Based on a lighter specification of the UM17R, the UM17 is designed as an entry point into the world of high performance microphones for serious enthusiasts, and a reliable workhorse tool on a budget for professionals. Built with a focus on sound quality, there is only one major electronic difference between the UM17 and the UM17R, making it one of the highest spec'd and best value microphones in its class.

The UM17 uses the exact same circuit, NOS tube, and purpose-built AMI BV8 transformer as the UM17R. To meet a lower price-point, we only replaced the more expensive Thiersch capsule with a custom Asian-built K47/M7 hybrid. We modify and complete this capsule ourselves, ensuring that it's optimally tuned to the UM17 before it's assembled on the same chassis designed specifically for the R version. With sections made out of Plexiglas, it provides a painless platform to work on, for those who at some point would like to look into an aftermarket modification of the UM17's capsule. Out of the many choices available, both European and American, we highly recommend the Thiersch M7 as an upgrade, with the system specifically tuned to work optimally with either their Red or Blueline STW7.

For its components, the UM17 uses a Phillips 5840/EF732 sub-miniature NOS tube, AMI's custom all-nickel BV8LP transformer, and a Blackspade K17 capsule. The low-profile power supply is hand assembled in the US, providing the user with a remote control for 11 different polar patterns ranging from Omni to Figure 8. The entire system is covered by our 5 year limited warranty, with all units burnt-in and tested for 7-days prior to delivery.

With the low price-tag it's easy to underestimate the UM17's performance. To describe its sound, as a guideline only, it makes for a very versatile mid-forward microphone with a present but unimposing colour, and well balanced high-end. As with all our products, we highly recommend you contact your dealer for a demo in your own room, to experience it first hand.
