Input Processor (P.I.P.)

P.I.P.-ISO is designed especially for 25 to 140 volt dis- tributed systems where UL®-listed isolation is required. Installation requires minor amplifier modifications. With the P.I.P.-ISO installed, the amplifier outputs are safely isolated from the input terminals and the chassis.

P.I.P.-XOV is a versatile 18 dB/octave mono crossover/ filter with biamping and triamping capabilities.

P.I.P.-FMX facilitates “daisy-chaining” balanced ampli- fier inputs. Female to male three-pin XLR connectors are used to passively bridge the inputs.

P.I.P.-FXQ makes it easy to connect audio sources that have phono (RCA) connectors. It includes two balanced three-pin female XLR connectors, and two female phono jacks for quasi-balanced or unbalanced operation.

P.I.P.-102 is a two-channel module providing equaliza- tion based on the BOSE® 102 controller. Screw terminal plugs provide balanced connections. Each input chan- nel has an output from the P.I.P. that can be indepen- dently configured for output with no processing, 102 equalization or 102 equalization with bass-cut.

P.I.P.-RPA adds the features of a 4x2 mixer to your am- plifier. Its four inputs accept mic- or line-level input. It offers priority switching (“voice-over”) of each input and remote level control with the RPA-RMT. Other features include bus inputs and outputs, adjustable input sensi- tivity, phantom power and RFI suppression. Input isola- tion transformers are optional.
