The AB-8 from SM Pro Audio is an 8 channel input device that converts line-level audio signals into the ADAT lightpipe format. Many of today's computer audio interfaces and digital mixing consoles feature ADAT lightpipe inputs, and the AB-8 is great way to affordably put them to use.
The AB-8 stands out because instead of being packed with microphone preamps and other circuitry that raise the noise-floor of the unit, it offers 8 transformer isolated line inputs with passive level attenuators on each channel. The isolated inputs protect your audio from the hum and noise that can occur when grounding and power issues arise.
Featuring wordclock input and output, the AB-8 will sync with an external clock or act as the master. It will operate at either 44.1 or 48kHz, and features a 24-bit 96kHz Delta Sigma converter. With a rugged, all metal construction and a compact single rack space design, the AB-8 is a great option for anyone who needs a low-noise ADAT converter at a budget-friendly price.
