The TD-07's snare input [SNR cable] supports dual trigger (Head and Rim) response on the snare pad.
The TD-07 supports dual trigger results from the hihat, crash, and ride pads as well.
The tom inputs support head [single] triggering only. Rim trigger results on the tom pads is not possible.
To achieve dual trigger response from a pad, the sound module, pad, and cable must all support the dual trigger functionality.
