In essence is merely a volume control designed to attenuate the signal going from the source to the amplifier. Since it is passive, it has no inherent gain because it has no active components (tubes or transistors) in the signal path.
Without colouration, noise or distortion, but has unrivalled transparency enabling you to enjoy the original recording to the full.
