Wireless Remote Speaker Microphone for Heavy-Duty Mobility
Cut the cord and maintain mission-critical communications with this rugged, long-range Bluetooth remote speaker microphone.
The Motorola RLN6544A Wireless Remote Speaker Microphone is a commercial-grade, secure Bluetooth audio accessory engineered for elite public safety, military, and commercial radio configurations. Operating completely free of tangled cables, this long-range wireless remote speaker microphone (RSM) establishes an instant encrypted audio pipeline back to its host transceiver over a distance of up to 100 meters. Built with an integrated task light and a large recessed push-to-talk button, the unit enhances personal safety and field workflow efficiency in challenging tactical situations. The Motorola RLN6544A is the updated version of the Motorola RLN6544.
Designed specifically for first responders, municipal utility teams, and heavy industrial dispatch fleets, this wireless microphone solves the common operational bottleneck of restrictive coiled cables when exiting vehicle cabins or navigating equipment racks. It functions via a high-performance Bluetooth link featuring rapid "touch-to-pair" alignment using integrated blue geometric alignment indicators and explicit voice prompts. This specific model is supplied with a high-capacity rechargeable Lithium-Ion battery and a heavy-duty 360-degree rotatable clip, but it does not include a battery charger.
The radio user must ensure that the Bluetooth PTT and wireless pairing functionality is activated within their companion radio's main codeplug software, as this setting is typically turned off by default from the factory. The module incorporates a standard 3.5mm receive-only audio jack for secondary discrete earpieces, alongside a programmable orange emergency button that routes instant priority distress requests back to dispatch centers.

Frequently Asked Questions
Does this wireless microphone include a charging base?
No. The Motorola RLN6544A comes complete with the wireless microphone housing, internal battery, and belt clip, but the dual-unit or vehicular charging dock must be purchased separately.
What is the typical operational wireless range of this device?
This mission-critical microphone features an extended long-range Bluetooth connection that can maintain crystal-clear audio transmission up to 100 meters (328 feet) from the host radio under line-of-sight conditions.
Why does the microphone not transmit when I press the PTT button?
Your connected Motorola radio likely requires the Bluetooth PTT function to be explicitly turned on within its customer programming software (CPS), as this option is often disabled by default from the factory.
Warranty
1-year manufacturer's warranty.

Great light - very bright.
Color: 26Inch Light White
Installed on a Bronco. It wasn't designed for a Bronco, but I was able to mount it after a trip to hardware store and some minor modifications. The quality of the light itself seems good. Time will tell how long it lasts. It definitely lights up the road and is worth the price.

Affordable and bright!
Color: 26Inch Light White, Color: 26Inch Light White
I wish I could've done more of a review, but the videos won't do it justice from my phone. I wanted more takedown light capabilities on my vehicle, so I attached it to my Setina bumper. It is pretty versatile in how it can be installed. The way I am showing it is actually upside down from how most people would mount it. On the roadway, the light does not disappoint. It provides adequate lighting both to the front of your vehicle and reaching out via floodlights. For the price of the light bar and wiring options, you really cannot beat Nilight as an entry into LED lighting. If you reading this review wanting to know if you should "pull the trigger" and buy it, then you should, you won't be disappointed.
Now I have only just bought this light, and haven't had it very long. Winter is approaching, and with that, we shall see if it withstands the weather. However, if it doesn't, Nilight has a two-year warranty on their products, which is also good to have peace of mind about your lightbar. Again light I said, if you're like me and wondering which lightbar to get, Nilight is a fantastic option and you won't be let down. Thanks for taking the time to read my review.

Nice unit
Set name: 5.1 Receiver
I'm really happy with this receiver even though I don't have any speakers hooked up to it. Not using it for a speaker setup might sound like a waste of a product to some people but honestly I'm finding plenty of value in it with it's other features.
The main reason I looked into getting a receiver was so I could have multiple hdmi devices hooked up to my monitor. I looked into hdmi hubs but there are a couple reasons why I've chosen a receiver instead.
1. Reliability and ease of use. Ok, so like I said I use a monitor in my room, not a tv. Monitors don't have remotes so anytime I want to change the volume or hdmi input I have to do it manually. It's a 32 inch monitor about 3 feet to the side of my bed and it's a nice arms stretch to do so. Not a big deal and while there are plenty of hdmi hubs that offer remote changing or automatic changing I worry about the reliability of those devices. There are plenty of reviews that state their hubs stop working after some months or the automatic hdmi switching starts changing inputs randomly or getting black screens and such. I just didn't want to hassle with things like that.
2. Bluetooth connectivity. This was another feature that I was looking into. Again, there are separate devices that offer this but just like hdmi hubs you will find plenty of reliability concerns. On top of that there's audio lag and previously when I bought a bluetooth transmitter I had to return it for that reason. Nice thing about this receiver is there is an adjustment for the audio to increase or decrease the audio timing but luckily it isn't an issue and the audio seems to be timed perfectly with my bluetooth headphones. It pairs up quickly too.
I haven't tried the 4k upscaling with this receiver because I use a 1440p monitor but it's nice to know that it's there. Maybe in the future I will find a use for it. There's also some neat audio presets for things like movies, music and gaming. It's actually a pretty extensive list. I suppose I should also mention that each hdmi input can be named to your liking for a nice customization feel so when you flip through them you know exactly what's connected to that input. You can even use the hdmi ports when the unit is in standby mode but you won't be able to use the bluetooth connectivity.
In the end I think this was a good purchase. It's priced reasonably and I'm getting good use out of it. Sound quality is great and the customizable features are a definite plus. More expensive than getting an hdmi hub and bluetooth transmitter but I think the reliability and extra features make up for this.

Yamaha quality!
Set name: 5.1 Receiver
Excellent sound quality. Easy setup. Complicated audio menus take awhile to master, but once you do you'll be rewarded with amazing sound. Works flawless with my 4k projector and computer. 4 hdmi inputs handles all your audio and video. The auto labeling feature is amazing. I've been using it daily for two years and it performs perfectly. You'll need an external subwoofer amp which is a bit of a let down. I bought one of the small Fosi amps from Amazon that handles the bass flawlessly. Overall, an excellent receiver that will be the centerpiece of your audio and video system. Couldn't be happier. Buy it if you're on the edge of purchasing a new receiver!

It's entry level but it does it great.
Set name: 5.1 Receiver
For what it is, an entry level reciver it is great. Haven't had it long now, about a month but it has been great. Used to own onkyo, pioneer and Harmon Kardon recivers back before HDMI and blu ray. Have used a soundbar for the past few years but finally decided to jump back on a detecated surround system. For my apartment this sounds phenomenal. I don't normally mess with the DSPs so I can't comment on those, I prefer direct sound. Could it use more power? Probably but again this is entry level stuff. I use 12 gauge speaker wire on the front 3 speakers and 14 to the surrounds and it sounds great. Front speakers are 6 ohms and rears are 8 but no trouble driving them. Dialog is crystal clear and the overall sound is warm and pleasant. Playback of Blu ray and Ultra blu ray in both DTS HD and Dolby TrueHD is such a treat, absolutely made me realize how limited a soundbar was. Music playback is fantastic, have my laptop with Jriver hooked up through HDMI for playback of FLAC and WAV audio files from 44khz/16bit all the way up to 192khz/24bit with every genre of music. Put it in direct stereo mode and it sounds blissful. DSD playback does work but only at 2.8mhz DSD64 which is still great considering the price. 4K pass through works as it should, no troubles with HDR or Dolby Vision content. Can't comment on FM or am radio playback. Bluetooth playback is alright, music enhancer does a noticible job of cleaning the music a bit, nothing extreme but does add a cetain clarity. The Bluetooth could have been a more recent standard especially since this reciver came out in 2018 but again entry level. For my Echo it is fine for the rare occasion I send audio to it. Playback of music from LG V60 over Bluetooth sounds okay but wired connection still beats wireless as far as audio is concerned and if you just playing back mp3s AAC, it won't matter, it works. 4K upscale works fine, really didn't mess with it too much because TV is normally going to do a better job of upscalling anyway. Has auto HDCP detection which is nice, allows all HDMI connections to play nice. Binding posts with Banna plug compatibility is nice to see at this price. User interface is nice and simple. One area I can see trouble with is the fact you have to go online for the manual. Again, as a entry level reciver there isn't really much to complain about.
