Nakamichi 582 (1979–1981)

A cassette deck that a reviewer kept pristine for over a decade - not to listen through, but to measure tape with.

Overview

The identity needs untangling first. The Nakamichi 582 is a Nakamichi cassette deck, built by Nakamichi Corporation. It is not a TAD product. TAD (Technical Audio Devices) is a separate brand, and no source connects the 582 to it. File this deck under Nakamichi.

Nakamichi first sold the 582 in 1979 and discontinued it two years later, in 1981. That is a short run for a deck that went on to a second life as a measurement instrument. The manufacturer's suggested retail price was $890 (¥168,000 in Japan), well above the budget tier. It was a serious three-head machine for recordists who cared about what came back off the tape, not just what went onto it.

The 582 is a full-width component, not a compact shelf unit. HiFi-Stereo (August 1979, p.36) measured it at roughly 19¾ inches wide and 5⅛ inches high. The factory dimensions are 500 x 130 x 350mm at 8.3kg. The same review noted the headphone jack to the left of the cassette opening, a cluster of controls to its right, and an accessory socket for powering a microphone mixer or a wired remote.

Key Features

Dual-Capstan, Three-Motor Transport

The heart of the 582 is its dual-capstan drive, which reduces tape speed errors by gripping the tape at two points rather than one. Three heads - erase, record, and playback - mean you can monitor off the tape while recording, and the transport runs on three motors. Romanian listings sum it up as "3 capete, 3 motoare, dublu cabestan" - three heads, three motors, dual capstan. Wow and flutter is quoted at 0.05% in the common spec sheets, though audio-database lists a tighter figure of 0.04% or less Wrms (0.08% or less Wpeak).

Pressure Pad Lifter

One of the 582's more consequential design details is a pressure pad lifter on the playback head. It pushes the cassette's felt pressure pad away from the tape as it passes the head. The pad normally presses the tape against the head, and it is a source of inconsistency from shell to shell. Lifting it out of the equation lets the deck's own tension and head geometry do the work. It doesn't show up in a spec sheet, but it shows up in how consistently a tape plays back.

Full-Logic Transport Controls

The transport is full-logic, meaning the controls respond to the lightest finger contact rather than requiring a firm push. Function selection is fast and effortless, with cue and review available for locating passages.

Built-In Calibration Oscillators

Nakamichi built 400Hz and 15kHz oscillators into the 582, along with facilities for bias and Dolby level adjustments. That means you have the tones on board to align bias and Dolby level to the tape in the well, instead of guessing at calibration. The deck also carries double Dolby B noise reduction, quoted at a 66dB signal-to-noise ratio with Dolby B engaged.

Tape Handling and Response

The 582 accepts type I, CrO2, and Metal tapes, with frequency response quoted at 20Hz to 20kHz on Metal tape. Total harmonic distortion is listed at 0.8%, and line output at 1V. An optional remote control was available.

Historical Context

The 582 shares a power transformer family with the Nakamichi 482, 481, 480, 580, and 581, according to a parts listing. That helps anyone chasing a replacement transformer, but it says nothing about hierarchy or shared circuitry beyond that. A "582 Z" name appears in some listings as a separate designation. It should not be merged with the plain 582.

Collectibility & Value

The 582 has a modest but real following. A Reverb listing shows a used example in excellent condition that originally asked $486 and sold at $377. Single sales on a niche deck should be read as a range, not a price. An OLX Romania listing asks RON 4,500, and a Russian seller describes a 100V Japanese-market example as being in "amazing condition." The voltage is the question any buyer should ask: many 582s were built for the Japanese market at 100V, and transformer rewind services exist to convert them to 230V.

A capacitor rebuild kit for the 582 lists at $165. Marblehead Audio's "Ultimate Kit" replaces all electrolytic and tantalum capacitors. It comes with a warning: some Nakamichi decks suffer from "orange cap disease," a bad batch of polypropylene orange caps that such kits do not address. Belt and idler kits are also available. At least one owner has documented a motor defect requiring repair, so a careful listen and a transport check before buying is wise.
