These handy boxes can be used to match consumer grade audio devices (-10dB) to pro equipment (+4dB). These units convert the level and provide the conversion from balanced to unbalanced operation and vice-versa.
Each unit features:
- XLR, TRS mini and RCA phono jacks
- Level controls
- Active circuitry, power by Whirlwind PS24 supply (included)
