CALIBRATION
Guide / Instructions
This calibration allows you to set the amount of air added when the air circuit is engaged. It
also allows you to match the left and right side air boosts.
One thing to note is that the gain adjustment also changes the corner frequency slightly.
Lowering the amount of air boost also lowers the frequency slightly and increases the
resonance at that frequency. This means that as you increase the air boost, you get more top
end extension but slightly less resonance boost and the frequency of that boost goes up. For
this reason, lowering the gain can also make the boost slightly more noticeable and adding
more gain will actually create a more linear response overall, even though it is adding more
top end extension to the boost.
1: With the HG-2 still at the unity settings described earlier, feed it a 12khz tone at -20db and note the
reading on the meter.
Step 3: ‘Air’ boost
2: Engage the air circuit and not the meter reading.
3: If the sides are not matched when air is engaged or you woud like to adjust the amount of boost,
adjust the trimmers below.

CALIBRATION
Guide / Instructions
This calibration allows you to adjust the left / right balance of the saturaiton circuits as well as
adjust how hard the signal hits the stage.
1: With the HG-2 still at the unity setting, feed it 1khz at -20 and note the meter reading.
Step 4: Parallel saturation
2: Set the Parallel saturation knob to 12 o'clock and make sure the “alt tube” button is disengaged.
3: Engage the saturaiton circuit and note the meter reading.
4: As needed, adjust the trimmers below until the two sides match.
5: When the main circuit is matched, engage the ”alt tube” button and repeat the adjustments with the
appropriate trimmers.
