Note that once AUTO time has been selected, the attack control becomes
inoperative.

.6 GAIN control
Because compression is a gain reducing process, the output signal level can often
be lost. The GAIN control is provided to restore this output to normal operating
point, and provides a calibrated range of ±20dB.
The facility of gain loss provided by this control can be used, when required, to
restore the compression to a point lower than the input signal (For example, when
connecting this output to a high sensitivity input on a following piece of
equipment).
10
.7 BYPASS switch
The BYPASS switch enables you to bypass quickly all functions of the
DPR-402
by
connecting the output directly to the input. When the switch is pressed, and the
light is on, all
DPR-402
functions are present on the output signal. When the
switch is out, all facilities are bypassed.
It should be noted that in the bypass mode, the input is still connected to all of the
DPR-402
circuitry, so that all of the required facilities can be selected and set up.
This, in conjunction with the OUTPUT METER and INPUT SWITCH, provides a
powerful tool for comparing processed signals prior to operating the bypass switch
and going 'on-air'.
A further feature of this illuminated switch is to allow coding of each particular
channel with a specific number or letter. By removing the lens-cap with a small
screwdriver or your fingernail, an appropriate symbol can be fitted. This will have
particular advantages in situations where more than one
DPR-402
is fitted into a
control rack.
10
.8 MODE switch
This control switch reconfigures the compressor to insert the built-in filters into its
side chains, so that gain reduction only occurs when certain frequencies are
present in the input signal.
For normal compression, this switch will always be in the 'compress' position.
