Sum or mix up to 4 line level inputs

The FSR ASA-4 is a 4 x 1 audio summer that will sum or mix up to 4 line level inputs and provides one transformer coupled line level audio signal output. It features unity gain which means no input signal is attenuated as happens in any passive mixing device. The residual noise (<80 db) insures that the fidelity of the incoming signals is not compromised in any way. The ASA-4 has a transformer coupling of the output which insures that ground loop problems are completely eliminated.

The ASA-4 can handle both balanced and unbalanced inputs of both pro, semi-pro, and consumer audio sources. The unit is a 1/2 rack unit and comes complete with a rack mounting kit. This kit permits the installation of any two half rack units.

Accessories:

A free rack mount kit is supplied with each ADA-4 unit. The black painted, steel rack mount kit allows for your choice of table or rack mounting without additional cost. The wall mount transformer, also provided free with each unit, is 27VAC, @75ma, and is UL and CSA rated.
