Parasound has introduced a 12-channel, 2-ohm stable power amplifier for both residential and commercial applications, with availability for stereo audio in six rooms and up to 24 individual speakers. The Parasound ZoneMaster ZM 12 drives two channels at 120 watts each into 8 ohms, with the remaining 10 channels at 60 watts each. With 4-ohm speakers, the ratings are 150 and 100 watts respectively. There are also A and B speaker outputs for each channel. Parasound says the upgrade represents a significant advance over the previous 12 x 50W ZM 1250.
“Providing higher power for two of the 12 channels seems obvious now that we’ve done it,” said Parasound president, Richard Schram. “Nearly all installations have a zone which can sing nicely with higher power – either a large rec room, outdoor speakers, or a room for serious stereo listening.”
The ZM 12 has a higher-power Zone 1 (channels 1 & 2) with its upgrade to 120 watts per channel into 8 ohms and 150 watts per channel into 4 or 2 ohms. Each zone incudes a Parasound-designed premium Class AB stereo input stage driving six new Danish ICEpower stereo amplifier modules that are 2-ohm stable. Each channel has an individual line-level input jack, level control, and two detachable Phoenix-connector speaker outputs. Each zone can connect to one of two line-level buses or to a speaker-level input bus. Buffered loop outputs facilitate daisy-chaining amplifiers.
The ZM 12 has a black finish and is designed for rack mounting and die-cast mounting brackets are included. The unit is currently available with a suggested US retail price of $2,495.
