Allen & Heath Xone:43C With Original Box [Requires Maintenance, Sold As-Is]

This is the Allen & Heath 4-channel digital DJ mixer Xone:43C. It features a highly-rated built-in sound card and supports Serato DJ DVS. This legendary mixer is now discontinued and difficult to find on the market. However, it is being listed for repair and maintenance due to the following issues:

This is a high-quality, multi-functional mixer, so please consider purchasing only if you understand its current condition.

■ Background and Exterior
I purchased this unit used several years ago and used it as a preamplifier for listening for about six months. After acquiring different equipment, I stored it in its original box indoors as a backup unit.
The top panel is clean with no scratches, but there are light scuffs on both sides. Please refer to photos 5-7.

■ Issues and Operational Status
Upon powering it up after a long time, I discovered the following issues:
When the power is turned on, a small humming noise is constantly present. Occasional small crackling sounds are also heard.
*Based on my experience, I suspect this is an issue with an internal IC that can be fixed with replacement, but I have not had it professionally diagnosed, so the exact cause is unknown.

Sound is produced through both Phono/Line inputs.
There is no crackling or noise from the EQ or faders.
The filter also functions without any problems.
*The interface function (USB connection) and Serato DVS integration have not been tested as I do not currently have the necessary environment.

■ Accessories
Main unit, power cable
Original box (with some scratches and tears)
Spare knob caps
