HLT2A Shelving EQ with T-Filter HLT2A Shelving EQ with T-Filter

 

A totally new kind of analog equalizer that combines variable high and low shelving eq and filters with an adjustable midrange T-Filter. The midrange T-Filter "tilts" the entire spectrum around a selectable midrange frequency point. Frequencies above that point increase (or decrease) while frequencies below that point decrease (or increase). This unique topology provides a powerful and uniquely efficient way to get beautiful-sounding overall equalization. As such, the Tube-Tech HLT-2A is destined to become a "go-to" equalizer in high-end mastering houses,smaller project studios, and everything in between.

Like all Tube-Tech processors, the stereo HLT-2A possesses a warmth and character that breathes life into a track and gives it an organic body that somehow manages to occupy real physical space inside a stereo mix, However, the functionality of the HLT-2A is unique in the Tube-Tech line - and indeed in the world of analog processing. Users will find that the HLT-2A generates quick, intuitive results that can range from mild to extreme, and it sounds great on individual tracks or strapped across the drum bus or the mix bus.

Features

  • Low and high cut filters, low and high shelving filters, and a T-filter
  • The shelving filters are designed around a high gain tube amplifier
  • The T-filter is a passive filter placed between the shelving filters and the output amplifier
  • All three sections are supplied with a in / out switch
  • The low and high cut filters are also passive with a slope of 6dB / octave
  • A bypass switches the whole filter section out of the amplifier circuit, keeping the output stage in the circuit
  • The unit is all tube based except for the power supply
  • Input and output have fully floating transformers
  • All DC voltages are stabilized, except the anode voltage for the output stage
