On most Rotel amplifiers this is not possible – all input linking should link to the A channel inputs – for example, if the system requires one channel to be separate while the other pairs are linked, the D channel should be set up as the independent channel, while A, B and C are linked.

The exception to this rule is the RKB-850/8100/D850/D8100 V02 amplifiers. On these models input linking has been improved so that if a channel is set to "Link", it will link to the previous channel input. So for example setting channel C to link mode will now link to channel B and so on. With this design you could now link channels A+B as one common source, and link channels C+D as another, for example.
