Compressor Bypass: Bypasses the compressor in the signal chain.
Make-up Gain: Compression usually results in an overall reduction of level. The
Make-up Gain knob allows you to restore the pre-compression level. You can adjust
Make-up Gain from -0 dB to +18 dB.
Attack: Attack sets the speed at which the compressor acts on the input signal. A
slow attack time (fully clockwise) allows the beginning component of a signal
(commonly referred to as the initial transient) to pass through, uncompressed,
whereas a fast attack time (fully counterclockwise) triggers compression immediately
when a signal exceeds the threshold. The compressor attack time ranges from 0.5 ms
(Fast) to 10 ms (Slow).
Release: Sets the release of the compressor, which is the time the compressor takes
to return the gain reduction back to zero (no gain reduction) after the signal level
crosses below the compression threshold. The compressor release time ranges from
40 ms (Fast) to 500 ms (Slow).
Power User Tip: Very short release times can produce a choppy or “jittery” sound,
especially when compressing instruments that have a lot of low-frequency
components, such as bass guitar. Very long release times can result in an
overcompressed, or “squashed,” sound. All ranges of release can be useful, however,
and you should experiment to become familiar with different possibilities.
2.3 EQ Controls
EQ Bypass: This switch bypasses the EQ. When both the compressor and the EQ are
bypassed, the ADL 700 acts as a tube preamplifier only.
EQ>Compressor: When the EQ>Compressor switch is engaged, it places the EQ
before the compressor in the signal path. When it is disengaged, the signal passes
through the compressor before passing through the EQ.
Power User Tip: Placing the compressor before the EQ allows you to make dramatic
changes to the EQ settings without needing to alter the compressor setting.
However, if you place the EQ before the compressor, you can better control different
frequencies, achieving a more natural response. The ADL 700 provides the flexibility
to choose which signal flow is right for your application at any given time.
