3.5 Sub Amplifier Set-up
Place the Sub Amplifiers in their final set-up positions, allowing 8 inches at the
rear for tightening the speaker output connectors.
The power transformer in the Sub Amplifier is located at the front-center of the
unit. Ideally, a few feet should separate this area from components which
potentially could pick up hum. These include preamplifiers, turntables, and
interconnect cables. In terms of providing adequate airspace for cooling, a
good rule of thumb is to allow 6 inches above and 3 inches on each side of
the unit.
