Thanks for your patience sticking with this thread. I could probably pop down to the (not so) local music shop and have these questions answered but would be $20 poorer from buying gas.

I looked at the preamp

https://www.sounddevices.com/products/usbpremaster.htm

but couldn’t download Adobe Reader, to read the PDF on it.

Questions:

1. If I feed two separate signals into the xlr inputs of the Sound Devices preamp will it output two separate channels (tracks?) of audio simultaneously via the USB?

2. Will Adobe Premiere recognize it as two tracks and not one mixed track.

If not

3. How can the other Sound Devices digital outputs (ports marked S/PDIF, PC audio) be captured onto my notebook? Some sort of adapter? My notebook only has firewire and USB and the analog MIC input.

4. I don’t think two separate digital streams can be captured by a notebook?

After further research I’ll probably be getting a Sennheiser MKH 416 that’ll work for now and should match

the quality of the someday to be unleashed Red Scarlet. Based on the MP3 recordings of the Sennheiser I’ve heard it sounds great.

Some forum indicated that the Red One does better with a line level input, I’m guessing because thats

because the internal camcorder preamp gets bypassed? Assuming (big assumption) that the Red

Scarlet has similar audio recording capablities, I should look for a preamp with line level ouptut…

1. Do all standalone preamps put out line level signal?
2. What is the port/connector/cable called that uses line level signal
3. Is there a standalone preamp that puts out both line level signal and a usb signal?

I couldn’t find one that does both.

I know you recommended the Sound devices 302, but its kinda expensive…

4. Is there a preamp with usb and line level signal output that matches the quality of the Sennheiser MKH 416 that
does both USB and line level signal output? Preferably one under $500.

5. If I am recording to my notebook (with the previosly mentioned recording equipment) and am listening to the recording (after capture) via analog headphones
will I be hearing the full quality?

I’m guessing no.

6. The digital to analog conversion in the notebook is bad?

7. Is there a digital headphone that when used with my notebook would represent the recorded signal? Make, Model?

8.I am guessing the bit depth, and freq. response of the digital hardware are not so good in the notebook?

Thanks so much!

Thanks so much for your input. After reading your post and further research on the net I’ve learned the Canon HV20 really needs a preamp and the Juicedlink cx231 seems to be whats needed.

Since the Juicedlink provides phantom power it could potentially be used with a high quality studio condenser mics (Rode nt1a) for recording to the camcorder. Yes?

I guess my goal in wanting to record everything to HDV tape is to eliminate one piece of equipment (the Centrance preamp). And archiving to tape is a benefit over hard drive.

Question:

1. Is the HDV audio recording specification sufficient to record VO say with the Juicedlink and the Rode nt1a? In other words is the HDV tape a limiting factor?

I see the specs for the Centrance are 24 bit @ 96khz.
I can’t find the specs for the Canon HV20 audio bit depth and sample rate.

Specifically I’d like to make something like the Proctor and Gamble graphics at 2 minutes 35 seconds.

[Craig Seeman] ” much better codec (xdcam)”

I’ve seen similar statements in this and other forums but I am unclear as to how the Sony EX1 codec is better than the hdv codec.

HDV
4:2:0 long gop
25Mbps CBR
1440×1080 60i

SONY EX1
4:2:0 long gop
35Mbps VBR
1920×1080 30p

Can someone explain how cramming 1920×1080 30p into 35Mbps is better than cramming 1440×1080 60i into 25Mbps?

Does the VBR max out at 35Mbps or is there a range, ex:15Mbps-50Mbps?

Admittedly my Subject title is a bit inflammatory (just to get your attention), but I really only want the answer and not a flame war 🙂

There is also this unit for $17000:

It works with FCP and Adobe Premiere. Are you aware that your camcorder does not output audio via HDSDI?

[Jeffrey B.] “The XHA1 will give you a better picture, hands down.”

Could you back that up with some resource(s) please. A link perhaps.

While what you say MIGHT in theory be true, I have read otherwise. The HV20 uses a CMOS sensor where the XHA1 uses CCD’s. I believe someone reported in the HDV forum stating they could see no difference between XLH1 and HV20 footage (in good lighting)suggesting excellent image quality indeed. I have the HV20 and would like to hear of some side by side comparisons.
