is used, the Release Time cannot be set any less than 0.4 seconds to avoid noticeable pumping of the Input
Compressor/Limiter function.
The following list shows the possible settings for each Input Compressor/Limiter function control. Note: All dB
settings are dBu.
Compress: On/Off
Threshold: Off; –99½ dB to +25 dB in ½ dB steps
Ratio: 1:1, 2:1, 4:1, 8:1, 16:1, 32:1, ∞:1
Release Time: 0.2 (Fast compression only), 0.4, 0.6, 0.8, 1, 1.5, 2, 3, 4, 6, 8, 10, 12, 15, 20,
30 seconds
Compression: Fast/Slow
6.4.4 Auto Level Function
(Figure 6.12) Unlike the Input Compressor/Limiter function which is designed to handle sudden or transient jumps
in input level, the Auto Level function is designed to control long-term changes in signal level. Using it, the average
output level can be kept relatively constant over a longer time interval while transients are allowed to pass. This
feature creates a more natural sound with increased dynamic range.
