Krell Industries KSP7B owner manual C.Installation

MovingCoil Cartridges:' The KSP-7Bis shipped with the phono section gain set for moving coil cartridges and a load of 800 ohms. The load can be changed with a set of internal switches. To access these the top cover must be removedwith the supplied allen driver. At the left-rear of the unit there is a two-position toggle switch. In the factory-supplied position the switch lever is towards the rear panel of the unit. If you are using a movingcoil cartridge do not change the switch position. To adjust the input impedance load for different moving coils use the table below to find the optimum setting for your cartridge. Follow your dealer's or the manufacturer's

~recommendations first. You can also set the load using your sonic preferences as a guide. In general, lowering the impedance will make the high frequencies less prominent and the overall sound warmer. Higher

loads makethe overall sound more vivid and detailed. This is, of course, highly ~ubjective and very dependent on the cartridge in use.

The various load possibilities are detailed below:

all switches in the open position = 47,000 ohms

all	switches	open except 8 on		=	1,000	ohms
all	switches	open except 7 on		=	800	ohms
all	switches	open except 6 on		=	470	ohms
all	switches	open except 5 on		=	250	ohms
all	switches	open except 4 on		=	100 ohms
all	switches	open except 3	on	=	47	ohms
all	switches	open except 2	on	=	25	ohms
all	switches	open except I	on	=	10 ohms
all	switches	on		=	5	ohms

Moving Magnet Cartridges: To set the Phono section for Moving Magnet operation, with the impedance adjusted to 47,000 ohms, set the phono gain switch towards the front of the preamplifier. This lowers the gain of the phono section to compensate for the higher output of moving magnet cartridges. Set all impedanceswitches for both channels to off.

C.INSTALLATION

1. Cautions!

Note: These are important points of which you always should be aware. They are presented before the actual installation procedures, should you not

read through the manual entirely.

a.Do not connect the power cord into the ACmains before completing the "Installation" section!

b.The power amplifier(s) should always be turned off while making connections.
