Symetrix 581E

The Symetrix 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 balanced input stages are designed for high common mode rejection and RF immunity. Output line drivers are stable short-circuit protected and designed around industry standard 5532 type op amps. 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.The 4x4 architecture of the 581E allows the amplifier to fit the greatest possible number of configurations. Each one input, four output module is independent of the others. Wiring the 581Eís inputs to four separate audio sources provides four mono distribution channels with four outputs each. This configuration also accommodates two stereo audio feeds.An alternate 2x8 configuration of the 581E is possible through simple rewiring. Stereo audio can be distributed to eight outputs by strapping the inputs together in pairs. Left channel audio is wired to inputs #1 and #2, while the right channel connects to inputs #3 and #4. The 581E distributes a single mono audio source to all 16 outputs when all inputs are strapped together. Regardless of your audio distribution requirements, the Symetrix 581E solves the problem with minimum cost and no wasted outputs.
