Cascade Audio Outputs

The "Cascade Audio Outputs" enable you to connect additional amplifiers to your preamplifier's output. Connection is accomplished with standard RCA interconnect cables. The outputs are not buffered; to daisy chain more than five Niles amplifiers you will need a Niles AVDA-3 buffered distribution amplifier. A single AVDA-3 enables you to daisy chain five amplifiers from each of three outputs. This allows 15 SI-1260 power amplifiers to be fed from the same master preamplifier. If your pre- amplifier has a vacuum tube output stage, you must use a Niles AVDA-3 to drive more than one SI-1260.
