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.
