However, when the VCA Master Faders are used, more than one VCA Master can combine to alter the level of a single input channel. What’s more, the VCA Master Fader, because it affects the input channel directly, can also alter that channel’s post-Fader output to any of the eight auxiliary mixing busses, something not possible with the conventional Group Master Faders.

In the case of the input modules, where the standard monaural module and stereo modules are similar, we have used the same feature number where the features are identical. Where the features are not identical, we have used an “S” suffix. For example, feature [4] is the 48V phantom power switch in both the monaural and the stereo input module

NOTE: In some applications, it is preferable to have the PRE position be Pre-Fader & Post-EQ rather than Pre- Fader & Pre EQ. The PM4000 is equipped with internal switches that make it easy to change the “Pre” of each AUX send in this manner. This functional modification can be performed on a channel-by-channel basis, and for any or all AUX sends within each channel. Refer to the OPTION

2.1.2. The Stereo Input Module The PM4000 comes with at least four stereo input modules, located in near the master section. More of these stereo modules can be ordered in lieu of the monaural input modules.
