"The sound of the Tube-Tech HLT 2A is sensational! True enough, Eddie Van Halen nailed it when he said, ‘You can’t polish shit’, but any source with the slightest whiff of quality will sound better than before when processed through this machine…What I’ve accomplished here with two or three dB’s change, leaves me in grave doubt about the EQ’s that used to be my favorites…Whether or not I need the TUBE-TECH HLT 2A is no longer a question, because the sound is simply grandiose. The only issue is the necessary petty cash. So, off to the bank…”
Resolution Magazine Review
The HLT2A delivers what it promises in a smooth, coherent and unfussy manner. Other tools are available for fussing and fiddeling. This is a Rolls Royce of EQ's: an elegant solution for smoothly tilting things to suit the context and I'd love to have this in my recording chain all the time"
HLT2A - A New TUBE-TECH EQ! It's here Now!
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!
Mastering Version Later in 2015 John G Petersen will do a mastering version of the HLT2A with stepped pots and a smaller and more detailed range for the shelf and T- filter eq.
