Equalizer Controls

The C50 Equalizer has eight Frequency Controls
which will raise or lower by 12dB, the amplitude of
the band of frequencies centered at the frequency
marked above the controls. The center frequencies
of these controls are at 25Hz, 50Hz, 100Hz, 200Hz,
400Hz, 1,000Hz, 2,500Hz and 10,000Hz. Both Left
and Right Channels are affected. At the center detent
or flat position of the controls, the tone circuit compo-
nents are removed from the signal path.
The illustration to the right shows the fundamental
frequency range of acoustical musical instruments and
the human voice. It also shows the range of adjustment
of frequencies for each of the Equalizer Controls of
the C50 at the +6dB and -6dB points.

Passthru

When the C50 is connected together with a McIntosh
Multichannel A/V Control Center or Surround Decod-
er and has the PASSTHRU MODE activated, it will
automatically turn-on when the A/V Control Center
or Surround Decoder is turned On. It will indicate on
the Front Panel Alphanumeric Display "PASSTHRU".
Refer to figure 74.
