                                    RDL STP-1 Universal Audio Attenuator - 2 Channel

                                    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.

                                    Hosa ATT-448 XLR Female to XLR Male 20/30/40dB Mic Attenuator

                                    This switchable input attenuator is great for stepping-down input level to a mixer when the level is too hight. Maybe you've got a hot microphone in front of a loud source, and you're "pegging the meters" at the board. Just insert the ATT-448 attenuator in the line between the mic and the board, and switch in the appropriate amount of attenuation to match the level the board wants to see. You can choose 20, 30, or 40dB of signal reduction, for a wide range of uses on stage and in the studio.

                                    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.
