Tube-Tech HLT 2A

The TUBE-TECH HLT 2A is an all-new kind of Equalizer, combining High and Low shelving Eq plus Hi and Low cut filters with an innovative T filter “tilt” midrange Eq. It’s the first time this combination of filters has been designed in the analog domain.

• Tube based push-pull amplifier
• Freq. resp. @ -3 dB: 5 Hz – 55 kHz
• Low noise: < -80 dBU @ 0 dB gain
• CMRR: > 60 dB @ 10 kHz
• All-tube active/passive EQ
• FILTERS:
• Low cut: 18, 25, 40, 60, 85 Hz, 6db/octave
• Low shelving: 18, 37, 80, 180, 370, 800 Hz. Gain: +/‑12dB
• High shelving: 1, 2, 5, 10, 15, 22 kHz Gain: +/‑12dB
• T.-filter: 0,5, 1, 2kHz. Gain: +4/-7 dB
• High cut: 12, 15, 18, 20, 25 kHz, 6db/octave
• Tracking between channels: +/-0,3 dB
• Input impedance: >10 kΩ
• Output impedance: < 60Ω
• Conductive plastic potentiometers
• In- and output are transformer balanced and fully floating
