Much faster delivery than I expected. I got every penny of my moneys worth from this unit. I tested it using my Teac A3340 four channel reel to reel tape deck into the Biner mixer to my Pioneer AMFM/amplifier into my Sansui SP-X7900 speakers. All the controls worked perfectly. Good EQs and the graphic is a plus. All the patching is just first rate. The efx are a bit limited, but also offer many choices.I really think anyone who wants to have a home studio should grab one of these. Also, gigging musicians will find it does the job just supply the power! It does everything and pretty dang well.
