3. CONTROL ELEMENTS
YourCLE 4.0 presents with four channels. Each channel is equipped with the same control elements: 3 push-button
switches, 4 rotary controls and 17 LEDs. Youcan operate in stereo mode via pressing the Couple switch. The details
please refer to following content.
1. Threshold Control for Compressor Section
With this control you will adjust the threshold level in the Compressor.The range is varied from -40dBu to +20dBu. When
a signal exceed the set threshold by 10dB maximum the SKC will be applied, while above such level signal will be processed
with hard knee compression.

2. Ratio Control
The ratio in between input and output level signals above the set threshold is determined by this control. When the
SKC is applied such ratio is only expressed for the signals exceeding the set threshold more than 10dB. The range
of control of the ratio varies from 1:1 to :1.
3. Output Gain Control
Youcan increase or decrease the output signal by a maximum of 20dB. IN such a way you can recover a level lost
during the compression process.
5. Smart Switch
Ahard knee compression is turned into SKC by mean of this switch. If you wish to get a compression that is quite
inaudible use the SKC mode through the Smart switch.
4. Bypass Switch
Push this switch and you will deactivate the corresponding channel. Youcan also use the bypass switch to make an A/B
comparison in between processed and unprocessed signal.
6. Meter Switch for input / output
When this switch is ON the Meter will read the output level. When the switch is OFF,the Meter will read the input
level.
7. Level Meter for Input / Output
Youcan adjust the operating level by mean of the Operating Level Switch and choose -10dBV or +4dBu. Consequently
the Meter will be the Input or Output Level with a range from -24dB to +18dB.
8. Meter for Gain Reduction
The gain reduction will be shown by this Meter with a range of 1 to 30dB.
