Tube-Tech HLT2A

The TUBE-TECH HLT 2A is a stereo equilizer featuring active low and high shelving EQ, a passive T-filter plus passive Hi/Lo cut filters and an overall bypass switch.

HLT 2A is an all-new kind of Equalizer featuring active low and high shelving EQ and a passive T-filter plus passive Hi/Lo cut filters. The shelving EQ's are designed around a high gain tube amplifier, and the T- filter and Hi/Lo filters are passive filters placed after the active shelving EQ and before the output amplifier. All sections are supplied with a bypass switch.
The HLT2A furthermore features an overall bypass switch.
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
  • TUBE-TECH HLT 2A is a stereo unit, featuring 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 T-filter is like a seesaw. When the low end goes up, the high end goes down and visa versa.
  • When the potentiometer is turned clockwise, the high frequencies are boosted and the low frequencies are attenuated.
  • When the potentiometer is turned counter clockwise, the low frequencies are boosted and the high frequencies are attenuated
  • 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.
