"After many hours of researching for a device to meet our needs, I landed on the Barix’s site. Although it is far expensive for our purpose, we had no choice since we needed a standalone device that can stream audio directly from an amplifier output without having a computer in between. I haven't received a phone call or heard from any of our members stating that audio is not working. I highly recommend this Barix Instreamer if your setup cannot have a dedicated computer in between for audio streaming."
"Its simply the best audio encoder for sending audio to Shoutcast V1 and V2 servers as well as Icecast."
"Worked like a charm."
"Also make sure you have a static IP or you will be changing periodically."
"I bought the Barix for freeing up the PC which normally does our streaming."
"This device is wonderful and makes our audio feed sound great."
"I had 2 of these, and both broke their power cable connectors clean off within 5 or 15 minutes of gentle use."
The response frequency: 0-20KHz Output AB two -phase quadrature output rectangular pulse ,the circuit output is NPN open collector output type ,the output of this type can and with additonal added pull-up resistor(not included) is directly connected MCU or PLC ,such as 51 single or Mitsubishi PLC (PLC input mode should be connected to 0V switch function ). Note: If the encoder is not connected to the device can not be directly oscilloscope oscilloscope ( open collector output without pull-up resistor when there is no voltage output ) If you want the oscilloscope in AB two-phase output with two pull-up resistors(not included). Fits for measuring the rotational speed of the object , angle, acceleration, and length measurement.

"I suggest that the description's Output section be updated to be more clear that this unit requires the addition of pull-up resistors to each of the signal wires (white and green)."
"Nice solidly-built encoder."
"It's probably not useful for fine angle detection such as a dividing head as the stiction will magnify issues with backlash if not directly driven."
"I've got this working on both an Arduino UNO and a NodeMCU (ESP8266)."
"I was going to use this with my Raspberry Pi 3 but to get the resolution this encoder can pump out I opted for my Parallax Propeller."
"Cheap and effective!"
"Works as advertised, so far has held up in a bumpy environment."
Connection: Yellow = A phase, Blue = B phase, Red =Vcc power +, Black = power -. Notice: AB 2phase output must not be directly connected with VCC, otherwise, will burn the output triode. Suitable for a variety of intelligent control of automatic guillotine paper machine, civilian measured height human scale, students racing robots and steel cut length control etc.

"These have smooth effortless rotation, are seemingly precise and work as they were intended."
"You have to use pull up resistors or your boards built in pull up resistors (i.e. on an Arduino board use command "digitalWrite(encoderPinA, HIGH)" and "digitalWrite(encoder0PinB, HIGH") in the setup function."

"I had a set of Phillips rabbit ears that worked pretty well until they got bent."
"I was only able to receive a few more channels, but the picture is soooo much better than with the Antenna I had before. I'm still not able to receive CBS/NBC but I'm going to try putting the antenna in the attic and see if it picks up those two."
"We are still keeping cable for just 1 TV, unfortunately we enjoy the History Channel and a very few others, so right now for $80. I put the unit BEHIND our TV and we still pick up channels we enjoy, like ME TV which in our area ATT does not provide."
"According to the instruction manual, I can scan the “Air” channels twice with both the smart amplifier “on” and “off” status."
"I am very pleased with the reception,very clear picture, no static, great variety of channels to choose from and best of all...no monthly fee!"
"One placement works for most receivable channels, reducing antenna moving for better reception for stations with different broadcast tower locations."
"Good Customer Service Saves the Day. I was able to talk to a representative to find out what would be the right antenna for my location and it was determined that the original antenna AT-201B that I purchased wasn't the right antenna for my needs."

Best Electronic Chokes
These ferrite cores work to erase noise that is generated by a portable device or equipment that would otherwise be propagated around them. The ferrite cores come in two split halves, and clamp on to the cable whether it has a connector, or is hard wired to equipment. Make as many loops as you can and/or install multiple ferrite cores until you successfully suppress offending noises.

Now I have ALL the local channels over the air (OTA) and Netflix, Amazon Video, and a bunch of other streaming apps on my smart TV if I want them."
"I picked a heading with the most antennas and then averaged the heading from all of the antennas in that general direction. Now a lot of these channels are terrible, but they're also free, so... All in all I'm very happy with my purchase. I pick up all of the major broadcast networks, a few cool random networks, and some junk channels."
"There are a couple of towers a bit farther out (down in the Akron/Canton area- I'm in Northeast Ohio in Chardon). Before I installed this GE antenna in the attic, I tested it on the main floor of the house. On ground level, in the front room, I pointed it out the window toward the broadcast towers and I could not believe the signal I got! I had to move and adjust the antenna to get signals for other channels, but it demonstrated that it's reception was quite good. I hooked it into my antenna's signal amp (it only gives me a 10 dB bump) and went back downstairs to test. Because I have a long cable run from the antenna to the splitter, I need the signal amp. For its size and lightweight design, I was extremely surprised at how much signal this antenna collects. So, my antenna is pointed at approximately 240 degrees in order to receive broadcasts from Cleveland stations. (My antenna is pointed approximately in that direction - WSW - and I'm receiving broadcasts from Cleveland, Akron, and Canton stations). It'll be interesting to see how the performance of the GE 34792 antenna changes as the weather warms up and the trees fill in. Update 2/18/2015 - Channel 33 out of Youngstown is no longer being consistently received (the signal comes and goes). This certainly can be chalked up to atmospheric conditions because the antenna is not pointed toward that broadcast tower. However, with the antenna pointed toward Cleveland and Akron towers, I'm getting rock solid reception. This explains why I was always adjusting the RCA ANT-751, a more directional antenna whose signal reception was more narrow and focused. In fact, it's more in line (west) with Cleveland towers (where the antenna is pointed) than 17 and 23 (which are farther south). So, it appears the solution to grabbing Channel 49 is to simply upgrade my signal amplifier (due to my long cable run from attic to basement). Still, it's nice to know if the signal amplifier stops working, I don't have to run out and purchase a new one right away. Again, the only Cleveland station not received (signal amp disconnected) is 55 (CW Network). Update 12/10/2015 - A rather large fog blanketed the area last Saturday evening. I realize that atmospheric conditions can come into play and this particular change in the weather had me scratching my head."
"paired along with PCT 1-PORT BI-DIRECTIONAL CABLE TV HDTV AMPLIFIER SIGNAL BOOSTER WITH PASSIVE RETURN PATH to get an extra 15DB i crossed my fingers, ordered and shipped to her aunts place. on 12/27 i went over then and pulled her cable line from the splitter, added 25 feet of coax and ran it into the attic over head."
