Parasound has introduced a 12-channel, 2-ohm stable power amplifier for commercial and residential audio systems installers with flexible power options for stereo audio in six rooms (zones), and up to 24 individual speakers. Uniquely, the 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.
