Much greater output voltage range - up to 9x more than directly connecting a DC-coupled interface via a 'floating ring' cable.
Would a DC coupled interface also get this increased range if connected via the ES-1? (it's implied but I want to know for sure)

Yes, that 9x is specifically referring to DC-coupled operation.

The gain of the ES-1's amplifier is 4.5x. The extra factor of 2x comes from the balanced input stage, and only applies if your audio interface has differential balanced outputs.

Ah, I see. Thanks! And good idea to take it out of that pre-order thread, I wasn't thinking when I posted in there. :oops:

follow up on this

would it only get the positive voltage and need an offset or would it gain for both positive and negative voltages

or am i missing something

When used as a DC-coupled amplifier, the ES-1 works for both positive and negative voltages.

Do all MOTU interfaces have differential balanced outputs? The Expert Sleepers website only makes specific reference to the Ultralite series. Is this also the case for the 828?

I'm pretty sure it does, yes.

Someone else on this forum must actually own an 828 though and will be able to confirm.

I had a 828 Mk2 and it was DC Coupled. Worked like a charm with silent way.
