TOSHIBA 41-inch CRT projection unit

41" CRT CUBE----P4130/P4135, P4140/P4145----
Choosing flexibility
The P4130/P4135 series cubes accept both NTSC, PAL & VGA input signals. The P4140/45 series cubes also accept a SVGA signal inputs.

Digital control
All controls, including picture size, position, white balance, convergence and linearity can be digitally adjusted with a remote control unit or by a personal computer with a RS-232C interface.
Convergence, the most complicated and time consuming of adjustment is tamed by using digital technology and is easier than purely analogue control or techniques.
Adjustment is done with eight horizontal and seven vertical points (NTSC, VGA and SVGA ; eight by eight points in PAL) that can be selected individually or in groups to achieve the best convenience.
The result is a precise set-up in minimal time.
High quality images free from flicker
Contour correction of the luminance and chrominance circuits regenerates vivid pictures, while RGB contributes to high picture quality.
When the cubes are used with TOSHIBA's TMP100 Video Wall processor, a double scanning system serves up flicker-free pictures in both NTSC and PAL modes on the P4130V.
It also improves the quality of magnified images.
An optional seamless screen that further enhances image quality is also available.
Easily reset control data
All user adjustments to the digital data controls can be effortlessly reset to the factory presets with a computer, bringing extra flexibility and convenience to frequent use.
Quick replacement of engine
Any problem requiring a change of engine is quickly and easily dealt with.
Release the quarter turn screws on the back of the cube and slide the engine out.
Three color temperature positions
A choice of three color temperature positions greatly add to user convenience:
6500K is the standard white color temperature;
3200K is ideal for use in TV studios;
the third position can be set to the user's preference.
Adaptable ABL
All cubes in a system can be linked by a system bus that offers unitary brightness control and a completely natural brightness balance.
