The Manley TNT 2-Channel Preamp combines tubes and transformers and solid-state circuity, making for two distinctly different channels.
The left channel of the TNT (Tubes – Not Tubes) uses both tubes and transformers from Manley’s popular ‘SLAM!’ mic pre, whilst the right has been inspired by old British console preamps with a tasty combination of "No Tubes" design with transformers. Both have been designed to make your life a whole lot easier, meaning you can just plug a mic in and it sounds great.
The tube channel excels on traditionally difficult sources like some bright guitars, reed and brass, cymbals and some vocals. The "No Tubes" channel might be more suited for smoother vocals, drums, bass and raunchy guitars, but you never really know which preamp is best for the job at hand until you try them. At least you'll have two qualified candidates in one handy 1U chassis.
The people over at Manley Labs reached out to their audience and asked for suggestions that they’d like to see on the TNT. The number one request they received was about variable input impedance. Manley decided to offer variable impedance done right, with typically near-zero gain changes. In fact, on the solid-state side a current-mode preamp is used for the lowest impedance and a voltage mode preamp is used for the highest impedances, and these two preamps are appropriately blended for the medium impedance settings. This means that the entire microphone signal is used and almost none thrown away. A 3-way impedance switch has been added to the tube side that also compensates for the typical gain changes.
The MANLEY TNT is a remarkable and desirable tube preamp on one side and its equivalent in solid-state on the other side. These are not simulations, not samples, nor are they a clone or a toy. It is really good ol' analog done right.
