I lucked out when shopping for external speakers for my PX-560 and found a set of JBL LSR305 speakers on sale. These are hard to find as they have been superseded by a newer (and not necessarily better) model. I have them connected with a balanced XLR cable to phono cable from the speaker to the 560 line out. Problem is, despite being "powered" speakers, they don't seem any louder than those built in to the keyboard. I find myself bending over the keyboard to see if they are actually making a sound. I thought that these speakers might blow me off my piano stool with the volume set just below max, but not even close. Speaker trim is zeroed out and input sensitivity switch is at -10db. Am I doing something wrong? Update: April 24/2018 - Pretty disappointed with JBL. Sent them and Casio the same question as above and have received a reply only from Casio. Have scoured the Internet myself and may have found a solution. Silly me bought an XLR to 1/4" cable believing that it was the more professional way to go. Maybe so, but I cobbled together a 1/4" to 1/4" plug I had from spare parts lying around and went from 1/4" to 1/4" instead of XLR to 1/4". Guess what - an obvious increase in volume, just by using a different connector. Why on earth does that not appear in the JBL literature!? So, I'm off to find a pair of good 1/4" cables.

Thanks, Brad. That little devil...I must make a point of checking that after my grandson is finished with his "creations". That also solves the mystery of why my grand piano sounded so electric.

On the recommendation of another user, I went out and bought an M-Audio SP-2 sustain pedal to replace the flimsy damper pedal supplied by Casio (which works). The SP-2 is a major upgrade in quality, heft and touch. HOWEVER, it appears to induce a mild tremolo with the sustain. It's pretty, but not wanted. Any suggestions besides take it back? Update: I just plugged the original damper pedal back in, and guess what? The same tremolo is still there. I did a factory reset (I allow my 6-year-old grandson "free time" after his lesson) in case something had been changed. Tremolo is still there. I've only had the 560 a couple of weeks and am still becoming familiar with it. Didn't notice the tremolo before (old age I guess). Is this a common trait of this machine? BTW - have 1.14 firmware.
