The ARM-750D is a high-brightness professional DLP projector engineered for large venues such as auditoriums, conference halls, lecture theatres, houses of worship, and large corporate presentation spaces. With an impressive 7500 ANSI lumens brightness and WXGA (1280×800) native resolution, it delivers powerful, high-definition visuals that remain clear even in well-lit environments.
The projector features a 0.65″ DMD chip with DLP display technology, ensuring sharp image rendering, excellent color consistency, and reliable long-term performance. With a 15000:1 contrast ratio, the ARM-750D produces deeper blacks and enhanced detail, making presentations, charts, and multimedia content appear crisp and vivid.
The ARM-750D uses a dual-lamp system (2 × 350W lamps) to achieve strong brightness and operational flexibility. Users can operate in dual-lamp mode for maximum brightness or single-lamp mode for extended lamp life.
Lamp lifetime options:
Dual lamp mode:
Normal: 2000 hours
ECO: 4000 hours
Single lamp mode:
Normal: 4000 hours
ECO: 8000 hours
This flexible configuration improves reliability and reduces maintenance downtime for professional installations.
The projector is equipped with a powered zoom and focus lens with 1.35× optical zoom, allowing precise image adjustment and easier installation. It can project a 100-inch screen from approximately 3.8 meters and supports screen sizes from 40 inches up to 300 inches.
Additional professional lens adjustments include:
Vertical lens shift: ±55%
Horizontal lens shift: ±10%
These features allow flexible placement without image distortion.
The ARM-750D offers multiple input and control interfaces to support a wide range of AV systems:
Inputs
VGA ×1
BNC ×5
DVI-D (HDCP supported) ×1
HDMI ×1
Video ×1
S-Video ×1
Outputs
VGA output ×1
Control Interfaces
RS232 input ×1
RS232 output ×1
RJ45 LAN control ×1
Wired remote input and output
These options allow integration with professional AV distribution systems and control networks.
The projector includes several advanced adjustment technologies for large-screen installations:
Vertical keystone correction: ±30°
Horizontal keystone correction: ±15°
Corner keystone adjustment
Pincushion and barrel correction
Edge blending support for multi-projector setups
These features make the ARM-750D ideal for large screen projection walls and multi-projector installations.
The ARM-750D supports professional remote monitoring and control systems, including:
Crestron RoomView LAN Control
AMX Discovery
PJLink compatibility
These systems allow centralized control of the projector within enterprise or campus environments.
The projector is designed for long operating hours and demanding environments. It features:
HEPA ESD dust filter for improved internal protection
Side lamp and filter access for easier maintenance
Operating temperature range of 0°C to 40°C
High-altitude operation up to 2700 meters
The projector operates at approximately 36 dB noise level, ensuring relatively quiet performance for large venue installations.
Dimensions: 490 × 201 × 421 mm
Weight: approximately 16 kg
Its robust build makes it suitable for permanent installations, ceiling mounts, or professional AV setups.
The ARM-750D comes with essential installation accessories:
Power cord
VGA cable
Remote control with batteries
User manual (Chinese and English)
The ARM-750D WXGA DLP Projector combines 7500 lumens brightness, dual-lamp reliability, advanced lens shift, and professional AV connectivity, making it an excellent solution for large-venue projection, corporate events, educational institutions, and professional AV installations where high brightness and installation flexibility are essential.
