The HV-37 features a transformerless input, balanced audio path, and minimal amplifier design, offering the most transparent path from your microphone to the rest of your signal chain.

Your microphone preamp is the critical link in having clear, crisp audio with your personality incorporated, and the Millennia HV-37 is the perfect mic and instrument preamp to achieve your desired effect. The Millennia microphone preamps are a much loved favourite and the choice of guitar greats such as Joe Satriani, who says "the 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!" The convenient rackmount format features an on-board universal power supply, as well as 80Hz highpass filters and 15dB pads, with an impressive sub-3Hz to over-300kHz frequency response ensures that no nuances, however subtle, are lost in translation.
