You can use the Line In jack, but you will probably need to use a mic preamp to raise the mic output sufficiently. You can try using an inexpensive mic from an amateur karaoke system or Guitar Hero etc. If that mic has no 1/8 inch mini phone plug, you can look for an adaptor, or have a tech type person set the mic cable up for you. If you want better quality, borrow or buy a professional vocal mic which uses an XLR cable and adapt the cable to plug into the 1/8 inch Line In jack on the keyboard. As I said, if the mic level is not loud enough, you can use a mic preamp, such as the ART Tube Mic Pre, which you can find used, or on a clear-out for maybe $25 to $35. Use a cable with a 1/4 inch connector on one end and a 1/8 inch connector on the other, to connect the mic pre output to the keyboard Line in. Plug the mic into the XLR input of the mic preamp. This will work 100%. Just adjust the mic preamp level controls carefully.

Yamaha has the user's guides available as PDFs for most of their instruments on their site: http://download.yamaha.com/top/?site=usa.yamaha.com&language=en . Enter PSR-6000 or select Pianos & Keyboards > Portable Keyboards > PSR-6000 and then press Select.

I hope this helps.

Is there a pattern to the wrong notes ( eg all up a semitone ? ) If so you could have altered the tuning. Try a master reset: Hold down top key whilst turning on. This will reset to factory setup. See attached for individual reset procedures:

It's Sitka Spruce.

That sounds like a problem with the contacts in the pedalboard or a short in the wiring harness. I'd suggest calling a tech in. You could cause a bigger problem if you aren't experienced.

Look for any drag of the key to the case or adjacent keys. Beyond that, the silicone rubber contact dome probably is damaged and needs replacing. Unit has to be opened and serviced. Parts are pprobably available from YamahaAmerica in CA.

Go to Yamaha America by phone in California: (888)-892-6242 ask for "parts" Have your model number and serial number ready and which keys are bad. I assume you are talking the keys are showing mechanical damage, as an electrical problem like contacts requires different parts to repair.

Possible causes: PSU fault. Power (audio) transistors overheating. Wrong speaker impedance. Dry joint. Needs technician to check.

The fact that ALL keys except G's and D flats are not working, points to a possible matrix or multiplexing problem. As shown in the simplified schematic, if any traces (PCB tracks) from the mutiplexer / controller IC are broken, eg if the board has a crack, this could disable all identical notes for all octaves. Otherwise the controller itself may have a fault. (Some non-related info): In reality, the synth's matrix is a bit more complicated than the basic sketch shown for explanation. Diodes are included per key to prevent 'phantom note playing' and to isolate keys. Velocity-sensing uses two set of contacts to sense timing from A to B contacts when key is struck.

Most Clavinovas can be removed from the stand by simply looking underneath and locating the fixing bolts. Yours will need lo be laid down onto the back edge, locate the bolts at the top of each leg, unlug any cabling for sustain, mains before laying down. See attached

Hi The normal reset is to hold down the highest note ( furtherst white key to the right ) at the same time as turning the instrument on. This will initiate a factory reset.

Firstly determine that the power supply you are using is providing the correct voltage, check with a multimeter. If it is correct then you need to open the piano. Look inside where the power plugs in check the little black socket and ensure that there are no breaks where this is soldered to the circuit board - very common problem. If so resolder or replace socket. Does turning the switch on make the red light come on - if not and socket is soldered correctly - suspect the switch - check continuity wilth multimeter, if switch is ok check voltage across pins 1 & 5 on CN2 on board this should read around 12v. if this doesnt show a voltage it is easier just to replace the whole DCIN board # WM227400

It looks like standard1/4" TRS connector. Tip-Ring-Sleeve. What are you trying to hook it up to? A standard guitar cord might work, but you'll get mono.

Certainly you could.

Hello, Magda - Only an authorized Yamaha digital piano (Clarinova) service technician can answer your question regarding a chance of repairing your piano.

Try local Yamaha dealer. They may not make house calls, few people these days do.What you might try if you are up to the challenge is flip the keyboard over- unplug it. remove the screws that hold the top and bottom shells together- do not let weight of unit rest on keys, especially when opening it up.Look for physical damage to the keyboard action in the vicinity of the nonfunctional section. Check for broken printed circuit board. If you see any cracks, see where it ends and drill a small hole at the end of the crack to halt propagation. clean the varnish off the circuit tracks and tin the broken tracks first on either side of the break then bridge them with solder. Use a modest sized soldering iron and small diameter (rosin core only) solder. If there are any broken wire connections, resolder them. This may require part of the action to be removed from case- take pictures first before proceeding- make sure they show exactly where the connectors are and what wires are present. etc. You want to be able to refer to the pictures in the event you forget details of disassembly.If nothing looks out of place, look for solder joints that do not appear to have flown out nicely- reflow them adding a little solder.
