Loop amplifier Pro Loop D5 LOS
The Pro Loop D5 LOS 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-port and the Phoenix contact at INPUT 1 and 2 can be configured as LINE-IN or microphone-In (balanced) konfiguriert werden. 12 V phantom power can be activated onn both both ports for the use of condenser microphones. In addition, the amplifier has a 100 V input for the connection to according PA- and audio systems. The input amplification can be adjusted on all 3 inputs.
The powerful amplifier is equipped with Automatic Gain Control (AGC), which will provide constant sound and clear voice intelligibility even under difficult surroundings. The sound quality of the Master and Slave loop can be checked via a monitoring port for headphones.
