NAD 3225PE stereo integrated amplifier
NAD’s product philosophy can be summed up in one phrase: “high-value engineering". The compact and economical 3225PE integrated amplifier is conservatively rated at 25 watts / channel of steady-state power for sine-wave test tones, but with +4 dB of IHF dynamic headroom, its effective power for musical transients is considerably greater. Power Envelope design produces bursts of up to 60 watts / channel at 8 ohms and 80 watts / channel at 4 or 2 ohms, ensuring clear and authoritative reproduction of the impact and sparkle of live music. If you ever overdrive the 3225PE, Soft Clipping™ will prevent the harshness and gritty distortion that is caused by hard clipping in conventional amplifiers.
NAD’s impedance selector allows optimum performance to be delivered into any speaker impedance The 3225PE produces up to 15 amperes of peak current, delivering full power to impedances as low as 2 ohms. The quiet phono stage and wide-range line-level circuits, transparently reproduce even the subtlest detail of every recorded sound. Infrasonic and ultrasonic filters eliminate unwanted interference while preserving accurate response from 20 Hz to 20 kHz.
Musically effective tone controls adjust the deep bass and high treble without sacrificing clarity or midrange accuracy.
