    • JENSEN JT-DB-E Direct Box Transformer

      JENSEN JT-DB-E Direct Box Transformer

      When loaded by the 1 kS input impedance typical of mic preamplifiers, this transformer has a 140 kS input impedance, making it ideal for high impedance sources. It can be used with or without an active buffer as a "direct box" for electric guitars or synthesizers. A 30 dB magnetic shield package is standard.

      • Converts unbalanced line levels to balanced mic level output
      • Stops "hum and buzz" problems in musical instrument hook-ups
      • Allows use of long cables without high frequency loss
      • High common-mode r

                        Jensen CI-2MINI Iso-Max PC Audio Ground Isolator

                        When used in unbalanced audio consumer interfaces, this isolator not only eliminates hum and buzz but also enhances audio quality by reducing "spectral contamination" due to ultrasonic and RF interference. To avoid excessive high frequency losses, no more than 3 feet of cable should be used on its outputs.

                        • Eliminates the inherent ground noise coupling mechanism
                        • Common-mode ground noise rejection of 95 dB at 60 Hz
                        • Wide bandwidth: !3 dB at 0.25 Hz and 50 kHz
                        • Handles signals up to 7 volts at 20 Hz or 1

                      • Jensen Transformers Concert-2 Two Channel Direct Box

                        Jensen Transformers Concert-2 Two Channel Direct Box

                        The Iso-Max Concert-2 is a stereo direct box designed to drive unbalanced instrument signals distances to 100 meters (300') or more without high frequency loss or introducing noise into the signal path.

                        The design begins with a rugged extruded aluminum enclosure and steel slide-in inner tray with recessed zones at each end to protect the switches and connectors. At one end, left and right ¬" instrument inputs and thru-puts are wired in parallel with a handy 3.5mm mini TRS for laptops and tablets.

                            Jensen Transformer DIN-AMP Active 1x4 Audio Distribution Amplifier

                            The Jensen Iso-Max DIN-AMP is a high performance distribution amplifier ideally suited for the AV systems contractor to easily integrate into a 19” rack or Nema enclosure by mounting it onto a standard DIN rail. Connections to and from the DIN-AMP is done via screw-down plug-in terminal eliminating the need for costly connectors.

                            The unique design features the patented InGenius input stage – an active drive circuit that replicates the noise rejection of a transformer, while providing upwards to 2
