LaChapell 500TDI – Tube DI for 500 Series!

The LaChapell 500TDI is a 500 series tube direct box (tube DI) that ranges from pristine clean to loads of character. It can be focused and articulate with crisp distinguished notes, or meaty with a growl and harmonic overtones. Using the tube-drive and level knobs, dial in the perfect tone for your bass or other instruments.

The 500TDI Tube DI features LaChapell Audio’s TrueTube™ technology which provides a proper operating voltage to the 12DW7 tube. Most tube modules for the 500 series use a starved plate design which does not give the tube the full voltage it needs to get the tube sound recognized as “classic tube tone.” A Cinemag transformer adds some weight and warmth to the output.

The front panel of the 500TDI tube direct box has two inputs. The top input is a high impedance input while the bottom input can be used as a through OR a lower impedance input for more tone options.
