In my gr 33 the volume is very low. mistakenly i did a factory reset after that the volume is becomes very very low. Any solution for this problem?

If certain notes on your Technics SX-PR150 digital piano are playing at a lower volume than others, it's possible that there could be a few underlying reasons for this issue. Here are some steps you can take to troubleshoot and potentially resolve the problem:

1. Dust and Debris:
   • Check if there is any dust, debris, or foreign objects present around the keys and internal components. Dust or debris could affect the key's action and cause uneven volume levels.
2. Contact Cleaning:
   • If you're comfortable doing so, you can carefully open the piano and clean the contacts underneath the affected keys. Contacts that have accumulated dirt or oxidation might lead to volume inconsistencies. Use a clean, dry cloth or contact cleaner specifically designed for electronics.
3. Key Mechanism:
   • Inspect the key mechanism for any signs of physical damage, misalignment, or wear. Damaged or misaligned keys could lead to uneven volume levels.
4. Sensors and Sensors Board:
   • Digital pianos like the Technics SX-PR150 use sensors to detect key presses and control volume. If a sensor is malfunctioning or damaged, it could result in volume inconsistencies. Check the sensors and their connections for any issues.
5. Audio Output and Amplification:
   • Check if the issue is specific to the internal speakers or if it also occurs when using headphones or external amplification. If the issue is present across all audio outputs, it might be related to the piano's internal components.
6. Factory Reset:
   • Perform a factory reset on the piano to restore its settings to default. This can help rule out any software-related issues that might be affecting the volume levels.
7. Professional Inspection:
   • If the above steps do not resolve the issue, it's recommended to seek the assistance of a professional technician who is experienced in repairing digital pianos. They can diagnose the problem accurately and perform any necessary repairs.

Please exercise caution while performing any internal inspections or repairs on your digital piano, especially if you're not experienced in working with electronic equipment. If you're unsure or uncomfortable with the process, it's best to seek professional help to avoid causing further damage.

Work ALL switches and controls, if a switch or control sits doing nothing for long periods of time they will become resistive if not open. Just work every one and see if that doesn't fix it.

It's doubtful it's a problem that a reset would help. It sounds more like a problem with the contact on that specific key. I suggest taking it to the repair shop.

I don't think it's possible to reset a Faderport in the traditional sense since the firmware is not an EPROM (Electrostatic-Programmable-Read-Only-Memory).

I think it's more likely that the driver on your PC or Mac has become corrupted and needs to be uninstalled and reinstalled.

To do this, we'll need to know more about your platform, especially the DAW. Are you using Studio One v2 or v3?

With IDES4, I can load factory defaults to my WK8000.
WK500 uses DATA MANAGER 5.0. If I am not mistaken, you can only save/restore/delete "user data" from and to the instrument.
FACTORY Settings are always unchanged in the instrument and it reset itself every time you power cycle.

Hi,

try lowering the volume to the minimum instead of increasing it. And to mask the volume drop out, please use only half or at most 70% of your speakers at once and drop off the volume for those while you turn up the volume for to other 30% which will be the opposite volume of your main speakers. The second set covers the volume drop that you might need to do during a show. In the mean time, you can setup a repair appointment to get the volume issue fixed.

Thank you

Try connecting them to another amplifier...you can use the speaker output of a guitar amp as a quick test. If the amp (and mixer) check OK, it sounds like you are about to become good friends with your local speaker reconing shop.

Remember...Distorted Audio Can Kill Speakers even at low volumes. It happens because sine waves become square waves. Google it for additional information.

There is probably a power supply failure or with the power on reset circuit. Likely low voltage to the logic electronics. This is NOT DIY unless you are familiar with electronics.

One of the internal data for one touch has become corrupted. The best thing is to do a factory reset. Read your manual and follw the directions for a factory reset.
