Palmer ABI - Balanced Line Input Switcher

The Palmer PEABI is more than a simple switcher for two sources, it also provides level adjustment of microphone or line signals. Whether microphone or line signal, the PEABI toggles silently between the two inputs permitting fast and simple signal comparison and the connection of two sources to one input. Three slide switches select 15 dB of attenuation for input A and 6, 15 or 21 dB for input B. A ground lift switch eliminates earth loop hum. The PEABI is housed in a solid metal case with extended edges for optimum protection of the inputs and output. A red LED clearly indicates which input is active.

Pre-drilled holes permit simple and secure mounting in a rack or on a pedalboard.

The PEABI's circuitry is all-passive. A 9 V block battery is required to power the LED.
