The Blonder Tongue CATV Modulator with SAW Filtering Channel 73from Blonder Tongue CATV Modulator with SAW Filtering Channel 73is 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. Am I understanding this correctly--the PreSonus Studio Channel has a compressor, but does NOT have a Noise Gate? Meaning that noise gets increased in volume as well? Thanks.

A: Correct, there is no noise gate or expander in the Studio Channel. Compressors don't increase level (or noise), they only decrease or limit dynamic range. If you don't have your input gain set correctly, that will decrease your signal-to-noise ratio. If you apply compression to a noisy signal, that noise will seem louder because you've brought the input signal peak and noise floor closer together by compressing the dynamic range of that original signal. Hope that helps!

Q: 2. Does this include the power cord to the mixer?

A: The Shure SCM268 utilizes a 3 pin IEC power connection with power cord included.

Q: 3. What is actual weight of this case?

[22 x 6 x 4"] needed it for old system works like new when changed. 5

[CATV channel 73] Worked perfectly. 5

[22 x 6 x 4"] I've been selling and installing both the RF only and RF+IP models of the ZVPRO since 2015. We had one power supply fail in that time frame. That unit was in a less than ideal location being bombarded with construction dust. The customer also had daisy chained power strips which I'm sure didn't help. That's it. We've had no other issues. All these units are still in service. 5

[CATV channel 73] 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. 5
