SONY MU-D11 (1982) | Studiolabo System

 

Recording your own compositions and performances can be even more fun with the Sony MU-D11 multi-recording cassette deck. You can even record an entire quintet by yourself. Adding multi-track recording functionality to a cassette deck really expands the scope of sound play. The MU-D11 is equipped with a multi-track recording function. It allows you to play instrumental quartets and quintets by yourself, sing duets by yourself, create music using synthesizers, and create sound dramas with sound effects. The world of sound play is endlessly expanded. Of course, the basic functions are the same as a regular cassette deck. So you can play your existing cassette tapes, check recordings, and even copy tapes. Enjoy sound crafting with the MU-D11. The first step in multi-track recording is the duo. For example, if you have one guitar, you can create a simple duet by first recording the guitar to the left channel (track 1) and then recording the lead guitar to the right channel (track 2). This synchronized recording of individual tracks (sound with sound) is the easiest way to do double recording. If you play multiple instruments by yourself, it's several times more interesting. By repeatedly overdubbing (sound on sound) from track 1 to track 2 and track 2 to track 1, you can easily create multi-track recordings of three or more ensembles. By playing percussion, guitar, keyboards, wind instruments, and even vocals, you can record your own band performance on tape. Once you experience this fun, you'll never want to stop. The MU-D11 allows for multi-track recording using the same track system as a regular cassette deck or boombox. The heads for tracks 1 and 2 can be switched between playback and recording, and combined with the mixing function, you can record by yourself (or with friends, of course). After roughly locating the beginning of the tape in sync standby, the cueing mechanism rewinds the tape to just before the first sound is heard, so that the beginning of the recording is perfectly aligned. To operate it, simply press the lever lightly with your fingertip and slide it slightly to the left (opposite the direction of travel), and you will hear a clicking sound on the monitor. The studiolabo system even comprised a "recording cabin" for your home studio.

SHARP VC-S700 (1990) | 9-Head S-VHS Hi-Fi

 

Equipped with a 19-micron "Amorphous 9 Head" rotating head the S700 records high-quality images of long programs such as satellite broadcasts. Amorphous 9-head is an innovative imaging system developed by Sharp. It inherits the amorphous 9 head system from the S-800 for. By adopting a unique head, the image quality in 3x mode has been improved. Standard mode image quality is beautiful, and 3x mode image quality is almost as good as the previous standard mode. This allows for long recording times with high image quality. Amorphous is a material that maximizes the potential of Super VHS (S-VHS) tape. Amorphous is vapor-deposited onto ferrite, which has excellent playback characteristics. This material is used in triple-mode, which reduces head output. It demonstrates its capabilities by increasing recording and playback output and reducing signal noise (Y-S/N and C-S/N), resulting in clearer images. The ideal head width for recording and playback in 3x mode is 19 microns. Sharp's technology has made this possible. Two of these 19 micron amorphous heads have been added to create an amorphous 9-head video. Crosstalk has been reduced, and edge noise and color flicker have been reduced, resulting in high image quality in 3x mode that approaches that of the conventional standard mode. By switching the heads, even during slow/still mode, clean images with little noise are achieved. Standard mode, 3x mode, special playback, etc. The ideal head mechanism switches to the head best suited to each application. Sharp's unique amorphous 19-micron head produces high image quality. (Featured in the VC-S800 and VC-S700) An auto head cleaner maintains high image quality. Simply insert a tape and the head and drum are automatically cleaned, maintaining beautiful image and sound quality. 3-line logical comb filter: Accurate Y/C separation reduces color bleeding, dot interference, and color fading. Twin convex drum: Convex (protrusions) are installed at the beginning and end of the tape where it contacts the drum to suppress tape vibration and stabilize the tape's running, thereby reducing image shaking. External dimensions and weight: 430 x 106 x 407 mm 7.4kg

KEF Model 105 Series II (1979) | Reference Series

 

The KEF Model 105 Series II is a legendary Reference Series loudspeaker originally introduced in 1977 and widely adopted by audio laboratories and manufacturers as a benchmark for evaluating high-fidelity equipment. Building on the success of the original Model 105, the Series II incorporates significant technical improvements, advanced computer-aided digital analysis, and precision manufacturing techniques pioneered by KEF in the early 1970s. Each drive unit and crossover network is individually measured, digitally analyzed, and carefully matched before assembly, ensuring paired speakers differ by less than 0.5dB in frequency response and remain within 1dB of the original prototype across the full frequency range. The three-way design features acoustically isolated enclosures optimized for specific frequency bands, a curved and adjustable mid/high-frequency head assembly for reduced off-axis coloration and precise stereo imaging, and a redesigned bass enclosure engineered using modal analysis to minimize cabinet vibration and distortion. The B300 bass driver benefits from optimized 3-point mounting, improved internal bracing, enhanced acoustic damping, and mechanical isolation to reduce coloration and improve bass clarity. The integrated S-STOP (Steady State and Transient Overload Protection) system provides self-powered electronic protection against peak voltage spikes, thermal overload, and excessive low-frequency excursion, automatically reducing input levels when safe limits are exceeded and restoring normal operation once stabilized. Renowned for its neutral frequency response, stable stereo perspective, high output capability, and exceptional tonal accuracy, the KEF Model 105 Series II remains a benchmark vintage high-end loudspeaker for audiophiles, collectors, and serious hi-fi enthusiasts seeking reference-grade sound performance. Specifications: 965x415x455 mm | Weigth 36 kg | 300mm low frequency driver, 110mm mid-frequency driver, 25mm tweeter with Bextrene diaphragm | Impedance 8ohm | Power rating 200 W | Frequency response 30 to 25.000Hz
