Electronics rack
The electronics rack contains 10 TDT Zbus devices chassis, each containing two TDT series 3 devices. Furthermore it contains the Field coil amplifier and the Femto LockinAmplifier as part of the head tracking electronics.
The zBus Monitor program has control functions for the optical bus. It shows all the connected zBus chassis and the TDT devices that are installed in each chassis. It also shows the version number of the installed firmware on the devices.
The following table shows all the zBus chassis from top to bottom, with the installed devices.
| Chassis | Front left | Front right | Back |
|---|---|---|---|
| Zbus | MS2 Monitor speaker | <empty> | |
| Zbus | PA5 Attenuator | PA5 Attenuator | F05 optibit bus #1 |
| Zbus | PA5 Attenuator | PA5 Attenuator | F05 optibit bus #2 |
| Zbus | SA1 Speaker amplifier | SA1 Speaker amplifier | |

LED system
The LED system consists of a cabinet inside the sound boot with a PLC system (programmable logic controller). The PLC can independently switch 256 channels. The channels connect to a two color LEDs (red and green) that are mounted on the speaker. The PLC cabinet has two test buttons that can light all LEDs at once. The PLC system (Panasonic FP2) consists of a PLC with several IO units and is can be programmed by via a special USB cable.
