ES ECON NECTING A TURNTABLE

The C C-80 accepts two turntables.

The PHONO

1 turntable can

carry either an MM or an MC cartridge; the PHONO 2 turntable -

is MM only. The front oanel's PHONO

rotary switch selects the

turniasie. The lefimost position selects PHONO

2, which requires

an MM cartridge of 47k ohms 220 pf impedance. The (Ne

positions to the right are all for PHONO

1: a choice of 3 MM and

2 MC settings is offered.

On the rear panel next to the turntable jacks is the Phono Gain

Switch—a small red button. Use this switch to refine volume

control with high output level ¢ cartridges, Press the button in to

lower the output signa! by 10 decibels; press again to release the

button and return

the out iB signal to normal

Plug each turntable's output cords into the appropriate PHONO

jacks. Connect the turntabie s ground wire to the Gnd terminal.

(This normally produces minimum hum, but in some cases

disconnecting the ground wire gives better results.)

POWER ANP

When using a oo

power amplifier for each channel, make

the alternate hookup in Fig. 1 . This allows vou to run ordinary

stereo amplifiers (those without inverting pre outs) monauraliy.

Power amplifiers' supply capacity limits their bass response.

When a strong bass note enters both channels of the power amp,

total demand for power is high. The PRE OUT INVERT jacks can

solve this Med

The hookup shown in Fig. 2. operates the

power amp's left and right channels out of phase, greatly

reducing the demand on the power supply and in many cases

dramatically improving bass reproduction. Be sure lo reverse

connections to one speaker as shown, to bring output back into

phase,
