Creative Labs Sound Blaster SB1240 external sound card. This was a PC peripheral product that allowed users to enjoy high-quality sound and was all the rage. It connects to a PC via a USB cable. You can enjoy music with headphones or earphones directly, and the volume can be adjusted with the volume control. It also features RCA input/output, optical digital audio input/output, and a ground terminal. All terminals are gold-plated, paying close attention to sound quality. The exterior is in good condition. There are some scratches and minor blemishes, but they are not noticeable. I have connected it to a PC with Windows 11 and confirmed its operation. I confirmed that it can be used with earphones without drivers and that the RCA input/output works correctly. A USB cable (with two magnetic cores to reduce noise) is included. Will be shipped anonymously within 12 hours.
