Headphone amplified made for teams requiring monitoring on up to three headphones in parallel.
Very sturdy case, similar to Sound Devices. Locking connectors.
Thing thing is made to take serious beating.
Works either from AA batteries or 5-17VDC external power (so, almost any external solution will do).

I don't see why you need such adjustments, as they must be done in mic preamp.

Wow, it's even packaged in the exact same reusable packaging as Sound Devices: plastic wrap on cardboard that you fold the flaps down on to secure the plastic wrap over the device.
I'll try to talk to them :-)
