Microphone / Projection System
A TARDIS is equipped with an internal audio and projection system. The Audio Units are combination speaker/microphones that are found on the Control Consoles. A telescoping microphone can also extend out of the console on a flexible "goose-neck" arm. This microphone is primarily used for communicating with other "local" timeships within the Vortex. A TARDIS's loudspeaker system (otherwise known at the intercom) allows someone in a control room to broadcast their voice throughout all parts of a TARDIS's interior. These audio systems can be used in conjunction with the Scanner and other communications equipment such as the Voice Integrator.
The Control Room Recorder uses a sample image locator to make holographic, video, and audio recordings of anything in the Control Room.
The Control room has Trans-Temporal Projector that creates a hologram-like image with accompanying sound from the Audio Units. The Projector can be used for playing messages (such as T-Mail from Gallifrey) or displaying star charts across the ceiling. The holographic projector also displays a humanoid image for the medical bay's Automatic Diagnostic Terminal when in voice interface mode. The image presented is usually that of the operator Time Lord but, upon request, the TARDIS can use the memory store to find other avatars. The projector can be used to play pre-recorded messages if it receives the right signal or if an object containing a recognizable code is brought into the TARDIS.
A fully functional Scanner has an external speaker/microphone that is controlled by the Audio Units. It is possible to project a holographic image of the operator's face on the exterior of the TARDIS and the operator can also trigger a loud external klaxon.
