PAGE 2 (COMP) RATIO: The compressor ratio (RTIO) can be adjusted from 1:1 (no compression) to
1:20 (heavy compression) in the following discrete steps: 1:1, 4:5, 3:4, 2:3,
3:5, 1:2, 1:3, 1:5, 1:7, 1:10, 1:20. The SW key functions as the compressor
ON/OFF key.
ATTACK TIME: The compressor attack time (ATCK) can be adjusted within a 200 µs to
20 ms range, in 9 discrete steps (0.2 ms, 0.3 ms, 0.5 ms, 1 ms, 2 ms, 3 ms,
5 ms, 10 ms, 20 ms).
RELEASE TIME: The compressor release time (RLSE) can be adjusted within a 10 ms to
10 s range, in 13 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 compressor threshold level (THRS) can be adjusted in 1 dB steps from
0 dB
FS
to –96 dB
