Alice Soundtech DA6-2 - XLR - Dual 6 Output Distribution Amplifier

Alice Soundtech DA6-2 - XLR - Dual 6 Output Distribution Amplifier

The Alice DA6-2 MKII is a 19” rack mounted high-performance, dual six output distribution amplifier designed to provide multiple audio feeds in stereo and dual mono applications. It can also be configured as a single twelve output distribution amplifier by the operation of internal links.

All audio connections are via professional standard XLR connectors and 25 way D-Sub. Both versions have their inputs via a pair of female Neutrik XLRs. Outputs are available in two options i) XLRs (12 x male carrying individual outputs) and D-Subs (2 x male 25 way D-Subs, one for left and one for right using the TascamTM wiring standard).

NOTE: This unit has XLR output connectors.

All inputs and outputs are electronically balanced and floating and may therefore be unbalanced individually if required (see below). Note that unbalancing any input or output has no effect whatsoever on the level or balanced nature of the remaining inputs and outputs, so any combination of balanced and unbalanced equipment can be accommodated.

The input impedance of the DA6 2MKII is factory set to 20K ohms but may be changed to 600 ohms through the operation of internal links. Audio levels may be adjusted via the multi-turn trim pots located on the front panel.

Connection of unbalanced equipment requires pin 3 of the XLR connector to be strapped to pin 1 (pin numbers are generally moulded into both plugs and sockets). The unbalanced connections are then made to pin1/3 (ground) and pin 2 (signal).
