Some Audio Testing Results

[Stuart English]

Can you choose to set all four channels of audio in the camera to record from one of the inputs?

No Finner, its a direct 1 to 1 patch of each mini-XLR into its A/D converter. But an alternative is to create a Y cable with a full size 3 pin XLR at one end and two 3 pin mini-XLR's at the other. I'm making one up today....

Hi there. . .

My concern about synch was from JFirestone's comment a missing second in there somewhere. It seemed odd, so perhaps I have misunderstood him, but I'm glad to hear of OffHollywood's long-takes results.

I am deeply concerned about the hiss issue. . . there isn't any hiss in my HVX.

calm down, one guy make a statement (a wrong one btw- and then everyone freaks out)

This is the first firmware with audio, I have confidence it will be fixed.

Stuart,
The Y cable is an ok down & dirty solution for line level only. The best solution is a 1 “in” 4 “output” line level adjustable distribution amplifier.

Most professional cameras only gang 2 channels not 4.
Best advise is use a mixer and a trained audio tech. whenever recording sound.

Thanks for the response Stuart. So are you saying there is no way possible to record 1 input to more then 1 recording channel? This can not be done with a firmware tweak? It is a common feature that you can find on DVX cameras right up to F900 series.

I totally agree Greg hire a sound crew whenever possible. Thing is sometimes a person does not have the $ for a sound crew and this is a good work around when you do not have a sound crew. Really the camera should have external audio pots like every other camera but with red deciding not to do this the suggested feature I mention would at least be a work around for no audio pots.

For me, this is a sign that RED needs to improve its design once again. A camera should be able to record decent audio w/o a sound man. Something is fundamentally wrong here. A DVX can do it, RED should also be able to do it. It's not that tough.

I'm confident Jannard and team will get this sorted out eventually.

It is not a phantom power issue, or line or mic. I don't know exactly what it is, but we are sharing information internally and dealing with it immediately. I am here at RED as sort of a "uber" user, and share what I discover with all of these really smart people that Jim hired and then they figure it out.

Stephen, what exactly are you curious about the audio synch?

It's good to know that there are people like you there.

I haven't had a chance to check the hiss issue to see if it is on the files themselves. It is possible that what I was hearing had nothing to do with the hiss that others are hearing, and could be only on the headphone output, but it seemed to be tied to phantom power. I will check my files, and try to replicate the results. (I haven't been able to replicate the results we had with the phantom power.)

But the thing is, the Red One is revolutionary because it allows you to do things you could only manage with much more expensive cameras before.

This would be the opposite. Something you can do with a lot of HDV cameras, but not with the RED. And it´s not some "Why dont we have autofocus" - semipro - issue.

I´m sure Red will sort out the hiss thing (even if has something to do with shielding the ADDA convertors. That´s not going to be trivial).

The recording of one input to multiple differently gained preamps spells hardware. I would think.... That would be a bummer. Dont want to solder Y-cables or attach another box to the camera.

Cheers,
Jochen

Of course I'm still in favor of physical gain controls and a built in limiter. It would be nice to see this camera match the capability of the DVX / HVX and other cameras in the area of having a quick and easy knob controls and a limiter to soften peaks.

10s, I would disagree. The HVX camera needs the extra physical interface for all those shoots where the shooter simply hooks up a mic or there is no recordist watching levels. The RED One is designed to work as a cinema camera meaning there is almost always a recordist. Once levels have been matched between camera and mixer, there is no more need to make any changes, hence no need for easily accessible level controls. (My .02.)
