The Lab Gruppen E5:4 500W E-Series Installation Amplifier
is a feature-rich solution for professional audio installations. This amplifier is designed to deliver exceptional performance, flexibility, and energy efficiency, making it a top choice for mixed A/V installations.
HIGHLIGHTS
Power Output:
4 x 125W channels, configurable for constant voltage (70/100V) or low impedance (2, 4, 8, and 16 Ohms)
Energy Efficiency:
Energy Star certified, with low power consumption and minimal heat generation
Asymmetric Channel Loading:
Allows mixing and matching loads with different impedances for optimized system efficiency
Amplifier Technology:
IntelliDrive Energy Efficient Amplifier (IDEEA) technology, a proprietary Class-D design for high performance and low distortion
Rail Sensing Limiter (RSL):
Reduces signal clipping and optimizes output for varying load conditions
Auto-Standby and Power-On:
Automatically reduces power consumption to below 1W during idle periods
Cooling System:
Temperature-controlled fans with front-to-back airflow for efficient cooling
User-Friendly Controls:
Per-channel attenuation knobs, signal LEDs, and a high-pass filter (50 Hz) selectable via rear panel switches
Durable Build:
Compact 1 rack unit form factor with an aluminum front panel, designed for durability and ease of installation
Connectivity:
Balanced analog inputs and outputs on detachable screw terminals, along with a GPIO connector for system integration
Fail-Safe Protection:
Comprehensive circuit protection ensures reliable operation under challenging conditions
