The KD-D4 has plenty features. Some features, in early 80's most decks never even heard of. There are multiple tape counter functions, the display also showing either elapsed or remaining time. There is the Super ANRS noise reduction, adding to the Dolby B noise reduction. Programmable music scan, and rec mute functions, too.

The most curious feature is the spectro peak level indicator, having five display bars for various frequency ranges in the recording. The recording level display itself, besides the two standard level bars also carries an extra bar, displaying the level with supposedly both channels summed up [who needs this bar, either?]. Unfortunately, the bullish display cannot change the fact, the recording level indicator itself has insufficient resolution, while also lacking peak hold.

In all, there are 20 controls in the front plate, 17 of them push-buttons. For the gizmo freak, the KD-D4 is a daydream. The deck also provides 6.3 mm microphone jacks. Then again, lacks level adjust to the phones output.

Does the deck perform, then. Frankly, not good enough to make the audiophile primary deck. Also, the Super ANRS noise reduction is rather useless, sort of compressing the audio and turning the high tones metallic.

To the build, the KD-D4 feels heavy and solid. And, yes, it looks cool.
