ADA MicroCab and ADA Ampulator handshaking question

[Toppscore]

Hi! Is anyone familiar with
the ADA MicroCab or the ADA Ampulator?

Are these preamps both straight DI units
that can/must ONLY output to recording mixers?

Or, can they be used within a rackmount chain of effects
towards adding tone/sound possibilities?

Can these two preamps output to an amp or another preamp
without recording/mixer board interaction or handshaking?

These two preamps are very interesting.
Thanks for any and all responses.

Well. I bought the ADA MicroCab. Has not arrived.
It is designed to signal to a mixer/recording application,
but my intention is to keep it within my rackmount
signal chain with a couple of rackmount preamps before
and some rackmount preamps after the MicroCab.

If this works out, I'll be interested in the ADA Ampulator.

Cheers.
