Quick Start Guide
On your sound system, mute your monitors and then using balanced TRS cables, connect your LiN 76 to your mixing bus or patch bay. Set all controls to full counter-clockwise position, and all pushbuttons deselected or in the off position make sure that no ratios are selected. Set the OFF button to the deseleted (vu meter will turn on) position, and apply power. Unmute the monitors, and verify that signal is passing to and from the unit. Set the Input, Output, Attack and Release controls to about 12 o’clock, select Ratio 4, and press the GR pushbutton. Increase the Input until the meter is deflecting a few dB. Again, verify signal is passing through the unit. At this point that the unit is functioning correctly. If you would like the compressor to compress more increase the input knob. This will allow more signal into the compressor and cause the compressor to react more. If you would like the compressor to compress more with the same amount of signal input, increase the ratio. Ratios can be selected by pressing one button at a time OR combinations of different buttons at the same time.
All Button Mode
By pressing in all 4 buttons you active what is referred to as “all button” mode. This “secret mode” changes the ratio to roughly 20:1. It also changes the bias of the circuit and the way that the knobs interact with each other. The unit will become much more aggressive with its reaction knee becoming more like a plateau than a gentle curve and will have a more aggressive dirty tone that sounds incredible on aggressive drums. The attack will become very punchy with a gooey “sucking” sound on the release.
Favorite Setting
While there is no proper way to use a compressor (please experiment and get creative!) there are certain settings that we do personally suggest for certain sources. The most popular use would be vocals and we find that a relatively mild input signal of about 36- 30 should cause gentle compression for vocals, creating a thickening effect without crushing the audio. Then use the output control to bring the vocals back up to the orginal volume level. Setting the attack to roughly 9 o’clock and the release to about 3 o’clock with give it a natural sound without sounding artificial.
Meter Calibration
Making sure that the meter returns to zero is important to the compressors functionality. This is controlled the the mater calibration set screw on the back of the unit. Set the meter to GR and make sure that no ratios are selected by pressing in any ratio button just enough that all 4 pop out. Then using a flathead screwdriver, rotate the screw on the rear panel until the needle rests on 0. Voila! Meter calibrated.
- Power Button: turns the unit off. When gr, +4 or +8 are selected, the unit is on.
- Input: Sets the threshold and controls the level at which the compressor starts compressing. Louder signal will require less input to trigger the same amount of compression than softer sounds.
- Output: Applies makeup gain to compressed signal to compensate for signal lost during compression
- Attack : Controls the amount of time it takes for the unit to react to an incoming signal. Continuously variable from 20uS to 800uS
- Release: Controls the speed at which the compressor releases the compressed signal. Continuously variable 50mS to 1200mS
- Ratio: Controls the amount of compression applied (Yes, it does all-buttons-in-mode). The higher the ratio, the more compression is applied for the same amount of signal inputted once compression is triggered.
- VU Meter: Displays units selected by Meter Mode.
- Meter Mode: Selector switches GR meters the amount of gain reduction applied (+4 meters output level at 0 with +4dB output; +8 meters output level at 0 with +8dB output)
- AC Adapter Input: ONLY use the supplied 12VAC to power this unit.
- Meter Calibration: Use this control to adjust the 0 resting point when no compression is being applied.
- TRS Output: Balanced line-level output
- TRS Input: Balanced line-level input.
Note: For proper performance, balanced TRS must be used for all inputs and outputs.
