Take note that the 33 and 45 adjustment screws are inverted from each other. Put the turntable down, test the speed, repeat if necessary. Insert it all the way in and carefully turn it until it sticks in the screw head.Īfter this, turn it just a little bit in a way or another depending if you want it to go faster or slower. They already have a slit for your screwdriver to go through. You will first have to go through a rubber cover for each hole. Now take a small straight screwdriver and insert it in the desired speed adjustment hole. Just lift the whole turntable by the front and you'll see two holes on the bottom with 33 and 45 markings on the left side. I would recommend putting a piece of tape on the tonearm so that you don't knock it over and break that fancy needle of yours. It's easy enough to do it yourself and you don't even need to put it upside down, open it or unplug it if you're careful. I spent an hour or two this weekend to look a it and finally adjusted it to a satisfactory speed. Just a quick update with my speed problem on my Denon DP300-F. Hope you can fix yours!ĮDIT: i searched iRPM in the apple store and it came up as a remote power manager for computers? I researched and found that its common for this Denon TT to have this speed issue, unfortunately. He dismantled it, rewired it, then tested it with a strobedisc and now its where it should be. He then found out that it was the electronics themselves that was making the TT spin too fast. I know this table has the adjustments underneath to tweak the speed, but the guy said that it wasn't changing after trying to adjust it. I am not knowledgeable with electronics or the innards of a TT so I brought it to my local stereo shop to have it looked at. I have this table and had the exact same issue regarding speed. I'll post an update if something comes up. I think the table ran a bit too fast since I bought it but I can't be sure now. I can see that the motor has a screw to change the speed so I'll try that if the belt looks fine. The table is a Denon DP300F and I have the service manual for it. The problem is either the belt (my table must be 4-5 years old) or the motor needs adjustment. I have good electronic knowledge and I think I'll be able to repair it myself. Thank you AJXD for the help on fixing my table. Oh hey thanks for the strobe disc tip! I forgot I could do that. You can post anymore usefull apps you might think people would like to discover. It might be the belt or the motor but I'll get to it soon. Unsurprisingly, the result was also 34.5 rpm so there is something wrong with my turntable. So basicly all you have to do is play the 3150 Hz track, start the app and check the results either in realtime or afterward when you're done. The app is called PlatterSpeed and is available here : I bought one from a dollar bin a couple of years ago so look around if you don't have one yet, they are fairly easy to find. Beforehand, you'll need a test record with a 3150 Hz track. Yesterday I decided to dig deeper into it as I am digitalising my music collection and after a few searches I found a very interesting app. I once tried an app called iRPM which gave me about 34.5 rpm but I did not have full confidence with it. Since my turntable did not come with a strobe light, verifying the speed is tricky. I tried to sync a song with a cd/mp3 of the same song and the difference was stunning. I suspected my turntable ran a slightly higher speed than it should. I figured it could help some of you as it helped me. Hello there, I want to share an app I just discovered yesterday.
