The ATT100 is intended to interface a 100V line speaker system to a high impedance balanced line input such as those found on Ampetronic preamplifiers and induction loop amplifiers. The unit provides a balanced resistive attenuation of -40dB.
The standard version of the ATT100 is not suitable for use with unbalanced or low impedance inputs, nor should it be connected to microphone inputs of any type.
