Analog Multichannel like ProLogic and ProLogic 2 (II) which professional Models
All processor devices compatible to "AC-3" (Dolby digital) and DTS need for processing of analog stereo signals an additional integrated analogue to digital converter (ADC), which reduce the quality in sound by older movies and concert recordings, where the additional channels are implemented in the stereo channels.
Therefore I am looking for vintage professional equipment concerning "only analog" multichannel processing for surround sound home cinema applictions. I have found follow integrated circuits from various silicon manufacturers: Dolby Pro Logic ICs: Analog Devices (formerly SSM - Solid State Music) SSM2125 (Premium Grade), SSM2126 (Standart Grade) JRC - New Japan Radio Company NJM2177L NJW1102 NJW1102FG1 NJW1106 NJW1106FC2-80 NJW1106FC2 NJW1104 NJW1104FC2-80 NJW1104FC2 NJW1102A NJW1102AF1 NJM2177 [NJM2177 NJM2177A NJM2177L NJM2177AL NJM2177FB3 NJM2177AFB3] Micronas MSP34X2G 96kHz DIR + Dolby Digital / Pro Logic II / DTS decoder + Sub DSP MSP34X2G pdf, MSP34X2G description, MSP34X2G datasheets, MSP34X2G view ::: ALLDATASHEET ::: NPC - Seiko NPC Corporation SM5851AF Renesas/Mitsubishi M62463AFP M62462FP M62464AFP M69032P µÚÒ»¼þ×÷Æ· - ÒôÏìDIYÂÛ̳ - ÖйúÒôÏìDIY http://www.ic72.com/pdf_file/5pdf/M69032.pdf Sanyo Semicon Device LV1035M LV1041 Sanyo LV1050M virtual surround Sony Semiconductors CXD2719Q CXD2720Q-2 CXD2724AQ-1 CXD2724AQ-3 CXD2728Q Dolby ProLogic-II ICs: JRC - New Japan Radio Company NJU26203 NJU26203V NJU26203A NJU26203AV Mitsubishi Electric Semiconductor M62465FP Digital Multichannel integrated circuits YAMAHA CORPORATION YSS912C YSS932 Dolby Pro Logic Surround Decoder with Discrete 5.1ch Analog Input Sanyo Electric Co.,Ltd.
