Speaker-level audio outputs From: Amplifier outputs To: Speaker input posts

If your preamplifier has RCA out- puts, it can be connected to the ampli- fier inputs as shown. The amplifier will boost the preamplifier'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 can be used instead, as shown on the next page).

Make sure that the posi-

wires, or any chassis metal.

This will cause a short circuit and may

damage your amplifier or speakers.
