Home Theater Wiring in Northern Virginia | Expert Installation

Challenge

A cinephile homeowner was converting a 20x15 basement room into a dedicated home theater with a 4K laser projector, 120-inch screen, and a full Dolby Atmos 7.2.4 speaker system requiring 13 speaker locations including four in-ceiling height channels. The room had only one electrical outlet and no low-voltage wiring. The homeowner wanted zero visible cables and a dedicated equipment closet adjacent to the theater.

Solution

AJ Long Electric installed two dedicated 20-amp circuits for equipment power (one for audio, one for video/projector) with a Panamax power conditioner. We ran 13 CL2-rated speaker wire runs from the equipment closet to each speaker location, including four ceiling runs for Atmos height channels. A 50-foot active HDMI 2.1 cable was routed from the equipment rack to the projector mount at the ceiling. Cat6 ethernet, coaxial, and a conduit for future cables were included in each run. All cables terminated at labeled wall plates.

Challenge

A couple in a modern townhome wanted a 75-inch wall-mounted TV with a 5.1.2 Atmos sound system in their open-concept living room, but the room had no provisions for concealed wiring. The TV wall was an exterior wall with spray foam insulation, making cable fishing extremely difficult. The existing single outlet was on the wrong wall for the entertainment layout.

Solution

We installed a recessed power outlet and dual-gang low-voltage pass-through behind the TV location, fishing cables through the insulated exterior wall using specialized flexible drill bits. Five in-wall speaker wire runs were routed to wall-mounted surround speakers, two ceiling runs for Atmos height channels, and a subwoofer cable was run to the corner location. A dedicated 20-amp circuit was added for the equipment, separate from the room's lighting circuit.

Challenge

A music-loving family wanted distributed audio in six rooms across three levels of their split-level home: kitchen, living room, master bedroom, two kids' rooms, and a covered patio. The challenge was routing speaker wire between all three levels of the split-level to a central equipment location in the lower-level media room, with minimal wall penetration in finished spaces.

Solution

AJ Long Electric installed twelve in-ceiling speakers (two per zone) wired back to a six-zone amplifier in the media room. We routed speaker wire through the central stairwell chase and interior wall cavities to reach each level, using the attic above the upper level and the crawlspace beneath the lower level where possible. Each zone received a keypad volume control, and the system was connected to a Sonos amplifier for streaming access in every room.

Challenge

A custom home under construction included a 25x18 basement media room and the builder's wiring plan only included basic outlet and cable TV provisions. The homeowner wanted to pre-wire for a 9.2.6 Atmos system, three rows of seating with floor outlet access, a 150-inch projection screen, and a dedicated equipment room with structured wiring panel connecting to the media room, outdoor living space, and four other rooms for future distributed audio.

Solution

Working during the rough-in phase before drywall, we installed a 30-cable bundle from the equipment room to the media room including fifteen speaker wire runs for the 9.2.6 system, three HDMI runs, Cat6 to each seating row, and spare conduits. Four additional rooms received two-speaker pre-wire runs for future distributed audio. The media room received three dedicated 20-amp circuits. A structured wiring panel in the equipment room provides the central connection point for the entire system.
