Cambridge EQ in Sound Forge 6.0 (Click image for larger view)
Cambridge is a strong EQ, one that promises to deliver consistent good results. Its sound is clean, and it has a 20Hz-20kHz dynamic range (good for maximizing signal to noise ratio). The controls are precise and accurate, and the GUI is straightforward (for you trivia fans, the knob graphics are based on the original Universal Audio 565 "Little Dipper" EQ). The parameters are very adjustable, and offer, among other things, sweepable capabilities.

Unfortunately, as Cambridge was not yet released at the time of this review, I used it in the five-minute demo mode, so I could not fully explore its parameters (no saving of presets, only one instance per song in demo mode). But I heard enough to know that it’s an impressive professional tool, certainly worth buying if you own this card. According to Universal Audio, the full version of Cambridge will supply about 12 stereo or 24 mono instances per card at 48kHz with all filters and bands turned on. With those turned off, the count goes up.[an error occurred while processing this directive]

Compared to the Sony Oxford, another new digital EQ being released on the competing PowerCore platform, the Cambridge has been described as somewhat brighter. In one engineer’s assessment, think Neve EQ for Cambridge, Trident EQ for the Oxford. Many participants on Chris Milne’s excellent independent UAD-1 forum agree that the two EQs complement each other well, and in fact, for a full sonic palette, some users are installing both UAD-1 cards and PowerCore cards in their machines to have different options.

Installation
I tested the UAD-1 on a dual-Athlon 2000+ PC with 1GB RAM and an ASUS motherboard running Windows 2000, using Cubase SX, SONAR 2.2 and Sound Forge 6 as host applications. Installing the UAD-1 card is fairly straightforward. There are only a couple of standard gotchas, so you just need to pay attention.

One is a dialog box that asks you whether you want to install both VST plug-ins and Direct X plug-ins. VST is highlighted as the default, but if you intend to use SONAR, Sound Forge, Cool Edit Pro or Samplitude (see chart at right for complete application list) as a host, you need to select Direct X. I selected both the Direct X and VST options, so I could use the card with Direct X applications SONAR and Sound Forge as well as with Cubase SX, a VST application. This worked fine for me with SONAR 2.2, using its newly added ASIO support and the latest ASIO drivers for my M-Audio Delta 1010 audio interface. I didn’t try Sound Forge until installing the Version 3.01 upgrade, but Sound Forge was also able to run the plug-ins without a hitch. Apparently, 3.0.1 fixed some Direct X bugs experienced by some users, but I didn’t encounter them. And Cubase, running the card’s native VST host, performed flawlessly with the UAD-1.

With SONAR under Version 3.0, I wasn't able to use the WDM drivers for the computer's M-Audio Delta 1010 audio interface. As soon as I started playback with the WDM drivers, a dropout occurred and SONAR stopped. Fortunately, the new SONAR 2.2 update includes support for ASIO drivers. When I switched to the latest Delta 1010 ASIO drivers, the card worked fine with SONAR and the UAD-1's Version 3.0.1 update.

I upgraded the operating software twice during the course of this review, from 2.3 to 3.0 and then to 3.0.1. The first time, the new drivers wouldn’t take until I deleted the old ones, removed the card, installed Version 3.0 and then replaced the card. This procedure is suggested for balky installations in the UAD-1 manual. But installing Version 3.0.1 was a breeze -- I downloaded the file, extracted it, clicked the options, restarted and was good to go.
