OverEasy® Switch: OverEasy® provides a smooth transition from the com- pressor’s linear region to the compressed region. This smooth transition greatly reduces compression artifacts and allows faster attack times and higher com- pression ratios while still maintaining the natural characteristics of the signal. The switch lights to indicate OverEasy® processing is enabled. Figure 1 below illustrates the the input/output relationships for OverEasy® operation. Figure 2 illustrates the same for hard knee operation. When conventional hard knee pro- cessing is desired, disable the OverEasy® function

THRESHOLD LEDs: These three LEDs indicate the relationship of the input signal level to the threshold of compression. The green “below” (-) LED is on when the signal is below threshold and the red “above” (+) LED is on when the signal is above threshold. When the 262 is switched to OverEasy® mode, the amber “O” LED is on when the signal is in the OverEasy® region (See Figure 1).

COMPRESSION RATIO Control: This control selects the ratio between input and output levels for signals above the threshold. Rotate this control clockwise to increase the amount of compression from 1:1 (no compression) up to infini- ty:1 (no increase in output level, regardless of input level increases above threshold); further clockwise rotation increases compression into the INFINI- TY+™ region, up to a maximum of -1:1 (i.e., a 1dB increase in input level above threshold causes a 1dB decrease in output level). In the INFINITY+™ region, the 262 inverts the program dynamics for special effects. Figures 1 and 2 illustrate input/output slopes corresponding to various compressor/limiter ratio settings.

OUTPUT GAIN Control: Adjust this control to vary the amount of fixed gain (up to ±20 dB) in the 262’s output amplifier stage. The OUTPUT GAIN control does not interact with the threshold of compression.

GAIN REDUCTION Meter: This 8-segment LED meter indicates the amount of gain reduction due to compression/limiting, ranging from 0 to 30 dB.

STEREO COUPLE Switch and LED: This switch changes the 262 from two independent compressors into a stereo compressor. In Stereo mode, Channel 1
