As so often happens with advances in audio technology, new features are first incorporated in top-of-the-line separate components which are beyond the reach of all but the most affluent of audio enthusiasts. Later on, these features filter down to high-powered, high-priced all-in-one receiv ers, where a larger audience is potentially available. Finally, they are incorporated into relatively low-cost, medium-powered receivers that just about anyone interested in good sound can afford. The Denon DRA-400 is a good example of a receiver which has benefited from technology first found in higher priced units. This receiver employs crystal-controlled, frequency-synthesized tuning for accuracy and has a five-station preset capability with battery-operated memory backup. Not only does the phono preamplifier section incorporate both moving-magnet and moving-coil inputs (the latter at an input impedance of 100 ohms), but the phono preamp-equalizer section has a direct-coupled input. The power amplifier section employs a non-switching biasing circuit for the elimination of so-called switching and notch distortion at the output stages. These refinements would have been found only on more expensive components just a few years ago. The front panel of the Denon DRA-400 is neatly divided into highly functional upper and lower sections. The upper section contains the power on/off switch, a numeric display of station frequency, a stereo indicator light, a signal-strength LED indicator, up and down tuning buttons, the five preset buttons and their memory switch, program selector pushbuttons, and a large, rotary master-volume control. The signal-strength indicator takes the form of a go-no-go indicator, rather than a signal-strength meter: It lights when the incoming signal strength is deemed adequate and does not light when weaker signals are received-an interesting approach but not very useful. Controls in the lower section are normally covered by a swing-down hinged door, since they are used less frequently than those just described. Behind the door panel are a stereo headphone jack; a pair of speaker selector buttons; bass, treble and balance controls; a three-position monitor/ copy switch; a subsonic filter switch; a stereo/mono switch (associated with FM reception); an MM/MC phono switch, and a loudness on/off switch. The rear panel of the DRA-400 is equipped with the usual 75- and 300-ohm FM antenna terminals, phono and high level input terminals, two pairs of tape in/out jacks, two pairs of color-coded speaker connection terminals, a chassis ground terminal, and a pair of a.c. convenience outlets (one switched, one unswitched). Instead of the usual AM loop stick antenna, a more elaborate, true AM loop antenna is packed with the receiver as a separate item; its two leads must be connected to the appropriate AM and ground terminals on the back of the set. The pivotable loop antenna is best snapped into an antenna holder during receiver installation so the antenna can still be rotated for best AM reception. Since this loop antenna forms part of the input-stage tuned circuit, the owners manual suggests that even if an outdoor AM antenna is used (because of inadequate signal strength), the loop antennas leads should remain connected to their appropriate terminals, in parallel with the outdoor antenna leads. Tuner Measurements Usable mono FM sensitivity fell short of published claims, measuring 16 dBf (3.47 V across 300 ohms). In stereo, sensitivity was limited by muting and stereo thresholds, which were set to 32 dBf (21.9 V). For 50-dB quieting in mono, an input signal strength of 19.5 dBf (5.2 V) was required; for stereo, a signal strength of 42 dBf (69.2 V) was needed. Plots of quieting and distortion (at 1 kHz) versus signal strength are shown in Fig. 1. Signal-to-noise in mono, at 65 dBf of input signal, measured 75 dB as claimed; in stereo it was 72 dB, also exactly as claimed. Harmonic distortion in mono measured 0.17% for a 1-kHz signal, modulating the r.f. carrier by 100%. Total harmonic distortion actually decreased to 0.085% in stereo for the same signal and modulation levels. Distortion in mono and stereo for other audio modulating frequencies is shown in Fig. 2. Although measured distortion was low at high frequencies in stereo and mono, I must point out that these figures were obtained using a bandpass filter with a steep roll-off above 15 kHz (the highest broadcast program frequency). Without the filter, subcarrier products were only some 42 dB below 100% modulation levels.
