If your source unit has low output voltage or your amplifiers are located far back in a Van or SUV, the BLD is a perfect for your system. Featuring 'Balanced Differential' or 'Single Ended' mode, its high voltage output combined with a low output impedance will drive large arrays of amplifiers without breaking a sweat. In 'Balanced Differential' mode, it's twisted pair design also helps eliminate radiated noise through electrical cancellation.
