Loop amplifier Pro Loop D5LOS
The Pro Loop D5LOS amplifier offers an ideal solution for use in function rooms and larger assembly spaces. High operating comfort and corresponding power reserves create the flexibility to adapt the loop system to a wide range of spatial conditions.
The combo XLR-3 socket and the phoenix contact at the INPUT 1 and 2 inputs can be configured as LINE input or microphone input (balanced in each case). A phantom power of 12 V can also be activated at the inputs for the use of static microphones. In addition, the amplifier has a 100 V input for connection to appropriate loudspeaker and PA systems. The input gain is adjustable at all three inputs.
The powerful amplifier features Automatic Gain Control (AGC), which ensures stable sound with excellent speech reproduction even under difficult acoustic ambient conditions. To perform acoustic quality checks on the induction loop outputs, the Pro Loop D5LOS has a monitor output for connecting headphones.
