DISCRIMINATOR DEFEAT FOR GATED INPUTS
Discriminator Defeat - If an input is used for a
line level source such as a tape player, then it
is not desireable to have it on the discriminator
bus. A line level input could raise the level of
the discriminator threshold to such an extent
that it would be very difficult to gate on another
gated input. For this reason, the Discriminator
Defeat has been provided. To defeat the
Discriminator function for an input, place a
jumper on the appropriate pins. When the
Discriminator has been defeated for a gated
input, it will no longer gate on in response to
an input signal. Instead, it must be Forced On
(see page 21). The figure below shows the de-
tails of jumper placement. As shipped from
the factory, the Discriminator is enabled (no
jumpers).
