STEREO
When the LINK push-button is engaged and the two channels, A and B, set to approximately the
same values, GAIN control on both channels will be the same to preserve stereo balance, levels
normally being controlled by the channel with the higher signal level.
DUCKING
When the LINK push-button is
engaged, the signal passing
through channel A, may be used
to control the amplitude of
channel B. For example, the
level of music through channel A can be controlled by speech on channel B, i.e. reducing the music
level to make a "speech-over" announcement.
METERS
Two LED METERS are provided, OUTPUT LEVEL and GAIN REDUCTION.
These are switched between channel A and channel B on the central METER SELECT push-button.
OUTPUT LEVEL indicates the actual output level in dBu.
The GREEN segments cover the range from -10 to +10 dBu.
The YELLOW segments cover the range from +10 to +20 dBu and the RED segment, +22 dBu and
above which is regarded as overload.
REDUCTION is calibrated in dB covering the range 1 to 22 dB, reading backwards.
This meter indicates the amount of actual reduction taking place and therefore is a valuable point of
reference indicating the operation point of the 5043.
