DH46X 4 Source, 6 Zone Digital Audio Expansion Router
Pre-Construction
In a pre-construction installation, walls and ceilings are open with no drywall installed. This is
desirable and allows the installer greater access than in retro-fi t applications.
Before actually running any wire or cable, take the time to look around each room or area of the
house and plan your wire paths for maximum effi ciency. Look for routes through uncluttered
parts of the stud wall or ceiling that allow you to group all low-voltage (video, speaker wires, Cat-
5, telephone, etc.) wires wherever possible. It is a good practice to label both ends of all cables
and to protect wires by tying a plastic bag over the ends.
Note: Do not run low-voltage wires closer than 12" from high-voltage wires. If necessary,
cross low-voltage wires at a 90º angle to prevent interference.
Retro-Fit Wiring/PostConstruction
Retro-fi t installations are more diffi cult to complete than pre-construction because walls and
ceilings are intact. Typically wires must be fi shed into position through walls, fl oors and ceilings.
Holes must be cut; speakers mounted directly in the ceiling or walls with no rough-in brackets
and Touch Pads and local source wall plates must be mounted in existing drywall.
Pre-Wiring
DH46X to DHTP1 Touch Pads
The DH46X and all associated components are wired using Cat-5 terminated to the T-568A
Wiring Standard (Figure 2-2). When pre-wiring, run lengths of Cat-5 from the pre-determined
equipment location (the “head-end”) to each Touch Pad location. The Cat-5 routes all audio,
power, IR and status information needed for full system operation.
Note: For maximum performance over long runs (more than 150 ft) run an additional
16AWG 2-conductor wire for external power.
