Extron electronic DMP 64 manual Group Masters, Group Members, Grouped Controls

Group Masters

There are 32 Group Masters that can each be configured to simultaneously control up to 16 group members. Group masters are configured in the DSP Configurator program and saved in the device. Working in emulate mode, group masters can be saved in a configuration file and pushed to the device upon connection.

A group master can either be a gain control or a mute control. Only one control type can be selected as group members for control by a group master. For example, a group master can be configured to control post-matrix gain levels, but not post-matrix gains plus input gain block. A group member can, however, be controlled by multiple group masters. It is recommended this feature be used cautiously, as overlapping membership can quickly become unmanageable.

Group master gain controls can send specific values, such as those sent by a fader control. Group master gain can also be set by increment/decrement. For information on using increment/decrement controls within the DSP Configurator software (see Tools on page 73).

Group Members

Once a group has been created, the group members, the individual controls that comprise the group, update to indicate they are now part of a group. Group members can be controlled individually, allowing for relative levels between group members to be fine‑tuned. Group member levels can also be set by a preset recall.

Grouped Controls

Grouping is convenient when multiple controls require muting at the same time or when multiple signal levels need to be increased or decreased simultaneously. For example, in a system with several audio outputs dedicated to a single room, the operator may want all outputs to change at the same rate and at the same time. The output 1 through 4 volume controls can be grouped into a master that controls the volume throughout the room.

For further flexibility, individual volume controls in the group can be set for an output level based on its use. When the group fader is moved, all four output control faders move in tandem while retaining their levels relative to each other.

Grouped faders move together at relative levels to the top or bottom of their travel (see Figure 46). If one fader reaches the limit of its travel first, it retains that position while the other faders continue to travel. When the grouped faders travel in the reverse direction, the fader that was at its limit reverts to its position relative to the other faders.

NOTE: If a block was previously muted when the group mute is activated, that block remains muted when the group mute is released.

TIP: When including a control in multiple groups, do so with care. Overlapping group membership can quickly become unmanageable. Use presets to set individual faders to known levels.
