Bogen Communications X450 overview

  • 1Description

The Bogen Communications X450 is a Black Max Series rackmount 70V power amplifier offering powerful, full-range amplification for constant-voltage systems in restaurants, retail stores, offices, and more. Its efficient Class-H amp design delivers 450W to each of the two channels while maintaining low noise and distortion. Per-channel volume control, input sensitivity selection, and 60 Hz low-cut filters allow easy optimization of levels and tone. The 3-pin pluggable terminal strip inputs are electronically balanced, while the 5-pin barrier strip output is transformerless.

Independent variable-speed fans keep the X450 cool even when mounting does not allow for open space above or below the amplifier. Built-in voltage stabilization and multiple protection circuits ensure reliable operation hour after hour. The auto-sleep feature makes this amp ideal for continuously powered systems. Integrated power sequencing for controlling multiple Black Max amps in large systems helps prevent in-rush problems. These features are packed into a heavy-duty steel chassis that occupies just two rack spaces.

450W per channel at 70V with independent low-cut filters on each input
Low noise and distortion with high slew rate
Highly efficient Class-H amplification driven by a conservatively rated toroidal power transformer
Transformerless direct drive outputs
Electronically balanced high-impedance inputs
Large output heat sinks and dual independently controlled, high-output, variable-speed cooling fans provide reliable cooling and quiet operation while reducing dust accumulation
Internal electronic components are located outside of the forced air stream flow to ensure minimal required maintenance and cleaning
Front-mounted fan filters are easily removed for cleaning
Multiple electronic protections including overcurrent, DC voltage, and thermal circuits
Clip/limiting circuit continuously monitors the amount of distortion in the output signal and reduces input levels as the amplifier approaches clipping
Back-Slope AC voltage stabilization regulates the AC energy supplied from the power toroid to improve system performance and reliability despite varying AC supply conditions
Defeatable energy-conserving sleep mode with instant-on return signal operation reduces wasted heat production in paging systems with intermittent use
Pluggable terminal strip for sequencing wiring in multi-amp installations
Sequential turn-on feature minimizes in-rush current from the AC power mains when multiple Black Max amplifiers are daisy-chained together for sequential turn-on; the first amplifier in the series will control the powering up of the other amplifiers with approximately one second of delay between units
Directly stackable, mounts in two rack spaces without need for extra space above or below

    Bogen Communications X450 reviews

    X450 Black Max Rackmount 70V Power Amplifier (450W per Channel) is rated 5.0 out of 5 by 1.
    Rated 5 out of 5 by from Love this product..excellent performance This was an easy to install Dual channel amp. It packed everything I needed to turn a horrible old system into a quality sounding set up that one would be proud of.Of course I had to swap out several components and put in a sweet Gator rack. All in all this amp was indeed the backbone of the system but it has proven itself more than worthy.I built a shrine around it and all the listeners come and bow down to it.
