DH44 4 Source, 4 Zone Digital Audio 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
DH44 to DHTP1 Touch Pads
The DH44 and all associated components are wired using Cat-5 terminated to the T-568A Wir- ing Standard (Figure 2-2). When pre-wiring, run lengths of Cat-5 from the pre-determined equip- ment 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.

Touch Pads to Speakers
Run 16AWG 2 conductor stranded copper speaker wire between Touch Pad locations and speaker locations.
Local Sources to Touch Pads
Local sources are only available within the area that they are installed. They will not be avail- able to other areas of the house as they are not distributed by the DH44. Run lengths of Cat-5 from any local (in-room) source to the Touch Pad located in that area.
