Product description
New Version v.2
This is the new v.2 version of the Model 2250 with several new features for enhanced performance and convenience. First is a new A/B speaker button lockout switch on the rear panel. When this switch is set to Lockout, the front panel A and B buttons are disabled and speakers A and B will always be on. This can be particularly useful for a professional audio installer who never intends for the client to use the front panel buttons.
The new ultra-sensitive two-position audio trigger allowed Parasound to eliminate the audio trigger sensitivity knob. A 'Quieter' setting will automatically turn on the amp at a very low volume. If this isn't sensitive enough for your system needs, you can also use the 'Louder' setting.
The 12 volt trigger jacks change from 2.5mm to 3.5mm. The standard for 12 volt triggers in the audio world has become the 3.5mm size and all new Parasound products will change to use this larger size.
Here's one more change to the rear panel. The ground lift switch has been removed. Changes to the internal grounding of the amps make this switch unnecessary.
To conserve energy and meet Energy Star and EU power consumption requirement NewClassic amps only require 0.5 watts in standby.
Updated front and rear cosmetics give the v.2 amps a fresh new look. The front panel has been updated with rounded corners, a new display lens, and updated silk screening. The rear panel has updated silk screening making it easier to read and understand the functions.
There's also a power specification increase. The original versions of the NewClassic amps were underrated. With the v.2 amps, Parasound has changed the specification to match the actual capability of each amp. There is an average rating increase of 10-15%. Both version 1 and v.2 amps have the same power and there are no changes to the audio circuits.
