Pushing the play button repeatedly toggles the play mode (normal, repeat, random).

Reviews:

Features: Appears to be clone of the Casio XG-3. Top (clamshell) disc loading. Uses one AA battery or AA-shaped NiMH rechargeable battery (included) Backlit in-line remote. Unit has all controls on remote, main body has only "hold" button and "open" slider. Two level Bass Boost. Battery save feature (the 10 sec. buffer is switchable to autoPS (auto power save, or buffer off) or PS off (buffer on)). Includes headphones (standard style, not ear buds seen in Best Buy ads), drawstring bag, and AC adapter for playback and in-unit battery charging.

Variants: Unit has been rebadged and sold by several others, including Goodmans (UK) who sold it at two different times, each with different model numbers(!) (the GMD16RB and MD100).

Mis-features: No recharging while playing, no "mono" indicator on display (but plays mono discs fine), 3 (!) hours on an LR6 (AA) battery, 5 on the NiCad battery (?!).

Links: Apparently imported (and manufactured?) by Venturer Electronics 725 Dennison Street, Ontario L3R 1B8 Canada. Unit appeared in a Best Buy advertising flyer. Best Buy sells the MDP1 for $79 (for a brief period of time in November 2000, the unit was available for $49 with free shipping!).

User comments: Upon listening, it sounds great, plays great, and is pretty good all-around. My only gripe is that is has pretty short battery life. For anyone who is just getting into the MD hobby, or a budget-minded pro who wants a travel companion, this is the unit to get! If anyone would like to contact me, I can be reached at [email protected]. -Dave Cruz

Features: ATRAC 3.5 (CXD2536CR), sound quality reportedly among the best of the MD players. EL-Backlit LCD remote displays: up to 6 characters of title information, volume setting, remaining battery, repeat mode (1/all), as well as animated "running indicator" of spinning disc in 3D perspective. Remote uses shift key to reduce remote button count, for example: volume and display controls use the same keys. Normal stereo mini-jack for headphones (like the Sharp units). Battery life: 9.5 hours continuous playback on Lithium Ion rechargeable, 20 hours when combined with 3 alkaline cells (using separately available drycell case). 3 step digital bass boost. Unusual double jack for headphone/remote. Batteries charge in unit when connected to AC adapter. Uses Kenwood NB-L9, which is apparently OEM of Sony LIP-12 battery. Available in black or silver accent colors (case is silver). No English summary in operating manual. Unit is unique to Kenwood.

Precaution: Manual states: ``This unit is designed for domestic use only, and it is very dangerous to use the attached AC adapter abroad. Never use it outside of Japan.'' (However, if you have some other way to charge an LIP-12 (using an MZ-R2, MZ-R30, etc), then no problem).

Misfeatures: No shuffle play mode.

Features: Panasonic's first MDLP unit. World record breaking 104 hour battery life. Power cut alarm signals "pi-pi-pi-pi" for 2 seconds, 3 times, before power goes out.

Announcement commentary: (courtesy Leon) Audio section has identical spec to all Panasonic portables since the MR200 (3.5+3.5mW, 2-step S-XBS). Size is identical to the earlier MJ80 (12.7mm thick). Like the MJ80, it is possible to attach a hand strap to the MJ78. The MJ78 also has "smart change" (draws in disc when the lid is pushed closed, and one-touch eject). It seems that the MJ78 doesn't come with the charging stand - the specs say you need a separate adaptor in order to use AC power.

User Comments: I've taken apart my Panasonic MJ30 and MJ75 and was able to dig up some info on the web about the chips I saw. On each of these units, there's a Sanyo chip set (decode-only ATRAC chip and "RF head amp", as listed on press releases), and a Panasonic chip (listed simply as microcomputer). The first Sanyo chip set documented online has ATRAC chip LC89640, and was announced in November 97. The set that has LC89641 was announced in September 98. While the older set consumes 120mW when in use, the newer set only consumes 46mW. These Sanyo chips all incorporate digital bass boost. However, they don't include the DRAM for shock-resistant purposes. Instead, they support external DRAMs. The MJ30 has the LC89641 set. The MJ75, meanwhile, has a LC89642 set. Info about the MJ75's chip was not found online, but it's probably another evolution. The specifications for the microcomputers have also been found. The MJ30 uses MN101C15C, which has RAM 2048(x8bit) and ROM 48K(x8bit). The MJ75 uses MN101C28D, which has RAM 2048(x8bit) and ROM 64K(x8bit). I'd like to mention that the MJ75 takes apart really nicely. Remove the screws that hold the bottom cabinet, then the unit can be split into three parts: bottom cabinet, chassis, top lid + disc holder. No small bits and pieces to worry about. The circuitry/mechanism is also uncluttered, almost elegant. -Leon

The Panasonic NiCd 1.2V 600mAh which came with the UK version of Panasonic SJMJ-75 and the Panasonic NiMH 1.2V 1400mAh that came with the Panasonic SJMJ-70 are compatible with the Sony MZ-R/E900. Both can be recharged on Sony's charger and vice versa. Sony's own NiMH 1.2V 1350mAh battery can be used on Panasonic models and charger. Jon Choo

Comments: The MJ5 has a matt finish front, similar to the Sony MZ-E30/E35. The MJ7 has a special finish, made by engraving many narrow concentric grooves (some frying pans have this circular groove design on their bottom), then coating it. However, having the MJ7 I wish I'd gone for the MJ5, as the coating is now a mass of scratches and dull patches (despite keeping the MJ7 in the protective neoprene bag). It looks like someone's been ice skating on it! The back of the MJ7 is the 'matt' style finish (same as the MJ5 I'd guess). -Martin Clinton

Car adapter (AD-S50CK - separately sold) resumes play at beginning of last song in play when car is started. Katakana/roman display. Unit charges simply by placing in recharger base (like a portable phone).

Features: MDLP capability, extra long remote cord, 40-second anti-shock protection (160 second protection in LP4 mode). Has the ability to alert the user to an incoming cell phone call (see explanation below).

User Notes: According to Sony's site, the cell phone alert function only works with the Japanese domestic protocol of CDMA, one of the largest cell phone networks in Japan (PHS being the other one, which is not compatible). It works by having CDMA built into the E600, then the MD player can recognize the signal patterns of CDMA-incoming calls to a device within close proximity (in this case, probably 1.5ft), then it plays a beep through the MD's headphones to notify the user. --Jason Kwan
