RDL TX-70A 100/70/25 Volt to Unbalanced Line-Level Converter

If you need to feed audio from a 70V distributed loud speaker system into a line-level device at a remote location—or—if you need to add a few more loudspeakers than your existing 70V amplifier can drive, but have no convenient line-level audio to run into a local amplifier—no worries! Radio Design Labs has the module for you: the TX-70A.

Part of RDL's versatile TX-series products, it's a 70/25/100 volt input interface that's engineered to match a 100, 70 or 25 volt speaker line to any unbalanced line-level audio input. Simply install it just as you would a 70V speaker tap and adjust the trimmer for the optimal signal level. The TX-70A may be mounted directly to a backboard or chassis using a variety of mounting options available from Radio Design Labs.
