The AMCM Series Agile Micro Channel Modulator from Blonder Tongue is a module that installs in the MIRC-4D or MIRC-12D rack chassis, not included. It forms part of an RF modulation system for analog CATV applications, and supports an output frequency range of 54 to 860MHz.
- Audio Auto Gain Control (AGC)
-
- Prohibits commercials that accompany broadcast programs from having modulation levels substantially higher than the broadcast program; and having an average maximum loudness substantially higher than that of the broadcast program
- Provides consistent audio levels among all broadcast programs on different channels and among different programs within the same channel
- Modular design allows for deployment of 12 channels in a single 2RU rackmount chassis
- Utilizes SAW filters for improved performance
- Die-cast chassis for RFI immunity

Good Solid Mount
Got for my 2019 TRD Off Road. Works great, solid mount. Phone easy in, easy out once you get used to it. Looks and feels well made.

Solid Product
I was a bit skeptical based on the price ($85 total after taxes) but you can tell that for the price, this thing is sturdy and high quality. Holds solid onto the vent and keeps my iPhone in place. Easy to adjust and move to your liking, also easy to turn 90* and have your phone sideways. Only drawback is that is obstructs the view of the clock on my 4Runner and slightly obstructs my windshield, but I am sure I will get used to it.

Great phone holder
I use this phone mount in my Subaru Impreza, and it works perfectly with my vents. It holds my phone super securely—no wobbling or slipping—so it’s great for navigation or hands-free use. Really solid and reliable for the price.

Excellent product.
First impression: excellent product.
The only reason I deducted a star is because the price is obviously quite insane.

A+ mount for 4Runners
This is the best phone mount I've ever had. Got it for my 2021 4Runner. Very strong, doesn't come loose, easy to place and remove the phone from the mount. Can't recommend enough.
