PAGE 2 (EXP) RATIO: The expander ratio (RTIO) can be adjusted from 1:1 (no expansion) to
1:20 (heavy expansion) in the following discrete steps: 1:1, 5:4, 4:3, 3:2,
5:3, 2:1, 3:1, 5:1, 7:1, 10:1, 20:1. The SW key functions as the expander
ON/OFF key.
ATTACK TIME: The expander attack time (ATCK) can be adjusted within a 200 µs to 1 ms
range, in 9 discrete steps (0.2 ms, 0.3 ms, 0.4 ms, 0.5 ms, 0.6 ms, 0.7 ms,
0.8 ms, 0.9 ms, 1 ms).
RELEASE TIME: The expander release time (RLSE) can be adjusted within a 10 ms through
10 s range, in discrete steps (10 ms, 20 ms, 30 ms, 50 ms, 100 ms, 200 ms,
300 ms, 500 ms, 1 s, 2 s, 3 s, 5 s, 10 s).
THRESHOLD: The expander threshold level (THRS) can be adjusted in 1 dB steps from
0 dB
FS
to –96 dB
