Quick Start Guide

AutoPatch Precis SD Distribution Matrix

Overview

Because the Precis SD (Slam Dunk) Distribution Matrix is available in eight 
configuration sizes of RGBHV, four with and four without stereo audio, the illustrations 
in this guide may differ from the model(s) you purchased. For complete documentation 
for this product (including signal specifications), see the AMX AutoPatch CD or visit 
www.amx.com. This product supports full Device Discovery through the Duet module.

Precis SD systems are available in the following configurations; all models have front 
control panels.

* DVC – Digital Volume Control

General Specifications 

Installation

Rack Mounting

To rack mount a Precis SD enclosure:

1.

Attach the rack ears as shown in FIG. 2 (screws provided).

2.

Install in a rack leaving a minimum of one empty rack unit above and below 
(required); three empty rack units above and below are recommended.

Attaching Input & Output Cables/Wires

Before connecting all input and output cables/wires, attach only the first two inputs and 
outputs and execute a test switch (see “Completing the Installation,” next page). When 
the test switch is successful, attach the rest of the input and output cables and wires. 

500 MHz Video & Hi-Z Sync Connectors – BNC 

Five connectors are required to route an RGBHV signal. FIG. 3 shows five BNC cable 
connectors attached for routing R, G, B, H, and V signals to the destination device 
through Output 8. Input cable connectors are attached in the same way.

Stereo Audio Connectors – 5-Term 

Precis SD models featuring stereo audio have 5-position terminal block connectors 
that can be wired for balanced (differential) or unbalanced (single-ended) audio 
(FIG. 4).

Note: When using shielded twisted-pair wire, connect the shield (ground) at one end 
only (recommend receiving end) to minimize low frequency noise (see FIG. 5).

Source and destination devices require either balanced or unbalanced connections. 
More than one of the options shown in FIG. 5 can be used in the same system.

Establishing External Control (if applicable)

The Precis SD can be controlled by attaching an external control device/system to the 
CONTROL port or to the REMOTE port, which uses AutoPatch XNNet protocol for 
AMX AutoPatch devices.

Serial Control (PCs, AMX Control Devices, & third-party controllers)

Use the pinout in FIG. 6 when connecting a PC to the CONTROL port.
