Induction loop amplifier up to 1000m²


• The PROLOOP DCCplus is designed for areas of up to 1000m². It is the ideal solution for event rooms and conference halls.
• The XLR jack on input 1 is fixed as a microphone input (balanced, sensitivity: 1 mV) configured. The XLR jack on input 2 can be configured as LINE input or microphone input (symmetrically).
• When using the microphone mode, a phantom current of 15V can be activated for static microphones. Also, an additional gain can be enabled on these 2 inputs. Amplification for both inputs can be adjusted separately by front panel potentiometer.

• The output amplification is generous (up to 12A RMS) and guarantees good audio transmission by the system.
• The Automatic Gain Control makes sure of a consistent field strength, offers more stability of volume and excellent audio reproduction.
• The supplied 6.3mm jacks Slave In and Slave Out can be equipped with two PROLOOP DCCplus to establish a Low-Overspill loop system.
• Adjuster for reducing field strenght loss to metal in the surroundings.
