Jensen Transformers SMMDB Overview

  • 1Description

The Iso-Max SMMDB from Jensen Transformers is a stereo direct box designed to drive unbalanced Hi-Z signals to distances up to 300' to a balanced mic level without high-frequency loss or introducing noise into the signal path. It can be used with stereo devices like laptops, MP3 players, CDs and DVD players.

The SMMDB comes standard with RCA and 3.5mm inputs and XLR outputs. Inside, two high-performance Jensen JT-DB-EPC transformers provide isolation and lower the impedance to perform the balancing. The transformers are effective at eliminating hum and buzz caused by ground loops. This is augmented with a ground-lift switch at the XLR output. A handy stereo-to-mono switch makes it easy to reduce the output channel count or send the same balanced signal to two destinations at once.

In addition, with over +22 dB of signal handling capacity at 20 Hz, the SMMDB handles extreme signals such as those produced by uncompressed audio files while producing a warm Bessel response that is pleasing to the ear. Plug and play with no power required, the SMMDB is the ideal choice for AV technicians that need a quick and simple solution.
