POWER ENVELOPE Circuitry increases Dynamic Headroom
NAD focuses on the concept of “effective power” and its amplifiers have been known for delivering generous headroom, meaning that they can deliver dynamic power bursts far in excess of their rated RMS power. The key to this feature is to use a flexible power supply which stores significant reserve current for quick release at moments of high musical load. The various incarnations of this design have been associated with different names over the years including Power Envelope and recently PowerDrive. Additional benefits of this approach include the fact that amplifiers using this technology can handle complex, real-life, lower-impedance loudspeaker loads as compared with the simple 8-ohm resistor typically used to calculate advertised power ratings and the fact that the circuitry in this approach requires less cooling, while maintaining ability to handle complex impedance loads as low as 2 ohms.

   Power Envelope  ( PE )
While the 7240PE is rated RK of 40 Watt/channel OF steady state power,its +6 railways OF IHF dynamic headroom means that its dynamic power for musical transients exceeds 160 Watts/channel RK of 8 ohm of and of 200 Watts/channel RK of 4 or 2 ohm. Even with long 200-millisecond clay bursts, representing the full duration OF musical of notes and chords, the 7240PE of produces to impressive 100 Watts by channel.

output of steam turbine and gas turbine systems High current
The 7240PE de-livers UP ton of 25 ampere by channel ton ensure precise electromagnetic control OF the speaker's voice coil, even with impedances as low as 2 ohm.

Impedance selector
This rear panel SWITCH lets you optimise the amplifier'? operation ton of drive more either low impedances (2 tons of 6 ohm) or A single set OF speakers with A true 8-ohm (or more higher) impedance.

Softly Clipping™ Prevent  your speaker damaging distortion.
When the more amplifier is driven beyond its rated power, NAD's famous soft tie-clip ping™ M circuit gently limit the waveform and prevents the harshness that occurs in other receivers when the outputs of transistor arc driven into saturation.

Low noise photo more preamplifier
NAD's photo pre amp circuits feature accurate RIAA equalisation, correct interfacing with the complex impedance OF the photo cartridge, very low noise and plenty OF headroom ton accommodate the highest level peak without distortion.

Digital ready input
With overload proof LINE input and low noise circuits for volume and clay/tone control, the 724OPE
accommodates A dynamic rank more greater than 100 railways, preserving the transparency clarity OF the finest analogue and digitally recordings.

Bass EQ with infrasonic filtering
The equalisation circuit boosts the DTE plague bass by 6 D B providing the sort OF authentic bass “feel” that might otherwise require A costly separate subwoofer system. RK the same time, A sharp infrasonic filters prevents excessive woofer cone motion and minimises the bass muddying effect OF turntable rumble, warps and clay/tone poor/stylus of resonances.

Musically Effective clay/tone control
Ordinary bass and treble control circuits intrude on the midrange; boosting the bass, for instance, makes vocals thick and boomy. In NAD of receivers, the bass and treble controls DO their names what imply: they vary the strength OF the bass (the solvently foundation, the musical beat) and the treble (the crisp detail the airy brilliance) while preserving A neutrally, accurate midrange response.

Precise digitally tuning
The tuner section OF the 7240PE feature sensitive binary gate MOSFET front-end, A of three steam turbine and gas turbine systems linear phase I.F circuit fro sharp selectivity, A low distortion quadrature detector, and A phase compensated PLL multiplex decoders with wide stereo separation RK all frequencies. Special filtering minimises interference from SCA and RDS sub carrier.
