   NAD   7240PE stereo receiver  - charcoal grey :                 

   The 7240PE receiver consists of the 3240PE integrated amplifier, with its vast reserves of clean, solid power for the the wide dynamic range of modern recordings, plus an exceptionally sensitive digital tuner
   Power Envelope design :
   While the 7240PE is rated at 40 watts per channel of steady-state power, its +6 dB of IHF dynamic headroom means that its dynamic power for musical transients exceeds 160 watts per channel at 8 ohms and 200 watts/channel at 4 or 2 ohms. Even with long 200-millisecond tone-bursts, representing the full duration of musical notes and chords, the 7240PE produces an impressive 100 watts per channel
   High-current output stage :
   The 7240PE delivers up to 25 amperes per channel to ensure precise electromagnetic control of the speaker’s voice-coil, even with impedances as low as 2 ohms    Impedance selector :
   This rear-panel switch lets you optimize the amplifier’s operation to drive either low impedances (2 to 6ohms) or a single set of speakers with a true 8-ohm (or higher) impedance
   Soft Clipping™ :
   When the amplifier is driven beyond its rated power, NAD’s famous Soft Clip-ping™ M circuit gently limits the waveform and prevents the harshness that occurs in other receivers when the output transistors arc driven into saturation
   Low-noise phono preamplifier :    NAD’s phono pre-amp circuits feature accurate RIAA equalisation, correct interfacing with the complex impedance of the phono cartridge, very low noise and plenty of headroom to accommodate the highest-level peaks without distortion
   Digital-ready inputs :
   With overload-proof line inputs and low-noise circuits for volume and tone control, the 724OPE accommodates a dynamic range greater than 100dB, preserving the transparent clarity of the finest analogue and digital recordings
   Bass EQ with infrasonic filtering :
   The equalisation circuit boosts the deepest bass by 6 dB providing the sort of authentic bass “feel” that might otherwise require a costly separate subwoofer system. At the same time, a sharp infrasonic filter prevents excessive woofer-cone motion and minimizes the bass-muddying effect of turntable rumble, warps and tone arm / stylus resonances
   Musically Effective Tone Controls :
   Ordinary bass and treble control circuits intrude on the midrange; boosting the bass, for instance, makes vocals thick and boomy. In NAD receivers, the bass and treble controls do what their names imply : they vary the strength of the bass (the solid foundation, the musical beat) and the treble (the crisp detail, the airy brilliance) while preserving a neutral, accurate midrange response
   Precise digital tuning :    The tuner section of the 7240PE features sensitive dual-gate MOSFET front-end, a three-stage linear-phase I.F. circuit for sharp selectivity, a low-distortion quadrature detector, and a phase-compensated PLL multiplex decoder with wide stereo separation at all frequencies. Special filtering minimizes interference from SCA and RDS sub-carriers
   FM Noise reduction :    NAD’s unique FM noise-reduction circuit eliminates much of the noise and distortion in weak FM stereo signals, a welcome improvement for any listener who can’t put up a roof antenna. With FM-NR, the 7240PE needs only half as much signal strength as other receivers to obtain good quieting. The thoughtful engineering of this NAD receiver is evident in the design of its logical, easy-to-use controls -and in the deliberate avoidance of glitter, gimmicks, and frills. When you choose an NAD receiver, you are investing in quality behind the front panel - in advanced circuit design, selected parts, oversize high-current transistors, exacting quality control, and solid construction for long-term reliability. The proof is in the listening
