Millennia 500 Series HV-35 Single Channel Microphone Preamplifier Module

Static electricity can harm delicate components on the HV-35 board. To prevent static damage, discharge static electricity from your body before you touch any jumpers or switches with the cover removed. You can do so by touching an unpainted metal surface on the API rack's chassis.• Continuously variable gain control• Front panel instrument input• DC coupled ribbon mic with 10dB gain boost setting• 80Hz roll off filter• 48V phantom power• 15dB Pad• Polarity flip• API 500 series compatible format Compatible Racks The HV-35 is designed to work in an API 500VPR or Lunch box rack. If you are using another brand, be sure it meets or exceeds the API spec. The HV-35 power consumption is +45mA, -25mA nominal, +75mA, -25mA with +48V selected. Signal Present (green) and Peak (red) LEDs Indicate signal present at -46dB and peaks at +22dB. Pad Attenuates the input signal after the gain stage by 13.5dB. Pol Flip (Polarity Flip) Inverts the signal's polarity. This can be useful in multiple mic setups to change the interaction between them. +48V Turns the phantom power supply on. 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. HPF (High Pass Filter) Rolls off low frequencies below 80Hz at 6dB per octave. Instrument Input Instrument Input is for high impedance sources such as bass guitars. It makes the Hi-Z Instrument input active. Gain Gain is a continuously variable gain control. It has a high gain jump near full clockwise for low level signals.
