D. BASIC INSTALLATION AND

OPERATION

1. Place the unit on a firm level surface free from exces-

sive dirt or moisture..The KSL-2 is not particularly hum
sensitive, therefore other components can be placed on or

around the KSL-2. Care should be taken however if the
optional phono board is installed. Motors, power
supplies and some digital devices can induce hum
through the phono board.

2. Plug the AC cord into the receptacle on the back of the
unit. Plug the remaining end into the wall AC receptacle.
The pilot LED will illuminate.

NOTE: While the KSL-2 has superb regulation and does

not require a dedicated AC circuit, we strongly advise
against any connections through extension cords or mul­tiple AC adaptors. High quality 15 amp line conditioners
or grounded ~C strips are acceptable.

NOTE: The KSL-2 is designed to be left ON at all times.
OPTIONAL PHONO OPERATION

The KSL-2 has an optional phono board available. The
phono board is swichable f6r Moving magnet and Mov-

ing coil phono cartridges. Should the phon, o. board be
ordered at a later dat,~, a full description ot installation
and operation is supplied with the phono board.

1. With phono board install,ed, set the input impedance

loading of the phono cartridge to the load impedance
closest to the manufacturer’s specification. The unit ,

comes factory set,to 100 ohms in the Moving coil switch
position. FolIow the instructions in the KSL-2 Phono

Manual for exact set-up description should changes be
necessary.
