he T461 is a 1RU high 19-inch rack mount unit, with four line level stereo RCA pairs as inputs and one line level RCA pair as output. It has an RS232 input and a 240 volt IEC mains connector. A 12-volt power output can power the T460R (and any other attached equipment. All connections are on the rear, and on the front are four LED channel indicators and screw-driver adjustable pre-scaler trim pots, one for each stereo pair.
Recent software can permanently allocate channel 4 as a "microphone" channel, which can be turned ON from a T460R before the projector turns on (e.g. at the start of a lecture, and the volume set using the T460R volume control keys. Pressing ON again turns on the projector and program audio (from the lower three channels is mixed with the microphone (on channel 4) allowing the lecturer to comment on the program on the screen. A dummy channel on the T460R is able to be allocated for microphone level control while the projector is running, allowing dynamic level changes. Pressing OFF turns off the projector, but allows the microphone to still be active until the OFF is pressed again.
An option for the T461 adds 8 outputs (-R8). It has eight relay contact outputs which can be used to control screen up/down functions, projector "dipper", room lighting pre-set selects, etc. The relays are also controlled via the RS232 secondary link from the T460R to the T461. The relay states are indicated by LEDs on the front panel of the T461. Control options include control of a C-Bus or a Dynalite lighting control system, or Quest, Kramer or Extron video switching systems.
