info on Marantz PMD670
hello all-
our station bought 7 PMD670 decks under a grant from the CPB to accomplish regional recordings of community people and events. the PMD670 suits our needs well but i have uncovered a defect. on all of our 7 units, the rechargeable nicad battery (RB1100) runs down overnite when the unit is unplugged from the AC charger. Marantz tech support was able to duplicate this problem and is working with the engineers in Japan to find a solution. if the problem is in the software, the customer can update this themself but if they find the problem resides in the firmware, the units will have to be sent into Marantz for a firmware update. according to Marantz, they watched the battery discharge pattern on the oscilloscope for 5 hours straight and they confirmed that the unit does not enter "sleep mode" after the AC charging plug is removed. they have discovered that if the unit is unplugged, then powered up, then shut down the decks will enter sleep mode and the battery will not be discharged. the battery can also be removed from the compartment to retain the charge. i am pleased to report Marantz took my report of this problem very seriously and has every indication of resolving this issue within a short time period. the service techs at Marantz have been personable to me, actually talk to each other within the department and know me when i call. it is easy within their service department to get directly connected with the engineers who have worked on the design of these decks and they will answer questions with enthusiasm. pretty darn impressive for a company nowadays. they have promised to email me as soon as the solution is found and if it turns out to be a software issue, will send me the program directly. they sent a confirmation email to ensure they had my email address correct. -dan |
