Class-D loop amplifier Pro Loop D15
The Pro Loop D15 amplifier is primarily designed for use in public and commercial facilities. The system integrates active protection against short circuits and proves itself through high reliability and operational safety.
The Pro Loop D15 provides induction loops with highly stable inductive audio signals of exemplary quality.
The Combo XLR-3 input as well as another input via Phoenix contact can be individually configured:
a) as audio-in (symmetric)
b) as microphone-in (asymmetric)
The microphone mode also allows the activation of phantom power for condenser microphones.
The Automatic Gain Control (AGC) ensures a constant field strength, provides high stability of the sound volume and good sound reproduction. The monitoring output provides direct connection to other loop amplifiers.
