NOTES ON INSTALLATION
Be sure the volume controls are fully counterclockwise
before making connections to the KRS-IA; also, the power
amplifier(s) should be off while making connections. Place
all power amps, C.D. players or other power supplies a
reasonable distance from the KRS-IA as they might induce
hum into the phono section. Our custom RCA connectors are
made to very exact standards. Connectors of lesser quality
can damage them or function improperly. Please check with
your dealer or the factory as you could cause damage to
your system or jeopardize your warranty.
PHONO SECTION SET UP
The KRS-IA is shipped with the phono section set up for a
moving coil cartridge and loaded to 100 ohms. The loading
can be changed with a set of internal switches. To access
these switches the top cover of the preamps must be removed
with the supplied allen driver. The phono section is located
on the left side of the unit, as viewed from the front. In
the middle rear of the phono PC board, which is mounted on
standoffs, there is an 8 position switch.
The various load possibilities are detailed below:
all switches in the open position =
