Spend much time on location as a production sound mixer? Spend much time in post stacking hundreds of tracks of which perhaps a dozen were recorded on location? Applying noise reduction?
I will be the first to say that on a single track, with a quality microphone positioned correctly, that a track recorded on a $14k Zaxcom or Cantar and a track recorded on a $300 budget recorder will not sound like $13,700 worth of difference. Will one have less noise, better clarity and definition, you bet.
But start stacking tracks, and applying noise reduction, and these nasty artifacts have a multiplying effect and it's not long before your soundtrack has lost quite a bit of fidelity and definition.
Additionally, those knobs and meters and switches provide functionality and flexibility that carries nearly as much weight as the sound quality. Dealing with multiple camera returns, ifb and village feeds, multiple iso tracks, multiple mixes, pfl monitoring, all while carrying your entire toolset on a harness makes for a pretty specialized piece of hardware. This is where the argument for a dedicated mixer and separate recorder pays off. Location sound is a very demanding and dynamic work environment. The ability to reconfigure, reroute, and manipulate numerous sources and sends equate to efficient use of time on set, and when on location, minutes are worth their weight in gold.
Also consider the environmental issues these tools face on a daily basis. High humidity, extremely high and low temperatures, dust, vibration...and it still has to sound great. Remember, these are not studio tools. And all those knobs and switches have to operate in these conditions tens of thousands of times without inducing switching or scratch noise into the track. And those meters have to be viewable in bright direct sunlight, or dimmed to not distract when working in sometimes nearly complete darkness. Oh yea, and it has to run on battery power sufficient to provide at least a few hours of use between battery changes.
I'm not sure what kind of engineer you are, but as an aerospace engineer, I'm suprised that professional location sound gear can be produced and supported at the price point they sell for.
I carry a PSC Alphamix, built in 2003. PSC has serviced this mixer once since I've owned it, for cleaning and replacing/upgrading the power distro section. The total bill was $90. Shipping costs more. I can call PSC and within an hour or so, get a callback from the owner of the company who knows this gear inside and out. Try that with Sony or Tascam. So, yea, they cost a lot of money. And low prices recorders are in their own right amazing at what they can do. But there are far too many differences between to two to make any kind of comparison.
Like Zim9000 I am also in the market for a low-end recorder such as the H2, DL-05 or DL-07, etc. But being an engineer I also have my doubts that very high prices produce very high quality. Likewise subjective assessments.
What I’d like AlcoveAudio to say is precisely where these low-end devices fall over, quite apart from the obvious greater flexibility and adaptability of the high end recorders. More knobs and meters and other adjustments don’t necessarily affect the overall sound ‘quality’, just the adaptability of the machine to the recording challenges of the day. It also seems unlikely the suggestion that the sound capability of these cheap recorders is little better than an average DSLR camera.
If basic sound quality is the issue, have either Wheatgrinder or AlcoveAudio set up in their studios, their own chosen microphone set-up (stereo for simplicity) feeding the resulting sound into one of these cheaper recorders and also parallel it to their chosen recorder at say ten times the price? Can they tell the difference when played back on a decent set-up for both? If they can, are they able to translate this difference into measurable parameters such as distortion (all types), frequency response, dynamic range, noise floor, quantisation noise, etc.
Such figures appear to be absent from most such machines nowadays, making comparisons on these factors impossible.
I’d be interested to hear if I am talking just rubbish, quite apart from helping to decide my purchases in the future.
