The Architectural series was designed for installations in board and conference rooms where a compact, easily hidden interface could be coupled to local CRT monitors or LCD Panels.  It has the advantage of converting unbalanced stereo laptop audio, to Balanced Stereo outputs.   This is an excellent tool for connecting Laptops, PCs etc., to external mixers and monitors cleanly, without any distortion or hum pickup.  

These units were removed from a corporate Board room installation, both are in VVG condition.

If you are interesested in the RGB 440, we'd be happy to answer any questions you might have prior to making a desision.

Additional information from the Extron Manual:
 

The Extron RGB 440 is a 300 MHz universal analog computer-video and audio interface designed to connect workstations and PCs to large screen display/audio systems. With an Extron MBC (monitor breakout cable) or an MBC buffer, the computer’s local monitor may be used while the RGB/BNC output goes to a large screen. Analog input can be from VGA, Mac, XGA, XGA-2, Quadra, Sun, SGI, or another source.

The RGB 440 may be mounted under, or on the side, of a table or desk using the included Under Desk mount.

Descriptions of front and rear panel LEDs, controls and connectors follow. T

A. Power LED - On = power and video sync pulses are present.

B. Audio input connector - 3.5 mm, stereo jack (tip = L, ring = R, sleeve = ground).

C. Analog video input connector - Input connector for MBC buffer, LBC, or MBC cable from computer.

D. MBC Power output connector - Provides power for MBC buffer if required.

E. Termination switch - Provides 75 ohms video input termination if no local monitor is used.

F. H-Shift control - Shifts the image horizontally on remote display device.

G. Sync processing DIP switches Serr = Serration pulses enabled when up. DDSP = Digital Display Sync Processing enabled when up.

H. Power input connector - The input voltage range is 12 to 24 volts AC or DC.

I. RGB BNC output connectors, Sync BNC output connectors

K. Audio output connector

Sync processing switches

Video projectors of different types or from different manufacturers may have slightly different sync pulse requirements. Sync processing DIP switches on the RGB 440 front panel (G) enable the user to modify output sync by enabling or disabling vertical sync serration pulses and enabling or disabling Digital DisplaySync Processing (DDSP). The Sync processing switch module contains two DIP switches labeled SERR (left switch) and DDSP (right switch). The Serr switch in the up position (enabled) will result in the removal of serration pulses from the output composite sync signal (does not affect SOG, H or V outputs). The DDSP switch in the up position (enabled) provides Digital Display Sync Processing, which may be required for digital display devices which exhibit an unstable display. With DDSP enabled, the H Shift control (F) on the front panel is defeated.
