I tried recording using the "aux" channel on the front panel plugged into an ipad, with the record selector on "aux"... all my cables are in properly. I did get some recording on the tape, but it's extremely low volume and poor quality, and the VU meters on the tape deck still didn't move during recording, and that's with the "line-in" adjustment knob on the cassette deck turned up to '10'. ... ???... the Sony deck is newly acquired, and perhaps the "record" feature is not working, but strange that I couldn't get anything out of my Kenwood cassette recorder either?

I guess I'll try to get the Sony deck serviced.

Anyone used the "record" output with the RR2150 sent to a cassette deck?

thanks
