Attack Sustain Link | Sound Performance Lab 9842 instruction

The ATTACK control circuitry incorporates two envelope genera- tors. One follows the original curve while the second produces an envelope with a slower attack period (Diagram 1, page 7).

The difference (Diagram 2, page 7) 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 using the ATTACK control please refer to pages 12ff.

The SUSTAIN control increases or reduces the level of the sustain portion of a signal by up to 24 dB. For detailed information about the mode of operation of the sustain control please read the 'Tech Talk' section on pages 8 and 9.

Two envelope generators work in the SUSTAIN control circuitry, too. Again an envelope follower pursues the original envelope and adapts optimally to the curve of sustain. This second gene- rator produces an envelope with extended sustain (Diagram 4, page 8). The difference between both envelopes is then used to calculate the voltage controlling the VCA, though as with the ATTACK circuitry, the enhancement ceases at the end of the signal being processed.

Sustain amplitude is increased for positive SUSTAIN settings and reduced for negative settings. For detailed information about using the SUSTAIN control please refer to pages 12ff.

When processing stereo material, the LINK function should be switched on so that the linked channels produce the same degree of gain change, regardless of any difference in levels of the two channels. This is necessary to maintain a coherent and stable stereo image.

The front panel controls, including the ACTIVE switch of channel

1 or 3, function as the master controls in LINK mode.
