Introduction
This section briefly describes the possibilities of the Q2TR – Q4TR transformer unit.
he Q2TR – Q4TR transformer unit is developed as an easy to use, flexible solution.
During the development of the Q2TR – Q4TR transformer unit, the AUDAC-engineers wanted
to achieve three goals:
- Easy to use
- Excellent sound quality
- Modern and advanced design
This transformer unit is designed to work in combination with the AUDAC Q2 or Q4 for the
Q2TR respectively Q4TR. The unit transforms the 4Ω output of your AUDAC Q2 or Q4
amplifier to a 50V, 70V or 100V output level for use in a system with high impedance speakers.
This transformer unit gives you the possibility to attach four mono zones or two stereo zones.
