The Sony TA-E9000Es is a high performance AV Control Amplifier. This page has been made to discuss the features and the technical details of this product. The information is sourced from the users manual, a nice brochure made by Sony and other sources.

The TA-E9000ES features 2 of Sony's newly developed 32-bit DSP LSIs designed especially for Digital Cinema Processing, allowing you to experience the full impact of 3 of Hollywood's leading dubbing theatres with as few as 2 speakers. A separate 32-bit DSP enables exceptionally accurate decoding of three of the most advanced multi-channel formats available - Dolby Digital, dts and MPEG Multichannel.

As of this writing the TA-E9000ES has been more or less discontinued by Sony. A replacement named TA-E10ES have been rumored to be in the works, but the launch of the new control amplifier has been indefinitely delayed. Don't expect any news on the TA-E10ES until 2003, if ever... Also, the model name may very well be changed if Sony ever decides to release a new surround pre amplifier. At the moment it looks like Sony is concentrating on making integrated home theater amplifiers instead. Personally I have now switched my surround processing duties to the Denon AVR-5803 (aka AVC-A1SR in Europe) THX Ultra2 A/V surround amplifier.

Spesifications and features

Rear panel

The Sony TA-E9000Es supports 5 audio source products and 6 video source products. The control amplifier supports both composite and s-video switching on all video product inputs.

Firmware upgrades

The firmware in the Sony TA-E9000ES can be upgraded by connecting the RS-232C port on the back panel to a serial port on a PC with a suitable inter-link cable. The binary firmware data is then downloaded to the TA-E9000ES by a supplied FLASH overwriting program (included in the zip file below). The firmware for the display, control and decoding sections can be upgraded separately, however they are usually upgraded at the same time. The upgrade takes about 5 minutes at a baude rate of 56700 kbps.

Send me a mail at to receive the CD-keys. Please use "E9000B" as the subject (automatically selected if you use the link above). If you don't use this subject the mail might get lost in my inboxes! You will usually receive the CD-keys within a couple of days if you observe this simple rule. As before the VUCD-E9000A user manual will give you the details on how to perform the upgrade in a safe manner.

Official Upgrade Kits for the TA-E9000ES


The VUCD-E9000A kit consists of a CD-ROM disc with the version 2.01c firmware, a RS-232C cable and a new remote control (RM-SU1). Retail price in Japan is 15 000 yen. In my opinion the kit is not worth the asking price just to get the new remote. The RM-SU1 is a rather simple remote and it's a shame Sony could not come up with something more serious for the high price they charge for this kit (100 to 150 USD).

The RM-SU1 remote can apparently be ordered separately as a spare part using the sony part number: 1-476-402-11. Warning: I have aquired this information from a third party source and can not make any warranty on this claim.

VUCD-E9000A Upgrade Kit


The VUCD-E9000B kit consists of a CD-ROM disc with the version 2.5 firmware. This adds the capability to decode MPEG-2 Advanced Audio Coding (AAC). This is important in Japan as the local digital satellite brodcasting uses AAC as its audio CODEC. More details on AAC can be found at the official AAC web site: The retail price for the "B" kit in Japan is 15 000 yen.

Common faults

Power board:
The power supply is the main culprit for most of the TA-E9000ES failures. Symptoms of this are no sound and a very dim or no display. Apparently the power board has several weaknesses which have caused Sony to supply a modified version in later production units.

The circuit around transistors Q108 and Q109 are prone to oscillation, which will cause one or both transistors to break down, as well as resistor R124. This resistor is originally a surface mounted device capable of 1/10 watts of heat dissipation. The modification suggested by Sony is to replace this 4.7 k ohm resistor with a 1 watt rated version. Also, to prevent further oscillations a 100 pF capacitor is added in parallell with R153.

(Some suggests that also transistor Q110 is a candidate for replacement.)

The US issued service bulletin from Sony suggest that this fault may occur with units having a serial number in the range 800001 - 802746.
Serial numbers 80#### are for the US/Canadian version.
Serial numbers 50#### are for the european version.

Digital board:
I personally have an european version of the TA-E9000ES (serial number 500609). While my unit have been free from the power supply failure, another strange failure was noted after I upgraded to the version 2.01 software with virtual EX. Most of my listening are done using vanilla Pro Logic, Dolby Digital or DTS modes. But with the virtual EX decoding in place I was eager to try it out. However, as soon as I selected any of the Sony proprietary virtual multi dimension modes a lot of static noise could be heard from the speakers after a initial heat up period. As I seldom use these modes I did not bother to get it fixed.

It was not until I read the HIFI1-99-011 service bulletin that I discovered that I was not the only TA-E9000ES owner with such a problem. The service bulletion suggests that all the three S-RAM chips (IC2007, IC2010 and IC2013) used by the two Sony DSP's need to be replaced if this problem occurs.

Unfortunately, the 3.3 volt 128Kx8 Static RAM chip 71V124-15Y from IDT is no longer available from the manufacturer (however, Sony might have it avilable as replacement part 8-759-482-20).

The IDT web site suggest that the 71V124SA can be used as a replacement. Apparently this is a eqvivalent SRAM device (which also supports higher speeds).

So if your TA-E9000ES begins to make static noises you will need 3 pcs of IDT71V124SA-15Y (SOY_32_Y package) and the right tools and experience to do the de-/soldering job.

Technology overview

The Sony TA-E9000ES features a Analog Devices 32-bit SHARC DSP for decoding of multichannel audio formats (Dolby Digital, dts, MPEG, Pro Logic) and two Sony 32-bit DSP processors (CXD2712R) for Digital Cinema Sound processing. The volume control operates in the digital domain.
