Video conferencing (VC) continues to enjoy unprecedented growth levels since the pandemic, and Biamp now wants a piece of the action. It makes its play for the small to medium-sized meeting room market with the imposing Parlé VBC 2500.
Measuring nearly one metre in length, this all-in-one conferencing bar takes a lot of the technology Biamp has developed over its 46 years in the professional audio-visual (AV) space and hands it to SMBs. Whereas most competing VC bars offer a beam-forming array made up of five or six microphones, the VBC 2500 boasts a highly accurate beam-tracking array comprising 27 microphone elements.
It sports a 4K UHD camera capable of delivering up to a 2160p resolution at 30fps and teams this with a wide 120° field of view (FoV) plus digital pan, tilt, zoom (PTZ) functions with 5x zoom capabilities. The camera incorporates a mechanical shutter that automatically obscures the view when a meeting has finished or a user disables video from their UC app.
Sound output is a cut above the rest, too, as Biamp has designed the speaker array to accurately reproduce human speech. The array comprises a pair of 20W speakers in sealed enclosures plus passive radiators to improve bass, and it uses active distortion compensation to ensure a flat response.
Placement options are plentiful: the VBC 2500 has an integral hinged desk stand and the kit includes a metal wall-mount bracket. Behind the rear removable panel is an external power supply socket plus a USB-C host connection port – for BYOD operations you can connect the VBC 2500 to Biamp’s optional Devio SCR-10 desktop unit.
A standout feature is Biamp’s automated room configuration: simply plug the bar in, press the Launch button underneath and stand back. The bar measures the room’s acoustics by emitting a series of sounds that wouldn’t be out of place in a 1950s sci-fi movie.
It uses the audio feedback to optimize the mic array, speakers and integral digital sound processor (DSP) specifically to its environment. The upshot is that anyone can set up the VBC 2500, and the same process is used if it’s moved to another room.
Installation took seconds. We plugged the VBC 2500 into a USB port on a Windows 10 Pro host and all necessary drivers were automatically loaded. As to which VC software platform to use, the choice is yours – the VBC 2500 is UVC (USB video class) compliant and we had no problems using it with Skype, Microsoft Teams and Zoom.
Video settings can be tweaked to suit using Biamp’s free Camera Controller app. Auto-framing and backlight compensation can be disabled, PTZ functions manually operated, the image mirrored or flipped, UC profiles for Microsoft Teams, Google Meet and Zoom applied and three presets saved for further use.
Video quality at 1080p is impressive, and we found the image was sharp and clear with great contrast and color balance. Backlight compensation works well, as does auto-framing, with the camera snapping to the active speaker in a couple of seconds and tracking them if they moved around the meeting room.
Audio quality is even better – this is easily the best-sounding VC bar we’ve yet tested. Biamp’s speaker technology delivers a superb sound, with a warm, deep bass, natural-sounding voices and none of the shrillness you’ll find with smaller VC bars.
It’s loud, too, as we had to drop volume levels to 40% for our 24 square meter meeting room. Crank it up to maximum and it’ll go with you as the sound doesn’t break up at all.
The Parlé VBC 2500 isn’t as versatile as Logitech’s Rally Bar, which offers BYOD and standalone modes courtesy of its Android OS, but Biamp can’t be beaten for presentation quality. Video and audio are exceptionally good, digital auto-framing is fast and the smart launch mode makes meeting room setup a piece of cake.
