    • Jensen VRD-1FF IsoMax Digital RF Isolator

      Jensen VRD-1FF IsoMax Digital RF Isolator

      The IsoMax VRD-1FF is a high performance capacitive based isolator that has been meticulously designed to break the ground loop that causes hum and buzz in audio and 60 cycle hum bars in video.

      Housed in a compact cylinder and designed for use with RG59 or RG6 type cable, this second generation VRD-1FF employs a unique RF engineered solution that delivers a ruler-flat response from 2 Mhz to over 1300 MHz spanning the VHF/FM/UHF and CATV spectrum. The VRD-1FF's exceptionally linear response preven

      • Jensen VBH-5BB Component Video & VGA Hum Eliminator Ground Loop Isolator

        Jensen VBH-5BB Component Video & VGA Hum Eliminator Ground Loop Isolator

        The ISO-MAX VBH-5BB reduces ground current induced video interference such as "hum bars" by a factor of over 100, eliminating the visible effects of these types of interference. The high bandwidth and low VSWR prevent degradation of the picture quality due to high frequency roll-off and cable reflections.

        When used with a D15HDM-5BF-3 VGA breakout cable, this is a great solution to eliminate hum from any VGA system.

        • Provides 56dB Reduction in Ground Loops
        • DC to 600MHz (VBH-3RR) or 900MHz Bandwidth

                          • Jensen DIN-LO-11FL 600 to 600 1:1 Line Output Module

                            Jensen DIN-LO-11FL 600 to 600 1:1 Line Output Module

                            +21dBu Level Handling, 0.035% THD

                            This module is designed for high performance line output stages. The 50% nickel alloy core gives it excellent distortion and level handling at a cost allowing many applications to enjoy the advantages of an output transformer. Driving signals should be free of DC and source impedance kept as low as possible.

                            • Distortion 0.035% typ at 20 Hz and +4 dBu output level
                            • Wide bandwidth: !3 dB at 0.2 Hz and 15 MHz
                            • Drives 600 S loads to levels up to +21 dBu at 20 Hz
                            • Excellent t

                                  Jensen Transformers DIN-DB 12:1 Direct Box

                                  When loaded by the 1.5 k Ohm input impedance typical of mic preamps, this module has a 200 kS input impedance, making it ideal for high impedance sources. It can be used with or without the input and output attenuator pads to accommodate a wide range of signal levels. A 30 dB magnetic shield package is standard.

                                  • Converts line levels to balanced mic level output
                                    Stops "hum and buzz" problems in musical instrument hook-ups
