So I've got some range tests which I will attach here.
They're all Polywavs so I recommend using Waveagent or ProTools to listen to them.
Each test was slightly different but there were some constants. We only used whips for all of the tests. The transmitters were all on 50mW and all the mics were black dot Sanken Cos-11d's. All frequencies were scanned and co-ordinated. All wires were recorded by a Sound Devices 688.
I'll break down my personal comparisons here but let me first start by saying that unfortunately we didn't have the new A10-TX - instead we were using the A1010 as that was all that was available at the time of testing. Yet despite not having the new limiter and pre-amp the Audio LTD still sounded by far the best. This also meant not being able to test the 48v function or the remote bluetooth capability.
The first we stood outside about 6 meters away from the front door while we sent our guinea pig (Alex) into the dBAV store (a concrete building roughly 20m long).
This was an exterior test where Alex walked about 40m down the sidewalk with line of sight the whole way. There were perhaps a few tree branches and sometimes people in the way but overall it was clear line of sight.
Basically the same as Test 02 but here we switched the Zaxcom Transmitter to ZHD 48 modulation.
For the Lectro we used an LT transmitter being recieved by an SRc (relatively new serial number). The Lectro performed possibly the best in regards to range. The dropouts did have some annoying artifacts which may be difficult for post to remove. Also not having any recording functions obviously hampers the system somewhat. Overall the Lectro feels like the bare basics get the job done kind of system. No bells and whistles, no fancy screens or complicated menus but just great range and solid usability.
Zax was an interesting mixed bag. We noticed lots of delay compared to the other two brands - both in XR modulation and ZHD. That said the sound quality was definitely a step up from Lectro. There seemed to be more low end and the high frequencies were a little less sharp. That said it did seem to be missing a little bit of high end compared to the Audio LTD (probably due to it only transmitting up to 16kHz) but this was barely noticeable in real world application.
We did notice the reciver screen was very hard to see in direct sunlight. You had to use your hand to block the sun and even then it was a little tricky.
In XR modulation the range wasn't great - being out-performed by both the others. When switching to ZHD the range improved markedly however the latency was a touch worse (around 7ms apparently).
The dropout on these units sounded worse by far. They made awful digital squelches and squeals which made the audio truly unusable when it did drop out.
Obviously the functionality of these units is unrivaled. Having Zaxnet built in offers you so much flexibility.
The sound quality of these was great. I've never heard a Cos11d sounds so good. I'm sure with a DPA lav they would be unrivaled in sound quality.
Range was relatively close to Lectro which was nice to see. That said there were definitely instances where the Lectro were outperforming the Audio LTD in range. That said there were other times that the Audio LTD were doing better than Lectro so it often seemed much of a muchness. The dropouts on these units sounded great to me. There didn't seem to be any artifacts like clicks, pops or digital squeals. Instead the audio just cut out and came back very quickly.
The receiver screen was great to look at in the sunlight. Due to the reversible screen you could face it directly towards you and see it without issue. Flicking through the menu seemed relatively intuitive too.
