S
SDI (Serial Digital Interface)
Although SDI is primarily a means for encoding and transporting video signals, audio signals can also be encoded and
sent through in the ancillary data space. Certain Calrec SDI de-embedders can decode all groups and Dolby E encoded
audio for a maximum of 128 mono signals per SDI stream.
SFP (Small Form-Factor Pluggable)
SFP sockets accept a range of adaptors which provide different interface connections for copper or fibre connectivity.
This allows units fitted with SFP sockets to be customised to meet a range of requirements. All main network connections
in a Summa system make use of SFP sockets.
Show
A recallable collection settings as well as a way of organising User Memories which pertain to a specific program type.
Shows List
Shows can be loaded, saved and edited with the Touch Display in the Shows List view, which can be entered by tapping
the SHOWS LIST button in the top left of the Touch Display when in Active Show view.
Spill Faders
Allow control of legs of a multichannel signal. For example the overall level of 5.1 surround channels is controlled by
a single fader. By using the spill faders, components of the multichannel signal can be altered. If a spill fader is the
currently assigned fader, then processing can also be applied to that component using the assign panels. For a 5.1
channel the legs are broken into the following components: L/R (stereo), C (mono), LFE (mono), LsRs (Stereo).
SRC (Sample Rate Conversion)
A sample rate converter is by default switched in on each AES3 input in the event that an incoming external signal is at a
different sample rate or not synchronised to the same source as the system. It can be switched out if the incoming signal
is known to be synchronous.
Strip (Channel Strip)
Strip refers a vertical arrangement of controls on the surface. When the surface is in one of the strip modes (input/pan/
delay etc.) each pair of control cells becomes part of this strip arrangement.
Strip Mode
An operating mode of the surface. When one of the control modes (other than access) is selected, the control cells
above each fader are populated with mode specific controls for that fader.
Surface
The surface is the physical control surface for a Summa system containing the collection of faders, rotary controllers,
buttons, displays and touchscreen, allowing hands-on control of the audio signals. Also referred to as Console or Desk.
