Hi. Quick question. Does anyone understand the thousand dollar difference between the Sound Devices 302 and the Sound Devices 442? I only need a three channel mixer, so the 302 is very attractive, however, does the 442 have better sound quality or are you only paying for the additional channel?

There are a number of things that are different between the two, other than just an extra channel. Including a crap load of outputs, variable high-pass filters, direct outputs, master fader knob, and a bunch of other stuff.

Check the sound devices website here: http://www.sounddevices.com

302 is nice and light... 442 is kind of a beast but has plenty of extra features.

I forgot who was it, but maybe a year or so ago one of the regulars here said he had called Sound Devices and asked if there was a quality difference between the MixPre, the 302, and the 442. The answer he reported was that the sound quality in general and the pre-amps in particular are the same in these mixers; what's different is the number of inputs/outputs and additional features that the more affordable (to avoid using the word "low end" for my beloved 302) models don't have.

If that's true, the 302 should sound just as good as the 442.

Man, if you can swing the 442 do it. I have the 302 and love it, but constantly (constantly!) wish I had more outputs.

I agree - I bounced back and forth on my decision and finally decided to buy once and be done with it so I got the 442. Haven't regretted it for even an instant.

I am new to recording sound properly. Why would I need more than two outputs? One goes to the camera for reference audio, and the other to a digital recorder, right?

There may be others required as well. Say you have a two camera shoot. Or you also need a mono output to a transciption recorder. Or you're sending a Comtek link to the producer and director over in 'Video Village.' Or you need to send IFB back to on-screen talent. For a working pro, the name of the game is flexibility and your next paycheque hinges on your ability to deliver at a moment's notice whatever the situation requires. It's like a parachute ... it's better to have it and not need it than it is to need it and not have it.

Biggest thing for me is to easily send a scratch track to camera when recording double system sound. It's best to bypass the recorder all together. Double camera shoots too, as Steve says. Big pain in the balls without having multiple outputs on your mixer.

Okay. I see the point you guys are making. It's a bit more than I intended to spend...but I always end up with high quality stuff...I can't seem to be happy with low grade gear. Probably a good thing, even if my wallet says otherwise. :)

Do you guys know what other peripheral stuff I am going to need? Like, do they use racks for the mixer and recorder etc, or do they use bags?

Also, in this price-range, would I be better off to look at another mixer all together? One with sliders etc? I just want to spend my money wisely.

So far for me, everything in a bag.

I've spent a lot of time and $$$ over the last few years wrestling with frugality and quality. Solid, versatile sound gear holds its value a lot better than video/computer stuff. I've yet to regret my leaps of faith gear-wise (302, 416, HD-P2, K-tek, etc). I've regretted many lesser, budget-minded decisions, however.

You can get a lot of bang-for-buck from non-boutique items, the multitude of reviews and discussion forums out there are invaluable for decision-shaping.

Everyone that has Sound Devices equipment, including me, seems to be very happy with it.

I have noted that those who have the 302 mixer would like to have a 442 mixer for the extra outputs and for the other features.

Also, those who have the 442 mixer would like to have a 302 mixer for some shoots. The main advantage of the 302 is that it is much lighter and this can make a big difference if you have your mixer (and recorder) in a sound bag.

Personnally, I elected for the 302 due to the weight issue. I would love to have the 442 for some of my shoots. I like the direct outputs which I would use to feed a 744t and still have a mixed (two-channel) feed to go to the camera.

To minimize fatigue, I have a tall chair that I use. I place the bag, with the 302 and 744t and wireless receivers, etc. on the stood. At a moments notice I can pick up the bag and be fully mobile.

If the type of work that you are doing does not require you to be fully mobile, and cost is not a serious issue, the 442 is the obvious choice.

While the 302 is called a 3 channel mixer, it does have a features that allows you to have five input channels, with limitations. If this is interest to you, then visit the Sound Devices site and read the 302 manual. (The extra two channels do not make the 302 a true 5 channel mixer.)

I might add to Dan's comments that both the 302 and the 442 have inputs that let you link multiple units together. So for those cases wehre you need 8 channels, you can combine 2 x 442s, or a 302 and a 442 for a total of seven channels, etc.

I didn't know you could combine two of the units. That's cool.

Most of the stuff I shoot is indoors, so portability is not the biggest issue. The main thing I am concerned about mixer-wise, is that I hear it is quite difficult to ride gain on more than two channels with a mixer that has knobs instead of sliders. That said, should I be looking at something like a Cooper cs 106 or a Sonosax sx-s6? I can't seem to find them on B&H, or find a price on them for that matter, but I assume they run from 4-6 grand.

SoundDevices are nice mixers, but there certainly are other equally good options out there, but likely more expensive. For field recording you can ride the levels just fine with the knobs. the 302 and 442 have two knobs for each channel, one for coarse adjustments and one for fine tuning. You don't generally want to effect a major adjustment during a take anyway, as the change in background noise is very evident. I generally try to keep it to a quarter turn of the fine tuning fader.

Oh...so "riding the levels", means to adjust them between takes? I thought they adjusted them during shooting, which, even to me, sounded like a great way to get marvelously inconsistent sounding audio.

So, say I am recording a scene in which an actor goes from talking quietly to screaming, you would adjust the levels for that, obviously. What about if he is talking normally, then gets a little louder. You would set the levels so that he wouldn't clip, than add some compression in post?

Should have done my homework. I have just bought the 302 assuming that it had three outputs as well as three inputs. Wrong.

I can't see a lot of point in having three inputs mixed to two outputs but I suppose it must be useful for something. I'd rather keep the tracks separate and mix them in my NLE.

However the 402 is too big for my kind of use so that wouldn't have been any good either.

I use the on-board camera mic in automatic for reference use if I am recording separate (double system) sound. Can't see the point in using a channel from the mixer for that.

I do interviews with two mics as insurance. For on the move kind of shooting I have been known to use two mics on my Fig Rig as a stereo pair with a shotgun mounted on it too; or a shotgun and a radio mic or shotgun, radio mic and stereo pair could be useful too ....... But the 302 is not going to handle that :-(

I got the 302 mainly for it's good pre-amps, limiters, so that I can monitor channels separately and because people swear by it. Maybe I should buy a Mix-Pre eventually, if I can daisy chain that, for more outputs.
I've still got a lot of learning to do.

One final thought - where to put the mixer and recorder? For tripod shooting (I'm operating the camera as well as trying to keep an eye on the sound) I've got hold of a spring-jawed clamp (that grips the mixer) on a bendy stalk that will mount on a lighting stand. I think that will let me keep the mixer where I can get at it and where I can see it easily whilst I am working the camera.

For mobile work I use a sound recorder mounted on my belt. I'm looking for some way to mount the 302 on my belt on the other hip. I don't want a sound recordist's bag, with all all the compartments for batteries etc, flapping around and getting in the way. SD don't sell what I need so I think I'm going to have to make something up.

Wow, how many arms do you have? That's crazy..

"Oh...so "riding the levels", means to adjust them between takes?"

Oh no. You often have to adjust the levels during the take. My point was that you really can't make big adjustments because you can hear the background shift.

Well, if an actor goes from talking to screaming and he's supposed to do so, then i wouldn't try to interfere unless he were close to clipping - which I think wold be unusual with someone who knew anything much about how to act and a sound guy/girl who knew how to leave appropriate headroom for the scene.

On the other hand, I would try to do something within reason if he turned his head slightly and the sound dropped off

I don't think the sound guy is supposed to be just an organic limiter.

Am I missing something???

Dear Spencer,

I was waiting for Ty Ford to join in.

Ty has previously stated that sometimes he has to "Ride the Levels" in certain conditions.

He went on to say that some actors will drop off in their levels when then get to the end of a sentence. By "Riding the Levels", in this specific case, he means that he increases the gain (level) as the actor lowers his volume.

All of this depends on what you are doing. If you are doing a live event that is being broadcast, or heard by an audience while you are shooting or recording, it makes sense to adjust the levels on the fly.

If you are shooting a film and you have set the levels properly while the actors were practicing in front of the camera (performing a "run through"), then you can generally leave the levels set during the take.

However, if you are recording and you see that your levels are close to clipping (in other words your levels are too high), or too low, then immediate action is necessary to adjust the levels.

In non-live events, personally, I like to set the levels conservatively so that I have the proper headroom and then leave the levels as is during a single take. But once I find that the levels are not properly set and the recording is in jeopardy, then I immediately adjust the levels.

Recording using 24 bits, as opposed to 16 bits allow you to set the levels lower to give you more headroom and still get great sound. Then you can adjust the levels in post.

Should have done my homework. I have just bought the 302 assuming that it had three outputs as well as three inputs. Wrong.

Well, mixer is called a mixer because you can mix several inputs to one output, or two, or three, whatever. If each input just goes out on its own output, it is just a levels setting device, not a mixer...

302 and 402 are designed for situations where there are more inputs than available recording channels, typically in eng or documentary situations where only the camera is used for audio recording. For that reason they have only 2 outs. If you want to record all mics separatelly, you do not even need a mixer, just a multitrack recorder.

I didn't know you could combine two of the units. That's cool.

Triple to quadruple those numbers, my friend. Didja hit the lotto <grin>?

I am relieved that I can't afford one of those right now. Haha. I really didn't think a six channel mixer could be so expensive.

Hi folks

More on the topic of his riding faders.

I prefer not to ride the faders during a take as mentioned above you change the background ambience, but i have also found problems.

I was doing a recording for a known comedian, during the blocking and rehearsal I set the levels so they were on average around 5ppm/+4dbu/0vu/-12dbfs - Now SQN d not have coarse and fine faders, they only have the coarse faders...

Now as for head room its common practice for the range over good signal to be between

-18dbfs/-4vu/4ppm/0dbu minimum and -10dbfs/6ppm/+4vu/8dbu maximum, this leaves little room for much tweaking, if im worng please correct me!

now during the block i set these levels as stated above to be around but then during the first take the actor shouted which he had not done prior, this resulted in clipping.

Each take was inconsistant delivery on this particular line so I found the only way was to anticipate him and ride the faders for this delivery.

Am i wrong though in saying that its bad for a dialogue signal to drop below 4ppm/0dbu/-18dbfs
Sound devices meter orange section which detemines good level on the 302 and 422 is quite limited and the SQN feels more limited as you can only go from 4ppm to 6ppm.

I monitored both signals from the mixer and camera, and both levels sound clean and strong even when peaking around 4.5ppm but this could be false from the headphone gain

But i feel it is unprofessional to clip at all, I feel I have failed to an extent if i clip.

Any advice on this matter further as to where levels should not drop below, or ways to combat unpredictable changes in actors level?

Hi Lee,

There's a couple other things to consider on levels...

24 bit being one (for being safe letting the levels be lower) and limiters (for film dialog, I basically never turn them off just as a safety feature. 20:1 ratio on the 302 and 442 so just setting a -3dBFS threshold gives you 60dB of protection.)

Others with more experience can jump in on specific levels. But your guidelines sound right from the work I've done.

Hi Alex


During the shoot, I had the limiters on, but on the SQN im not sure whether they effect the in and out, or just the output.

It might even have clipped at the mic stage...

If it doeasnt effect the inputs that would still result in clipping wouldnt it?

Also i could have used the attenuation switches but they cut it by a large amount so for the generaly doalgoue it would have been almost silent..

It was a tricky one indeed, from general level to a burst of loudness, really as long as it didnt distort the mic diaphragm the mixer limiters sould have stopped it clipping but they didnt.... i was using the SQN 4s iVe just to be clear on the mixer :) which only has course faders too. Unless ive missed something on the mixer....
