Very Good! All the diagram are easy to read, and its complete.

This was an excellent source of detailed assembly information on a device which is at least 12 years old. A very lucky find, coupled with great service.
;
Excellent Service Manual and best price on the Internet. This Service Manual covers everything you could ever need including full circuit schematics, component layout diagrams, stripdown procedure and full parts list/breakdown. I needed this to carry out a modification to one of these headunits and this manual covered everything I needed. Fast delivery, processed within a few hours.

Thought I would never find a copy of the Technics SX-EN2 Service Manual until I found Owner-Manuals.com. Price was very fair and I received the download promptly. While a photocopy, it is quite readable and includes all the pertinent information and diagrams. Thank you Owner-Manuals!

I really like this manual and it's reliable.I found and bought easly.thank you.
8575 N/B Maintenance
Two separate buses, Host-t-GUI in the width of 64 bit, and GUI-t-Memory Controller in the width of 128 bit are devised to ensure concurrency of Host-t-GUI streaming, and GUI-t-MC streaming. In PC133, or DDR266 memory subsystem, the 128 bit GUI-t-MC bus will attain the AGP4X or AGP 8X equivalent texture transfer rate, respectively. The Memory Controller mainly comprises the Memory Arbiter, the M-data/MCommand Queues, and the Memory Interface. The Memory Arbiter arbitrates a plenty of memory access requests from the GUI or AGP controller, Host Controller, and I/O bus masters based on a default optimized priority list with the capability of dynamically prioritizing the I/O bus master requests in a bid to offering privileged service to 1) the isochronous downstream transfer to guarantee the min. latency & timely delivery, or 2) the PCI master upstream transfer to curb the latency within the maximum tolerant period of 10us. Prior to the memory access requests pushed into the M-data queue, any command compliant to the paging mechanism is generated and pushed into the M-CMD queue. The M-data/M-CMD Queues further orders and forwards these queuing requests to the Memory Interface in an effort to utilizing the memory bandwidth to its utmost by scheduling the command requests in the background when the data requests streamlines in the foreground.
