Set-up instructions

Input connections
Connect up to 8 input channels using either unbalanced (RCA) or balanced (XLR) cables. Channels are labeled 1 A, 2A, 3A, 4A and 1 B, 2B, 3B, 4B. A and B channels have separate power supplies. So, if you are connecting less than 8 channels, distribute them among A’s and B’s to take advantage of both power supplies. For example, with 4 channels, use 1 A, 1 B, 2A and 2B. Set the four toggle switches to UN BAL (unbalanced) or BAL (balanced) as appropriate. You can connect different source components, such as streamers and preamps, to both balanced and unbalanced inputs of a channel and switch between them using the toggles.

Output connections, trigger, and power
Connect up to 8 speakers using the corresponding output binding posts. Speaker wires can be terminated with “banana plugs” which are inserted, or stripped insulation (unscrew binding post cap, insert wire into hole on threaded shaft and tighten cap). Observe correct polarity(“+” red and “-” black).

The amplifier can be turned-on automatically by, for example, your preamp/processor by connecting a 12-volt trigger wire to TRIGGER IN (top right). You can use TRIGGER OUT to connect a “downstream” component such as another amplifier to also be turned-on automatically. Connect the power cord to AC INPUT (bottom right) and plug the other end into a 120-volt wall socket. (Customers in countries with 230-volt mains supplies need to order the 230-volt version of this amplifier, and provide their own power cord.) Right beneath the AC INPUT is a fuse receptacle. If it blows, replace this fuse only with one of the same rating. Set the rocker switch to ON to power-on the amplifier.

Operation

Vertical light on the front panel should be green. If it turns yellow, power- off, wait, then restart.
