How to Operate
Power On and Off
The Red LED above the STANDBY/ON Push-button
lights to indicate the C22 is in Standby mode. Press
the STANDBY/ON Push-button on the Front Panel or
the (Green) Push-button on the Remote Control.
The C22 will go through a TUBE WARMUP (approx-
imately 16 seconds) with the Tubes glowing an amber
color. The LEDs around the INPUT and VOLUME
CONTROLS also become Rotational Active during
TUBE WARMUP. The Tubes will then glow green in
color and the Input Source and Volume Setting return
to the previous settings. Switch the C22 OFF by press-
ing the STANDBY/ON Push-button or the (Red)
Push-button on the Remote Control.
Note: For an explanation of the Remote Control
Push-button functions, refer to pages 9 and 10.
Source Selection
Select the desired source using the INPUT SELEC-
TOR Control on the Front Panel or press the INPUT
▲ or ▼ on the Remote Control. The illuminated
LEDs around the control indicate the selected source.
Volume Control
Rotate the Front Panel VOLUME Control or use the
VOLume ▲ (Up) or ▼ (Down) Push-buttons on the
Remote Control for the desired listening level. The
LEDs surrounding the VOLUME Control indicate the
current volume setting between the MINimum and
MAXimum setting of LEDs.
Mute Control
Press the INPUT/MUTE Control on the Front Panel
to Mute the Audio in the PREAMP OUTPUTS
(Loudspeakers) and Headphones. The C22 Front
Panel Volume Control LED at the 12 O’Clock Posi-
tion will flash On and Off while the Audio is muted.
Pressing the Mute Control a second time or adjusting
the Volume Control will un-mute the C22. The LED
Illumination of the Volume Control will return to its
previous setting.
Balance Control
Adjust the Balance by pressing the VOLUME/BAL-
ANCE Control. The Default Setting is equal amplifi-
cation for both channels, with illumination of the LED
at the center (12 o’clock) position of the Control. Ro-
tate the Control clockwise to increase the Right Chan-
nel Volume (LEDs on the right side of the BALANCE
Control will illuminate) or Rotate the Control counter-
clockwise to increase the Left Channel Volume (LEDs
on the left side of the BALANCE Control will illumi-
nate). About Four Seconds after the VOLUME/BAL-
ANCE Control is no longer being rotated to adjust the
Balance, the Control will return to being an adjustable
Volume Control for both channels. To check the cur-
rent Balance Setting, press the VOLUME/BALANCE
Control and the LEDs will indicate the current BAL-
ANCE Setting.
Mode Selector
The Front Panel MODE SELECTOR Control allows
the Left and Right Input Signals from the currently
selected source to be combined to outputs sent to the
Loudspeakers and Headphones.
Tone Switch
When the TONE Switch on the Front Panel is placed
in the ON position, the BASS and TREBLE Controls
become active. The OFF position of the TONE Switch
deactivates the BASS and TREBLE Controls and the
Tone Circuitry is totally bypassed for a flat response.
Bass Control
Rotate the BASS clockwise to emphasize the low
frequency content of the music. Likewise, rotate the
BASS counterclockwise to de-emphasize the low
frequency content of the music.
Treble Control
Rotate the TREBLE clockwise from the center (12
o’clock) position to emphasize the high frequency con-
tent of the music. Likewise, rotate the TREBLE coun-
terclockwise from the center position to de-emphasize
the high frequency content of the music.
Output 1 and 2
To switch Off the audio signal going to the Power
Amplifiers connected to the C22 Preamplifier Out-
puts, place the OUTPUT 1 and/or the OUTPUT 2
Rocker Switch in the OFF Position on the Front Panel.
When there is a Power Control Connection between
the C22 Power Control OUT 1 or OUT 2 and a Power
Amplifier(s), the Power Amplifier(s) will be switched
Off.
Phono Load Adjustments
There are Phono Load Adjustments for both types of
Phono Cartridges, Moving Coil (MC) and Moving
Magnet (MM). The resistive load for the MC Input
is selectable from 25 ohms to 1,000 ohms. The ca-
pacitive load for the MM Input is selectable from 50
picofarads to 350 picofarads.
Select the Phono Load setting using the Front Panel
MC or MM Control for the cartridge type connected
to the C22. Choose the value closest to the recom-
mended load value specified by the Phono Cartridge
Manufacturer.
