PROCESSING OVERVIEW - SIGNAL FLOW
Introduction
The audio-processing features in EQ Station is made in the highest quality possible, with internal 48bit processing giving a
large headroom for EQ changes, and a noise floor well below the AD/DA performance, no matter how extreme EQ settings
you require. The internal headroom also makes it literally impossible to have internal overloads, and the Peak Limiter on
the Outputs will make sure that no nasty digital noises ever occur in your speakers.
Processing overview
For each channel in the EQ Station (no matter configuration) you always have the same processing capabilities. The
processing is always available, and you will therefore never have to make the choice of e.g. running Graphic EQ OR
Parametric EQ - in other words you will never run out of DSP-power on an EQ Station.
• Parametric EQ.
Lo and Hi filters can be set to shelving or parametric
type. Bands 1-4 selectable between Parametric or Notch.
• Graphic EQ.
Four different Graphic EQ types are available:
- TC1128
- Classic 960 Narrow-Q / Classic 960 Broad-Q
- Classic 27
On the following page you will find a more elaborate
explanation of these types.
The processing runs in a fixed signal flow:
Note
• All processing is always available. Degrading of quality will not appear at any time no matter how much of the processing
features are activated.
• The order between the processing blocks cannot be changed.
• Dynamic EQ.
Two modes are available:
- Three band Dynamic EQ operating in the full frequency
range.
- Parametric Dynamic Two Band EQ (Paradyn) with
individual frequency selection.
• Delay, 600ms.
Individual Delay on each channel for alignment according
to position.
• Peak Limiter
High quality Output Limiter, primarily for protection of
speaker systems. The Peak Limiter is always active.
