The TUBE-TECH HLT 2A is an all-new kind of EQ, combining Hi and Lo shelving with a midrange T- control, that bends the whole frequency spectrum up or down around a selectable midrange frequency.

(It's is the first time this combination of filters has been designed in the analogue domain.)

Technical:
HLT 2A is a stereo unit, featuring low and high shelving filters and a T - control bend filter. The shelving filters are designed around a high gain tube amplifier, and the T- filter is a passive filter placed after the shelving filters and the output amplifier. All three sections are supplied with a bypass switch. In addition to these controls the HLT 2A features Hi and Lo filters + an overall bypass switch.

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!
