Fast and Beefy, Times Four The four-channel rackmount version of Black Lion Audio's ever-popular Auteur MK2 preamp, the AuteurQuad combines an ultra-high-speed front end and a transformer-coupled output stage. The combination, which we've seen from Black Lion before, delivers lots of nuance and detail, nicely balanced with a beefy, vintage-flavored assertiveness that holds its own in a mix. The AuteurQuad has 65dB of gain on tap, so you can feel free to use your favorite ribbon mics on quieter sources. A DI input is provided on channels one and two for direct injection of electric guitars, bass, keyboards, and the like. Per-channel pads, polarity reverse, and phantom power complete the feature set. At GearNuts, we like the Black Lion AuteurQuad a lot. It's versatile and sounds great. Stack your rack with a few of them for outstanding multi-channel value!Excellent value in a four-channel preamp Since 2006, Black Lion Audio has
