Apogee Grand Documentation
Apogee Grand Documentation
I worked on the design of the Apogee Grand as a consultant for Apogee Acoustic. At the request of a Grand owner, I found my old documentation on the project and have posted it below. This information is provided "as is" and since it is 15 years old its accuracy can not be guaranteed.
The control system consisted of 4 Intel 8051 micro-controllers connected by a RS-485 network. There was one micro in each display unit and one micro in each control section. A cable connected the two speakers together for control information. It is possible to control the speakers from a standard PC using a RS-232 interface. There was once a Windows 3.1 (that's right!) program that controlled the speakers. Sorry, but I can't find the software.
The remote control was manufacturer by Universal Electronics and used a custom code set. If you lost your remote, you may be able to find an old remote manufactured by Universal Electronics on eBay. If you find one, remove the battery cover and you will see three holes on the circuit board. There was a kit that Universal Electronics sold which was used to download the Grand code set into the remote.
The brains behind the whole project was Andy Lewis who now works at Russound. Jim Raymond was the project technician who did the schematics, bill of materials and PCB. Mike Danielson did the analog circuit design. Todd Eichenbaum at Krell did the amplifiers.
