The User Interface

3. COMPRESSION RATIO Control

This control adjusts the amount of gain reduction applied once the signal level exceeds the set THRESHOLD setting.

A setting of 1:1 means there is no change in level between input and output, which means no dynamics processing

will occur regardless of the THRESHOLD setting. The compression/limiting range of this control is from 1:1 (no

compression) up to ∞:1 (maximum limiting).

Rotating this control further clockwise, past the ∞:1 setting, increases compression into the INFINITY+ region, up to a

maximum of -1:1. Where a RATIO setting of ∞:1 essentially puts a "ceiling" on the output signal level and doesn't allow

any output signal level increase above threshold, negative compression goes further and allows the output signal level to

be reduced even beyond that of the set threshold. In other words, the louder the input signal level is above threshold, the

lower the output signal level will be, without hitting the "floor" of the THRESHOLD setting. This can be used for special

effect applications where the output level needs to be reduced below that of the input signal level. See the "RATIO"

graph in

'Compression Graphs' on page 6

including a negative compression curve using the -1:1 COMPRESSION RATIO setting.

4. OUTPUT GAIN Control

Adjust this control to compensate for the amount of gain lost during compression/limiting. Making up for lost gain with

this control makes it far easier to compare the processed signal against the unprocessed signal to determine if the

1. OVEREASY

This button sets the "knee" of the compressor/limiter. The knee

determines how abrupt or gradual the transition is between compression

and non-compression.

When disengaged, the 560A will operate as a hard knee compressor/

limiter – meaning the transition between compression and

non-compression is sharp or abrupt. This mode works well when a more

aggressively compressed signal is required.

When the OVEREASY button is engaged, the 560A will operate as

a soft knee compressor/limiter – meaning the transition between

compression and non-compression is gradual. This mode works well

when more subtle compression or limiting is required.

NOTE:

OVEREASY LED becomes active and lights when the signal level is in

the OverEasy region, which is just below the set threshold.

2. THRESHOLD Control

Adjust this knob to set the level at which compression or limiting will

begin. The range of this knob is from -40dBu (7.8mVRMS) to +20dBu

(7.8VRMS).
