•
Split Mode: Enabling Split Mode will unlock access to Channel 2, which is mapped to Output
2. When Split Mode is activated, Channel 2 setting will be unlinked from Channel 1 and can
be set to completely different values.
•
Set to Flat: Click this to "start over" when creating your curve, this button will reset all
frequency values to the flat default. Only the levels will be affected.
•
Configuration: Toggle between two band configurations: parallel filters, which is most
common in graphic equalizers, and series/cascading filters, which is more common in true
parametric equalizers.
•
Input High Pass Filter: Each channel has a default high-pass filter, configurable 10Hz to
80Hz. Note that the filter is always active. Setting to 10Hz effectively removes the filter from
the signal.
•
Bands 1 and 10 Shape: The lowest and highest bands, 1 and 10, can be toggled from a
standard "peaking" filter shape to a "shelving" shape. A low shelf cuts all frequencies to the
left of the selected frequency. A high shelf cuts all frequencies to the right of the selected
frequency.
•
Reset to Default: This option will reset all of the equalizer settings to default including levels,
frequencies, Q, and other options.
Master Volume & Trim
This block contains controls for independent input trim settings and a master Output control, with
decibel readouts.
Limiter
We've included a clipping limiter to eliminate unwanted clipping that occurs under extreme settings.
•
Enable: Click this to enable the limiter per channel.
•
Look-Ahead: By default, the limiter uses a lookahead delay. Click this button to disable the
lookahead delay.
•
Link Channels: When "linked" the Limiter will use whichever channel has the highest levels.
Otherwise, Channel 1 and 2 operate separately.
Noise Gate
We've included a noise gate to tame excess noise in your signal path.
•
Enable: Click this to enable the noise gate per channel, either for a single channel or both.
•
Threshold: By default, the noise gate threshold is set to -100dB, but can be set to a more
aggressive -60dB for very noisy signals.
•
Gate Source: Select the input source for the noise gate, either Channel 1 or Channel 2.
