Title: New Rode Wireless Go II dual transmitter system also records in stereo

I wonder whether the release of this device has anything to do with the Hooke Lav device being discontinued.

In essence, it's two long-range wireless mics, together with a dual channel wireless receiver which can output to just about any recording system (phones included), but the transmitters (which can accept 3.5mm mic inputs as well as having their own omnis built in) can themselves record.

At a stretch this could be relevant for stealth concert taping (have a couple of friends standing spaced apart - socially distanced! -  in a good location with the tiny transmitters, and you could be recording to a phone elsewhere in the venue), but in any event, it looks like a pretty neat and cost-effective little rig.  The sort of thing that I wish I could think of an excuse to purchase...

It does look suspiciously similar to the now-defunct Hooke Lav system.  :hmmm:

Very light on specs on what is going on under the hood on the digital side. How much is the audio being compressed by the transmitters?

Safety tracks are surprising to see.

Yeah, I’d be curious about the specs.  I’d be interested in using the transmitters for a board feed when the board is on or behind the stage, if the quality is good enough.  Avoid having to run cables across the room.

By the way, I've emailed them to point our that their adverts and help pages are totally confused between mono and stereo - for instance,

"When there are two meters, you are in mono mode. This means that each transmitter's output is being recorded onto separate channels (left and right) on the Wireless GO II’s output, which can be processed individually in post-production. This is great for two-person interviews where you need to be able to edit and mix each sound source independently.

When there is just one meter, you are in stereo mode."

Graphics illustrating mono and stereo working are also garbled.  Hopefully that's just the usual problem of marketing people trying to understand what the tech people have created...  As for specs, they mention 24 bits and 48kHz but that's obviously not the whole story.

....

When RØDE introduced the original RØDE GO two years ago, the comments sections on their social media channels where overflowing with request from videographers wanting to be able to receive two channels instead of one. I think they are answering that demand.
That the transmitters have recording capabilities makes it a very interesting product, especially in cases where there may be interference in the transmission - which was not uncommon with the original GO.
It looks like the associated app has the ability to visually identify gabs or interference in the transmission.

According to the B&H video on this system, audio can be exported from the transmitters in 32 bit float...  That video actually explains a lot, see https://youtu.be/Opd0qfjhNvI and also Rode's own videos (2 of them).

Wow, I am MUCH more impressed with this product after watching that video.

The big unanswered question for music recording is the dynamic range of the 3.5 mm inputs on the transmitters given that this system seems to be aimed at speech recording.

Also, I wonder whether the 32 bit float is just 16 bit with zeros added... or am I being cynical?! 

I guess one could make up a suitable Y lead to connect a stereo mic to both transmitters.  Or something.

Gear lust.  Don't you just hate it?!

Can the inputs handle a line level? Also it seems like running two units into one receiver will introduce an alignment headache with different clocks, but i don't know enough about it to understand.

I'll wait until Sony comes out with the 32 bit A10, but this product is game changing for two person interview format video.

At least Rode presented a new firmware update which offers the recorders to be recording on their own without transmitting.
Turning them into mini field recorders.

per the current datasheet (https://edge.rode.com/pdf/page/88/modules/425/WirelessGOII_Datasheet_2.pdf) the max input is -20 dbV. so you'll be padding a line signal quite a bit

as an aside, a 32-bit A10 will add nothing over the 24-bit version that has a dynamic range of around 16 bits (https://taperssection.com/index.php?topic=192831.msg2332090#msg2332090)

it is, basically. it doesnt record in 32-bit. it exports 24-bit in a 32-bit float format

i asked Rode support about the PIP specs. they said 3.1V but did not specify at what resistance

when i asked "at what resistance" they provided this fabulous non-answer: "3.1V is measured when connecting a lavalier microphone. However, the load usually drops the voltage as it pulls current. Unfortunately, this is the only information we are provide by our engineering team."
