Power, Features, Build, and Affordability
Parasound's New Classic Model 2125 is destined to be the company's most popular two-channel power amplifier. Its winning combination of power, features, build quality, and affordability make it a must-have for all but the most demanding systems. And the THX Ultra2 certification means that it meets the highest performance standards for convincing reproduction of movie soundtracks.
With its advanced and extremely efficient low-heat design, the New Classic Model 2125 runs cooler than previous Parasound Classic series models, making it ideal for rack or cabinet mounting. The newly designed power supply delivers all the voltage you need for transient peaks in musical programs and stunningly realistic special effects.
High-Resolution Power On Demand
The Model 2125 delivers the high-resolution power you need for big entertainment. It offers 125-watt-per-channel output at 8 ohms and 200 watts at 4 ohms. It will also deliver a huge 400 watts into 8 ohms or 4 ohms in bridged mono mode. And it boasts 35 amps of peak current per channel for superior resolution of demanding musical peaks. The sound quality is pure Parasound pleasure, of course.
Fully Discrete Circuitry
Fully discrete circuitry with a large toroidal transformer keeps the noise floor exceptionally low and the musical signal pure. The 'Class AB' circuitry provides efficient operation with less heat output than pure 'Class A' for the highest degree of reliability with DC servo and relay protection circuitry. Standby, channel status, and high temperature indicators keep you informed of the operation status.
Ideal for Custom Installations
The New Classic amplifiers have several features that make them ideal for custom installation. These include automatic switch on and off when the amplifier detects the presence or absence of an audio signal. It can also switch on and off via its DC trigger with looping output. The soft touch power buttons glow in standby mode.
The Model 2125 can drive and select two speaker pairs (or two mono bridged speakers) with two pairs of speaker terminals and speaker select buttons with relay switching.
Other features include handy rear-panel gain controls, a ground lift switch for helping eliminate system-induced hum problems, gold-plated RCA input jacks and loop output jacks, and heavy-duty 24K gold-plated five-way speaker terminals.
