Sony TA-E9000ES Home Page

by Espen Braathen

Breaking news: The service manual and the service manual supplement for the TA-E90000ES is now available for download.
Due to the storage limit set by my ISP I'm not able to offer the service manuals for the TA-P90000ES (5.1 analogue pre amplifier) and TA-N9000ES (power amplifier) at this point.

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 upgrade

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.

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).

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.
