I imagine you would do this in the software.

That really was something I wasn't aware of.

I had planned a little rack using the 4ms Pod with FH-2, one CV and one gate expander and ES-8. According to modulargrid, the power consumption is 397 mA +12V and 133 mA -12V

So I'm definitely not a pro audio person by any means, but isn't this a subjective call?

The data on the Expert Sleepers page is spec'd at 96kHz, maybe it draws less at lower resolutions?:

Maybe I need to rephrase the question...

Differences in features aside, is the ES-9 technically on par with an audio interface like the UA Apollo Twin MkII in terms of A/D and D/A conversion?

For the record, I plan on getting the ES-9 because of its suitability for sending and receiving several lines of audio and CV.

i have an ES-8 and i´m happy !
no need for more ins and outs for me.

just out of curiosity:
how do the ES-8 and ES-9 compare in regards vs. electronics, "audio quality on paper" etc.



@scrunday,
thats probably more to the studio people who might have to answer, .........or at least share their opinions.
For example ES-8 vs. a RME or so.

( interested myself to hear about)
(personally, the ES-8 is doing it for me ! As are the 200€ Audio interfaces )
For sale / reduced prices ( swiss (we are NON-EU)/ in case it makes sense_ EU/WW)(CHF +- = $):
WMD Geiger Counter: 180.- / Dotcom Q960: 700.- / Q119: 430 /
ATV A-Frame incl. Accu and Bag: 850.-, like new, quasi unused.

For some perspective here, a Pod40X is rated at 1400mA. A TipTop μZEUS is rated at 2000mA. People generally have more power available than was the case a few years ago.
The data on the Expert Sleepers page is spec'd at 96kHz, maybe it draws less at lower resolutions?
It's about 30mA less at 44.1kHz.

On paper they're pretty much the same.

Looking forward to adding this into my recording set up. Can you simultaneously monitor all 14 inputs through the 1/4" outs without going through a DAW?

Would be nice to eliminate my interface and ada8200. While this works... you can only monitor the inputs from the ada8200 when a DAW is open.

God i think a lot of us would kill for a 14in 8out adat eurorack interface.
I know bandwith with adats and chips is complex so it's probably one of the reason there are none.
I would prefer something else than having 2 es-6 for 12 IN and 2 es-3 for 16 OUT :deadbanana:

yep
although id be happy with even 8in/8out really
aggregating audio interfaces is a pain to me, and invites more issues. using a solid masterclock and adat makes much more sense in a studio situation.

although this es-9 can be used standalone, is kinda cool, and i suppose there is a growing market for people who dont have or need a typical audio interface setup.

I could never get the timing right with the es-8 on a pc with ableton, tempted to give this a try so it's all on one soundcard.

ASIO driver?

Post by ianross » Tue Sep 24, 2019 12:50 pm

Does Expert Sleepers offer an ASIO driver for this or do you have to use it with something like ASIO for all?

So no upgrade/add-on path then, eh? No chance to make it 32ch+ in one windows interface, I take it, since there's no ADAT port...?

I have a few questions before I'd be able to commit...

How well does it cope with balanced devices going in through the unbalanced inputs?

Is it possible to configure the balanced outs and headphone jacks for monitoring inputs whilst the ES-9 is not connected to a computer? For instance, are you able to configure say inputs 1 and 2 as a stereo pair, input 3 as a mono euro rack level input, inputs 4 and 5 as a balanced level electron box stereo pair, etc. Once that's all set up in the software, then turn the computer off and continue to monitor that configuration via headphones and a mixer?

Similarly, is it possible to configure the outputs to do anything whilst not plugged into a computer (pass through, merge of inputs, or similar)?

Sorry for slow replies - the forum stopped sending me notifications.

Only 8 at the moment. A firmware update may change that.
God i think a lot of us would kill for a 14in 8out adat eurorack interface.
ADAT is limited to 8 channels. If you have two ADAT pairs you can have 2x ES-3/6/7 for 16 in/out.

Yes.

As well as anything with unbalanced inputs. You're just ignoring one of the two signals.

Yes.

Looks hefty, and I'm sure the build quality is top notch, but I'll stick with my ES-8 for now. Just don't need that much I/O.

Yes. It's just audio as far as the computer's concerned.

.
if i read the manual right, you could monitor through USB all ins/outs

(nowadays, many computer but also standalone consoles have USB plug&play interfaces)

Yes, over USB you have all 16 inputs & 16 outputs.

Is there any difference in recorded audio quality coming from an es8 vs an es9?

I saw this in the es9 manual but not the es8 manual:
The input ADCs (analogue to digital converters) have optional DC Blocking filters, which can be
switched on or off in pairs. It is recommended to have these on if the input is being used for audio,
to maximise dynamic range and to avoid pops due to DC offsets in the recorded audio. The filter
must be turned off in order to use the input for CV.
