Tube-Tech CL 1B / 7 6 / Tube-Tech CL 1B
Enhanced VU-meter function:
Pressing
in the lower left side of the meter allows you to change between
three meter states.
L: Meter indicates left channel only
R: Meter indicates right channel only
L+R: Meter indicates both left and right channels
7 - Attack
The attack control determines how fast the compressor responds to an increase of the
input signal. The attack control is continuously variable from 0.5 to 300 milliseconds.
8 - Release
The release control determines how fast the compressor responds to a decrease of the
input signal. The release control is continuously variable from 0.05 to 10 seconds.
9 - Attack/Release Select
Three options are available
Fixed: Attack time: 1 msec
Release time: 50 msec
Manual: Attack time: from 0.5 msec to 300 msec
Release time: from 0.05 sec to 10 sec
Fix/man: This setting is mainly intended as an overall compression on a full mix or on
a sub-group mix. Combining the release times of Fixed and Manual modes, the
Fix/man mode facilitates an adaptive release function with fast constant attack and
release times for short peaks and a longer release times for longer peaks.
• Turn the Attack control counter-clockwise to increase the time before the release
control takes over
• Turn the Attack control clockwise to decrease the time before the release control
takes over
Notice that the Fix/man mode is in effect only when the peak-time is shorter than the
setting of the attack control. If the peak of signal is longer than the setting of the
attack control, or if the attack control is set fully counter-clockwise, it will respond as
in manual mode.
Overview & parameters
1 - In switch
CL 1B has two bypass functions. The IN switch activates/deactivates the processing,
but leaves the meter functions working.
2 - Gain
The gain control is used to compensate for the gain loss during compression. It is
placed after the gain-reduction section and therefore it has no influence on the
threshold setting. The gain control is continuously variable from off to +30 dB.
3 - Ratio
The ratio control varies the ratio by which the input signal is compressed. If the ratio
set to 2:1, and the input signal increases 10 dB, the output signal is only increased
by 5 db. The ratio control is continuously variable from 2:1 to 10:1.
4 - Threshold
When the signal is above the set threshold point, the compressor is activated and the
gain of any signal above the Threshold point is processed according to the ratio,
attack and release settings.
5/6 - Meter
Input: The VU-meter displays the input level.
Compression: The VU-meter displays the gain reduction. The meters neutral position is
at "0 VU", and the amount of compression is shown as a decrease in dB.
Output: The VU-meter displays the output level.
