On this blog, I will share my love with the world of Personal Stereos. This is limited only to Personal Stereos and Minidisc Players and maybe some other unique gadgets. The common rule with all those Personal Stereos is their State-of-the-Art; High-Quality Sound, Excellent build and Unique design - in other words, Personal Hi-Fidelity Analog music players for the soulful man. The main interest (but not limited to) in Walkmans is AIWA Personal Stereos from their early years' product line from 1984 to 1991. The main interest in Minidiscs (but not limited to) is Sharp Minidiscs. I will post pictures of rare Walkmans and Minidiscs with information. Thank God for making all this possible, I hope you all will enjoy my blog.
Note: I started this blog in 2011 to offer a unique perspective for educational purposes in the world of personal Stereo.

AIWA HS-PX10 Part II




HS-PX10 / HS-PX101 / HS-PX700
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

AIWA PERSONAL STEREO FOR PEOPLE WHO REALLY LOVE MUSIC.


1987 AlWA's HS-PX10 represents a true high fidelity breakthrough in headphone stereo.


Along with Dolby B, it also features the more effective Dolby C noise reduction system, found on expensive component decks, which dramatically cuts tape hiss for clear, high fidelity playback.



Hi-End AIWA models catalog
High fidelity playback is also enhanced by DSL-EX, a new version of AlWA's famous Dynamic Super Loudness. Not a tone control or graphic equalizer, DSL-EX is a circuit which varies both bass and treble equalization depending on the input signal level to achieve better frequency response over a wider range. The separate LOW and HIGH sliding controls enable adjustment of DSL-EX operation to better match headphone response and suit personal listening tastes.


The HS-PX10A version is supplied with a QUICK ONE HOUR rechargeable battery system to save time and money on batteries, delivering over 2 hours of playback from a 1-hour charge. The HS-PX10A can even be used while recharging.

"NO ONE GETS CLOSER"  - British AD from "Magazine" 1987. Indeed, The PX10 won a special award by the Good Design Award in Japan.
 
Tape playback features include feather-touch push button controls, remote control from the headphone cord, 3-way auto reverse (continuous/one cycle/manual), Metal (Cr02)/ Normal tape selector, bi-directional music sensor (1-selection), and full auto stop.

Pioneer PMD-R77



~~~~~ Pioneer PMD-R77 ~~~~~


MiniDisc [MD] is a magneto - optical disc-based data storage device initially intended for storage of up to 74 minutes and, later, 80 minutes, of digitized audio. In the form of Hi-MD, it has also developed into a general-purpose storage medium. MiniDisc was announced by Sony in September 1992 and released that November for sale in Japan and in December for the USA and Europe. The music format was originally based exclusively on ATRAC audio data compression, but the option of linear PCM recording was later introduced to attain audio quality comparable to that of a compact disc. MiniDiscs were very popular in Japan but made a limited impact elsewhere. {wikipedia}


Pioneer PMD-R77 - OEM version of the Sharp MD-MT821

The Pioneer PMD-R77 is a unique and very rare version of the Sharp MD-MT821. This MD was sold exclusively in Japan. Regardless of sound quality and features the PMD-R77 have a major issue. out of 3 players I had encounter all of them have a malfunction and displayed: "NO DISC" I believe the lens are the fault of this OEM version. the remedy for that is to replace the internal mechanism of the PMD-R77 with a working Sharp MD-T821 mechanism. this MD recorder is one of my favorite of my MD collection.
