The preamps are stellar (For me the best), but this tone is very annoying (Very low level but easy to hear) (I noticed this when I record music or low sonority ambiances), I tried in two 4Minx (My unit and another newer), and both exhibit the same problem. I sent my machine to Aeta, according to Aeta was ok (IMMO maybe is a unresolved spray problem from digital side to analog)

Is a fft from my Soundfield SPS200, taken from the file that I uploaded to Soundcloud. The high frequency peak is due the combination of the four channels (The fft is a 4 channel combined), and the low frequency peak from the ambience, the problem is the peak in the middle, is easilly distingable (The file was normalized for make it more notorious). The problem is hughe at low gain (0dB), with more gain is hardly to hear. The microphone is ok, no noise in other recorders, and with the AETA I had the tone with all microphones that I tried The 6dB oct curve is due the Nuendo (more lineal than logarithmic)(flat with white noise)

I tried two units, and both have the same noise. I heard this tone when I recorded music. At the finish of a song, when the sound of the instrument disappear the tone is noticeable.

I don't recommend the Aeta 4Minx in any way, I had one and I'm very lucky for sold it. IMMO have a awful metadata, no serious surface faders, sluggiest interface I seen (Is not capable of show the TC frames), a slow mirroring (Slower than the Maxx) the ambisonic converter won't work properly, have a horrible low level tone at 1490Hz (Easily audible when work at low level). His favor point, the best preamplifiers I heard in a battery operated device Best

Primary Zaxcom Nomad, spare Zaxcom Maxx

In my opinion the beamforming will be his success, the possibility of change the directivity in real time for focus the source (By an array of mems)

In my case with the Soundfield SPS200 is unnecessary, the capsules are very very close

I'll stay tuned about, I have my reserves. I have an accident with my SPS200 and drop to the floor, I taken a measures against a DPA 4007 for evaluate the damage. I surprised about how close are the capsules and how flat are. The damage was cosmetical, but a sent to Soundfield for change the shell of a capsule, and they replaced all for a new set. Best

The Harpex do a upsample the FOA to HOA, IMMO this plugin is the best investment for ambisonics. Jose, have you calibrated your microphone at Core? Best

I don't have (still) any problem, I'm in Europe. But I have the curiosity about my Zax tramsmitters/receivers (TRX2.5 and TRX900LT I'm poor). Curiosity about the US mono, EU Mono and XR

Just was a question to the manufacturer, even the new models are older than the new rules. In other hand, old and new have to mono modulations (Apart of HD that are narrower), US and EU, IMMO almost the EU could work with the new rules. I don't know about XR

My question also had transmitters (between brackets)

Means this that the QRX100 and RX4900/RX900 does not comply with the new regulations? (And TRX900AA, TRX900LA, TRX2.5....)

I ask the same question to RF Venue several times, no way

IMMO is: In My Modest "Oppinion", just "Oppinion" But just making random assumptions: IMMO Rode make entry level microphones (with some nice ones like the NTG3), I don't expect anything more than this, and... I ordered one for try
