So start with a little reminder of this lady:
4 in XLR preamp with 65db
4 in line
8 out very
2 out master TRS
SPDIF in and out
8 in and 8 out ADAT
Firewire 800
Thunderbolt option.

For now my tests only apply to analog inputs and outputs, and SPDIF (ADAT is a good month) with vocals, bass and guitar.

I use a Dell QuadCore with 6G of RAM.

I put 9 because the ability to connect multiple Apollo cascade is not possible or it is still (in addition to its stability) the big plus firewire.


After spending the headlock when installing the PCIe 800, are different can not be more stable but one sinequanone condition NOT SLEEP! when the computer goes to sleep and you wake up, a nice message informs you that this device is not made for and so you have to restart your computer. No big deal.

Until then, I max is 4 simultaneous tracks with 4 Fairchild670-1 Engl UAD610-1 RealverbPro-3 (in the) to insert and no worries: virtually no latency.

Updates .... y'en had 2 I think since I took my UAD-2 Solo in 6 months.


Installation is quite long but once it's over, it's more than happiness.

The DSP allows so many choices that it's almost enjoyable (yes yes!)

- 16 in each insert with 4 live for the happiness of recorded musician who can get along with effects without asking that the decision to have (what a good DSP)
- The first 4 (XLR), you also get the ability to assign a UAD plug preamp that will replace the card base and whose gain is adjustable with the knob (physical) of the latter.
- 2 in each with a plug.
- Routing options to the independent headphone monitor section.

The preamp, those cards themselves are downright good: good dynamic range and complies with the spectrum of the source. But it gets really interesting when we have (because they were purchased except 610) want to replace the plugs ... and it's heavy! 1073 is as expected, a gas plant! Very good to go ... I will summarize to: ANYTHING! 610 A and B they are more oriented voice and low for my taste. Brief happiness.

Now the little package that comes with the card: 670 Fairchild legacy, LA2A, 1176 Legacy, UAD610 B (and other less interesting).

The 1176 is quite faithful to its hardware version and give a big hit to your guitars, bass and with a battery (used Nuendo this time) it's a big bomb.

The LA-2A on a voice or bass will give you an excellent result (I do not know the hardware version), I have personally taken over full LA2A with their different characteristics of attack and release ... it's happiness.

Fairchild 670 and the Legacy ... what techies never dreamed of this machine? I sincerely doubt that a version software at $ 299 equals the Holy Grail of the compressor but it is meant little something the others do not. He is terrible on:

- Voice
- Skyscrapers
- Lower
- Battery
- Keyboards
- In the
- The master

Although the converters are just breathtaking, so I do not see the interest to dwell on it.

In short, it's 3am and I'm dead, so I leave you the pleasure of discovering it for yourself.

A manual .... ... why do ????


I use it for a month and I appercu possibilities ...

I had the EMU (my first), M-Audio, Presonus, SPL, RME, MOTU and Avid .... The only one that is made just as good in terms of conversion of the Madison SPL but with all DSP less. I speak of course of the map that I know ...

What I like most is all but non can connect 2 Duo Apollo cascade.

What I like least is not nothing but the ability to connect 2 Duo Apollo cascade.

With the new purchase, it is an investment but the quality both in its manufacture that is waiting for you when secondhand as I had ... not possible hesitations. Validate choice and I do it again and again.

Hopefully this review is helpful, I will post before the end of a video to compare different preamp for those who are interested.
