The Millenia HV-37 is a two channel microphone and instrument preamplifier. Authentic Transparency for Unrestricted Creativity
Barry Rudolph - Music Connection
"In all comparisons the HV-37 was truer to the source with better definition in the bass and it had a significantly more open top end."
Hugh Robjohns - Sound on Sound
"The HV37's performance is, by any definition, impressive and sublime...
A good friend uses an eight-channel HV3D for a lot of his location recording work and I have often coveted the fast, detailed and silky, but fundamentally uncoloured and transparent, sound it captures. The HV37 shares that character exactly and impeccably. I was very hard-pressed to spot any significant difference between them."
Joe Satriani - Guitar
"I have used the STT-1 for home and pro-studio recording for years now, and it has always been my favorite mic-pre/recording system. Now, the more streamlined HV-37 has made my DI electric guitar and bass recordings even more transparent and accurate. The headroom is wonderful, and the ease of use fantastic. I love it!"
Rich Tozzoli - Pro Audio Review
"The HV-37 delivers on all the adjectives you might expect to hear; it's clean, pure, invisible and musical."
Brandon T. Hickey - MIX Magazine
"The ability to capture reality now and flavor it to taste another day is a commodity that is easy to appreciate, and the HV-37 provides the perfect go-to preamp to achieve that goal."
Paul Vnuck - Recording Magazine
"Bottom line, the HV-37 always sounds good and captures every source clearly, but somehow not boringly. You may have heard of the Millennia sheen... it's there for sure. I can't describe it, but, man, do I love it!"
