With the USBP-13 you can entered the new age of musical enjoyment, with the ability to reproduce recorded music more accurate than ever before.

The recent developments in high resolution computer readable formats, allow you to listen to the finest recordings that are easily distributed as downloads.

Precision separated stabilized ultra low noise supplies power the separated stages.

The USB receiver is clocked by a high stability and low phase noise OCXO oscillators.

The Texas Instruments PCM5122 DAC and the OCXO clock are placed in the DAC stage.

The USBP-13 is connected to the PC with a USB cable.

All functions and settings are made from the PC.

You can remotely control the computer application with any mobile phone.

*** The Texas Instruments PCM5122 is a 32-bit DAC, which corresponds to high-performance, high sound quality digital audio systems.

Internal circuits includes newly developed 32-bit digital filters for better sound quality and a DSP.

It has increasing performance for systems with excessive clock jitter and accepts up to 384kHz PCM data.

Specifications

SNR: 112db

THD+noise@-1dbFS: -93db

Audio data formats: 16-bit to 32-bit

Sample rates: up to 384KHz

** OCXO or oven controlled crystal oscillator.

A crystal oscillator uses the mechanical resonance of a vibrating crystal to create an electrical signal with a precise frequency.

The OCXO circuit is placed in an oven chamber with stable high temperature for stability.

The clock is stable at 0.1ppm.

Specifications

Stability: 0.1ppm

Phase noise: 90dbc/Hz@ 10Hz, -120dbc/Hz@10KHz
