Transient Designer
9
The ON button operates a hard-bypass relay circuit to switch
the channels in and out of processing. The illuminated button
indicates that the channel is active.
The unit 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 Transient Designer operates in LINK mode (see 5), channel
one's ON also switches channel two in and out. Note that channel
two's ON button illumination follows channel one's ON status in
LINK mode.
The SIGNAL-LED indicates incoming signals with a level excee-
ding -40 dB. In complex studio arrangements the LED indication
helps to check if a signal actually arrives at the Transient Designer.
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 6, 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 6).
The difference (Diagram 2, page 6) between these envelopes
results in a voltage that controls the VCA, boosting the transient
for a period equal to the duration of the original transient. The
amplitude of the attack is increased, if positive ATTACK values are
set, while negative ATTACK values reduce the level of the attack
transient. For detailed information about the ATTACK control
please refer to pages 11ff.
