NB. This product is currently under development.
This sound card, designed for use with the CDTV is largely based around the Melody 1200 Pro.
The analog output module is removed and CDTV's onbord logic and parts are used, no mechanical changes to the housing are required. This allows the original RCA outputs of the CDTV to produce both the native Amiga sound, as well as sound from the melody. o CD-ROM audio and Melody output are muxed (XOR) while Amiga is mixed any time o CDTV makes use of the same 18/16 bit DA-Converter used at Melody-Z2, no 20 bits engine (Melody 1200) but still nice performance. o 16 bit decoding of MPEG, no 20 bit raw-playback o as we don't want changes to the housing no sampling is supported. We're thinking of MPEG readback, but while CDTV is damn slow it should be useless and saves money if removed. The way it's done: o Melody CDTV comes with CPU-module (access to 68k's bus and some minor address decoding logic) but makes use of the same interconnection wireing bus like real Melody 1200 o Additionally it comes with audiobus adapter (access to mainboard logic and parts) o Software is activated via bootable CD or floppy after switch-on and probably embedded into ROMs at later stage (not nessecary best solution!) o It's controlled via hotkeys send out by the IR-Pad and a plain version of AMPlifier which works at Kickstart 37.999 (used at CDTV), too. Expansions: o Depending on interest Digital-IO done for A1200 could be used, too (output only). It would even add digital output for CDDA-CD playback. o The AMPlifier-Display project is intended for use with CDTV, too. As it will be announced at Aminet it won't be sold by Gruner Bürotechnik sales@katodev.de. Allthough the parts required my be ordered there. State of project: o Prototype was done and is going to be activated soon o Series takes a while primary because of software and licenses required o The price will be about that of a Melody 1200 plus offering some PRO features going to be the ultimate MP3 playback engine!
