                                  The Digital To Analog Audio converter box takes your coaxial/optical (S/PDIF or TOSLink) digital audio source and converts it to standard analog left/right audio, available for connection to an external device such as an amplifier or recording deck via standard RCA-style jacks. Now you can bridge your legacy sound system with digital sources such as DVD and CD players that don't have RCA-style analog outputs.

                                      Impedance Matching Transformers create compatible signals between microphones, line-level devices, laptops, digital 75 ohm and 110 ohm AES/EBU devices. For example, Impedance Matching Transformers allow you to connect a professional studio microphone to a computer or other "consumer" style recording device. In addition, Impedance Matching Transformers 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 of Impedance Matching Transformers in their toolbox to ensure the show goes on! Speak with a Markertek representative today and ensure you choose the Matching Transformer that best suits your application.
