This used NAD 7600 as listed was purchased new by the current owner and includes the original installation guide, remote control unit, inner shipping container and outer box, as pictured. The unit is in excellent working condition in appearance and functionally. The 7600 is an integrated unit consisting of three top-of-the-line NAD components-the Model 2600 power amplifier, the 1300 preamplifier, and the 4300 tuner.
The receiver's preamplifier section features a switchabl...e moving-magnet (mm) or moving-coil (MC) phono preamplifier with extremely low noise levels. Its bass and treble tone controls, which NAD describes as "semi-parametric, " are fairly conventional center-detented knobs except that each control provides a boost or cut over a two-octave band centered at one of three selectable frequencies. The center frequencies were chosen for their usefulness in correcting for common response problems. The tone controls can be completely bypassed with a front-panel button. A switchable bass eq circuit provides a maximum 8-dB boost at 35 Hz, where most speakers need help, combined with a steep infrasonic cut that prevents overloading the amplifier or speakers at sub-audible frequencies.The receiver has high-level inputs for a CD player and a video sound source as well as full playback and recording facilities for two audio tape decks. Lever switches select tape-copying connections and the center frequencies for the tone controls. Small pushbuttons operate the other switching and selection functions as well as the balance control. Pressing the L or R button produces a smooth change of relative channel levels (a small light glows when the balance is centered). Each control button is clearly labeled to show its effect when pressed.Its tuner specifications indicate that the Model 7600 is a top-quality product, with at least one superlative rating, an image rejection exceeding 120 dB. The tuner section has a switchable FM noise-reduction circuit (FMNR) that automatically blends the stereo channels over the full frequency range, instead of the more usual high-frequency blending, at low signal levels. Except for the very weakest signals, which would not be listenable in stereo in any case, the sound maintains its basic stereo qualities, with some reduction in separation but a typical noise reduction of about 10 dB (roughly comparable to the performance of the Dolby B system in tape recording).Although the receiver has a digital-synthesis tuner section, the control knob's tuning action is much like that of an analog tuner. But it has several major advantages. The tuning is always precise, and the tuned frequency is always visible on the large numeric display. When the tuning control is close to a station, arrows show the correct tuning direction; an amber light goes on when the station is tuned correctly.The rear apron of the Model 7600 contains the usual input and output phono jacks, including preamplifier outputs and two sets of power-amplifier inputs, marked lab and normal. Removable jumpers between the preamp outputs and the power-amp inputs simplify the use of an external Model 2600 amplifier in bridged mode or of various signal-processing accessories. The normal amplifier inputs have 12-dB-per-octave rolloffs below 15 Hz and above 40, 000 Hz. In addition to the switched infrasonic filter in the preamplifier, these built-in rolloffs safeguard the system against overload from signals outside the audio range. Through the lab inputs, the bandwidth is 3 to 80, 000 Hz.
