  • Page 6 The introduction of digitally controlled assignable systems in 1980 has allowed for their ergo- nomics to be continuously refi ned by user input and the Zeta refl ects this in its user interface. Fully assignable control means that any fader can control any channel or group. A dual layer design allows for single or dual path operation, and 2 Wild controls per fader allow allocation of assignable channel controls.
  • Page 7 Table-top or fl oor stand mounting. Comprehensive surround panning and monitoring. Flexible TFT screen-based meters with total user-confi gurability. Optional I/O expansion via a wide area interface such as MADI or Hydra, Calrec’s sophisticated audio networking system. Channel / Group Facilities All channels have 4-band EQ/Filters, Compressor/Limiter and Expander/Gate.
  • Page 8 PATHS AND PORTS On an analogue desk, the channel inputs are physical connections to the channel module or card. They are fi xed. Channel 1’s input is always channel 1’s input (even though it may be possible to control channel 1 from a different fader). Every channel will probably have both a mic and a line input, even though most will only use one of them at any one time.

  • Page 20 CHANNEL AND GROUP FADERS Channel and group paths are controlled by the console’s faders. Any fader can control any chan- nel or group path. Main paths have their own dedicated faders. Each fader can control two independent audio signal paths, named A and B. The A Pres 1 Mic 1 and B fader assign buttons are used to select either of the channel paths.
  • Page 21 Wild 1 or 2 for all selected fader paths. It is possible to assign the same control to Wilds 1and 2 for all fader paths by selecting ALL before pushing the required Assign panel rotary control. CLR will clear the selected Wild control from its assignment. CALREC Putting Sound in the Picture...
  • Page 22 VCA GROUPING VCA groups allow the audio level, CUT, AFL and PFL functions of several slave faders to be controlled from one master fader. A VCA group is made or edited by holding down the Assign Button (A or B) of the fader to be master and pressing the Assign buttons of faders to be added or removed as slaves.
  • Page 23 If the path’s fader is also a VCA mas- ter, the NULL LED operates only if the fader is in VCA interrogate mode thereby expos- ing the status of the slaved path. CALREC Putting Sound in the Picture...

  • Page 28 INPUT/OUTPUT CONTROLS Stereo and Surround Panning Stereo and surround panning is provided for channels and groups. Signals can be panned to both stereo groups and 5.1 outputs simultaneously. AFL can be heard in surround, post the pan controls, if the main outputs and monitoring are surround. The L-C-R pan allows the signal to be panned from left, through centre, to right.
  • Page 29 Input delay controls can be assigned to the Wild controls, and the wild’s push switch can be used to switch the delay in and out of the path. This function is enabled on the Options-Misc screen. Delay can also be assigned to Wild controls on the User-Chan screen. CALREC Putting Sound in the Picture...
  • Page 30 INPUT PORTS SCREEN In addition to the port and insert connection controls in the Input-Output section of the control surface, port connections for all inputs and outputs and the assignment of inserts can be set using the front end application. This screen allows patching of input sources to channel inputs, insert returns, direct inputs or to output ports.

  • Page 47 The OPTIONS-TX REH screen allows the condition switching for the sys- CANCEL tem to be set up. Functions can be set to be active, or not, in any of the Calrec Audio-England PSU FAIL three states. This can signifi cantly reduce the risk of human error, making the whole system a more robust, less stressful, user friendly environment for operators to work in.
  • Page 48 CONSOLE FUNCTIONS The console function buttons provide an easy way of clearing down console settings. These buttons are located above the meter selector controls. CHANNEL CLEAR - Clears the currently assigned channel from all settings apart from the port assignment. CHANNEL AUX CLEAR - Clears the Auxiliary send settings for the currently assigned channel.
  • Page 49 ZETA MEMORY SYSTEM calrec.com Putting Sound in the Picture...
  • Page 50 MEMORY CONTROLS 99 memories can be held in the Flash ROM for different console arrangements. In addition to this, the PC back-up can allow an unlimited number of memories, which can be restored into the Flash ROM as required. Memories can also be stored to external media, which can be useful for when several operators use the same console or when the console is used to broadcast many different weekly productions.
  • Page 51 Stacks can be saved to the hard disk or removable media as sessions. Selecting “Back Up Ses- sion” backs up the stack and all the memories in it. “Restore Session” allows previously backed up sessions to be restored. “Clear Stack” will remove all memories from the stack. CALREC Putting Sound in the Picture...
  • Page 52 MEMORY ISOLATION The Isolate screen allows some channel and group settings to be isolated from memory recall. This means their current settings will not be over-written when a different memory is loaded. The right side of the screen shows all fader paths. Paths can be selected from here or by pressing the fader assign button.
  • Page 53 A partial memory only loads those channels or components on the control surface that were se- lected using the partial memory selections. A partial memory load does not affect the currently assigned fader and the A/B layer assignments. CALREC Putting Sound in the Picture...
