CVP 209 Audio In

[waine_manor]

Hello. I'd like to be able to feed amplified audio (maximum of about 40 watts RMS) into the audio inputs on my CVP209 so that I can play CDs etc through the piano's speakers ... but I don't know how much I can punch in without wrecking any electronics that might exist between the inputs and the speakers, or the speakers themselves. The local Yamaha dealer says he's not sure ... does anyone know? thanks

I run an unamplified output from the souncard on my PC to the audio input of my CVP 209. This works very well for listening to MP3 files watching DVD on the PC monitor etc.

I am almost sure that running an amplified output to the CVP input will blow something and I would certainly not recommend trying it.

Is there no unamplified output on your CD player that you can use? You may want to consider buying something with such an output or even consider hooking up your PC as the sound quality throught the CVP speaker system is very good.

HI

DO NOT EVEN THINK ABOUT IT

YOU WILL DESTROY IT.

It would be like pluging a flash light into the mains.

You can of course, feed to output of you cd player's TAPE out or LINE out into the CVP. BUT not anything that would have gone to your speakers.

I had to read your post a good number of times just to make sure you REALY wanted to do that.

A small, inexpensive,($30-$50), reasonable quality personal CD player will do the job. Just connect the player earphone output to the audio in of the Clav.

No.. you can't.. it will kill the system, just like what midimagic said...

Niangao,
In case you misunderstood my post, the type of CD player I was referring to is the small battery operated player which can also be used with a wall wart power transformer. The type that is just a little larger than the CD itself.
The headphone output of these players is in the 5mW range...not even close to the 40 watts that the original poster and Midimagic were discussing. It's true that any amplified output measured in watts will surely damage the Clav.
However, the 5mW output level of a portable player is only sufficient to drive a set of earphones and can safely be connected to the input jacks of the Clav. It would be wise to experiment starting with a low volume setting on the player to avoid distortion.
I have been using one for years with no problems.

I have connected a small CD Portable player using the LINE Outs and it works like it should. I've also connected a karaoke CD Player again using the LINE output with good results. My karaoke player also has SPEAKER outputs at 35 RMS and I would NEVER connect it to the LINE ins of the CVP or any other audio device.

Phil might be correct about the headphone outputs from his small portable CD player, he usually is, but Midi Magic's warning should be heeded before you destroy your CVP.

If your player has a Line Out jack then by all means use it. Some players may have only an Ear Out jack and that will work just as well. My Archos Digital recorder has only an Ear out and works fine playing it through the Clav.
The output voltages will be in the same ballpark. The difference is that Line out is at a fixed level but the Ear Out level can be controlled by the player volume control. In some cases this may be desirable in that you can use a lower volume setting on the Clav. On the more expensive units the maximum Ear Out level may be slightly higher to compensate for high or low impedance headphones.
The main point to drive home is that you can use a player with the Clav but NOT from any amplified speaker level outputs.

Thanks everyone. Will clarify a bit - my old CVP109 had a line in that I used with PCs and CD players - I'd punch in a line level signal which was then amplified by the piano and played through its speakers. The problem now is the CVP209 doesn't seem to have a line level audio in - the audio in seems to pass the signal straight to the speakers (and this is fine - its just the speakers I want to use). But I'm not sure that there's no other bits in the signal path that might be damaged with a much larger signal - hence my first post. Will probably need to track down a circuit diagram or work out how to take the piano apart and track the wires. Until then I won't put any big signals in. Thanks again.

Hi

May I suggest you read page 153 of the owner's manual.
It shows that yoy have a "Aux In" and there is a diagram of a Tone generator with it's LINE OUT.

Also read the Note which tells you that the Master Volume affects the input signal from the Aux In.

So it CAN NOT go straight to the speakers.

This is the same as your 109 but they have called it Aux instead of Line.

noted, thanks. I think what I'll do is tap into the speaker cables diretly using a smart switch that prevents both the piano and the ext amp trying to pump a signal at the same time (like the headphone auto disconnect switch) - wrecked a Hammond organ once by not doing that.

I MUST ASK WHY

:confused: :confused: :confused: :confused: :confused:


Glad you have £5,000 to buy a new one.

Tapping into the speaker cables is not a good idea either. The 3 sets of speakers are connected through a series of crossover networks which are also solid state devices and could/would be seriously damaged. Connecting to the speakers themselves would mean disconnecting them from these networks and probably an impedance mismatch with whatever you are trying to attach.
It's kind of hard to figure out what it is you are trying to do here, maybe some more detail would be helpful.

Sounds like he's trying to wreck his 209 like the Hammond.

"wrecked a Hammond organ once by not doing that."

[waine_manor]

thanks - consensus seems to be to leave the piano alone ... i think i'll do that and just install a separate amp/speakers for CDs. Too busy trying to get my new plasma wide screen to display the LCD messages from the microwave oven anyway ...
