PB26 Reporter audio distribution box

         As audio technology continues to improve, so the requirements for  distributors  continue to increase. In order to improve the safety and stability of the  audio system, PLA independently develops and produces distribution  amplifiers with performance indicators that enable more stable and clear  transmission of the input signal. Audio distributor in addition to impedance  matching, there is audio gain, so that the audio signal can be sent to  multiple output devices at the same time a short distance without being  affected, so as to ensure the synchronization of audio transmission to a  certain extent. Audio distributor can be used in theaters, theaters,  multimedia conference rooms exhibition halls, audio and video systems  conference rooms and other occasions supporting products. PB26 reporter audio distributor, with AIT (Audio Isolation Technology) audio  isolation patented technology, the internal selection of Switzerland  imported NEUTRIK connector jacks, Audio Press Box has 2-way  microphones / line XLR input,5-way XLR output ,  stereo / mono switch, can be used as dual 1-way XLR input, 5-way XLR  output and 4-way 3.5mm output, stereo / mono switch, can be  used as dual 1-way XLR input, 10-way XLR output and 4-way 3.5mm output. The Audio Press Box features two microphones/line XLR inputs, ten  XLR outputs and four 3.5mm outputs, with stereo/mono switching for dual  1 in 5+2 or single 1 in 10+4 distribution, and ten XLR outputs with separate  ground/ground switches. Another with -20dB signal attenuation switch,  easy to adapt to different signal levels.
