6. Threshold control- Adjusts the threshold level for the Compressor section. SKC (Smart Knee Control) is
applied to the audio signal when a maximum of 10dB above the set threshold is reached. Above 10dB, a
hard knee compression is applied
7. Threshold LED- Shows the state of the input signal in relation to the threshold level. If the input signal
falls below the set threshold level the left "-" LED will light up and the signal will not be compressed. If the
input signal rises above the set threshold level, this signal will be compressed and the SKC level will be
shown by the middle "0" LED
8. Ratio control- The ratio between the input and output level of audio signals exceeding the set threshold
9. Attack control- Determines how fast the compressor reacts to audio signals that will exceed the set
threshold
10. Release control- Determines how fast the compressor returns to unity gain when the audio signal falls
below the threshold level
11. Auto switch- Allows the attack and release controls to be automatically set based on the audio signal
12. Output gain control- Adjusts the output signal by a maximum of 20dB to recover the level lost during
compression
13. SC external switch- Separates the connection between the audio input and the sidechain path but
allows an external signal through the Sidechain return jack
14. SC Monitor Switch- Connects the sidechain control signal to the audio output, muting the audio input
and monitoring the sidechain signal being returned via external signal processors
15. Sidechain filter switch- Activates a low-cut filter in the sidechain path, eliminating unwanted noise
generated by low frequencies
16. Smart switch- Hard knee mode will be converted into SKC (Smart Knee Control) mode for musically
transparent compression
17. Bypass switch- Turns off the corresponding channel, to make an A/B comparison of the processed and
unprocessed signal
18. Input/output meter switch- Switches to the input level meter when turned on; switches to the output
level meter when turned off
19. Input/output level meter- Displays the input or output level
20. Gain reduction meter- Displays the amount of gain reduction
Limiter
21. Threshold control- Controls the level of the Limiter
22. Limiter LED- Lights up when the Limiter function is activated
