Overview and Specifications Configuration and Control Configuration Information Precis DSP systems are pre-engineered to switch stereo audio for two configuration sizes (8x8 and 18x18). Control Options Precis DSP systems support two different protocols: BCS (as ASCII characters sent through the RS-232 serial port) and TCP/IP (with external APWeb Server module). Several control options are available for Precis DSP systems.
Installation and Setup Installation and Setup Site Recommendations When placing the enclosure, follow the recommendations and precautions in this section to reduce potential installation and operation hazards. For complete specifications, see the tables on page 11. Choose a clean, dust free, (preferably) air-conditioned location. Avoid areas with direct sunlight, heat sources, or high levels of EMI (Electromagnetic Interference).
Installation and Setup 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.
Installation and Setup Installation Procedure A flow chart showing the basic installation sequence is in FIG. 2. The procedure which follows provides general steps with references to detailed information found in later sections of this chapter. After the basic sequence is complete, see page 21 for fine tuning the audio with APGraphic EQ. FIG. 2 Installation procedure Caution: To prevent overheating and airflow restriction, avoid placing high-heat producing equipment directly above or below the enclosure.
Installation and Setup Attaching Inputs and 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. Precis DSP models have gold-plated RCA connectors for routing stereo audio.
Installation and 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 – AMX AutoPatch protocol via the CONTROL (RS-232) port TCP/IP – requires an external module; see the APWeb Server module documentation An external serial controller is any device that can send and receive A
Installation and Setup t Setting Table for Prec4. Open the serial communication software and set the port settings to match the Precis DSP default settings (see table to the right). The settings on the PC serial communication software and the enclosure must correspond to each other. If a change is required to make them match, change the PC’s settings. The system is ready to install and open APGraphic EQ for initial setup.
Installation and Setup Executing a Test Switch Using APGraphic EQ Execute a test switch to verify the system is working properly before attaching all inputs and outputs. Before executing the test switch, make sure the first two source devices and the first two destination devices are connected to the input and output connectors. Note: For directions for executing a test switch using BCS commands, see page 30. We recommend executing a test switch that routes Input 1 to Output1 and Output 2.
Installation and Setup 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. We recommend recording your system’s serial number in an easily accessible location.

Fine-Tuning with APGraphic EQ Fine-Tuning with APGraphic EQ Overview APGraphic EQ software is used for system setup and adjusting audio functionality.* The software is available at www.amx.com (permissions required). For more information, see the Release Notes and the Readme file.
Fine-Tuning with APGraphic EQ Executing Switches Before fine-tuning the system for its final location, route a few switches to check that the system is working properly and to determine what adjustments are needed. This section provides basic information for executing switches using the CrossBar. For complete control information using APGraphic EG, see page 27. To execute switches with the APGraphic EQ CrossBar: 1. Open APGraphic EQ (see page 18). 2. From the Options menu, select Show > CrossBar View.
Fine-Tuning with APGraphic EQ Adjusting Digital Input Gain Inputs are set to unity gain at the factory and have a gain adjustment range of -10 dB to +10 dB. Input gain adjustments should be made before the outputs are fine-tuned. Inputs cannot be muted. Purpose and Application of Input Gain Adjustment Adjusting input gain (the nominal level of the signal from the source device) allows source signals of varying amplitudes to be equalized before they are routed and the volume is adjusted.
Fine-Tuning with APGraphic EQ Adjusting Equalization Bands and 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. The adjustment range for each band is -12 dB to +12 dB. Balance is normally adjusted as part of system setup and fine-tuning but can also be adjusted any time during operation.
Fine-Tuning with APGraphic EQ Adjusting Tone Tone is normally adjusted along with balance and volume as part of system setup and fine-tuning but can be adjusted any time during operation. Note: The button immediately left of the Reset button is used to toggle between the Tone and EQ sliders. When the EQ sliders are visible, the button says Tone; when the Tone sliders are visible, the button says EQ. To adjust tone for an output: 1. Using the CrossBar, route an input to the output needing adjustment. 2.
Controlling the System Controlling the System Control Options After the initial setup (in which APGraphic EQ is used for test switches, volume control, and fine turning), the Precis DSP can be controlled using any of the following: AMX Control Devices APControl 3.
Controlling the System APGraphic EQ The APGraphic EQ has a CrossBar (interface with crosspoints for switching) that can be used for ongoing control after the system is set up and fine tuned. For instructions on installing and opening APGraphic EQ software on a PC, see page 18. APGraphic EQ has three views (windows) for adjusting and routing signals. APGraphic EQ main interface – used for adjusting volume (page 22), tone (page 25), and equalization bands and balance (page 24).
Controlling the System Customizing the CrossBar The CrossBar can be customized to reflect your individual system and preferences. Icons and custom channel names can be added to the Input and Output buttons (font size and icon size are also adjustable). The background color of the CrossBar can be customized using the Window Color dialog box. Customized settings are automatically saved. To add icons and custom names to input and output buttons: 1. From the CrossBar, right-click an input or an output button.
Controlling the System BCS Commands Precis DSP models can be controlled by entering BCS (Basic Control Structure) commands into a terminal emulation program (e.g., TeraTerm, PuTTY, or HyperTerminal). BCS command equivalents for all DSP functionality adjustments are provided for advanced users and programmers who wish to create their own control programs; see the Instruction Manual – BCS (Basic Control Structure) Protocol at www.amx.com.
Controlling the System Executing a Test Switch with BCS The following test switch routes Input 2 to Output 1 (the level does not need to be specified since the Precis DSP only switches audio). To execute a test switch using BCS commands: 1. Enter the following BCS command line: CI2O1T When the “T” appears, the system has successfully executed the command. If any other characters appear, the command was not successful. Verify that the source signal is audible at the destination.
Appendix A – Programmer’s Interface for System Diagnostics Appendix A – Programmer’s Interface for System Diagnostics System Component Information The Precis DSP displays system information in its splash screen* for diagnostic purposes. The information indicates the current status and well-being of the system components.
