SoundPals DTG-1 Digital Test Generator

SoundPals™ DTG-1
Digital Test Generator

The DTG-1 is an economical source of a variety of audio test signals that are generated entirely in the digital domain and output in the AES/EBU format. Use it in the studio as a reference tone generator or on the bench as a troubleshooting tool. Rugged, compact, and capable of running off battery power, the DTG-1 is also ideal for portable applications. The DTG-1 has internal oscillators for both 44.1 and 48kHz sample rates, or it may be locked to an external reference. The DTG-1 has all the adjustments needed to make isolation of digital transmission problems simple and easy to find. Like all of the modules in the SoundPals™ line, the DTG-1 is housed in a compact, rugged aluminum enclosure.

Features include:

Switch selectable output signals include discrete sine waves, sweep, white noise, pink noise and more

Level of test signals is adjustable from 0 to -60dBFS

Front panel dipswitch for setting channel status bits and operating mode
