DF1 Digital Fader

The Pennywise DF1 Digital Fader enables serial control of sound processors which do not have their own serial interfaces. The DF1 has been designed especially for use with the newer CAPIO version of the cinema automation unit. The CAPIO version does not have digital fader control.

The features of the DF1 are

an RS-232 serial interface for connecting to the automation

relays for controlling the sound processor (selecting sound formats, mute, remote fader)

optically isolated inputs for receiving status information from the sound processor (sensing the sound format status leds, mute led, fader remote led)

an optically isolated DtoA convertor for simulating a remote potentiometer and adjusting the volume of the sound processor via the processor’s remote fader feature,

two optically isolated inputs to allow remote control of the volume.

The DF1 requires 12V DC which is available at the automation sound processor serial port connector.
