I can try. (quoted info from Meridian PDF files + added comment)

IE16 = Digital Input Card IE16 (to replace ID10 or ID12) enables:
� MHR input from 800.
� Any 96kHz processing or output.
� Upsampling of 44.1 or 48kHz sources

Used in 861 up to v2.x, can be used in 800v3 for inputs.


OA00 - Analogue output card: 4 ultra-high quality outputs on phono. Effective
resolution: 24 bit. Contains ultra-lowjitter
master oscillators.

This is only 48 Khz i beleive.


OA20 - Analogue output card: 2 ultra-high quality outputs on both phono and
XLR (balanced). Effective resolution: 24 bit and 96kHz.

This is a card used in a 800 as player/preamp modell i think. Only for 2.x 800 modells?

ID12 - Digital input card: 5 SPDIF/IEC1937 cable inputs (32k-96kHz), 2 TOSLINK optical inputs. Two digital outputs;
bypass and Tape/2-room. This card
contains a DSP de-jittering system.


ID20 - Digital input extension: adds 2 SPDIF and 2 Toslink inputs.


Have no clue what a ID17004 is....
