A Phono input is also provided for connecting a turntable.
Making Connections Outputs Use the REC output to connect a stand-alone CD recorder, DAT recorder, or tape deck. Use the BOOTH output to connect directly to powered monitors or your monitor amp.

Master These outputs are for connecting your main power amp, EQ, crossover, etc. Both RCA and 1/4-inch jacks are provided.
