All front panel controls are designed to be functional and uncomplicated.

Initial control settings:

1. Set VU switch to system level: +4dB is for standard analog signal level tracking

and mixing, +14dB is for digital mixing and mastering.

2. Set METERS switch to "In", and set CH1 and CH2 switches to "Bypass".

3. Set THRESHOLD controls off (fully counter-clockwise).

4. Set OUTPUT controls to unity gain position (12 o'clock noon).

5. Set ATTACK, RELEASE, and RATIO switches to straight up (12 o'clock noon).

The Liminator 2 has been designed so that this position is a useful starting point.

These switches can be adjusted to taste from this position.

6. Apply analog line level signals from your sources (mic pre-amp, EQ, console or

DAW). Adjust the output of each source to get nice hot levels coming into the

Liminator. VU meter readings should average around 0 and up into the red zone.

7. Set METERS switch to "GR". Set CH1 and CH2 switches to either T1 or T2.

For stereo operation, both channels should be set to same input transformer.

8. Slowly turn up the THRESHOLD controls, and observe gain reduction of signal

on the VU meters. Normal gain reduction is 2 to 6dB. Higher RATIO settings will

result in deeper compression.

9. While listening, adjust the OUTPUT controls to maintain appropriate levels back

into your signal path. To view the output levels on the VU meters, set METERS

switch to "Out". After "In" and "Out" levels have been checked, it is

recommended that the METERS switch be normally left in "GR" position.

10. Adjust ATTACK. This control represents the amount of time a compressor needs

to react to an input signal change. In general, fast settings are often used while

tracking percussive sounds (drums, piano, choppy rhythms). Mid settings are

good for voice, brass, acoustic guitar. Slow settings work well with strings, synth

pads, creamy guitar solos, and vocal chorus. On the stereo mix start with mid

settings and then, depending on the music, adjust towards fast or slow if needed.
