In the world of pro audio, it seems there are endless ways to manipulate your signals. However, the Copperline from Locomotive Audio does something we’ve never seen before. The new device from the boutique audio maker from Saint Louis, Missouri, supplies a variable amount of phantom power to your condenser mics.

According to Eric Strouth, the man behind the brand, this can create some unusual effects. For example, it can bring up the noise floor, reduce headroom, change the transient response, frequency response and more. All this means that you can get new characters out of your existing mics.

The Copperline is slated for release in the autumn for a price around $750. More information at
