DEMO Alctron U48 USB Audio interface

This is a Demo item, meaning it was used on a showroom floor so it is being sold at a reduced price. It may come without original packaging and may have minor blemishes. Some rack units may have deeper scratches on the chassis.   The U48 is a dual-channel sound card designed to convert analog signals into digital/digital signals into analog signals. The built-in amplifier circuit amplifies the input signal to make the signal output clearer and more transparent. The 24-bit 192 khz chip ensures the original sound quality. This sound card does not require any drive when it is running, and it is easy to use and plug and play. The various interfaces on the front and rear panels make the product suitable for more applications, and you can also ensure the sound quality is transparent through the adjustment of various switch knobs.Product parameters:* Sample rate: 24 bits / 192kHz* Frequency response: 20Hz 20 kHz +/- 0.1 dBMicrophone input* Frequency response: 20Hz 20 kHz +/- 0.1 dB* Distorti
