Infrasonic Filtering Turntable rumble, floor vibration, tone-arm/ stylus resonance and radio interference. Such extraneous signals can impair an amplifierÕs handling of musical sound. They are likely to waste amplifier power, produce excessive woofer cone excursions, and may cause audible intermodula-tion distortion. The precise, minimum-phase, audio bandpass filtering in the NAD 1130 strips off such interference while preserving accurate response at audible frequencies, ensuring the cleanest possible amplification of the musical signal. If not desired, the filter can be bypassed. Bass EQ The NAD Bass Equaliser sharply boosts only the bottom octave of audible response, restoring the rolled- off bass of many recordings and effectively extending the useful deep-bass reach of many loudspeakers. The result is a satisty-ingly solid bottom end without boomy mid-bass. Musically Useful Tone Controls In the NAD 1130 the Bass and Treble controls have been designed so that, at moderate boost/cut settings, they provide musically useful corrections at very low and high frequencies at the same time the midrange from 300 to 1500 Hz remains essentially flat. Since high circuit impedances often add a subtle veil of noise to reproduced sound, the 1130 employs a quiet high-current tone control am-plifier stage with low impedances throughout. Digital-Ready Dynamic Range The 1130Õs Compact Disc, Video, and Tape inputs are fed directly to the Volume control, and so cannot be overloaded by high-level signal peaks. The 1130Õs total dynamic range exceeds that of the widest- range digital recording systems. High Current Output Buffer In addition to its conventional preamp output, the 1130 has a high-current output stage that can produce output signals of up to 15 volts, which are fed both to the front-panel headphone jack and to an extra set of Òhigh levelÓ preamp output jacks on the rear panel. With this circuit the 1130 can drive virtually all non-electro-static headphones to full output. And it can easily drive several power amplifiers in parallel, drive professional 600-ohm studio equipment, or drive the long connecting cables required for active powered loudspeakers or for remotely located power amplifiers. Designed for Value NAD stereo components have been praised around the world for their unusual combination of mod-est pricing, uncomplicated controls, advanced engineering, and state-of-the-art sonic performance. The NAD 1130 preamplifier is squarely in that tradition. For accuracy, for freedom from noise and distortion, for transparent and supremely musical sound quality, the 1130 is unmatched in value.
