The ACTIVE switch operates a hard-bypass relay circuit to switch
the channels in and out of processing and a status LED indicates
that the channel is active.
The unit also switches to relay hard-bypass automatically in the
case of a power failure, either on the primary or secondary side of
the power supply, or when the unit is turned off at the POWER
switch.
If the T
RANSIENT
D
ESIGNER
is operated in the LINK mode (see 5),
channel one's (or three's) ACTIVE also switches channel two (or
four) in and out. Note that channel two's ACTIVE status-LED will
also follow channel one's ACTIVE status.
The SIGNAL-LED indicates an incoming signal with a level
exceeding -40 dB. In complex studio arrangements the LED indi-
cation helps to check if a signal actually arrives at the T
RANSIENT
D
ESIGNER
.
With the ATTACK control, the attack period of a signal can be
emphasised or attenuated by up to 15 dB. For detailed informa-
tion about the mode of operation of the ATTACK control please
read the section 'Tech Talk' on pages 7 and 8.
The ATTACK control circuitry incorporates two envelope gene-
rators. One follows the original curve while the second produces
an envelope with a slower attack period (Diagram 1, page 7).
