Kenwood KX-1060 (1979)

A three-head, metal-ready cassette deck that sold for $450 and left the calibration to the owner.

Overview

The KX-1060 is a single compact cassette deck with a three-head transport and hand calibration for tape. Kenwood's own literature frames it as an answer to a specific problem. By the late 1970s, cassette decks were expected to compete with the rest of a separates system. The newest tape formulations, metal tape above all, only delivered if the deck's bias and equalization were matched to the tape in the well. Kenwood didn't bury that matching in fixed presets. The KX-1060 has a variable fine-bias control driven by a built-in oscillator that generates twin test tones at 400 Hz and 10 kHz. It switches between them automatically, and an LED shows which tone is active. The owner records the test signals, plays them back, and turns the control until they line up. Then he does it again for each new tape.

Kenwood published these numbers for the deck: frequency response out to 19,000 Hz on metal tape, a signal-to-noise ratio of 65 dB with Dolby engaged on metal, and wow-and-flutter of 0.045% WRMS. The flutter figure comes from Kenwood's two-belt drive system, the same transport arrangement the company used across its better cassette decks. The three-head layout is the other half. The record and playback heads are separate, and the playback gap is cut to an extremely narrow 1.0 micron. That lets the deck monitor off the tape in real time, so the user can compare source and recording by switching between the two. The narrow gap is also why the top end reaches 19 kHz rather than falling off well short of it, as two-head decks of the period routinely did.

The original asking price was $450 in the US market, a figure Kenwood itself used as the hook in its advertising.

Key Features

Variable Fine Bias with Built-In 400 Hz / 10 kHz Oscillator

Kenwood's advertising made the bias system the centerpiece. The pitch, repeated across placements in the audio press, was that plenty of decks at this price could play metal tape but only the KX-1060 could get the most out of every metal tape, and every other kind as well. The mechanism is a variable fine-bias adjustment fed by an internal oscillator producing test tones at 400 Hz and 10 kHz, with automatic switching between the two and LED indication. A separate equalization switch has three positions - Normal, Chrome, and Metal - so the record curve can be shaped to the tape category in use. The manual walks the owner through the procedure in detail. This is not a set-and-forget design, and the advertising leaned hard into the phrase "hands on."

Dual-Combination Three-Head Design

The three-head arrangement is not simply a marketing count. Record and playback have different requirements. A playback head wants the narrowest possible gap for sensitivity and high-frequency reach, while the record head has its own set of compromises, and the KX-1060 splits the duties accordingly. Kenwood's literature describes the playback head gap as an extremely narrow 1.0 micron. That is what lets the deck reach 19 kHz on metal tape instead of falling short of the audible limit the way a combined two-head design typically does. Because record and playback are fully separate, the user can monitor the recorded program as it is being laid down, switching between SOURCE and TAPE positions to check quality and set levels correctly.

Double Dolby Noise Reduction with MPX Filter

The KX-1060 carries a double Dolby system with individual circuits for recording and playback. The separation ties into the monitoring. The signal coming back off the playback head is fully Dolby-decoded, so what the user hears in monitor mode is what the tape will sound like on playback. Kenwood cites an improvement in signal-to-noise ratio of up to 10 dB in the range above 5 kHz. A switchable MPX filter is included for recording FM stereo broadcasts. It blocks the 19 kHz stereo pilot tone from interfering with the Dolby circuitry. A green LED indicates when Dolby is active.

DC Servo Motor Isolated from the Tape Transport

Kenwood worked to keep the motor's vibration away from the tape path. The literature describes the method plainly: a rugged, 12-rib rubber damper sits on either side of the motor to float it within the chassis. The claimed benefits are reduced resonance peaks, a lower modulation level, improved frequency response, and wow-and-flutter that holds up over long service rather than drifting as the machine ages. A special double back-tension system keeps tape tension even. Kenwood says this reduces frequency modulation effects and preserves frequency response in the three-head design.

VU Meters with Peak-Level LED and Memory Index

Average recording levels are shown on large VU meters. A fast-reacting LED indicates transient peaks above +6 VU, which helps because VU ballistics alone let sharp transients slip past. A memory index function returns the tape to the "000" counter position after recording or playback. It shuts off automatically and is ready for another pass, or it repeats playback if the user wants. Kenwood describes the combination of VU meters, peak LED, and tape monitoring as the route to optimum results.

Historical Context

Kenwood's own copy treats metal as the headline. The formulation's higher coercivity, retentivity, and remanence values are what let a cassette deck compete on audio terms with the amplifiers, tuners, and turntables of the day. The cost is a stronger recording field and, crucially, correct bias. The KX-1060's electronics and heads were designed around that requirement. The launch put it in front of readers of the major American audio titles. High Fidelity (February 1980, p.23) noted the deck's variable bias adjustment with built-in test tone oscillator, its double Dolby noise-reduction circuits, and the separate playback head that made precise monitoring possible. The same publication carried Kenwood's $450 advertising pitch on p.132 of the same issue, and Audio (December 1979, p.9) ran the identical campaign copy. HiFI-Stereo (November 1979, p.47) placed it as well. The same advertisement appeared across multiple titles and months, so this was a paid manufacturer campaign rather than an independent editorial verdict.

Collectibility & Value

Complete, working examples with the original manual are worth holding out for, since the bias calibration procedure is documented there and the deck is considerably less useful without it. There is no reliable data on spare parts availability or long-term service support, so buyers should treat the transport belts and the head assembly as the two areas most likely to need attention.
