Page 7: Esd Warning
Grounding straps, conductive smocks, and conductive work mats are specifically designed for this purpose. Anyone performing field maintenance on AMX AutoPatch equipment should use an appropriate ESD field service kit complete with at least a dissipative work mat with a ground cord and a UL listed adjustable wrist strap with another ground cord. -
Page 8: Important Safety Information & Instructions
There are no user serviceable parts inside an AMX AutoPatch product; service should only be done by qualified personnel. If you see smoke or smell a strange odor coming from your AMX AutoPatch product, turn it off immediately and call technical support. -
Page 9: Information Et Directives De Sécurité Importantes
Placez uniquement des fusibles de calibre exact dans les boîtiers. Veillez à ce que la prise de courant soit proche de l’appareil et facile d’accès. Veillez à ce que votre appareil AMX AutoPatch soit installé sur une surface stable ou qu’il y soit fermement maintenu. -

Page 16: Configuration & Control
BCS Serial Control Protocol The Precis DSP can be controlled with an external serial controller that sends and receives ASCII characters via the CONTROL (RS-232) port. AMX AutoPatch has developed a command language, BCS (Basic Control Structure) Protocol, for programming control operations and for diagnostic purposes. -
Page 17: Installation & Setup
These recommendations address potential hazards that are common to all installations: Elevated Operating Temperature The maximum rated ambient temperature for Precis DSP enclosures is 95° F (35° C). All equipment should be installed in an environment compatible with the manufacturer’s maximum rated ambient temperature. -
Page 18: Unpacking
Caution: We recommend attaching all power cords to a surge protector and/or an AC line conditioner. Unpacking The Precis DSP is shipped with one enclosure per shipping box. The invoice is sent separately; a packing list is attached to the outside of each box. Each box contains the following items:... -
Page 19: Rack Installation
Installation Recommendations Write the system’s serial number in an easily accessible location before installing the Precis DSP in a rack. Viewed from the rear, the system’s serial number is located to the left on the end of the enclosure. Use earth-grounded power cords / system with the Precis DSP. - Page 20 To install and set up a Precis DSP in a rack: On the side of the Precis DSP, remove the bottom two screws closest to the front panel (FIG. 3). Align the holes on one of the rack ears with the empty holes on the side of the enclosure and replace the screws (three screws for the 1 RU;...

Page 21: Attaching Inputs & Outputs
Input and output connectors are the attachment points for source and destination devices that connect to the system. Viewed from the rear of a Precis DSP enclosure, the inputs (for sources) are on the left side of the enclosure, and the outputs (for destinations) are on the right side. -
Page 22: Applying Power
(also listed on page 9). Always use an earth-grounded power cord / system with a Precis DSP. The source electrical outlet should be installed near the Precis DSP, easily accessible, and properly grounded. Power should come from a building branch circuit. We strongly recommend using a dedicated line for the system’s power. -
Page 23: Attaching An External Controller
Installation & Setup Attaching an External Controller The Precis DSP can be controlled externally by attaching an external control device/system that uses one of the communication protocols listed below: BCS (Serial) – ASCII sent over a null modem serial cable via the CONTROL (RS-232) port XNNet –... -
Page 24: Installing Apgraphic Eq Software
Before installing, see the “PC Requirements for APGraphic EQ” on page 17. To install and open the APGraphic EQ program: Close any software on the PC that could communicate with the Precis DSP over its serial port (e.g., HyperTerminal). Insert the AutoPatch CD with APGraphic EQ into the CD drive. -

Page 26: Technical Support
Before contacting technical support with a question, please consult this manual. If you still have questions, contact your AMX representative or technical support. Have your system’s serial number ready. Viewed from the rear, the system’s serial number is located to the left on the end of the enclosure. -
Page 27: Fine-Tuning With Apgraphic Eq

Page 30: Adjusting Equalization Bands & Balance
Fine-Tuning with APGraphic EQ Adjusting Equalization Bands & Balance Precis DSP models provide a 10-band graphic equalizer to boost or cut the various frequencies (bands) for each output. Each equalization band spans one octave and is identified by its center frequency. The bands are set for a flat response (0 dB) at the factory. -
Page 31: Adjusting Tone
Tip: The Tone bands for an output can be set to 0 (flat response) by clicking the Reset button. Repeat Steps 1 through 4 for additional outputs as required. Click the EQ button to return to the main interface. Precis DSP Instruction Manual... - Page 32 Fine-Tuning with APGraphic EQ Precis DSP Instruction Manual...

Page 33: Controlling The System
Enter 8 or 18 (depending on the configuration) in the # Input Channels field and in the # Output Channels field (the VM Number can be left at 0; the Precis DSP switches on either VM 0 or VM 2). -
Page 34: Apweb
Note: APGraphic EQ has a drop down list with two virtual matrix choices, VM 0 (all) and VM 2 (audio); either virtual matrix can be used since the Precis DSP has a single (stereo audio) virtual matrix. Executing Switches Using the CrossBar The crosspoint images in the CrossBar field represent the intersections of the input channels (buttons on the left) and the output channels (buttons along the top). - Page 35 From the CrossBar View menu, select Window Color. Select the color. Click OK. Note: The background color of the APGraphic EQ and Input Gain views can also be changed. Check each view’s menu options for Window Color. Precis DSP Instruction Manual...
