Isoplus
AV audio isolating transformer Features RCA, XLR and JACK inputs and outputs, Earth Lift and a 20dB Pad. This is a broadcast quality line isolator / hum eliminator which can be used to balance an unbalanced line, such as the output of a VCR, to preserve fidelity over a long cable run to the balanced input of a mixing desk, or to unbalance a balanced line, presenting a balanced input to a microphone or other signal, whilst outputting to an unbalanced input on a mixing desk or other device. Devices with dissimilar input / output connectors can be accommodated via the unusual configuration of XLR, Jack and RCA in and out. The 20dB pad can be used to connect high level devices such as computer headphone or betacam recorder outputs to low level input devices. Can be used as a 600ohm bridging transformer, where the input signal passes "through" the input side via the bridged XLR and JACK connectors to the input of a mixing desk, and an isolated split is taken via any of the outputs. Using the 20dB pad in this configuration will only affect the isolated output, and will not affect the "through" output
