AMX Precis Quick Start Manual

Overview
The Precis Series Distribution Matrix is available in various sizes and board
configurations; therefore, the illustrations in this guide may differ from the model(s) you
purchased. The Precis is available in the following models: Precis (300 MHz),
Precis 500 MHz (both in 8x4, 8x8, and 12x8), and PrecisHT (8x4 and 12x8). All
models can have either a front control panel or a blank front panel. The PrecisHT
comes with volume control. The Precis (300 MHz) and Precis 500 MHz have optional
stereo audio with or without volume control. For complete documentation for this
product (including individual board specifications), see the AMX AutoPatch Software &
Documentation CD or visit www.amx.com.

ESD Warning: Avoid ESD (Electrostatic Discharge) damage to
sensitive components; be sure you and the enclosure(s) are
properly grounded before touching any internal materials.
Rack Mounting
To rack mount a Precis enclosure:
1. Attach rack ears as shown in FIG. 1 (screws provided).
2. Install in a rack (we recommend leaving a minimum of one empty rack unit
above and below).
3. Secure enclosure to rack with screws.

Linking Multiple Enclosures (if applicable)
If the system has multiple enclosures (500 MHz models only), an "AutoPatch
Distribution Matrix Linking Quick Start Guide" has been provided. Using the
Ethernet port, link the enclosures according to the guide.
Attaching Input & Output Cables/Wires
For testing purposes, attach just the first two sources and destinations according to the
labels on the rear of the enclosure.
Video – RCA Connectors
RCA connectors for video are available in the PrecisHT only (see FIG. 5).
Video – BNC Connectors
BNC connectors are used for standard video, Y/c, and component video.
Y/c and Component signals (e.g., Y/Pb/Pr) require more than one BNC connection.
The example in FIG. 2 (top of next column) shows five BNC cable connectors attached
for routing an RGBHV signal through Output 8.

Stereo Audio – 5-Term Connectors
Models having audio boards with 5-position terminal block connectors can be wired for
balanced (differential) or unbalanced (single-ended) audio; see FIG. 3.
FIG. 3 Balanced audio Unbalanced audio
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. 4).
Source and destination devices require either balanced or unbalanced connections.
More than one of the options shown in FIG. 4 can be used in the same system.

Digital Audio – S/PDIF & TosLink Connectors (PrecisHT only)
S/PDIF connectors are coaxial, and TosLink connectors are optical (remove the
protective caps from the TosLink jacks).

Note: PrecisHT models can be ordered with either RCA or BNC connectors for video.
