Abverkauf Tube-Tech HLT 2AM – Stereo EQ und T-Filter, Mastering-Version

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.
