    • 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

                                        ART PDB4 Four Channel Passive Direct Box - 1RU

                                        The ART PDB4 Four Channel Passive Direct Box is a deceptively simple, yet surprisingly useful addition to any serious collection of
                                        audio equipment. The PDB4 is a four channel passive direct box that features four quality, fully transformer isolated, direct boxes in a 1U 19-inch rack mount chassis.

                                        Inputs and outputs of each of the four channels are isolated to maximize channel separation. Transformer isolation on each output helps to eliminate system ground loops.

                                          Introducing the new DB24 Stereo Direct Interface. This unit is a two channel isolation device designed to connect high impedance devices to low impedance. The unit is completely passive, and utilizes Rolls proprietary audio transformers for superior sound. A heavy duty steel chassis was chosen to provide maximum reliability when used in demanding live sound reinforcement applications.

                                          A variety of inputs are provided including stereo and mono 1/4", stereo RCA, and stereo 1/8" (3.5mm).

It combines the output from two microphones into one channel. A continuously variable balance control allows the two input sources to be mixed. Applications for the UniMix include expanding the input capacity of mixers, combining two microphones to send signal down a single cable where it is difficult to run a second cable, and combining microphones on similar instruments to minimize

                                              The DUALXDirect provides two independent high quality active interfaces that let you connect instrument, line, or speaker level signals to a mixer or other balanced inputs. Each of the high impedance 1/4" and XLR inputs (provided via "combo" jacks) are buffered and converted by very low noise active electronics into an isolated, balanced, low impedance signal output. The DUALXDirect has an extremely flat and wide frequency response and can handle high signal levels. This gives the DUALXDirect a
