The Precis DSP provides the ultimate solution for distributed audio by combining the functionality of a matrix switcher with the signal processing of an external equalization device. With robust features like a 10-band graphic equalizer, input gain, volume, tone, and balance control, the Precis DSP provides for exact customization of each output to support the attributes of the room or zone. The easy-to-use AutoPatch GraphicEQ setup software tool allows installers to manage all of the audio adjustments for the Precis DSP including adjusting the input gain to eliminate noticeable differences in volume as the user switches between various sources. Available in I/O sizes 8x8 or 18x18, the Precis DSP's standard RS-232 control port utilizes AutoPatch's BCS serial control protocol which allows it to be quickly and easily programmed when integrated into a control system.
