Housed in a 3RU chassis with internal power supply, a single DN1248 Plus provides twelve input channels, each feeding four outputs, two of which are electronically balanced and two that are transformer isolated.
The "FM" version combines the advantages of both the "DP" and "AT" models, providing transformer balancing for all 48 outputs, as well as a second, linked internal PSU for auto-backup purposes. The unit can be retrofitted to the multipin connector and input/output configuration of the user's choice.
Outputs 1& 4, as well as duplicates of all the inputs can be found on the rear of the unit. The microphone preamplifier is a Midas Heritage series unit, specially adapted to the task and providing all the great sound and headroom for which Midas preamps are world famous.
