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

Q: 1. can I steam to facebook ?

A: With the AVMATRIX PVS0615U Portable 6-Channel Switcher with USB Streaming & 15.6" Display, yes, you can stream to Facebook.

Q: 2. This unit accepts SDI audio in, but nowhere does it indicate that audio can be output via SDI programs out?

A: Regarding the audio carried on the SDI, it will follow the entire pathway using the AVMATRIX PVS0615 Portable 6-Channel Video Switcher with 15.6" LCD Monitor. If the SDI channel carries an audio signal from the source, it will also output the same signal with embedded audio.

Q: 3. How do you use this lens with graduated filters?

A: I used it without any additional filters.. it fit well with the Blackmagic pocket cinema camera.I suppose one can get micro 4-3 adapters and some converters to hook up your filter.I liked the lens.. the balck magic camera still was not fully integrated ( a few controls did not work).when you shut off the power the lens did not retract fully.... This is not the lens problem but the camera problem.

Q: 4. Can this unit do its own scaling? Example, having a camera at 1080p29.97 and one at 59.97... Frusterated that Blackmagic inputs all have to be the same to show up when we have PCs feeding into it and have to have a scaler for each of those feeds.

A: Yes. The unit auto detects input format and uses it and one can select output format, which will apply to all signals processed and mixed via this switcher.

Q: 5. Are both the battery level for the camera and battery grip displayed in the camera information? display

A: No, when using a battery in the Olympus HLD-9 Power Battery Grip and in the camera, the camera will only show the battery level for the one it is currently drawing power from. It will not show battery level for both batteries simultaneously.

Q: 6. Can three separate cameras have there own background image for multi cam green screen?

A: That is not possible with this switcher. You would not be able to have 3 separate camera and green screens set up.

Q: 7. My audio and video are out of sync. Is there a fix?

A: Yes there is an audio delay function built into the switcher. This will allow you to adjust the timing of the audio to match your video. please check page 22 of the manual for more information.

Q: 8. Will the HLD-9 work with the new OM1 Camera?

A: Olympus HLD-9 Power Battery Grip BH #OLHLD9 will not work with the OM SYSTEM OM-1 Mirrorless Camera BH #OMOM1. OM SYSTEM HLD-10 Power Battery Holder BH #OMHLD10 will work with the OM SYSTEM OM-1 Mirrorless Camera BH #OMOM1.

Q: 9. Can the bmdp4k zoom this lens ? (not using the lens switch)

A: The lens can be used with a digital camera compatible with the lens mount standard for the“Micro Four Thirds System.

Q: 10. Will it work with the E-M1 Mark iii?

A: YES, see page 24 of E-M1 Mark III manual https://learnandsupport.getolympus.com/sites/default/files/media/files/2020/02/E-M1Mk3_ENU_00.pdf
