OPPO Digital Model PRO900X - Manual (Page 10)

P A G E 1 0
The PRO900X HD Projection Display system is a high reso-
lution multiple signal format display monitor. It uses 7”
high performance liquid cooled CRTs. Each CRT has a 5”
active phosphor area and a 90 degree deflection angle. The
CRTs use high-resolution color corrected multi-layered
hybrid lens assemblies.
Horizontal scan frequency is from 15 to 50 KHz. Vertical
scan frequency is from 40 to 100 Hz. Video system signal
bandwidth is 35 MHz. The projected display diagonal size
(4:3 aspect ratio) is adjustable from 60” to 240”.
Supported signal formats include NTSC (3.58 and 4.43),
PAL (M,N,B, and G), VGA, SVGS, Mac II, and Grand Alliance
HDTV. Signal input options include 5 BNC connectors
(R,G,B,V,H), composite video, S-Video (Y-C), and an RS232
serial data port. The IR control format is addressable (0 -
99) for use with multiple unit installations. Each PRO900X
comes with a Universal customer remote control and a
service/alignment 5-function MBR3470 remote control.
From the factory, the PRO900X comes aligned for a 80”
wide display. The preset projection distance is 96 3/8” and
configured for a ceiling mount. You may customize the
setup to be floor or ceiling mounted and rear or front pro-
jected. Refer to the setup section before attempting an
installation.
The convergence system is a digital controlled analog sys-
tem with 10 signal format preset and 5 customer option
memory locations. The preset format memory locations
cannot be altered in the field. Each preset format has a
custom memory location to store customized setup data.
Each customized setup has a separated memory location
for each aspect ratio (4 X 3, letter box, compressed, and
16 X 9). You must set up and converge the system for each
aspect ratio that will be used. The five customer memory
locations are for signal formats that do not match the ten
factory preset signal formats. There is also the option to
copy the stored format data from one memory location to
another. This allows faster setup when several similar for-
mats are used. Internally generated signal patterns also
aid with setup of convergence. The internal pattern gener-
ator may sync from the internally preset signal formats or
it will sync from an external signal source. This is helpful
for on-site full convergence or just a touch up. You must
use the customer’s signal source to perform blanking and
phase adjustments.
The PRO900X cabinet is comprised of three pieces.
Removal of the case allows full maintenance access to the
systems electronic and mechanical assemblies. Front and
rear mounted IR detector assemblies allow almost no inter-
ference to IR control. There are adjustable (and removable)
feet on the bottom of the case.
