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.) |

mco NNECTINC i THE 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,
