Yamaha Audio question ?

[Audio Al]

I own a Yamaha CX- 2 pre amp and a MX 2 power amp

I also managed to purchase a new remote control unit RCX

On the remote it also has :-

Tuner button
CD button
Tape 1
Tape 2

Does anyone know what model numbers are compatible with the above pre and power amps and will work with the remote ?

thanks :)
