Compare the four-channel transmitter arrangements

DT-4A lists exact receiver arrangements. DT3+1 describes a separate channel-1 system code without naming receiver models. Keep these source scopes separate; the similar supplier numbers do not establish equivalence.

Separate references with their own source scope. This comparison establishes no replacement or interchangeability.
