APPLICATION For matching high impedance (10k ohm) guitar pick-up etc to microphone input. Ensures optimum loading of the guitar pick-up and correct matching to microphone pre-amplifier. For use in high electrical noise environments such as when pick-up is connected to guitar amplifier as well as microphone channel. Accepts balanced or unbalanced inputs or outputs. Ideal for matching a high impedance amplifier output to a balanced 600 ohm line but a dc blocking capacitor must be used.
FEATURES Mumetal core for minimal harmonic distortion. Two separate Faraday (electrostatic) screens for rejecting noise in both guitar amplifier and microphone channel. Mumetal can for magnetic shielding.
