System
The term 'system' encompasses the core, surface and connected I/O boxes. From the moment a signal enters a Hydra2
input it is in the system and remains there until it is passed out of a Hydra2 output.
System Logs
Various log files are maintained by different parts of the system. These log files can be collected and transferred to USB
memory for forwarding to Calrec Support in the event that detailed troubleshooting is required.
System Status Monitoring
Calrec's system for providing information and logs of any developing or occurring faults in the system.
T
Touch Display
Large TFT touchscreen used to operate the Summa surface, including patching, routing, processing and accessing de-
tailed system settings.
Tracks
Multi-function buses that can be patched to physical outputs. Used for such purposes as generating multiple interruptible
foldback feeds (IFB) or sending audio to multitrack recording devices.
U
User Memory
Recallable collection of settings which relate to a specific program type. Collections of user memories are collected with-
in Shows.
V
VCA Groups
The term VCA stands for Voltage Controlled Amplifier. A VCA group, unlike a group bus does not sum any audio.
Instead it allows a single fader to control the relative levels of any contributing paths. The controlling fader is known as
the master, the contributing paths are known as slaves. This maintains the relative levels of all paths in the group yet still
allows individual control where required.
