Signal Processing
The equalizer controls are 4 band parametric. The top and bottom band can be made into shelf response equalizers or peak response equalizers. The midrange level control, when taken all the way down, becomes a notch filter to completely eliminate a particular frequency; turning thge level control of the high-frequency or low-frequency bands makes the band a cut-off filter.  The display window will show a frequency response graph of the equalization applied to aid the operator setting the EQ.
The TM-D8000  has a built-in dynamics processing function with eight "assignable" dynamics processors. The dynamics processing can be compression, limiting, gating or expansion. The console functions of gating and compression use separate controls and can both be applied to a channel.
Libraries
Library functions on the TM-D8000 store 99 parameter settings. Libraries are available for equalization settings, dynamics processing settings and snapshots (a storage of all parameters). There is also a library function for routing that has 10 memory locations. You can recall any of the stock settings, modify several parameters and store it under a different name.
Other Features
The TM-D8000 can reverse the phase (polarity) of any input.  The TM-D8000 can attenuate the signal after it is converted to digital. There is an attenuator function that is applied after the signal becomes digital so that if the boosting of certain frequencies with EQ causes overload, the signal can be brought down.
There is a channel delay function on each TM-D8000 channel of up to 185 ms in one-sample increments (1/44,100th of a second at 44.1 K sampling rate). Delay is an important function and is needed to compensate for signals that go though more digital devices than other signals. 
Channels can be made into stereo pairs and can also be grouped so that movement of one fader effects several others. The faders at the bottom right of the console are "group" controls that will change the level of any fader assigned to the group [GO HERE FOR ILLUSTRATION].
There is a solo function in the TM-D8000. The solo can be made "pre-fader-listen" where the channel is heard in the monitors with reverb and panning and without interrupting the recording (commonly called a "Recording Solo").  The solo can also be used as an in-place solo that will mute other channels and allow the single channel to be heard with panning and reverb (commonly called a "Mixing Solo").
