jaykay Posted December 30, 2019 Share Posted December 30, 2019 Hello, I recently purchased the Casio CPD-S350 and I've noticed that the case/speakers reverberate/crackle at higher volumes, is this typical? It tends to be the right speaker that's worse, if I put some weight down on that side over the speaker it gets better. It's pretty much ok up to max volume on the stage piano setting but if I layer a pad or use some of the other tones like the organs I'm not able to turn the volume much past 12 o clock before the reverberating/crackling starts. Maybe I'm expecting too much from the internal speakers but reviews suggested they were pretty good so I'm wondering if there's an issue with my keyboard or if this behaviour should be expected. Many thanks. Quote Link to comment Share on other sites More sharing options...
Joe Muscara Posted December 30, 2019 Share Posted December 30, 2019 I have not turned one up that much but I suspect that's not normal. If you purchased it at a store, I'd suggest going back to the store and seeing if the floor model does the same thing or not. If it doesn't, go back out to your car and bring in yours and tell them you want to exchange it. 1 Quote Link to comment Share on other sites More sharing options...
jaykay Posted December 30, 2019 Author Share Posted December 30, 2019 Thanks for the reply. Unfortunately I bought it online as I couldn't find any local stores that sold it. If anyone has the same model and could test what theirs is like for me that would be great, I would rather not have to go through the process of returning it but if it is faulty then that's a different matter, thanks again.

jaykay Posted January 6, 2020 Author Share Posted January 6, 2020 Just for info in case it's useful to anyone....I ended up exchanging the CDP-S350 and the new one is fine so there was an issue with the speaker on the first one! Thanks 1 1 Quote Link to comment Share on other sites More sharing options...
Bryzzee Posted February 1, 2020 Share Posted February 1, 2020 I have a useful suggestion and idea that can be done for amplification purposes. This method can be done very cheaply and provide you with extreme volume levels. The main question is how loud do you want to go ? Do you want to blow the windows out of your house or apartment, or perhaps the door off it's hinges ? Instead of thinking of buying those very expensive ilouds or two thousand dollar self powered monitor speakers or keyboard amps, try using this setup instead. I have been using this setup configuration for years without any problems of any kind and I can easily get the loud volume amplification of booming bass and high fidelity that I want or need. What I did is simply purchased at a pawn shop ( years ago for 50 dollars) a old Sony home theater 5.1 amp and pair of speakers (mine are huge 3 way 15") to match for keyboard amplification purposes. Due to the home theater amp having RCA inputs, all you need to do is find yourself a 1/4 inch headphone jack with RCA ends or a stereo mini plug with 1\4 inch headphone adaptor plug for the RCA wire giving stereo output from your keyboard headphone jack to the RCA input line of the CD mode of the home theater amp ( giving 2 ch. stereo ) or any provided mode the amp may have for L & R stereo audio. The RCA wires can come in all types of wired configurations. Some keyboards are already equipped with RCA outputs. If your keyboard doesn't have RCA outputs you can alternatively use the stereo headphone jack output of your keyboard into the back RCA inputs of the home theater amp the sound then goes out to the hooked up speakers of the amp. It really depends on what type of amplifier you prefer to use along with what inputs and outputs and the wire\cable connectors it may provide to use from home theater amps to DJ amps in connection to your keyboard. Most keyboards now have both separate 1\4 inch L&R line outputs and 1\4 inch L&R line inputs to an external amp or even XLR connections. If using a home theater amp as I have, you will need RCA wire with a 1\4 inch headphone plug adaptor connected to one of the RCA wire ends which is connected from your keyboard headphone output jack and the other end of the RCA jacks into the back of the home theater amp. You don't loose the ability to use your headphones as most likely the home theater amp will have its own headphone capability that you can easily switch to use for private listening. Even a mixer can be used and utilized like a DJ or PA sound system setup with your keyboard. This idea or concept for amplification is not new, but it most certainly works very well from simple to elaborate, and can be easily done for much less cost then the alternative of buying very expensive amp and speaker gear just to amplify the sound of your keyboard. There are other less expensive ways or options to consider as well such as Logitech Gaming surround sound amplification with subwoofer, and wireless Bluetooth that can be utilized for amplifying the sound of your keyboard for full rich booming bass and high fidelity sound which makes a tremendous difference instead of using the 8watts per side onboard speakers.
