Provides signal matching between unbalanced and balanced audio equipment  
— The BUC 102 enables correct interfacing of consumer and professional equipment  
with proper gain offsets.  
NOTE: 0 dBu = 0.775 Vrms, 0 dBV = 1 Vrms, 0 dBV ≈ 2 dBu.  
Audio outPut  
Audio line driver — Active, op amp-based circuitry provides wide frequency  
response, low noise, immunity to interference - EMI, and the ability to drive signals over  
long cables.
