The Parasound ZM250 is a new class leading 2 channel 4 speaker & sub amplifier.

Depsite it's demure footprint, the ZM250 will deliver 50 watts of sonically superior audio quality per channel into 8 Ω and up to 90 watts per channel into a 4 (and yes it's high current design even enables powering loads down to 2 ohm as well). This power and flexibility is of course bridled with deceptively good fidelity, as can be seen in the ZM250's Class AB input stage plus premium Class D power stage - which is of course the key point of any Parasound product. As with any Parasound product, internal components are 'selected' and chosen for these key principles, they are just not assembled to meet the lowest common denominator of production criteria. Often 'Class D' amplifiers can be overly clinical and to an an extent unmusical - but the ZM250 excels with deep enveloping performance and very adept dynamics more akin to a class AB amplifier, and yet has the benefits (especially within custom installation) of low heat and low power consumption.

The ZM250 also has a very adaptable dedicated sub-woofer output, so that it can be the perfect amp for high quality installs where 2.1 set up's are required. Building upon connectivity for sub-woofers,the ZM250 also has an in built 80Hz low pass filter in bridged mode which means it is ideal for driving in-wall/in-ceiling woofers/passive sub(s). So in effect the ZM250 is a little bit like a 'swiss arny knife' for higher end custom intallation projects, so you can keep everything under one banner effectively - which means that the ZM250 can be called upon at all times to be flexible and yet bullet proof in a host of scenarios.

Another highly adaptable feature is the provision of a mono mode, that combines L and R for single speaker applications. This easily overlooked feature means that it can be used highly effectively in corridors, semi commercial installations where stereo imaging is not beneficial and finally a potential 'get out of jail card' for 'compromised' installations too. The ZM250 also features as a consequnce a full range mono RCA output too, so amps can be stacked together and looped together very simply, and with the best level of interconnectivity.
