Time values depending on the rectifiers
Although the Attack and Release times can be considered fixed intervals, the con-
trol-time behavior and operating mode of the tubes is very different depending on the
music. That is why these values should not be considered absolute values. The following
chart should give an overview of the dependence of the control times of the input signal
and the chosen Rectifier, with the same preset (OFF) of Side Chain EQ. Attack and Release
were switched in sequence, together, from Fast (A + R position 1) to Slow (A + R position
6). The times were measured with an input signal of frequency 10 kHz.
