Home theater questions? Ask a technician for answers ASAP
I'm sorry you're having problems and I will do my best to help. In order to connect the Bose 901 EQ you will need to connect it between the Denon and the Niles so that all signal going to the Niles is first fed through the Bose EQ. Right now how do you have the Denon connected to the Niles?
Okay now I'm confused. Where did the Numarl EQ come from? I thought you had the Bose EQ? Also, I asked a specific question needed to help you- Right now how do you have the Denon connected to the Niles?
Okay, this isn't going to be an easy setup, first you will only be able to use one EQ, and that would be the Bose. Second, the Denon has no line level outputs, so in order to connect it to the Niles amplifier, you will need a speaker to line level converter connected to the Denon's Left and Right main speaker outputs (because the Denon lacks the Tape Monitor Loop the previous Onkyo likely had).
