BASIC INSTALLATION

LOCATION

Place the KSAon a firm level surface away from excessive dirt or moisture.

When using custom racks or cabinetry, keep in mind the weight and ventilation requirements for these amplifiers. Ideally the amplifier should be placed as close to the speakers as possible. It is preferable to run long balanced interconnect cables to the amplifier and keep speaker cable length to a minimum. Speaker cable adds impedance to the load the amplifier must drive, regardless of the cable's gauge. All KRELLamplifiers will drive the lowest impedances with ease, but when impedance is added due to long

cable lengths, amplifier power is literally wasted in driving the cable. Long

speaker cables reduce the maximum power that can be delivered to the speakers.

REMOTE TURN-ON INSTALLATION

Someinstallations do not have adequate space or arrangement flexibility for the amplifier to be placed near the speakers. To allow for this, the KSA ¯ amplifiers can be turned On or Offfrom a room other than the listening room.

of amplifier placement is

NOTE:Whenset-up for remote turn-on, the front panel power switch will not operate, nor will the power switch on the remote control. The meter switches on the front panel and remote are not affected and will operate normally.

NOTE: Remember to keep speaker cable lengths to a minimum.
