    1. Review of Arbiter Open Mic Comm System

      Posted by Tom on 12th Jun 2017

      Independent review - purchased from refereestore.com - no incentive to write a review (although happily open to bribes)

      Overall View:
      I’ve found the Arbiter system to be a solid set of communications devices which help the referee crew communicate. The devices are an excellent training product, and workable for matches, but you do get what you pay for. More on that later.

      Packaging:
      The radio set arrived in three individual soft-shell cases, each containing a radio, headset, charging cable, and armband. The cases are jus slightly too small to easily shut, but can carry the devices without issue. A set of directions poorly translated into English is provided with each set. It’s a bit tough to read through, but the basic setup works okay.

      Setup:
      For a three radio set, do the following:

      Turn on the radios. Hold the + and - buttons together for ~3 seconds; this clears the connection memory of the devices.

      Hold, for 3-5 seconds or until the LED starts flashing, button A on one device, and button B on the second device. Once the LED is flashing between red and blue, press A on device 1. Do nothing with device 2. Wait a few moments for the two devices to link up; the LED will blink blue when connected. Key step that I missed repeatedly: once the devices are linked, press A on device 1. This starts the intercom mode and truly finishes the connection.

      Once devices 1&2 are linked, repeat the steps on devices 2&3 (Device 2 hold A, device 3 hold B, etc.) Don’t forget to press A after linking devices 2 & 3.

      If done properly, device 1 will have a blue LED, device 2 will have a half blue, half red LED, and device 3 will have a red LED. The radios are now connected and ready to go.


      Radios:
      The radios have a single TRRS-style port to carry power, mono in, and mono out. I’m unsure of the pin layout, and have not been able to use other headsets with this radio.

      The radios are certified to be water proof and dust proof, holding a IP65 rating, although they are not submersible. We had no problems with them in a heavy downpour.

      The button layout on the radio receiver is quite simple. Off and On are obvious, and require a ~3 second hold to activate. + and - serve as resets for the connection memory, as well as volume control once connected. A & B are used to connect devices together.

      I am not sure what radio bands these devices work on, but have not run into any issues with commercial or personal radios. A scanner could probably pick up on the signal, if someone really wanted to listen in.

      The signal from these radios has limited noise reduction, meaning that the full blast of the referee’s whistle is blunted. The spoken word carries through without reduction - a shouted call echoed loudly in my assistants’ ears, whereas my Valkeen and Sonik Blast were much more muted.

      Battery life appears to hold up to the quoted ratings, at least after a month. I had no issues syncing radios 20 minutes before my first match, and then using them through 3 matches. As there is no battery indicator, it may be tough to tell when the battery is about to die. Charging seems to also match the quoted 3 hours for a fully-drained device.

      Volume on these devices can extended into painful territory when cranked all the way up. There should be no issue hearing each other. Each device controls its own volume; there is also no way to temporarily mute your microphone.

      Headsets:
      The default headsets for the Arbiter system are reversible, over/on ear mono sets. The earpiece can go into either ear without issue; the boom is short enough that it does not need to be taped. After a month of use, I’ve found the boom to have loosened enough that it needs to be adjusted up every 15 minutes or so; I fear that it will continue to loosen over time.

      Unlike other competitors, the earpiece is not customizable and does not go into the ear itself. The earpiece on this device is a small, on ear piece that fits over the ear canal entrance. Pictures from the Ref-comm devices are very similar in earpiece design; the boom microphone is much shorter. Both the earpiece cover and mic cover fall off easily and are easily lost. The earpiece can have issues staying in position if you wear glasses; a quick touch to reset it is easily done.

      Armband:
      Nothing special here. The armband was adjustable to find the formidable forearm of my AR (seriously, those thews are impressive) as well as my much smaller forearm. The receiver fits into the holder and the headset wire has to wrap around the bottom. A small hole in the bottom of the armband would help with positioning here. The armbands do keep the receivers secured in wet weather and hard sprints.

      Range:
      Make sure that the referee (or center) has device 2 (the one linked to the other 2). I would estimate the effective range to be more like 400m-500m, when under a shirt sleeve. We had a good bit of static testing them out today when we had otherwise clear skies. I had device 2 as AR 1.

      Pricing:
      The 3-unit Arbiter system was $700. I would rate this as an excellent price for an association to provide radios for mentoring or youth purposes. The cost is low enough that you get an excellent educational tool. Of course, you get what you pay for. When you consider that the Ref-Comm system starts at $400/radio, the Ref-Talk system is ~$550/radio, and the Vokkero system is $1150/radio… well, there isn’t much more to be said. Smaller receivers, customizable headset, alternate, encrypted channels, and better filtering all come with a cost. Depending on your usage case, of course, will make your decision easier.

      Wishlist:
      I look forward to using this system with youth referees in my area as a mentoring tool. I’d like to see alternate headsets available, perhaps ones with in-ear pieces or longer booms. They may be compatible with the RefComm headsets; I don’t have any to test this out. A single case, custom fit to the set that is ordered, would be fantastic. A better armband holder would be a plus.
