“Reset Biases” – When a bias handle is moved this button lights half-bright to indicate that the
bias curve is non-null. A single press nulls the bias control handles for the currently active and
visible bias curve; using shift-click will reset the bias handles for both the LF and HF sections of
the currently active bias curve. A small red or yellow dot indicates that the non-selected bias
curve is non-null.
“Log / Lin Select” – Switches the display between logarithmic (LF) and linear (HF) modes.
Quick Start Guide for the DeHisser Section
1. Click on the IN button of the DeHisser.
2. Set Cutoff to the desired frequency between 3kHz and 15kHz..
3. Set the Reduction to 0dB. Lower slowly to the point where hiss reduction is acceptable.
Quick Start Guide for the Oxford DeNoiser (Simple Broad-band Noise Removal)
1. Leave in Auto mode. For simple broad-band noise reduction, set the Reduction slider of the
Remove section to around -12dB.
2. Adjust the Thresh slider to find the right balance between being too low (not enough noise is
removed) and too high (too much audio is also removed). You may find it easier to listen to Diff
mode, where you are listening to what has been removed. The idea is to have the maximum
amount of noise and hiss in this signal, with the minimum amount of original signal.
3. See if adjusting the Smooth control gives a more pleasing result.
4. If necessary, adjust the Tune control to reduce “twinklies” (musical noise).
5. Set the Reduction to 0dB, and then very slowly lower the control until the amount of noise
reduction is acceptable.
6. You can use the Makeup control in the removal section to do some critical comparison.. After
noise reduction, the level of the signal may be significantly lower. If this is so, you can use the
Makeup control to add gain to make it closer to the original. Then you can use the master IN
button to do glitch-less comparison of with and without noise-reduction, comparing like-level
with like-level.
