20 Questions with the Sound Devices 633

It is possible to plug wireless receptors in channel 4,5,6?
How can I adjusts volume with this wireless in channels 4,5,6?
Hi Mario,
Yes. The software trim on inputs 4, 5, and 6 ranges from -30 to +16dB, and the fader can add an additional 16dB of gain. That being said, most professional wireless receivers will have a variable output level. For example, the Lectrosonics UCR411A can be adjusted in 1dB increments from -50dBu to +5dBu. Between those three stages, it should be quite easy to get a clean and healthy signal level.
Connect the output of your wireless receiver to the TA3 input on channel 4, 5, or 6. Depending on what kind of output your wireless system has, you may need to purchase a cable that terminates in a TA3-female connector. From there, tune to taste! I'd begin with everything at 0dB, adjusting the wireless receiver output first, the trim second, and fine-tuning with the fader.
I have tested the 4,5,6 line level ta3 inputs with Lectrosonics 411A's at +5dbu and there is more than enough gain there to smoke your ears for good. I find it is actually a little better than the 664's 7-12 Lin in's.
Hello,
You may leave the track inputs 1 and 2 in microphone signal and 3, 4, 5 and 6 on line inputs?
The idea is track one, boom, track 2, wireless mic, 3,4,5 and 6 line imputs from a mixer.
Thanks for the reply and greetings.

Hi Carlos,
Inputs 1 - 3 are mic/line switchable, so yes, you may have inputs 1 and 2 at mic level while 3-6 are on line level.
Thanks for your question!
hi output x1 x2 send out?
1-2 to main out (with pan l r)
x1 3 -4 (balanced or unbalanced) or 5-6?
x2 3-4 or 5-6 or tape out
for me set up need 4 direct out its possible?
Hi Luis,
If I understand your question correctly, you're asking if it's possible to take 4 balanced direct outputs from the Sound Devices 633. The answer is yes. Here is the easiest way I can think of. For the sake of symmetry, I'm going to use a pair of mic inputs and a pair of line inputs. You can apply this to whichever inputs you like.
Pan channel 1 hard left. Pan channel 2 hard right. In their respective PFL menus, disable the X1 and X2 routing. Make sure none of your other tracks are routed to LR Mix. The main XLR outputs are now post-fader direct outputs.
In their respective PFL menus, pan channel 4 left and channel 5 right. Route channel 4 to X1 and channel 5 to X2. Pre- or post-fader is your choice. Double-check that these tracks are not routed to the LR Mix. The TA3 X1 and X2 outputs are now direct outputs.
If you're also using channels 3 and 6, make sure they're not routed to the LR mix or the Aux buses. And luckily, the 633's monitoring menu makes it easy to send any combination of tracks to your headphones.
Hope this helps!
I have a 722T. Should I upgrade to this? What would I lose? How do the preamps compare?
Hi Eugene,
I think it'd be best to talk to one of our salespeople about whether you should upgrade. A decision like that deserves a conversation about your specific workflow.
The preamps in the 633 sound great, very clean and quiet!
I think you got some measurements wrong in the video: How is the Nomad only 1.1 cm wider than the 633? That doesn't make sense.
Hi Rasmus,
I used the mfr specs for the dimensions. I double-checked that I copied, converted, and spoke them all correctly. Thankfully, it all matched up.
I pulled out the tape measure and here's what I found: Sound Devices measures protrusions, Zaxcom does not.
The 633 is 9.25" (23.5 cm) wide when you take the battery and media doors into account. Its average width, however, is more around 8.75" (22.23 cm.)
The Nomad's chassis is 9.9" (25.15 cm) wide, but with protruding connectors taken into account, the unit has a maximum width of 10.63" (27 cm)
I'm gonna side with Sound Devices on measurement style. For the purposes of fitting a mixer into a bag or case, I want to know the actual clearance I'll need.
Good eye! I'll go nuts with the tape measure and publish a correction later on today.

You say the 633 does not offer T power. According to the tech specs on the Sound Devices website the 633 offers 12v phantom power through 680 ohm resistors to any of the analog inputs. Is that different from T power?
Hi Tom,
While also requiring 12v power, T-power is not the same as Phantom power, and the two are not interchangeable.
Sound Devices has a great write-up about it, and how it differs from Phantom Power. They say it better than we could, so we'll send you their way:

Take care!
Thanks for that clarification about T-power.
So it seems phantom power and T-power are pretty much opposites in the way they supply power - T-power supplies power across pins 2 and 3 and phantom power supplies power equally across pins 1-2 and pins 1-3 with no power across 2-3.
That explains why the one time I forgot to hook up the T-power adapter to my Sennheiser MKH816T I got no signal at all (and thankfully no damage!)
Is it true the sound devices 633 can't do a mono summed return? How do you do this if it's possible?
Cheers
Chris
Neither I nor the transcriber I just worked with can read the MP3 time code using QuickTime 7 Pro. I'm recording at 24/48 .WAV poly to Isos on the CF card and 128 kbs to L/R on the SD card. QT7 can see a rounded off start code in the Inspector and Properties windows but no running code. The drop-down box around elapsed time is not there. Thanks in advance, ab
Hi,
I'm worried about using inputs 4 to 6 with my wireless microphones because I did not see if there was the same input limiters as for the XLR 1 to 3 inputs. What do you think?
Thanks
