Control Linking; Identifying Linked Faders; Link Features - Calrec SUMMA User Manual

CONTROL LINKING

Paths can be linked, meaning that if a parameter is altered for one linked path it will also be altered for all other
linked paths for which the parameter is relevant. Memory isolation is also included in the control link.
Link buttons are available for all Summa faders, positioned between the talkback and access buttons. To add a path to
the link, simply push LINK. To add a fader on a different surface layer to the link group, use the layer select buttons 1–6
to access the desired layer, then push the path's LINK button.
To link a group of sequential paths, simultaneously push the LINK buttons at each end of the group, e.g. simultaneously
pushing LINK buttons for fader one and four adds faders one, two, three and four to the link.

Identifying Linked Faders

All linked paths can be identified by their illuminated fader LINK buttons. If link is active on a layer other that the current
accessed layer, the LINK CLEAR button will pulse to indicate that the link is still active.

Link Features

• Parameter changes across linked paths are made relatively, for example, if the gain of one linked path is increased
from 0 dB to 5 dB, a linked path with an original gain of 5 dB will be increased to 10 dB.
• Frequency controls are altered 'musically', for example, if one EQ frequency control is increased from 5kHz to 10 kHz,
i.e one octave, the corresponding frequency control for a linked path starting at 7 kHz will also be increased by one
octave to 14 kHz.
• If a path is cloned and then added to the link group, all its clones will also be linked.
For reasons of safety and usability some features are not included in linking:
• Port patching
• PFL/AFL
• Phantom power
• VCA masters can not be linked
