Parasound ZoneMaster Z-12

Parasound ZoneMaster ZM 12 drives two channels at 120 watts each, 8 ohms, with the remaining 10 channels at 60 watts each. With 4-ohm speakers typical of architectural audio, the ratings are 150 and 100 watts respectively. There are also A and B speaker outputs for each channel. With this upgraded performance and features, the ZM 12 represents a significant advance over its 12 x 50W predecessor, the ZM 1250.
