The BGW VXi 6.3 Multi-Channel Power Amplifier.
Designed for Home Cinema installations, the BGW VXi provides an impressive 800W into 8 ohms of analog power for the Left, Centre, Right (LCR) speakers providing enough headroom to satisfy any Home Cinema LCR requirement.
The remaining 6 channels provides an equally impressive 400W into 8 ohms. These channels can be used for surrounds or atmos speakers.
The BGW VXi 6.3 can be used for loudspeaker systems requiring a 3-way, active set up, for example, the Krix MX-40, Theatrix or Cinematix. Combine this system with a good Class-D amplifier for the Sub-Woofers, and you have a world class LCR+S active speaker set up that is sure to impress.
The BGW VXi 6.3 is not the sexiest looking amplifier but it does include some very good signal limiting, clip detection, over-current and thermal protection. For those concerned about the looks of the BGW's, ask yourself, "Are you watching the amplifier or are you watching the screen? 🙂"
With over 30 years of cinema sound installations, BGW delivers an impressive audio experience.
Overview
Signal to noise ratio approaches a staggering 124 dB. Silence never sounded better!
Each amplifier is built to withstand the rigors of commercial cinema life.
Multiple temperature sensors control a variable-speed cooling fan to assure stable long term operation.
A new clip-detector and limiter circuit make it impossible to overdrive these amps.
