Hi,
Thanks for the reply.My receiver is onkyo r-100 made in japan 80's.I don't have the original remote , but I have seen it - it has bass+ - and treable + - direct buttons on the remote.I did't see other onkyo with bass and treable +- on the remote.Maybe is rare model.Also there is model r-100 Liverpool...The same.I have a pocket pc with win mobile and the sofware Noviiremote.I can input hex codes for each button. What are the Onkyo receiver Acr1+- and Acr2+- hex codes for?Is it audio controll or something?Thanks!

Most of this codes are working for me but I can't find bass+-:
