I have Pioneer DVL-909 and I can’t fugue out how to enable the CX on analogue it was easy on the CLD-1750/2950 but where is the button on the remote for DVL-909?

Not completely sure, but I remember correctly on the 919 to enable CX you just keep pressing the Audio button and it will cycle through from digital to analog then to analog CX.

Maybe the 909 is the same?

Okay I’ll try that I’ll give it try now on an analogue only STAR WARS PAL disc and see what luck I have.

No luck in CX switching ON no matter its not critical but it should be switching ON.

I tried holding down on the button for a few seconds nothing I tired holding down on the button while pressing another button at the same time nothing its just not switching to ON the CX.

Are you sure that the disc has CX applied? Just as there is an auto-trip code to set CX "on" (which will lock out the player control to turn it off, on most models), the code can also be set to set CX "off", & the player control will again be locked out. Not all non-CX discs have this code, but some do.

I'm not sure about your DVL-909.......but this is information from the Laserdisc Archive site for the DVL-700

With the addition of DVD capability, Pioneer, removed many standard LaserDisc features. Chief among these is the ability to manually activate CX Noise Reduction on old analog only titles that don't contain the Auto-CX code. As a result, on playback of discs made prior to 1983, you are at the mercy of the intrinsic noise level of the disc and are stuck with the 2:1 compression of the CX Noise Reduciton system.

So if you have a laserdisc that isn't encoded to turn the CX on automatically you can't manually.

Im used to have (but recently sold it) the Pioneer add on CX noise reduction box (about the size of a AC3 demodulator box) and you could run your audio through it and put CX on that way.

One thing worth mentioning is that, if you have a remote control unit for another model which does have a CX ON/OFF button or an A/D/CX button, you should try it. In some cases the functions are still there, there's just no way to access them using the standard front-panel & remote buttons.

Yeah I still have the remotes for 1950/2950 I’ll try that later on a\nd see if it enables the CX to switch ON.

No, no, it doesn’t work I tried both CLV-1750 and 2950 remotes and nothing they’re not even sending any remote commands I think the chip is different in those older model remotes. The Pioneer remote for DVL-909 will command other Pioneer DVD players as well as Pioneer DVD remotes sending commands to the laserdisc player but its still not switching ON the CX mode.

I give in.

That's right. The DVL 909 and 919 are beasically remote coded the same as the regular Pioneer DVD players. I used Pioneer DVD remotes on mine until I could get the oriinal remote cheap.

As far as CX goes, you won't be able to cycle through CX if the disc is coded as non-CX automatic, I suspect that disc of Star Wars is one of those.

That review of the DVL-700 that talked about there being no way to switch CX on was written by me and I had not figured out the trick yet of cycling through the audio to turn it on - you hit audio,then again and again till your back to stereo and the CX will be ON - do the cycle again and it will be Off. That's assuming it's an early disc without the Auto CX switching - many represses of early titles that added Minutes Seconds (and any disc with minutes seconds coding) has auto switching and sometimes it's switched OFF. A PAL disc might not even have CX encoding - even though Philips & Pioneer introduced PAL CX discs, PAL discs didn't need it - their FM audio carriers were so much lower in the spectrum that they had a much higher S/N and Dynamic Range than NTSC discs and CX wasn't the benefit for PAL LD's that it was for NTSC LD's.

But it worked on the CLD-1750 and 2950 with CX.

I must have pressed the button so many times and didn’t notice the slight sound change with possible CX turned to ON.
Maybe I should try again with an NTSC disc as CX is on most digital/analogue discs.
