Introducing the Jensen Transformer option for ULN-2

Since its release in 2002, the ULN-2 has enjoyed a legendary reputation for its pristine, wire-like gain, and has established itself as one of the best values in the professional audio industry.

The ULN-2 possesses virtually every characteristic that is coveted in a Mic Preamp: exceptionally low noise at all gains, exceptionally high gain, excellent common mode and RFI rejection, incredibly flat frequency response, and ultra-low distortion. It simply increases the level of what you put into it without having to consider the nature of the source: Dynamic Mics, Phantom Powered Mics, Ribbon Mics, Instrument or line level signals are all handled with equal ease and quality.

So why change it?

The ULN-2 is an incredibly good Mic Pre, but sometimes you want something that isn’t quite "so pristine". It is well known that a certain amount of low-order harmonic distortion has a way of adding “depth” and “sheen” to everything — which explains the high regard for classic transformer coupled preamps.

Enter the Jensen Option

With the transformer option installed, the ULN-2 acquires that classic character. A few years ago, we fitted a prototype ULN-2 with a pair Jensen JT16-A's just for fun. We found that there were some very nice benefits to transformer coupling the input stage of the ULN-2. The Transformers impart a more "glossy", "smoothed" sound than the capacitively coupled ULN-2, which simply faithfully passes the source. Sonically, it's kind of like the difference between images shot on film and images shot in HD.

Enjoy complete isolation

A second benefit is that the transformer completely electrically isolates the preamp from the source – raising the common mode rejection above its already excellent performance, and providing a measure of confidence when dealing with the unknowns of location sound.

How to get it

The transformer option requires factory installation; we have to remove the cap coupling from your existing ULN-2 and carefully add the Jensen transformers to the signal path. When you order your upgrade, we will issue an RMA for you to send your unit into the Custom Shop and our technicians will install the option for you. Turn around time is typically 1 week from date of receipt of the unit.

If you simply want to order a new ULN-2 with the transformer option pre-installed at the factory, you can do that as well; this version of the ULN-2 is available directly from Metric Halo via Metric Halo Direct or from your dealer.

The transformer option is also available for the ULN-2+DSP.
