About Millennia HV-35

Become a master of sound with the 500 Series HV-35 Single Channel Microphone Preamplifier Module, a high-quality, professional-grade audio equipment from the reputable brand, Millennia. This versatile and durable module is designed to enhance the sound quality of a single microphone, making it an essential tool for any audio professional.

The HV-35 is equipped with a solid-state design, known for its reliability and durability compared to tube-based designs. It boasts a low noise floor, enabling it to capture even the quietest sounds, making it ideal for a variety of audio recording scenarios.

This single channel microphone preamplifier module is designed to work seamlessly in a 500 series rack system. It amplifies the signal from a microphone before it is sent to a mixing console or other audio equipment, ensuring optimal sound quality.

The HV-35 features a continuously variable gain control and a front panel instrument input. It also comes with a DC coupled ribbon mic with a 10dB gain boost setting, an 80Hz roll-off filter, and 48V phantom power. It also includes a 15dB Pad and a polarity flip feature, making it a versatile addition to your audio equipment collection.

The HV-35 is compatible with API 500 series format and is designed to work in an API 500VPR or Lunch box rack. It comes with Signal Present (green) and Peak (red) LEDs that indicate signal present at -46dB and peaks at +22dB. The pad feature attenuates the input signal after the gain stage by 13.5dB, while the Pol Flip (Polarity Flip) inverts the signal's polarity, which can be useful in multiple mic setups to change the interaction between them.

The HV-35 also features a Ribbon Mic DC that couples the mic to the gain stage and provides an additional 10dB of gain. It also includes a HPF (High Pass Filter) that rolls off low frequencies below 80Hz at 6dB per octave and an Instrument Input for high impedance sources such as bass guitars.

With the 500 Series HV-35 Single Channel Microphone Preamplifier Module, you can ensure high-quality, professional-grade sound in every recording.
