The Audio-Technica 1800 Series provides a professional, dual wireless portable solution, while addressing the issues of portability, function and cost.

The 1800 Series wireless microphone system delivers the flexibility of a dual wireless system in a single compact and rugged, camera-mounted receiver. This system includes the ATW-R1820 dual receiver and 2 ATW-T1801 bodypack transmitters. Other configurations are also available.

The ATW-R1820 dual receiver is designed with 2 internal, True Diversity UHF receivers with an internal Antenna/Splitter amplifier. Dual balanced outputs enable incoming signal to be mixed, or independently assigned to each output. Independent audio level controls provide flexible audio mixing and monitoring possibilities. The compact ATW-R1820 is powered with six AA batteries, one of the internal receivers may be turned off to preserve battery life.

The ATW-T1801 bodypack transmitters are compact and rugged with 4-pin HRS connectors. The input is switchable between mic and line signal. Selectable Hi/Lo RF output power enhances range when needed and a 2 color power/mute LED indicates transmitter status. The transmitter is powered with 2 AA batteries for up to 9 hours.

Additional features of the 1800 series include 996 Auto-Scanning frequencies, simultaneous operation of up to 10 systems, back-lit LCD, soft-touch buttons and metal components.

      I have more than 40 years as a film and video DP so I know a little bit about good audio, and I have used and trusted AT mics on everything from broadcast interviews, sports and documentaries, to feature films. We tested this unit against other brands costing as much as $1000 more, and the ATW-1821 was the clear winner every time. Anyone who says they get noise out of this mic simply doesn't know how to use it properly. If you want a good, dependable wireless system, with fantastic sound quality, then you need to buy the ATW-1821.

      I tested this with another professional sound mixer in LosAngeles, and while we were both impressed with the price wewere underwhelmed with the performance. Range and noisefloor were our main issues. While it is probably fine forreally low budget reality stuff, weddings etc, I could notstop obsessing on the noise floor. Also the noise wouldpump up a little bit while transmitting/receiving. Withsome tweaking of output levels etc we got it running prettyquiet but by then I could not stop obsessing about the noise.Keep in mind I am used to using a Zaxcom or Lectrosonic 411as a camera hop, so I am comparing it to systems that costwell over twice what this one does and have more powerfultransmitters. But my final opinion would be that they gotclose but I wouldn't trust it for broadcast/film work wherethe sound quality would be scrutinized by post.

      Expertise: Professional sound mixer for television/film

      Problems Encountered: Noise floor was too much, also increased audibly whiletransmitting/receiving. Underpowered transmitters, receiverseemed well built but transmitters were too plastic.

      Previous Equivalent Item Owned: Zaxcom Stereo link

      Items I Recommend: XLR cables, lots of AA rechargables.

        I use these mics to capture sound directly into my GH4. I turn them on, they're tuned in and work great. From one end of the building to the other, through walls, never any interference. Sound has been crisp and clear.

          I admit to only using this mic set for a small amount of time to date, but from the time I have had it, it has worked as hoped. Nice clear sound and from a good distance away. I've had no trouble hearing around walls and through various rooms when testing it as well.

              Comments about Audio-Technica ATW-1821 Dual Wireless Microphone System:

              I'm using these mics as my primary audio source for interviews on the documentary I'm shooting, and also to capture the conversation of the subject while he's at work.

              When it worked, it worked splendidly. The frequency search feature helped me in a situation with a lot of RF. However, the receiver quit working on me and I'm not certain why. The A-T support was nearly nonexistent, by the way. I had to spend a lot of time searching for a way to contact them, and they spent the entire conversation asking me questions like "did you try new batteries?" "were the batteries put in the right way?" "are you sure they were fresh batteries?" "are you REALLY certain you put them in the right way?"
              So...not helpful.
              Speaking of batteries: The unit requires six AA batteries to run, and while its battery usage is good (I got about 3 hours of use using just one channel, and 2 hours using both mics), replacing the batteries is a pain. They are put in a double layer, and there is one battery that sits in a deep corner under the nubs A-T uses to hold the battery cover in place that is next to impossible to remove. A-T should add one of those ribbons to tug to pop it out.

                  This is my second ATW-1821 Dual Wireless system kit. It has provided me with many different recording options and can facilitate up to 2 wireless signals at once per receiver. The only reason I didn't give it a 5-star is because the cube on my first kit failed after 2 years of use (granted it was road use and took its share of abuse).

                    The Audio-Technica ATW-1821 dual wireless system saved the day recently at a wedding I was videoing. In the past I relied on a sound feed from the church's sound system and got what they had to offer, which was not always the best quality. I invested in the ATW-1821 to become independent of sound systems and my investment paid off in big dividends. The sound is clear, smooth and very reliable. No drop outs even at the distance I had to throw between the transmitters and the receiver. I'm thinking about buying a second system. So far, no negatives.

                        I use this for audio for video with my videography business. It works very well, but when you are using both inputs on the receiver the batteries on the receiver only last me about 4 hours. Great features include: dual antennas, one receiver can handle 2 sources, headphone output on the receiver (nice for DSLRs which don't have a headphone output), frequencies are very configurable, you can choose to keep the 2 sources on separate tracks or mix them together - effectively opening up and additional input on your cam so you record 3 sources if you have 2 XLR inputs, body pack transmitters are light and work well.

                          I've used these for recording documentary interviews. The controls and general feel are quite good. I was very disappointed with the background noise level, about 12dB higher than the noise level on a far less expensive wired lavalier. I understand that electronic noise is an issue with wireless units, but for the price of these items I would have expected better.

                            I purchased this system to replace one that gave us nothing but problems. It was an excellent investment. This wireless system has saved us from trouble many a time, even when ambient conditions would have adversely affected the sound. We are very pleased with it, and would definitely recommend it as a top choice. The kit we purchased came with a hand-held microphone as well, which was also very good. We were able to use it for clean interviews in very noisy environments.

                            Like the other reviewers I can't get over the modulation noise that I assume stems from the unit's compander. It's not as noticeable using the inexpensive supplied mic, but after adding a Tram TR-50 it really stands out. Very disappointing.

                            I have more than 40 years as a film and video DP so I know a little bit about good audio, and I have used and trusted AT mics on everything from broadcast interviews, sports and documentaries, to feature films. We tested this unit against other brands costing as much as $1000 more, and the ATW-1821 was the clear winner every time. Anyone who says they get noise out of this mic simply doesn't know how to use it properly. If you want a good, dependable wireless system, with fantastic sound quality, then you need to buy the ATW-1821.

                              coverage to indie film.

                              Good, solid reliable equipment with great sound.

                              I work in the DC area so interference can be a serious problem. Frequency agility has solves any issues on that score.

                              A/T is one of my favorite brands because they give
                              good value for the money. I've found Audio Technica to be a good choice for those of us without an unlimited budget.

                                I completely second everything Dan said about this wireless set.

                                I bought one of the dual channel sets for myself after researching up on it and thought it would be perfect for what I was looking for, but after using it a bit on some projects I could not stand the self noise (the "companders" working?) that these have when being used.
                                What's worse is that the noise keeps changing/pumping in and out with the dialog and audio going through the TX/RX(wouldn't be near as bad if were a consistent noise, but it's not and pretty noticeable).

                                I currently have mine in for repair being checked for defects, but from what I have read and been told so far, this is just the way these wireless are(would be ok for wedding and low budget stuff, but definitly not for high quality indoor-low background noise to cover up TX noise stuff)...

                                  I have over 20 years of professional video experience as a DP and a producer of TV, documentary and corporate video. This Audio Technica package is a Godsend. I like the quality of the construction - and absolutely love the functionality of the ENG dual receiver. Most of all, though, I was impressed with the incredible tonal quality of the sound that we recorded. We had no problems with noise. Our range was not tested at an extreme level since we have been shooting run and gun plus interviews. This is by far the best system I have owned - especially for the money.
