CONNECTIONS

PASSIVE BI-AMPING

The X-AS100 has both 'Loop Out' connections and a Mono/Stereo button to allow flexible use in various Bi-amping combinations. In these combinations the X-AS100 is used in conjunction with either another X-AS100 or compatible amplifiers with a gain of 33 such as the X-A50 or X-A200 monoblocs from Musical Fidelity. A pair of bi-wireable speakers is required (and the bi-wire links must be removed) so that one amplifer channel can drive the treble unit (tweeter) and another channel can drive the bass unit (woofer). Please refer to the two examples below.

Example 1. Two X-AS100s

In this example, one X-AS100 is used to drive the left speaker whilst a second X-AS100 drives the right speaker.

The Right output of your preamp is connected to the first X-AS100 to either the Left or Right Line Input (it does not matter which). The Mono/Stereo Button is then pressed in for Mono operation. The Right Louspeaker output is now wired to the Bass unit terminals of the first speaker with a normal speaker wire pair. The Left Loudspeaker output is now wired to the Treble unit terminals of the first speaker, again, using a normal pair of speaker wires. This process is now repeated for the other X-AS100. Again the Mono/Stereo button must be pressed in for mono operation. The Left output of the preamp is connected to either of the Line level inputs of the second X-AS100. Then as before one channel of the X-AS100 drives the bass unit of the second speaker and the other channel drives the treble unit. See diagram below:
