I've got a Onkyo TX-NR3007 reciever, had this for a while, had no problems. Ive just bought a UP-DT1 add on Tuner to go with the reciever, hooked this up as per instructions but the amp is saying *not support* on the display and all im getting is clicks, nothing else. Is this add on faulty? or am I missing something? HELP!
