Line Output Channels

There are four mono line output channels. Controls and processing blocks, identical for each output channel, are described in the following sections.

Loudness (LOUD)

The loudness processor, when inserted, applies a filter compensation curve to the signal in an inverse relationship to the output volume control setting. The higher the gain setting, the less loudness compensation is applied. Generally, as volume is lowered, perception of certain frequencies is progressively diminished, returning to a more flat response as volume is increased. Loudness boosts those diminished frequencies to the highest degree at low volume levels, decreasing the boost as volume increases.

The bypass button is red when engaged (loudness control defeated), and gray when disengaged (loudness control active).

When bypassed, the graph displays the current filter curve as a dotted line. When bypass is disengaged, the current filter curve is displayed as a solid line.

Figure 39. Loudness Dialog Window

The Loudness dialog window contains the following elements:

Graph — Displays the compensation curve applied to the signal. These curves are read-only, and are not adjustable from the graph.

Loudness Compensation slider — From a center zero-point, the user can slide to the left for less loudness compensation (filter curve is reduced), or to the right for more (filter curve is increased). The slider position is translated into a dB value, displayed in

the compensation readout box contained in the Advanced Calibration section. The slider has a 48 dB (±24 dB) range.

Advanced Calibration — The advanced calibration box provides a value that corresponds to the position of the compensation adjustment slider. The SPL box displays the summed value of the slider and the preceding trim control.
