The Blonder Tongue CATV Modulator SAW Filter Channel 38from Blonder Tongue CATV Modulator SAW Filter Channel 38is 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.

Related Questions and Answers

Q: 1. What is the difference between Atlas and Victor carts?

A: The Proaim Atlas V2 Video Production Cart (38"), BH #PRATLSV238, features a heavier payload capacity in a smaller form factor than the Proaim Victor V1.1 Video Production Camera Cart (42"), BH #PRVCTRV142. The Atlas V2 also offers larger, rotating,(2), smooth and quiet 10" pneumatic wheels.

Q: 2. Can residential input coaxial cables (TV, weather station, etc) convert directly to RJ45/RJ11 connector for indoor weather station console? VideoEase CATV Balun II appears to do this. Thank you...

A: Yes, you are able to use your standard coax cable and convert the signal to RJ-45.

Q: 3. How many stops of diffusion on the translucent surface?

A: It is not specified but most 5-1 are about 1 stop diffusion.

Q: 4. Does this have a crossbar? The photo shows a crossbar and the overview mentions it, but not "in the box" items.

A: The Proaim Atlas V2 Video Production Cart (48") BH #PRATLSV248 includes the necessary crossbars as described.

Q: 5. Is this one or two stands?

A: This is 1 stand.

Q: 6. Does this come with a tripod?

A: A tripod is not included. Besides supporting add-ons, the Atlas V2 also offers threaded holes at multiple locations for attaching accessories. These consist of 1/4"-20, 3/8"-16, and ARRI-standard anti-twist 3/8"-16 threads.

Q: 7. is it a Macintosh compatible monitor?

A: Yes, the Dell UltraSharp 38" 1600p Curved Monitor is compatible with MacOS.

Q: 8. Does clamp include 1/4"-20 screw?

A: There is no 1/4"-20 screw included.

Q: 9. Will this clamp accept a Sirui TY-70 plate? The Sirui plates are wider than standard

A: Yes, the Sirui TY-70 plate can fit the DAC-38.

Q: 10. Is it possible to mount/suspend this arm from above?

A: The MBA38 is not intended to suspend from above. It does come with two types of mounts -- a clamp style mount and permanent flange mount. The stem for the arm inserts into the mount from the top. You could attach the clamp mount to a shelf and then position the arm so the mic comes downward, but the arm can not be mounted upside down.

[CATV channel 38] Worked perfectly. 5

[CATV channel 38] I have Denon & Atmos speaker setup, cablebox from Comcast & a subwoofer. The cheap $20 isolator available online didn't do a good job since comcast signal was degraded per their tech. He said that it introduced some noise feed back to their other customers. Not sure how much of that is true but he did say that if I were to get an isolator get something over 1000mhz and this one fit the spec. I installed it and so far all is great. No issues with performance but the box label instructed to read instruction which were not in the box. So I went to their website and read it. 5

[CATV channel 38] I was getting hum from my REL T9 subwoofer. REL customer service helped me track down the cause to electrical noise originating from my coax Xfinity cable connection and flowing through my cable box and my AV receiver and out to my subwoofer. After adding this ground isolator the hum immediately disappeared. 5
