If your machine starts up with the splash screen "MDS-E12" or "MDS-E10" then the Copyright/Original bits recorded will be the same as the source. If your machine starts up with "MDS-E12 PRO" or "MDS-E10 PRO" then the Setup menu contains a new item "Copy Bit" which allows you to set the Copyright/Original bits on the recorded track to either "Permit", "Inhibit" or "PreRecorded". Permit means the track can be copied digitally unrestricted, even using consumer decks. Inhibit means that consumer decks can't digitally copy the track and PreRecorded means that one generation of digital copy is allowed by consumer decks. In "Monitor" mode the SCMS bits output on a digital interface will be the same as the SCMS bits on the input. i.e. these machines don't operate as "Copy Bit Killers" on pass-through. One such device that can do this is the [[https://www.behringer.com/behringer/product?modelCode=P0141|Behringer SRC2496]] (although this is now a discontinued product). Other products such as Focusrite USB interfaces and some PC soundcards can also strip SCMS. Note: Some early machines, or machines from some regions may require an internal resistor modification to allow SCMS to be ignored. See the Service Manual Supplement-1 listed for the MDS-E12/MDS-E10 - a Serial Number range is given where the mod is required. This resistor mod does not make the machine "PRO" and the Copy Bit option will NOT appear in the Setup menu - this comes with newer firmware in the machine. The only sure way to tell if a machine is "PRO" is from the startup splash screen. If you can see inside, early machines tend to use Nichicon "Fine Gold" capacitors in their analogue sections. This usage seems to have stopped in the later machines which tend to be "PRO". ==== Some notes on AC input voltage ==== The Japan version of this unit is marked as 100VAC input only, however it seems that the AC board isn't very different between the Japan and other versions. Converting the unit to run on 120VAC is as simple as moving the yellow wire to the (UC2) solder point, 240VAC is the (CN2) solder point. This modification is supported by pages 77 and 81 of the Service Manual. In the service manual linked above, the connector on the AC Board for 100V is CN3 and the AC input is connected to pin 2. For 240V, if CN6 is not populated, then the connector CN3 is moved to CN6 and the AC input is connected again to pin 2. {{:equipment:sony:pro:mds-e12-ac-board.png?400|E12 AC Board}} {{:equipment:sony:pro:mds-e12_power_supply_mod_for_240v.jpeg?400|E12 AC Board - alternate version}} ====== Repair ====== Drive: MDM7SC (Type-R, CXD2662R) Eject belt: 17mm dia x 0.8mm square section (53mm circumference). e.g. [[https://www.ebay.co.uk/str/linxaudio|Linx Audio (eBay)]] [[guides:repair:e12-belt|Belt replacement guide]] ==== Firmware Bugs ==== Parallel port: If you have the "non-PRO" MDS-E12 (splash screen says "MDS-E12") then the Setup menu Parallel port behaviour for the REC and STOP settings are transposed. If you want the parallel input to be "STOP" then the menu item needs to be set to "REC". Conversely if you want the parallel input to be "REC" then the menu item needs to be set to "STOP". If you use the Parallel->Preset setting, then input 2 is REC (not STOP as labelled) and input 3 is STOP (not REC as labelled). This bug is fixed on the "MDS-E12 PRO". The upshot of this, is if you are using the parallel interface and using the preset settings you will get the same transport behaviour from both versions of the E12, namely input 2 performs REC and input 3 performs STOP. ====== Photos ====== Submit your own!
