Connections Using CAN Link

The Evolution Two brings a new convenience to the operation of monaural pream- plifiers, using a sophisticated, reliable control system called a controller area net- work (CAN). Using CAN Link, any number of preamplifier channels may be linked for multichannel playback. CAN Link enables all linked preamplifier channels to be controlled from any single linked preamplifier channel in the system.

To Connect Multiple Evolution Two

Preamplifiers via CAN Link:

After the power supply chassis is connected to the preamplifier chassis with the

12-pin DC cable:

1.Connect one RJ-45 connector from either CAN Link connector (45) on the back panel of any preamplifier chassis (1) to either CAN Link connector on any other preamplifier chassis. The two preamplifier channels that are connected are now linked.

2.Repeat Step 1 for each additional preamplifier channel you want to link. For more information on linked preamplifier channels, see Appendix: CAN Link and Multiple Evolution Two Preamplifiers, on page 51.
