I nabbed one of these spiffy lil' guys for a mere SIX dollars on eBay recently! Enjoying the heck out of it on my 34" Sampo direct view CRT Smile

I don't happen to own any standard def CRT TVs with YPbPr at the moment, but the manual for the 1020 is kinda unclear on its support for SD. It's a transcoder, so I'm assuming it would have zero trouble passing any resolution from 480i to 1080i/1080p. HOWEVER, I was just curious if anyone here ever tried one of their old units with a '240p' game console (in case I bring it to a buddy's house sometime).

Also curious if, like the Audio Authority 9A60, it outputs Rec. 709 regardless of resolution, or if the X-Vue is also capable of Rec. 601. Not a big deal for this particular question, just curious Smile

I had one of those way back. Loved it. I can't remember testing 480i throught it but I did test 1080i and watched Pitch black with way more detail. I don't think it changes color space. It transcodes and adds the gamma bump. I did manage to run 1600x1200@106(?)Hz through it. Picture was good that was the top end of my Sony G520P's abilities. I also used it to add gamma for gaming on the PC

I use it for adding gamma to 31+ kHz sources on the VGA input of my 240p+480i / 640x480-1024x768 (or 720p and 1080i if your source outputs it) multiformat CRT monitor. For the 15kHz daughterboard, I actually have a X-Vue Gamma Boost connected! Heh. But yeah, don't really EVER use it for transcoding to component, just delicious gamma.

I still haven't figured out if it supports 15kHz, I will need to dig up an old Extron box that can force negative sync to find out once and for all. There are jumpers inside for things such as composite sync or HV sync, and sync polarity... but I am pretty sure composite sync output is forced to positive. I forget the deets, it's not pressing since I just use the X-Vue Gamma Boost for 15kHz but perhaps someday I will get to the bottom of this Razz

Not like there's really anyone out there who CARES, but I get quite a bit of enjoyment out of getting solid answers, heh - it just seems very unlikely that a mere transcoder would not support 480i/240p (ok, I could SOMEWHAT fathom one not handling 240p... but not really. Plenty of RGB *decoders* don't, but composite/svid to RGB or component is a whole diff ballgame than RGB <-> component transcoding). For science! Or rather, for super-outdated video gear that I am unreasonably obsessed with Razz

^ This “AV Stack” right here is just the tip of the iceberg, got drawers overflowing with all sorts of cables, adapters, converters, transcoders... then a separate room for the mounds of stuff I have on eBay / to eventually be listed on eBay.

Drowning in electricity! Wink

Also, this link below (not my site) shows the monitor I have, I implemented the RGB mod in the article except I opted for 4 BNC connectors instead. The thing is a beast! Dual subwoofers, I am scared to turn the volume much further than ~33%!

Does it count that under lockdown 2.0 I have 5 CRT TV's and 4 LCD displays in my living room facing "THE COMFEY CHAIR!"

Well, I have confirmed that it *can* work with 15kHz displays... but it’s incredibly finicky! I got the RGB output working on a vintage A2M6014 AppleColor RGB monitor, haha. Used it with a SEGA Saturn, a SCART to (15kHz) VGA adapter w/ an LM1881, and a VGA to DB15 adapter with various dipswitches on it lol

It seems like the thing must be outputting some funky sync levels that aren’t very widely compatible. Or... actually, just remembered - it might only output positive sync at 15kHz (and this seems to also apply to the sync on YPbPr output’s luma signal as well?)

I remember the sync issues. It could very well be positive sync. If I recall there are some jumpers inside the BOX1020 that may adjust that? It's been 14 ish years so don't quote me on that. I do remember many of the BARCO projector would only take a negative sync.
I aksi remember Juha - the creator of the BOX line of uhh... boxes had some info docs about jumpers.

I probably had all that stuff at one time but have had floods and a few clean ups around here since then so it may or may not still exist. I'll look around to see if I can find anything.

Open up the Box1020 and see if the board is labelled.

The users manual is still hosted here: http://www.curtpalme.com/docs/Box1020Instructions.pdf

Unfortunately that doesn't show the jumper settings.

I’ve messed with the jumper configurations a ton, heh (they are clearly labeled, as well. Three of em) - I double checked the manual and yeah, RGBS is apparently always positive. For the heck of it, I am gonna try chaining it before an Extron interface and see if the Gamma adjustment manages to work even when fed through a Extron interface. I remembered I also have an old scanline generator for emulation of 15kHz retro games on VGA displays, I believe the switch on it might also flip sync polarity as a byproduct?

Adventures in *extremely* outdated gear! lol. Though I do like the Gamma adjustment better on the 1020 than the “X-Vue Gamma Boost”/what became the HDFury GammaX. Would like to someday get my hands on the HDFury Nano GX or an old Crescendo unit, as well... never seen Crescendo stuff on eBay (which isn’t surprising, looks like it was some REAL nice gear!)

Crescendo systems was done by a great video engineer. He also made electrostatic loudspeakers on his kitchen island. His name was Kim. He died of a sudden heart attack.

http://www.curtpalme.com/forum/viewtopic.php?t=26075
Too bad the pictures are gone. It was great fun following along with him making those speakers.

I owned a bunch of his gear, it was good quality. I especially liked the RTC 2200. At one point I had 5 of them. Wish I still had them. I had one I used on my SONY D50 through a bunch of other gear for the gamma boost. Then I had a 6 disk DVD changer plugged into the component input for DVD box sets. Worked great.

You can certainly run gamma boost into an extron. My old setup was HDMI switch----HDFury1----RTC2200----Extron VSC 900D----32" CRT TV from the 480i component of the extron, RGBHV from Extron passthrough to SONY D50 and and RF modulator off of the composite of the Extron on CH3 going via coaxial cable to a 1985 14" CRT TV in the bedroom.

So you could watch any HDMI source on the 32" TV, the 120" D50 with Stewart Screen or head to bed and watch it on the 14" TV. Later I added a 37" LCD and the HDMI switcher had Matrix switching dual outputs so you could watch 2 things at once in bed. The audio from the switcher came out a set of RCA jacks to a 900MHz transmitter. There was a set of speakers in the bedroom with a separate volume control and 3 pairs of headphones so you could watch a movie and not disturb the neighbours. Also good for putting on a youtube story feed and walking out to the car to do some work while listening to the headphones or if nature called during a movie you put on the headphones and went to the shitter.
I miss that system.

Oh, I know all about Kim’s work - have lurked around here & admired it / even looked at the preserved Crescendo site on Archive.org. I can tell Kim was absolutely brilliant, lord what he woulda been doing nowadays... maybe some sorta insanely high pixel clock DACs / clever scalers / even-crazier speakers!

https://www.instagram.com/p/CMVJtzWlJ5g/?igshid=18l6hsbzmwst8

^ Here is a mere portion of my gear. I’ve been known to get wacky with DACs too, heh... such as combining sync and forcing 240p for emulated retro games! Next to that gear I have a 34” Multiformat CRT monitor with the 15kHz daughterboard modded for RGBS! http://mikejmoffitt.com/articles/0051-nettv-rgb.html Thanks to that guide there Smile

I literally have multiple stacks like that. LOL. They are fun aren't they?

Most certainly are! Until you get caught up experimenting & have a preposterously long silly chain of units and find yourself with audio but no video; wondering which device is giving you grief Wink

When I first got my DVDO VP50 it was set to video mute. I thought it got damamged in shipping. That was a fun 45 minutes trying to figure out what's going on.

Video Mute, that pesky switch.
