Quick Start Guide
Precis DSP Matrix Switchers
Overview
The Precis DSP is available in two models:
• FGP37-0808-00P, 8x8 (1 RU)
• FGP37-1818-00P, 18x18 (2 RU)
In addition to being a stereo audio router, this product has Digital Signal Processing
(DSP) for the following audio features: volume, tone, balance, 10-band graphic
equalization, and input gain. These features are adjusted by using the APGraphic EQ
software program. APGraphic EQ and the Instruction Manual – Precis DSP Matrix
Switchers (containing complete product documentation, including full specifications for
the system and for the DSP features) are available at www.amx.com
.
The Precis DSP supports full Device Discovery through AMX’s AutoPatch Duet
module (firmware v1.2.0 or later is required).
General Specifications
Installation
Rack Mounting
To rack mount a Precis DSP enclosure:
1. Attach the rack ears as shown in FIG. 1 (rack ears and screws provided).
2. Place enclosure in rack and attach front-mounting screws to hold firmly in place
(we recommend leaving a minimum of one empty rack unit above and below).
Attaching Input and Output Cables
To attach input and output cables:
1. Insert RCA plugs into RCA jacks according to labels on the enclosure (FIG. 2).
Applying Power
Important: We recommend attaching all power cords to a surge protector and/or an
AC line conditioner.
To apply power:
1. Attach the power cord to the Precis DSP enclosure and to the power source (turn
on the power source if necessary).
2. Press the “I” side of the enclosure’s power switch.
The Power Indicator on the front of the enclosure illuminates.
3. Apply power to the external control device and then to the source and
destination devices.
Establishing Serial Control
(PCs, AMX Control Devices, and Third-Party Controllers)
Installation of the Precis DSP requires a PC to run the APGraphic EQ software.
The Precis DSP can be controlled with APGraphic EQ or with another type
of external control device/system attached to the serial port. Use the pinout in FIG. 3
when connecting the PC (or other serial controller) to the Precis DSP serial port.
To establish external serial control:
1. Plug a null modem serial cable that matches the pin diagram in FIG. 3 into the
CONTROL (RS-232 / DB-9) port on the enclosure (FIG. 4).
2. Plug the other end of the cable into the serial port on the serial controller/device.
3. Open the serial communication software and set the port settings to match the
settings in the table in FIG. 4. The settings must match.
Startup with APGraphic EQ
APGraphic EQ software is used during system setup for adjusting the audio DSP
functionality. This software is available at www.amx.com
.
