The CATV Channelized Audio/Video Modulator, Channel 41, from Blonder Tongue is an all-solid-state audio/video modulator that provides a modulated visual and aural RF carrier output on one specific CATV channel. The unit modulates the audio and video inputs and provides the requested RF CATV channel output for use in a CATV, MATV or SMATV system. The modulator accepts standard (sync negative) polarity video at a 0.7-2.5V peak to peak level from sources such as a TV camera, video tape recorder, TV demodulator or satellite receiver.

The modulator features a +55dBmV RF output level, and an IF SAW filtering for adjacent channel operation. All aeronautical channels are offset positive with a tolerance of ±5kHz as required by FCC 21006. All level controls are located on the front panel. The RF level control provides up to +55dBmV output. The video modulator control sets the depth of modulation for 87.5% over an input video level range from 0.7VP/p to 2.5VP/p. An audio modulation control permits adjustment for ±25kHz peak deviation of the aural carrier.

Q: 1. i want to terminate 21 tv rg6u cables to two splitters in my residence will a cable tronics cta-35 /1000 pr amphlifer help ?

A: No, the CableTronix CTA-35/1000PR CATV Distribution Amplifier will not work for your needs. Based on your request you will need the CableTronix CT-BDA24 for this installation. CableTronix CT-BDA24 1 GHz Single Input/Output Multimedia Drop Amplifier with Adjustable Gain Control and Switchable FM Trap BH #CACTBDA24

Q: 2. Can this switcher stream directly to the internet like the Blackmagic Mini?

A: The AVmatrix Micro 4-Channel HDMI & DP Video Switcher features an USB-C Out for Capture & Streaming, which could be used to directly connect it to a computer, for live streaming purposes over the internet.

Q: 3. Does this device require power if used for POE cameras?

A: This will not transmit any POE. This is meant to convert a COAX signal and allow you to transmit the signal over Cat5.

Q: 4. Will the USB-C output be recognized by Zoom for both video and audio?

A: Yes, with the USB-C output connecting to your computer, Zoom should be able to recognize the device as a video and audio capture.

Q: 5. which norm handles? pal-B/G pal-N or NTSC? thanks.

A: The Blonder Tongue CATV Channelized Audio/Video Modulator with SAW Filtering SAW is NTSC only.

Q: 6. This basically looks like the Elvid video switcher, what is the difference between this and the Elvid?

A: No differences between the switchers, other than the branding.

Q: 7. Are the inputs a mic or line? Can a microphone cable be plugged into this unit and be heard from the speakers? Thanks.

A: The Wohler VMQ4 4 Channel Audio Monitor is expecting a line level signal into its Phoenix input connections and would not power a microphone directly.

Q: 8. does it have 2 seperate audio programe monitoring?

A: You get simultaneous monitoring of up to four audio sources on four analog inputs with voice quality fidelity.

Q: 9. How long the mini cable?

A: The included mini cable is 1.5 meters in length. (Just under 5 ft.)

Q: 10. Can the inputs scale down 4k video input to 1080p? the intended camera for use is the BHG1 which outputs only 4k over HDMI?

A: No it can not. You will need to send a 1080p or lower signal for the switcher to process the video. Keep in mind that on cameras like the BGH1 your recording resolution and output resolution do not need to be the same. Therefore it is possible to record in 4K while outputting a 1080p video signal if necessary.
