Preamps

The Millennia HV-37 is a 2-channel microphone preamp, with 70 dB gain, front panel instrument inputs and phantom power. The HV-37 gives you the unparalleled sound quality of two Millennia preamps in a single rack. Perfect for low-gain microphones, such as ribbons, the HV-37 delivers up to 70 dB gain without noise. The front panel instrument inputs also make the HV-37 fantastic for direct bass pickup. Other features, such as 80Hz high-pass filters and 15dB attenuation pads, add extra versatility to the HV-37, while an impressive frequency response of less than 3Hz to over 300kHz ensures that no nuance as subtle as it is, it does not get lost in the signal.
