Russound DPA-1.2 - Manual (Page 7)

Speaker Outputs: The A and B speaker outputs are in parallel to the
amplifier output. When connected to the A or B output, either 6-
ohm or 8-Ohm speakers could be used. When using both A and B
speaker outputs, only speakers with impedance higher than 8
Ohms can be connected. For Bridge amplifier operation, connect
the + of the speaker to the R+ and - of the speaker to the L+ of the
amplifier.
