No phone trees. No high-pressure sales. Just clear answers from people who do this every day.
Most home theater installs look fine in a photo and feel disappointing in person. The TV is too high, the speakers are aimed at the wall, the subwoofer is buried in a corner, and the remote requires a 12-step manual to turn anything on. We do this differently.
Global Low Voltage designs, installs, and tunes audio video systems for residential and commercial clients across Southern California. We mount TVs at the right height, place speakers where they actually image properly, hide wires inside the wall, and calibrate everything so movies sound like movies and music sounds like music.
Whether you want a clean wall-mounted TV in the living room, a 7.2.4 Atmos theater in a dedicated room, in-ceiling audio across the whole house, or a weatherproof outdoor system for the backyard, we build it around how you actually use the space — not a brochure.
Our commercial AV side covers conference rooms with video walls, restaurants with distributed audio, retail with background music zones, and hospitality with in-room TV systems. Same standard: clean install, intuitive control, and equipment that’ll still work three years from now.
Every project starts with a conversation about how you’ll use it and ends with a walkthrough where we hand you a single remote (or a phone app) that controls everything in one tap. No ‘oh, you have to switch this to HDMI 3 first.’
Centered, level, at proper viewing height, with cables fully concealed in the wall.
Dialogue you can understand, music with real imaging, bass you feel without overpowering.
Universal remote or app — one button watches Netflix, dims the lights, and starts the system.
Independent zones in the kitchen, patio, master, and office — all controlled from your phone.
Weatherproof speakers and amplifiers that survive the elements and still sound great.
We measure room response and calibrate — not just plug it in and hope.
Fixed, tilting, full-motion, or recessed mounts on any wall type — drywall, brick, tile, or stone.
5.1, 7.1, and 7.2.4 Atmos systems with in-wall, in-ceiling, or freestanding speakers.
Full theater rooms with acoustic treatment, riser seating, blackout treatments, and starlight ceilings.
4K laser projectors, ambient-light-rejecting screens, and motorized drop-down options.
TV configuration, picture calibration, app login, and cable cord-cutter onboarding.
Sonos, HEOS, and Control4 multi-room systems with in-ceiling speakers and individual zone control.
Patio, pool, and landscape speaker systems with weatherproof amplifiers and discrete placement.
Logitech Harmony, Control4, RTI, and URC programming for true one-button operation.
Apple TV, Roku, NVIDIA Shield, and gaming console setup with proper HDMI and audio routing.
We start with a no-pressure call to understand your space, goals, budget, and timeline. You'll get straight answers, not a sales pitch.
A senior technician walks the property, measures cable paths, photographs problem areas, and confirms what will and won't work.
We deliver a written scope, equipment list, and fixed quote — engineered for your building, not pulled from a template.
Our W-2 technicians install on schedule, clean as they go, and treat your property like their own. No subs, no surprises.
Every drop is tested, every camera is calibrated, and you get full documentation plus a real human to call when you need us.
The center of the screen should sit at eye level when you’re seated — typically 42 to 48 inches off the floor for a sofa, higher for a bar or kitchen counter. Mounting too high (a very common mistake) causes neck strain and washes out the picture. We measure your seating, sightlines, and viewing distance before drilling a hole.
No — a great theater experience can live in a multi-purpose family room. A dedicated room lets you control light, acoustics, and seating for the best possible result (and Atmos overhead channels), but most clients are thrilled with a properly designed 5.1 or 7.1 system in their living room with a quality 4K TV and a calibrated soundbar or in-wall setup.
Yes. We run all power and HDMI inside the wall using in-wall rated cables and recessed power kits — code-compliant, clean, and invisible. For brick, tile, or concrete walls where in-wall isn’t possible, we use low-profile raceways color-matched to the surface.
Yes. Modern systems run on apps for iOS and Android — Sonos, Control4, URC, Roon — and many include Alexa and Google voice control. We also program physical universal remotes for clients who’d rather not pick up a phone every time. Either way, one button starts a ‘Watch Movie’ or ‘Listen to Music’ scene.
