3] Controls and Indicators

• DRIVE

This control adjusts the amount of signal sent to the side chain circuit and therefore the

amount of gain reduction applied. Think of it as a Threshold control as found on other

compressors. Clockwise rotation increases the amount of gain reduction.

• OUTPUT dB

Adjusts the post compression make up gain to bring the output level back up to the desired

level. Variable from 0dB to +15dB gain.

• ATTACK.

This switch has 3 positions. See Tips for Use for more info.

Slow – The attack time of the compressor = approx 70mS and varies slightly depending on

the amount of gain reduction. The attack time speeds up with greater gain reduction. This

setting is great for getting extra “front” on a percussive sound.

Auto – Attack time of the SOC 1.1 is totally dependant on the program material and the

amount of gain reduction occurring. This is perhaps the most “musical” mode when using

low Ratio settings and could also be named the “Classic Sound” setting.

Fast - The attack time of the compressor is 1mS, and also varies with program material.

Percussive signals will provide a further increase in speed, the SOC 1.1 will attack faster.

Recommended when using 10:1 or 20:1 Ratio setting under heavy gain reduction.

• RATIO

This control adjusts the change in gain reduction for a given change in input signal level. For

example, in position 5 a 5dB increase in input signal level will yield a 1dB increase in output

signal level, being a Ratio of 5:1. Because the SOC 1.1 has a soft knee characteristic, the

Ratio value selected is the ultimate achieved and will appear to be softer at threshold. Also

see page 7.
