LINK ADJUST:
The “LINK ADJ” is used to calibrate two Chimera™units for stereo use, however it also effects the
amplification of the signal level within the internal sidechain.
Note: Over amplification of the sidechain signal may result in compression artifacts and / or
oscillation of the internal sidechain (will be evident when in “HF” mode and “PEAK” knob is turned
fully clockwise). The “LINK ADJ” can be adjusted by inserting a small phillips head screw driver
into the hole located on the front panel above the “LINK ADJ” text and following the instructions
below. To calibrate the internal sidechain to factory default settings for mono use, please follow
step 1 below. To calibrate the internal sidechain for both mono & stereo use, please follow both
Steps 1 & 2 below.
Step 1: Sidechain Calibration:
1) Turn the “LINK ADJ” screw fully clockwise.
2) Set the “G/R / VU” toggle switch to the “G/R” position.
3) Set “FLAT / HF” toggle switch to the “FLAT” position.
4) Set “OFF / LINK” toggle switch to the “OFF” position.
5) Set the “Peak” knob to the fully counterclockwise “0” position.
6) Send a 1KHz test tone to the unit and adjust the “GAIN” knob so that the signal reads -10db in
your DAW.
7) Turn the “PEAK” knob until the VU meter indicates -4db of compression (DAW should now read
approx. -14db)
8) Slowly turn the “LINK ADJ” screw counterclockwise until the VU meter indicates only -1db of
compression (DAW should now read approx. -11db)
Note: If compression artifacts / oscillation still occur when “HF” mode is engaged and the Peak
knob is turned fully clockwise, simply continue to turn the “LINK ADJ” screw counterclockwise
until compression artifacts cease. The goal is to have the “Link ADJ” screw turned as fully
clockwise as possible but just to the point where compression artifacts do not occur. Generally,
following the steps above for a 3db drop will produce this result.
Step 2: Stereo Calibration (Two Chimera units required):
1) Set the “G/R / VU” toggle switch to the “G/R” position on both units.
2) Set “FLAT / HF” toggle switch to the “FLAT” position on both units.
3) Set “OFF / LINK” toggle switch to the “OFF” position on both units.
4) Set the “PEAK” knob to the fully counterclockwise “0” position on both units.
5) Send a 1KHz test tone to both units and adjust the “GAIN” knobs on both units so that the signals
both read -10db in your DAW.
6) Turn the “PEAK” knobs on both units until both VU meters indicate -4db of compression (DAW
should now ready approx. -14db on both channels)
7) Turn the “OFF / LINK” toggle switch on both units to the “LINK” position.
8) Determine which of the two units is indicating more gain reduction on the VU meters. On only the
unit that is indicating more gain reduction, slowly turn the “LINK ADJ” screw counterclockwise on
that unit until both units indicate the same amount of gain reduction on the VU meters.
9) The units are now calibrated for stereo use.
