Audac ATU44 universal input adaptor which

The AUDAC ATU44 is a universal input adaptor which can be used for a wide variety of connections and extensions. One of its possibility's is converting any loudspeaker signal into a balanced or unbalanced line level signal. It has inputs for 100V, 70V, 50V, 33V and standard 8 Ohm low impedance speaker signals.  It also offers the possibility to convert an unbalanced line signal into a balanced one, and vice versa.

The switch on the front panel allows selecting between converting a speaker signal into a line signal, or the conversion of an unbalanced line signal into a balanced line signal. The in's and outputs of the ATU44 are completely isolated by means of an audio isolation transformer. This makes the ATU44 the perfect solution for resolving hum and buzz problems caused by ground loops. The inputs are fitted with screw clamp connectors, and the output is fitted with a male 3 pin XLR connector.
