable for driving speakers.

This diagram also shows how the Voltage Source outputs connect to the input posts of your speakers. (The Current Source outputs can be used instead.)

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 may damage your ampliÞer or speakers.
