A/B selector & attenuator

The 2xA/B module is a passive utility grouping two independent “A/B selectors”, it is an alternative version of the A/B selector, attenuator & multiple

This is a utility grouping together two identical independent stages:

An A/B switch with output attenuators and a selector with central “off” position.
A normalization allows the signal connected to “IN PART I” to be routed internally to the lower part, as a pre-attenuator. This allows you to have multiple combinations. Connecting a cable to the lower “IN II” breaks this link, making the two floors independent.

All signals are accepted.

Available with black panel.
