The PV 1600 Bi-Pack is an integrated, all-in-one power solution for bi-amping non-powered speakers such as the Peavey SP(TM) 2, SP 4 or Impulse(R) 1015. The PV 1600 Bi-Pack delivers 930 watts to woofers (lows) and 350 watts to compression drivers (highs) through a specialized crossover with built-in EQ and phase adjustment. In addition to a 50 Hz bass boost with roll off, a gentle slope throughout the rest of the low frequency range is utilized up to the crossover frequency.
I use 2 of these to power 2 SP4 enclosures and since they are taylored to these speakers they are almost perfect. And Abes of Maine had a great price and got them to me worry free no problems, Thanks
