(Transformerless Box of Directness)

Active Noise Optimizing Direct Box, Re-amp Box and Signal Splitter

The TBD is a multifunctional studio interface device. It can perform several commonly required tasks such as single-ended to differential conversion, direct injection or DI Box, signal splitting, buffering, gain control, impedance matching and “re-amping”.

The TDB is designed with no input or output transformers in order to minimize hum pick-up, maintain flat frequency response and provide flexible impedances and loading capabilities.

It is designed to be audibly superior, dead quiet, flexible and of course to possess the legendary reliability for which Holland Synthesizer equipment is known.
