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.
Technical:
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.
So how does it sound?
The TUBE-TECH HLT 2A marks a different approach to EQ'ing. It is a very powerful overall shaping EQ, yet extremely simple to operate.
To put it simply, the HLT2A will yield good results for basically any material and application, ranging from the demanding mastering engineer to the sound quality hungry project studio owner.
The combination of Hi and Lo shelf and Lo/Mid frequency T just creates a ton of very nice EQ shaping possibilities!
