TARDIS
The small cupboard at the back of the room is called the TARDIS.
Sound Rack
This diagram shows the important cable connections in the back of the rack as of April 2025.
1 - Aux In
This input makes it easy to feed a stereo signal (e.g. from a phone or laptop) into the main speakers.
The knob allows you to adjust the volume of the sound.
The switch swaps this Aux from either being sent to all of the Amps or routing it to a subsection of the amps, designed for allowing you to play house music to the foyer while still preparing for the show in the annex.
All the things on this panel are connected to and processed by Tesira in the same rack.
2 - Tesira
The Tesiraforte AVB VI is used to provide speaker-specific EQs, feedback suppression and most importantly limiters.
Connecting it by USB to a computer enables use of it as an audio interface, currently setup with 8 channels of audio connected 1-1 with the outputs to the amps
| Number | Input | Output |
|---|---|---|
| 1-2 | From patch panel 1A-1B | Amp 1A-1B |
| 3-4 | From patch panel 2A-2B | Amp 2A-2B |
| 5-8 | From patch panel 3A-3D | Amp 3A-3D |
| 9-10 | Aux | N/A |
| 11-12 | From patch panel Tesira mics 11-12 | N/A |
3 - Amps / Small store / Ties / other Patch
This Patch Bay connects outputs and ties to the small store patch panel, the Amps and miscellaneous ties around the annex. There are several different modes in use.
| Number | Out (A, top) | In (B, bottom) | Mode |
|---|---|---|---|
| 1-4 | Small store mics 1-4 | Small store mics 9-12 | Thru |
| 5-8 | Small store mics 5-8 | Small store ties 1-4 | Thru |
| 9-14 | Tie 1-6 (From desk) | Tie 1-6 (To stageboxes) | Normal |
| 15-16 | Booth 1-2 | Tesira inputs 11-12 | Thru |
| 17 | Return 1 | Amp 1A | Half Normal |
| 18 | Return 2 | Amp 1B | Half Normal |
| 19 | Return 3 | Amp 2A | Half Normal |
| 20 | Return 4 | Amp 2B | Half Normal |
| 21 | Return 5 | Amp 3A | Half Normal |
| 22 | Return 6 | Amp 3B | Half Normal |
| 23 | Return 7 | Amp 3C | Half Normal |
| 24 | Return 8 | Amp 3D | Half Normal |
Notes:
- Tesira inputs 11-12 are configured to be a set of auto mixing mic inputs
- Return 1-8 are loomed with network cables, not to be confused with tie 1-6.
- Amps go through Tesira after this patch panel and before the amps.
4 - Mic Line Patch Panel
This allows you to route the Mic lines from the stage left and right patch panels to specific input lines in the multicore loom to the desk.
This panel uses the normal mode
