Designed for fixed installation, the Lectrosonics R400A receiver is a half-rack unit featuring Lectrosonics's digital hybrid technology. The dual antennas are an confirmation of its Smart Diversity enhanced reception circuitry. The rear panel features both XLR and 1/4" phone output connections, both with output level control adjust. A comprehensive LCD displays pilot tone, antenna phase, transmitter battery status, audio level, RF level, battery timer, frequency, and transmitter switch settings.

Half-Rack Design    Digital hybrid Technology

Digital Hybrid technology digitizes the audio signal at the transmitter end. The signal is then converted to analog at the receiver end, eliminating analog compandor circuitry. The result is accurate transmission with great range, without noise caused by analog compandors.

SmartTune automatically scans for usable frequencies within the systems frequency block.

Incoming radio frequency level and rate is carefully analyzed in order to determine the optimum timing for phase switching. The result minimizes drop-out and radio frequency interference.

The R400A utilizes microprocessor components, attributing to its small size. The optional RMPR400-1 / RMPR400-2, rack-mount kits enable mounting single or dual units into a 19-inch single rack space.

Related Questions and Answers

Q: 1. Is this receiver compatible with the newer Sony HVL-F60M flash, which has the Mi shoe interface?

A: Yes, it does, but for it to work make sure the transmitter has the latest firmware for Sony

Q: 2. Will this work on my Nikon SB-910 with a Elinchrom EL Skyport Plus HS?

A: It will fire the flash (manual mode only). Remote power-level setting is not available.

Q: 3. Does the work with the new Canon EL-5 Flash with Hotshot?

A: Yes, the receiver will drive anything that has a standard hot shoe. End-users beware that the system is a manual driven unit and no TTL will be provided.

Q: 4. Will Sony flashes (HVL-F43AM via Adapter ADP-AMA, or HVL-F43M without adapter for example) work with Nissin Air R and Air Commander?

A: I don't know. I bought the Nissin for my Nikon system and could never get them to work so I sent them back. Look at Phottix or Godox (sold under many names) for my wireless trigge/commander for a better system. I ended up getting both and love them.

Q: 5. Will this work with Godox, Profoto, and other studio strobes? I've been waiting for Nissin to make an equivalent strobe like the Profoto B2 for more power than their current offering. So will this trigger studio strobes with TTL and most importantly HSS?

A: No it will not trigger your strobes with TTL or HSS. The Air R receiver is primarily made to work with Sony MIS flashes. In this case, it will support TTL and HSS with those flashes. The Air R receiver does have a PC out so you can trigger a studio strobe but that is all. You would have no control what so ever of the studio strobe.

Q: 6. I bought the Nissin Air commander kit (A. Comm. with the matched i700A flash. I have an older Nissin Di622 Mark II flash. Will this Air Receiver work with it? (The Di622) I'm shooting a Nikon system. Thanks!

A: I shoot Canon and it works perfectly for there flashes on a Sony system. I am positive they would work for Nikon flashes. The older flash I can not say because they are system dependent.

Q: 7. Is this dongle compatible with the MK710, K800and K520 keyboard?

A: Yes, you can use the Unifying receiver for all three of these devices. You'll need to download the Unifying Software in order to pair them all to the single receiver. Here's a link to the download: https://support.logi.com/hc/en-us/articles/360025297913. Hope this helped and that all is going well. - Richard from Logitech

Q: 8. Is this receiver compatible with the Yongnuo 600rt flash (canon compatible) allowing me to use the x100f Fuji camera and trigger the Yongnuo with TTL capability? Thanks!

A: If this receiver is Canon compatible it will work with any Canon shoe flash.

Q: 9. How does this attach to a light stand? Do I need a special attachment?

A: The Elinchrom EL-Skyport Receiver Plus has a 1/4 -20 female tripod socket on the bottom of the hot shoe on the receiver. If your light stand has a male 1/4 -20 screw on the top of the stud on the light stand, then it should work for your usage needs. If not, I would recommend the Impact Deluxe Umbrella Mount with Adjustable Shoe, B&H # IMDUBAS, for your usage needs. This would give you the advantage to be able to tilt the receiver (and any flash mounted on the receiver) up and down, and has both a hot shoe and a 1/4 -20 male thread as attachment options for the Elinchrom receiver.

Q: 10. Will this give TTL on mirrorless as well?

A: Yes
