Title says it all. I've got 10 i/o with ross martins spdif thru focusrite 18i8.
At 96 k I can add 4 more input only via adat according to manual.
Any suggestions. As well as a dedicated converter was also thinking aphex or Yamaha etc. Could look at preamps with adat.
Keen to hear ideas

Seems apollo does it ( actually 8 channels ? ): help.uaudio.com/hc/en-us/articles/209496906-Using-External-Digital-Gear-With-Your-Apollo-Digital-Clocking-Primer-ADAT & S/MUX A single ADAT cable (TOSLINK) in each direction is all that is required to pass 8 channels of digital audio at sample rates of 44.1 or 48 kHz.
However, 2 cables are required in each direction to achieve 8 channels at 88.2 or 96 kHz, or 4 channels at 176.4 or 192 kHz. You can just use 1 cable each way if 4 channels is enough at 88.2 or 96 kHz or 2 channels is enough at 176.4 or 192 kHz. Please note that the secondary device will also need to support the S/MUX protocol in order to function as expected at higher sample rates. |

I'm using the M-Audio Profire 2626 for 4 channels of ADAT at 96k

Behringer AD8000?
I use two of them from the ADAT outputs on my SSL alphalink as the D/A for my headphone system and the A/D for talkback mics and drum trigger inputs.
But be aware that using 88/96 drops the 8 channels down to 4 channels so you'd need two of these boxes in parallel with two sets of adat optical cables in parallel to get 8 channels.

ADA8000 is 48k limited. MOTU 8A will work as a stand-alone converter for 8 i/o up to 48k and 4 i/o up to 96k over adat. motu.com/products/avb/8a |

Sort of stated on another thread, I have a BRC, 3 ADAT's, TosLink & other type cables (audio +4 snakes), AMPEX tapes (in unopened & wrapped boxes) all in mint condition (barely used). Never have had any of it for sale. If anyone's interested, PM me.

Lucid 88192 is the best of the lower price range. Apogee Symphony mk1 8x8 can be had very cheap if you look around as well.

you're using a focusrite 18i8 - you can buy a focusrite octopre pretty cheap. i have an octopre dynamic - does smux 8 44.1,8 48, 4 96k, 2 192k. the one i have is like 300 bucks now, cheaper without the compressors (but why?) Or you can get the new one which has the newer converters in the clarrett range that also sound great, around 500.
definitely an upgrade for your 18i8!

Those would probably be the “special” Ampex SVHS for the ADAT, you know 30 year old SVHS oh the fun. |

The ADA8000 doesn’t help as its dropping samples effectively..it’s not multiplexing the signal.
The MOTU 8A is probably the way to go for me

i'll keep an eye out for the units mentioned thanx to all.
in the mean time the rma pcm4222 adc has hiss at 96khz and changing filter settings doesn't get rid of it. i might start another thread bout that.

I'm using a Presonus DP88 for 4 channels at 96K right now into my Apollo Twin.
Sounds as good or better than anything I have ever used.
It's a shame 4 channels are not being used, but, what are you gonna do...

Audient ASP880 or ASP800 do smux.
I have the 880 hanging off my apollo optical in and they are great. I clock the Audient off the Apollo. Im using 8 channels at 48k but manual says they do 4 channels at 96 with 2 x optical cables.
Great pres for the money.
EDIT: Correction, it was not clear from the simple Audient manual but the Sound on Sound manual explains that you get 8 channels at high rates: “The upper lightpipe port provides eight channels at base sample rates, and channels 1‑4 at double sample rates. The lower port comes into play for double sample rates, when it carries channels 5‑8.”

With RME cards playing with different card slots can in some instances can remove noise yrmv. |
