T1 ToneMatch® Audio Engine: Difference between revisions

There is also some fairly unique processing such as kick-gate (for drums), zEQ and ~~ToneMatch~~, that is not available from any other device I'm aware of.

... (the preamps on the Model I are)... exactly the same as the Classic.

On the {{T1}} they're different, but are designed to the same standard as the {{Classic}} preamps.

Functionally they are basically the same in terms of frequency response, input impedance, noise performance, max gains etc.

The difference comes in how we get there. I'll try not to go into horribly boring detail. The name of the game is trade offs, and in the end the design constraints dictate the *best* type of circuit used for *this* particular situation. Here are a couple of the many factors that dictate the differences:

Gain structure. The internal components of the {{T1}} are different that the {{Model I}} / {{Classic}} and need to have signals fed to them in certain ways. Different designs are more suited to the levels needed than others.

Physical layout of the circuit on the board. There are four channels in a tighter space in the {{T1}}. Again, certain designs lend themselves to be better at this than others.

After evaluating all of the factors that go into the design of a preamp we are using another proven circuit that relies more on discrete transistors rather than op-amps. It fits our needs better for this design situation. The preamp design itself is not necessarily any better or worse. There are *many* ways to skin the cat of preamp design to achieve a desired performance.

Will it sound different? No...I certainly cannot hear a difference playing through it. Can't measure one either.

Hope this sheds some light on it.
