Output Meters
The C500’s Output Meters indicate the Output Voltage
available at the MAIN and SPKR OUTPUT 1 & 2 Jacks to
drive Power Amplifiers. Refer to figure 70. The Meters are
calibrated in dB
(decibels) and re-
spond to all the
peaks contained in
the musical infor-
mation. They indi-
cate to an accuracy
of at least 95% of a
single cycle from a 2000Hz tone burst.
The Meter Electronic Circuitry “Time Stretches” the
Meter Drive Signal so the Meter Pointer pauses just long
enough for the human eye to see it and is followed by a
moderate decay rate.
The following C500 Operating Functions are performed us-
ing the supplied Remote Control.
Mono Mode
Press the MODE Push-button once to activate the Front
Panel Alphanumeric Display indicating the current mode
setting. Pressing the MODE Push-button a second time
while the display is indicating the “MONO (On or Off)”

mono signal at all Outputs except the Record Outputs. Re-
fer to figures 71 and 72.
Note: The C500 automatically stores into memory for each
