    • Henry Engineering Matchbox HD Bi-Directional Stereo Level & Impedance Interface

      Henry Engineering Matchbox HD Bi-Directional Stereo Level & Impedance Interface

      The rack-mountable Matchbox HD is the new high performance version of the industry's most popular analog level and impedance converter. Matchbox HD offers a true 100 dB S/N ratio, with 22 dB of headroom to yield 122 dB of dynamic range. It is the very best way to interface "consumer" or semi-pro equipment with professional audio gear.

      The Matchbox HD is a bi-directional unit, employing four independent amplifiers to convert stereo inputs and outputs from unbalanced -10 dBv levels to +4 dBm balanc

                                The T8T (Transformer Eight) a high quality totally passive audio interface that uses 8 transformers to separate input and output signal grounds, thereby isolating two systems and reducing hum and ground-loop noise. The T8's audio transformers have flat and wide frequency response and handle high signal levels while maintaining an isolated balanced output. This gives the T8 a very clean and neutral sound with a wide variety of signal sources. The transformers are wound for 1:1 unity gain and are

                                      Audio Level & Impedance Matching Transformers create compatible signals between microphones, line-level devices, laptops, digital 75 ohm and 110 ohm AES/EBU devices. For example, Audio Level Matchers allow you to connect a professional studio microphone to a computer or other "consumer" style recording device. In addition, Audio Level Matchers allow the connection of consumer CD players, tape decks or other devices to the XLR inputs of a Professional mixing console. Every Audio Engineer and Technician should have a variety in their toolbox to ensure the show goes on! Speak with a Markertek representative today and ensure you choose the Audio Level Matcher that best suits your application.
