Millennia HV-37 Two-Channel Microphone Preamp Details

The Millennia HV-37 Two-Channel Microphone Preamp, along with the 500-series HV-35 is one of the newest preamps to the Millennia line. The simplest way to describe it is to say that it is a pair of the HV-35 preamps mounted together in their own single rack-space chassis and dedicated power supply. This makes the HV-37 a perfect way for the cost-conscious to achieve Millennia-quality performance in a package that won't break the bank.

And like the HV-35, the HV-37 has the Ribbon Mic DC feature which is normally available only as an option on the more expensive HV-3C and HV-3D preamps. Ribbon Mic DC couples the mic to the gain stage and also provides an additional 10dB of gain. Use with any Ribbon or Dynamic mic (like an SM-57). A mic requiring phantom power will not work in this mode. The HPF (High Pass Filter) rolls off low frequencies below 80 Hz at 3 dB per octave. It also features a Hi-Z Inst Input (Instrument Input) that is for high impedance sources such as bass guitars.

Unlike the HV-3C and HV-3D models, the Gain knob on the HV-37 is a continuously variable gain control. It has a high gain jump near full clockwise for low level signals.

What We Think

The Millennia HV-37 Two-Channel Microphone Preamp is a fantastic addition to any studio or recording setup looking to improve the recorded signal to the quality that Millennia is known for, while also not breaking the bank. Compare the specs of their acclaimed and award winning industry-standard HV-3C and HV-3D series preamps, and the HV-37... you'll see that the performance translates in regards to frequency response, phase, slew rate, common mode rejection, etc. The HV-3C and HV-3D do offer some improvements in maximum gain (+5dB), noise (an additional -3dB down), max. input level, and max. output level. And that's sort of expected given that the HV-3C and HV-3D are not bound to the power-current restrictions of the 500-Series - for which the HV-35 was designed (the HV-37 was adapted from the HV-35 500-series module). But aside from some of the differences in "feel" of the knobs, mega-thick faceplate of the HV-3C and HV-3D, the HV-37 will provide some seriously great sound. And let's not forget the price - for the same price as a pair of HV-35 modules, you can have 2 channels of the exact same circuit in a single 19-inch rack unit. Basically, Millennia is tossing in their own power supply free of charge. The Millennia Media HV-37 is not a bad deal in any way shape or form. We highly recommend benefiting from having one or two of these units in your studio.
