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. | |||
