The Parasound 2125 V1 is a powerful and flexible two-channel power amplifier designed to provide reliable performance across a wide range of stereo and home theatre systems.
Its Class AB design uses fully discrete circuitry and a high-current toroidal transformer, with the amplifier capable of delivering up to 35 amps of peak current per channel. It produces 125 watts RMS per channel into 8Ω and 200 watts per channel into 4Ω or 2Ω, while bridged mono operation provides up to 400 watts RMS into 4Ω or 8Ω
The 2125 V1 is THX Ultra2 certified and offers a range of integration features for both dedicated listening rooms and custom installations. These include switchable 20Hz/40Hz high-pass filtering, stereo or bridged mono operation, automatic turn-on via audio signal or 12V trigger, A/B speaker outputs and rear-mounted gain controls.
With its high-current capability, low-heat Class AB design and compact 2U chassis, the Parasound 2125 V1 is well suited to stereo systems, home theatre applications and custom installations where dependable power and installation flexibility are important.
