Impedance Matcher for Balanced/Unbalanced Gear

Painlessly pair your consumer and pro audio gear with the Aphex 124B impedance matcher. This little box lets you marry unbalanced (-10dBv) and balanced (+4/+8dBm) equipment on the way in and out, allowing you to interface with home CD players, cassette 4-tracks, hi-fi speakers, and vintage rack gear without added noise or overloading. The Aphex 124B's two-way buffer not only matches impedance and operating levels, but also serves as a line driver for running long cable outputs without loss of signal and tone. Finally, the 124B acts as a signal splitter for reliably converting a single mono signal into two balanced outs for creative routing options. Sweetwater engineers recommend using the 124B to run a guitar, bass, or keyboard into two different pieces of rack gear to explore new tonal options!

Aphex 124B 2-channel Impedance Matcher Features:
  • Reliably matches unbalanced and balanced signals
  • Incorporate consumer-grade speakers, CD/tape players, and EQs into your pro setup
  • Use unbalanced vintage audio gear without signal loss
  • Bidirectional buffer with balanced XLR ins and outs
  • Line driver allows for long cable runs without signal/tone loss
  • Y-splitter converts a mono signal into 2 balanced signals
  • Rackmount kit sold separately
Explore creative signal processing with the Aphex 124B 2-channel Impedance Matcher!
