I plan on exchanging my 2000 (for another 2000) anyway due to a different problem, but I just noticed that the internal speakers produce considerable noise. It's difficult to quantify the noise without any measuring equipment, but noise is noise. How much noise is normal for the PSR 2000? Is there a known issue of too much noise on certain units?

I don't know about other PSR2000's out there, but the speakers on my unit are practically silent (very slight hiss can be heard and ONLY if you put your ear right up to a speaker), even with the master volume knob turned all the way UP. In fact, I think my PSR2000's internal amp is quieter than any other arranger KB I can remember.

MarcK,
It's the mic input that's noisy. There is no hiss in mine either, except when the mic settings boost the high range. Even with flat EQ settings, the mic input adds alot of noise to the output. Try the mute, and see the difference. I don't think that will be any different on another unit.

Thanks Scott, that's good to know! Now I have another reason to return the keyboard. The noise level on my 2000 isn't affected by the volume knob either; it's basically a constant hiss. Well, at least the defect is consistent .

Wow, this forum is lively -- Uncle Dave, I started writing that last reply before your reply, and yours was up when I finished mine! I'll take a look at how the mic setting affect the noise.

Hi, I returned my 2000 also (see my new post write letter....) I think if Yamaha is listening they must help us mine hissed like a snake!!

No hiss in mine, not with or without mic.

No hiss on mine. I'm very satisfied. Some of those CVP209 piano styles are awesome. Worth checking out.

Uncle Dave is right. There is nothing else for + or - $1000 out there that even comes close to doing what this keyboard does.

No speaker hiss on my PSR2000 either. In fact, it's my Korg pa80 that has the annoying speaker-hiss feature. And it is the mic input on that keyboard that causes it!

Check the lineouts, I rarely use internal speakers for serious work on the PSR - as long as the line outs are quiet, that's all thats important. There is usually a little hiss present on the internal amplifiers at any volume (the power amps create the hiss present at zero volume and the preamps and D-A convertors in the PSR give the noise when you crank the volume up). Also try headphones, as they are usually driven by an independent amplifier. Unless the noise is really distracting (like a radio tuned off station on Fm!) I dont think you have a problem. I know the power amplifier modules in these keyboards are pretty robust, I had a strange experience once with my 740 where somehow feedback induced a periodic thumping noise in the internal speakers.. It wouldnt go away even when the keyboard was turned off and back on. However I left it overnight disconnected and it had recovered by the morning!

Hi Marck, ( and other friends)
I'd like to tell you a story about sound in the internal speakers on my 2000!
I bought me a clamp to fasten onto my KB stand to mount a short 30" mic boom!
Didn't like it right off, the mic shook around to much! But that wasn't the worst part, it made a rumbling sound it the internal speakers! I went back to a seperate
stand.
But "Marck" I just now tried my KB, at max vol & my ear right the speakers I can verly hear any hiss at all! The Mic is on & set at 100 which is factory default setting! No hissing!
Hope you get yours to working right!
All the best,
Nobby

Nobby,
If the clamp is secure, and the keyboard support arms have a rubber pad, and there is not too much bounce in the stand - you should be able to eliminate the rumble. The most important element is the keyboard bounce. There are NO single "X" type stands that are secure enough for me. Try a double braced one - it makes a big difference !

I've been reading much of the emails, but this is my first time posting a reply. Let me first say "Hi" to everyone and thanks for all the great information, including the help you've given me in selecting the PSR2000. It's a perfect addition to my setup.

Regarding the "hissing sound". I've been spending a lot of time trying to minimize it. I've spoken with Yamaha support and worked with experienced people from the store I bought it from. Some of the comments in the emails were right on. Let me give you my opinion based on what I have learned.

The hiss is produced only when the mic input is used. The hissing sound is most noticeable immediately after saying something into the MIC, especially when the volume is turned up. This happens when
using the main speakers, the headphones, or the line outs. When the MIC is off, there is no hiss at all while playing the keyboard.

I've tried changing between low impedance and high impedance MICs (one of the MICs I use is an SM58). Not much affect. I also thought it could have just been a problem with my specific keyboard, but we were able to duplicate the same exact thing with the model in the store.

I believe this hiss is related to the noise-gate. When the noise-gate is on, it suppresses any noise from the MIC input by simply switching it off. It automatically switches it on when it senses a threshold has been hit at the input of the MIC. Note that this threshold is programmable (MIC SETTING page). For those who mentioned that they have a constant hiss, it could be because they have the noise gate turned off.

I believe what's happening is that when the noise-gate senses you speaking into the MIC, the voice signal is let through along with any accompanying noise from that input or the internal A/D circuitry. When you stop speaking into the MIC, the noise-gate eventually switches off, and the sound is perfectly clean again. However, I believe there is a lag in the detection of the signal going away, and this is causing the noise (or hiss) to stay on for a short time after you stop speaking. (This is my guess...I really don't have enough knowledge of the circuitry).

I have not found the programmable threshold to help much with the hiss. The only true way I have found to minimize the hiss, is exactly what was suggested in previous replies...lower the high-end filter. Through experimenting, I have found that the best setting is 8KHz with -5dB attentuation for the EQ HIGH (I think the factory settings were at 16KHz). You can do this on the MIC SETTING page. Note that you can completely eliminate the hiss by fully attenuating the highs, but your voice won't sound too good. I've found this setting to be the best compromise. You'll have to find your personal favorite.

If anyone's figured out a better setting, or any other techniques to minimize the hiss, I would love to hear it. Yamaha told me they were not receiving any complaints about this hiss, so they were not able to offer much help to me. They did not validate or deny my theory of the "hiss lag".

It's interesting to note that the overall noise suppression for this instrument is really pretty good. It's just that when the noise-gate is on, it's perfect, so it makes the noise so noticeable when it switches off. It would be ideal to have that all the time....but too much to ask for in this price range.

Of course, when playing full songs with accompaniment, it's hard to notice
the hiss. But, when playing piano songs like "Desperado" and using the MIC
for vocals, it's very noticeable.

I hope this helps.

-Thanks, Kevin

I didn't try this yet, but it MIGHT work. Most of the hiss is exagerated with high EQ, so try using an outboard eq, and keeping the internal settings at flat response. Since I got the Voice Prism, I doubt that I'll ever use the mic input again, except for my guitar, or in a nursing home type gig. It's a great convenience, but not such a great mic preamp. When time and tiny is important - the internal mic is going to have to do, but when the sound is a bigger issue, I will not use the "hiss box" anymore.
BTW - I keep the noise gate, AND the compressor OFF. They both color the tone too much, and I think the noise gate actually attracts attention to the hiss. It's another nice add-on, but not up to the quality of a studio gate. I'd rather see them leave out the sub-standard items and beef-up some other areas, like the flash ram section, or the flimsy keys.
Again, I have to repeat - It's still a greatr value for the money !

I have experimented with just about every possible combination of mic e.q. and overall e.q. I don't have any hiss at all unless if the noise gate and compressor/limiter are off. I've used several different mics including Shure SM87 and Behringers.
I suspect either the noise gate or compressor is the cuprit.

If you don't hear it, that has to be because the gate is set to open when the voice is loud enough. Trust me, the hiss is there. It's SO there.
