Need replacement mics for PT300 packs. - AKG (WMS40DIV444US54) Microphone

it has mic problem...replace its mic..

fixya site doesn't sell anything
most fountain pumps can be bought from nursery supplies , quality hard ware retailers and some irrigation pump and parts retailers
take your pump along as a sample to get the correct voltage and pump capacity
most are a simple impeller running on a plastic shaft and they fail because moss, weed , hair etc wrap around the shaft and jam the impeller movement

You probably can't disassemble the factory connector. What you CAN do is find a replacement connector (internet) that's designed for retrofit to your cable and install it on the good section of the cable.

It looks like a mini XLR connection at the belt pack end, so that's easy. The cable goes to a connector block which looks like it is held together with two screws. Again, that should be fairly straightforward.

The other side of the block is the cable that goes up to the head set and boom mic. This looks a little trickier for a novice just because the mic capsule is small; the cable runs through a narrow diameter tube, and the cable routing involves heatshrink.

At a guess I'd say that the foam windshield will come off. There'll be a grub screw holding the collar in place.

Personally, I'd use a meter on continuity setting, upen up the XLR and connectors block, and test the two signal lines (pins 2 and 3 in the XLR) for a break. Fingers crossed it is in that section. Then replace that cable.

If it is in the boom arm section, and you feel confident dealing with threading the cable and using heat shrink then have a go. If not, take it to a Tech to avoid the risk of wrecking a great mic.

Try switching mic's with known good system. The small diameter cable going to headset and lav mic's are easily damaged. If the mic feeding the bodypack is good, fresh battery, mute disengaged and channels set properly then it's Shure factory service time.

I take it you installed the Driver Pack.....try also installing the Software Installation Pack.

Here also is the link for the Installation Guide and Manual, always worth reading....

If the unit uses a wall transformer, make sure you have the right unit.

The Yamaha correct ones are branded Yamaha. Use of the wrong one can damage keybooard or be inoperative.

The PT300 did not come up as a valid keyboard. Suspect the number is either YPT-300 or a P-300..

It sounds to me like you have a short in the cable. Power up unit like normal and move the wires at each end of the cable, mic end and connector end, being careful not to move the mic. If you hear popping it's a bad cable. If not, now gently shake the mic, does it pop, then it's your mic's capsule and needs replacement.
