Re: [ARSCLIST] Balancing Amps?

[Eric Jacobs <EricJ@xxxxxxxxxxxxxxxxxxx>]

Just to be clear, the PC-2XR is an "un-balancer".  We use this for 
connecting our balanced outputs to unbalanced inputs (ie. recording 
to cassette).

Although Jensen's white paper (which is an excellent read) covers 
how to convert from unbalanced to balanced, Jensen does not actually
offer a plug-and-play "balancer".

My apologies for any confusion.

Hello Andy,

Take a look at the Jensen Transformers PC-2XR

http://www.jensen-transformers.com/pc2xr.html

There is also an excellent white paper on the subject at

http://www.jensen-transformers.com/an/an003.pdf

Let the ARSCList know what you finally choose.  We've been 
very happy with the Jensen Transformers products.

Folks,

After a long (and hopefully not foolhardy) struggle our new studio/lab 
space is nearing completion.  Now that I'm finally ready to get down to 
setting up my junk and starting work again, I need some advice from my 
fellow ARSC Members.

In addition to putting in a new space, we've also made several big 
technical upgrades around here, and one of the major ones was our jump 
from a DAL CardDeluxe to an Apogee Rosetta 800.  This stated, I'm in the 
market for a balancing amp to connect my Dragons to the Apogee.  I've 
looked at some, been directed to some and now I want to see what people 
in our field are actually using.  Can anyone share the gear they've been 
employing?

The gear I've been investigating is all below.  We need between 4 and 6 
channels total, but I don't mind achieving this through the use of 
several two channel boxes--nor do I mind spending $125-$200 a channel 
for clean pass through.  I also would greatly appreciate opinions on 
passive vs active systems for this application.

Thanks in advance!
