                                              The STP-1 is a pair of convenient attenuator pads that can be located at the precise location that attenuation is needed. The low-cost STP-1 eliminates the costly labor of figuring and assembling fixed pads. Multi-turn trimmers in the STP-1 permit precise adjustment of levels without the need to connect any jumpers or external resistors. The STP-1 operates in either high or low impedance, balanced or unbalanced circuits. The wiring legend is printed on the case for easy installation.

                                              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.
