LED Engine & RGBA Color Mixing of the 4BAR LT QuadBT
The 4BAR LT QuadBT employs a quad-color RGBA LED engine to deliver warm, natural washes with excellent skin-tone rendering thanks to the addition of amber. Across the bar you get 12 RGBA LEDs rated at 4 W each with a 50,000-hour life expectancy for reliable, low-maintenance performance. A tight 12° beam and 21° field provide focused projection that scales cleanly from uplights to stage/front-wash roles, while a 1.31 kHz PWM frequency supports flicker-resistant imaging for casual video capture.
- LED Array: 12 × 4 W quad-color (RGBA) LEDs; 50,000-hour rated life.
- Optics: 12° beam / 21° field for controlled, even wash coverage.
- Output Reference: 2,162 lux @ 2 m (per pod) for practical spacing and throw planning.
- Color Quality: Amber channel produces warmer whites and natural-looking color temperatures ideal for people-lighting.
- PWM: 1.31 kHz for smooth dimming and reduced visible flicker in typical event capture scenarios.
DMX Channel Structure & Bluetooth Control Integration
Choose the control path that fits your rig. For traditional programming, the fixture supports DMX over 3-pin XLR with 4-, 6-, or 19-channel profiles to access dimming, color mixing, strobe, and show parameters. For streamlined setups, the unit’s built-in Bluetooth® (v4.2) enables direct control from a phone or tablet using the BTAir app—no external hardware required. Wireless operation runs on 2.4 GHz with a max unobstructed distance of 150 ft (25.7 m), making it practical for small to mid-sized rooms. The included footswitch provides hands-free control, and the optional IRC-6 handheld remote adds simple, line-of-sight operation.
- DMX Profiles: 4 / 6 / 19 channels via 3-pin XLR.
- Bluetooth App: BTAir control (no dongles); Bluetooth 4.2 on 2.4 GHz.
- Wireless Range: Up to 150 ft (unobstructed) for mobile event layouts.
- Hands-Free: Included footswitch for color/program/blackout functions.
- Optional: IRC-6 remote for basic control without DMX.
Program Modes & Master/Slave Show Linking
The 4BAR LT QuadBT is show-ready right out of the bag. Use sound-activated programs that follow the beat, or select from automated fades and chases for hands-off operation when time is tight. For larger rigs, connect additional 4BAR fixtures in master/slave mode to mirror looks across multiple bars—ideal for even stage coverage and symmetrical room washes. The footswitch streamlines performance control with instant access to colors, program starts/stops, and blackouts, while Bluetooth/BTAir gives quick access to static colors and scenes from your device.
- Sound-Active: Built-in programs that respond to music dynamics.
- Auto Shows: Preconfigured fades/chases for quick deployment.
- Master/Slave: Coordinate multiple 4BAR units for unified looks.
- Performance Control: Footswitch access to colors, programs, blackout.
- App Convenience: Bluetooth/BTAir selection of static colors and scenes without a console.
How to Deploy
This quick guide gets the 4BAR LT QuadBT from bag to show-ready with clean cabling, proper coverage, and reliable control.
- 1) Tripod & Height: Open the included tripod and set leg spread for stability. Mount the bar on a 1 in (25.4 mm) pole and raise to the required trim—typical front-wash heights are 50–83 in (127–211 cm). Tighten knobs fully before powering.
- 2) Mount & Secure: Seat the bar on the stand spigot, align the clamp, and snug to prevent rotation. If using an alternate stand or T-bar, confirm the spigot is 1 in and load-rated for the fixture weight (7.2 lb / 3.3 kg).
- 3) Power & Cable Path: Connect AC (100–240 VAC, auto-ranging). Run the power lead down the rear of the stand and tape or tie for strain relief. Keep the footswitch and any DMX lines on the upstage side to avoid trip hazards.
- 4) Head Aiming & Coverage: Fan the four individually adjustable heads to cover your target: two angled for near-field (uplights or front line), two for mid-room or backdrop. Start with even spacing; fine-tune to eliminate hot spots. With a 12° beam / 21° field, expect focused pools that blend well when overlapped.
- 5) Control Path Selection:
- Bluetooth® / BTAir: Enable Bluetooth on your device, open BTAir, pair, and select static colors or scenes. Keep within ~150 ft (unobstructed) and avoid 2.4 GHz congestion when possible.
- DMX: Choose 4/6/19-channel mode to match your show file. Daisy-chain via 3-pin XLR. Address the bar, verify console patch, then test dimmer, color, strobe, and any chases.
- Footswitch: Place upstage or side stage; connect to the bar before power-up. Use for quick colors, program triggers, and blackout cues.
- Master/Slave: When using multiple 4BAR units, set one as Master (program or sound-active) and link others as Slaves for mirrored looks.
- 6) Color & White Point: Use the amber channel to warm skin tones for front-wash. For camera-friendly whites, blend R+G+B with a touch of A to reduce green cast and achieve natural color temperature.
- 7) Sound-Active & Auto: For no-console gigs, start with an Auto fade or chase, then audition Sound-Active at live music level. Adjust input sensitivity so programs respond without constant strobing.
- 8) Final Checks: Confirm all knobs are tight, cables are dressed, and heads clear the audience sightline. Walk the room to verify even coverage and adjust pan/tilt per head as needed.
