Introduction

   
 

The Ampro 3400/3600 is equivalent to the Marquee 8500 or the Barco 808 projector. 105 Khz scan rate, RGB inputs, digital convergence, on screen menus, 8" EM focusing tubes, 1000 lumens, wired remote, etc. The Ampro 3400 is a late model version of the 3600.

The Ampro 4600 is a state of the art 9" set and cost $58K back in 1996-1998. Full 9" liquid coupled tubes with 110 Khz scan rate. A lot of adjustments on the convergence and picture parameters, this set is on par with the Marquee 9500LC, Barco 1209s, and apparently the Sony G90.

All Ampros require a serial computer interface or a custom Ampro wired or wireless remote to operate and set up. Without either, the projector is useless.

The reliability issues of the earlier Ampros (convergence drift, power supply issues and CRT socket failures) were more or less resolved with these later models. Also, the larger chassis of the 8 and 9” sets eliminated the cooling issues of the smaller 7” sets. This makes a higher end Ampro projector a great bargain compared to the more expensive sets like NEC or Barco. Personally I find the Ampro fleshtones to be very close to my favourite NEC sets.

Lots of parts are available on the used/surplus market for these Ampro sets, and as with the Electrohome and Barcos, an 8” set can be used as a backup chassis for the harder to find 9” sets, as most boards will swap right over between the sets.

To see how these projectors rank in relation to other projectors for use in a home theater environment see the Projector Rankings page.
