The 581E Distribution Amplifier (4x4) is a four-input, sixteen-output distribution amplifier.

In a typical configuration the 581E accepts four input signals and distributes each input to four independent outputs. The attenuation of each of the sixteen outputs may be individually trimmed via its front panel potentiometer. Similarly, the level of each of the four inputs may be independently controlled. Associated with each input is a four LED level meter to assist the user in setting optimum operating levels. The 581E operates from an internal power supply built around a low magnetic field toroidal transformer, resulting in a very low noise, high performance product.
