When does shipping begin? Warranty terms?

How about giving a features/spec run down.  I really don't feel like reading through all these pages .

Anyone done beta testing in the field?   Has it been crotch tested?

I'm now starting a BACKUP LIST. Just PM or email me. (Need an email address so I can notify you.)

If someone backs out from the WAITING LIST, due to circumstances beyond their control, people from the BACKUP LIST takes their place.

Thanks for the support.

Told ya so

Yah..   And the part I specifically remember the most is how this is going to suck up all my time. 

Selling kits are way way more attractive for me than spending nights soldering and building finished units. I'm looking at ways to further reduce assembly time. (Eliminating wiring is on the top of my list.)

. . . what's the deal with 1A?  I thought you were at 170mA?  Wouldn't 300mA do?

Price difference in AC adapters are not much and this seems to be the most common model out there.

Didn't I read somewhere along the line that this pre will run off of a variety of DC power supplies, including the 9v Lion DVD batteries?  Or will it require a 12v SLA or Tekkeon power pack?  I want to get my name on the waiting list, but first want to understand what it will take to power this beauty in the field (for a whole day of festival taping).

[fivefishdiy]

Yes. I've tested it personally with the Tekkeon battery.  Dialing the Tekkeon voltage selector, 6V to 12V works. Though at the lower DC voltages, the pre may not reach the full 48V output for phantom power.  (I don't think the 48P is an issue though, cause most condenser mics will work even down to 18V or 12V phantom power).

Battery life depends on the mAh of your battery, and whether VU meters are ON or OFF, whether you're using 48V phantom power or not.  I wrote down on the board what I got for battery life... will need to look it up.

[JasonSobel]

Or will it require a 12v SLA or Tekkeon power pack?

there are also several options for 12v battery power without going to SLA or the Tekkeon power pack.  I personally have a 12V NiMH rechargeable that I currently use with ym HD-P2.  If I choose to try out this pre-amp, I'd probably use something similar.  (something like this: http://www.batteryspace.com/index.asp?PageAction=VIEWPROD&ProdID=2387... just hack off the end of the cable and solder on whatever is appropriate...  just an example, there are many out there.)

Though at the lower DC voltages, the pre may not reach the full 48V output for phantom power.  (I don't think the 48P is an issue though, cause most condenser mics will work even down to 18V or 12V phantom power).

Some mics have problems with less than 48v.  Schoeps cmc6 bodies can operate on 48v or 12v.  But voltages 'in between' are not supported.

It'd be interesting to see a curve of input voltage vs. phantom voltage (under load). 

[fivefishdiy]

O-canis, I just reconfirmed... a 9VDC input to the preamp will still give you 48V phantom power.

12V --> 48VPP
9V --> 48VPP
8V --> 48VPP
7V --> 48VPP
6V --> 45VPP

[jerryfreak]

i vaguely remember way back in one of these threads that this unit had really impressive power stats, like less than 500mA at 9V.

did something change? whats the power consumption sans phantom?

[dactylus]

Looking forward to the new TS-2...

+T for your efforts and craftsmanship!!

 

[fivefishdiy]

If I remember right, 2 channels with PP ON, using 2 condenser mics (CAD model, 8ma each), all VU meters lit up, the power consumption was 3Watts @ 12VDC.... so that's 250mA.

From there, it goes down to 1.5W if PP is OFF and VU meters are also OFF. 

So at 9Volts, doing the math will be 3w/9V = 333mA   (or 166mA if PP is OFF and VU meters off)
Will try to get actual readings for 9V one of these days.

hey fivefish

just wondering what type of connector you put on your preamp for dc power.

thanks
