SUMMIT AUDIO / TD-100

This preamp/DI delivers the warm, fat sound you expect from a vacuum tube. It features a loading control that adjusts input impedance, allowing you to perfectly match it to your instrument. Immerse yourself in the rich, rich tone that can only be achieved with the TD100. It's also famously used by Seiji Kameda, bassist for Tokyo Incidents.

[Front Direct Out]
The signal input to the INPUT is output unchanged.
[Ground Lift]
This can sometimes reduce noise caused by ground loops.
[Loading]
Use this to adjust the impedance of the INPUT signal between 10kΩ and 2MΩ, matching the impedance of your instrument to the TD100. Use it as a kind of tone control to achieve your desired sound.
[Headphone Out]
Volume is controlled by the OUTPUT GAIN and the instrument's volume control.
[TRS Phone Line Level Output]
Use when connecting to recording equipment without a preamp.
[XLR Mic Level Output]
Use when connecting to equipment with a preamp, such as a mixer.

Quick Start
1. Connect your instrument to the INPUT.
2. Connect your recording equipment to the TRS phone or XLR output on the rear panel.
3. Adjust the OUTPUT gain to the optimum level.
4. Adjust the LOADING knob on the front panel for the best sound.
5. Then, just play!
