Following the installation of the technical infrastructure in their newly constructed office building in Bor, Hongda LianShao Mining sought to enhance their conference rooms, designed to accommodate up to 20 participants. The requirement was for equipment that would guarantee razor-sharp video and crystal-clear audio for video calls with the company's headquarters in China. This equipment was also expected to double as presentation tools during internal meetings and training sessions among employees, thus underlining the need for versatility and high performance.


Given the size of the room and the substantial amount of daylight it receives, we opted for the Sony VPL-PHZ60 laser projector, known for its exceptional light output of 6,000 lumens. Its compact size (422x129x338 mm) and lightweight build (around 7 kg) make it the smallest projector available in the market that offers this level of brightness. The device's light source boasts a remarkable lifespan of at least 20,000 hours. This makes the Sony VPL-PHZ60 a long-lasting, premium-quality solution that eliminates the need for bulb replacements, thereby reducing additional maintenance costs.


Complementing the system, we've also included a motorized projection screen, which can be conveniently operated using a remote control. Additionally, we've equipped the setup with an appropriate camera to ensure high-quality video capture for remote conferencing and presentations.

The setup features the Infobit VB40 ePTZ conference camera, boasting a 4K Ultra HD image sensor that suits both small and medium-sized meeting rooms. The system also includes omnidirectional wireless microphones equipped with noise-cancellation functions. These ensure uniform and clear audio output, independent of surrounding noise levels. The microphones' battery life is impressive, offering up to 8 hours of continuous use and a standby time of up to 6 months. Thanks to the included charging pads, keeping the microphones powered up is both quick and convenient.


The system also features a 4K Ultra HD soundbar paired with a wireless subwoofer, delivering clear, amplified sound during meetings and presentations, ensuring an equal distribution of audio throughout the room.


Recognizing the potential of the atrium setting within the Hongda LianShao Mining business complex for hosting outdoor events, the management chose to invest in appropriate portable sound systems. We provided RCF touring TT25-A MKII active speakers paired with an RCF F 12XR channel mixing console, as well as Audix AP62 OM5 wireless microphones with stands.


To guarantee easy transportation, the entire system - including the wireless microphones, audio mixer, and a drawer for cables and handheld microphones - is housed within a touring rack case. This comprehensive setup ensures superior sound quality and versatility for any event, whether indoors or outdoors.


Through the acquisition of cutting-edge video-conferencing technology and portable sound systems, Hongda LianShao Mining is poised to facilitate rapid and efficient communication among employees, thereby enhancing the quality of their business processes. This strategic investment will undoubtedly contribute to the improvement of the company's overall business performance and success.
