The "Audio Bit Buddy" portable digital/analog audio monitor is the convenient way to monitor both digital (AES/EBU, S/PDIF) and analog audio signals. The Audio Bit Buddy is ideal for any studio or technical environment where digital or analog audio signals are used. The low cost, battery operated, and high function design places the Audio Bit Buddy in high demand for servicing experts in professional and consumer facilities including broadcast installations, production studios, signal distribution facilities and other locations where digital and analog audio signals are used. Digital and analog program audio can be monitored by the headphone output while the L/R levels are displayed on LED bar graph meters. Critical signal parameters such as sampling frequency, emphasis, professional consumer format and data errors are displayed when monitoring AES/EBU or S/PDIF signals. Digital input monitors sampling frequencies from 30kHz to 50kHz automatically. For unbalanced 75 Ohm digital audio signals, use an in-line impedance matching transformer such as the Sescom SES-AES-EBU-2.
