Description

** IN GOOD CONDITION **

System installers in search of a compact, flexible amplifier with Hi-Z and Lo-Z output capabilities should check out the Lab.Gruppen E 4:2, a 1 RU, two-channel 400W amplifier for mixed A/V installation applications. The E 4:2 utilizes IntelliDrive Energy Efficient Amplifier (IDEEA) technology to produce high power levels with very low distortion while drawing minimal mains current.

E-Series amplifiers also utilizes Lab.Gruppen's proprietary Rail Sensing Limiter (RSL) technology, which greatly reduces signal clipping to ensure high-quality audio output all the time. The amplifier is user-configurable for Hi-Z (70V) or Lo-Z. The RSL circuit senses rail voltage and optimizes each channel output for instantaneous load conditions. This allows for asymmetrical channel loading for optimized performance and efficiency. Total available output power can be allocated among the channels as required by the application. This makes it possible, for example, to drive a small sub on one channel and several 70V ceiling loudspeakers on the second channel.

Benefits

400W amplifier carrying 2 flexible output channels in a high power density 1 rack unit form factor saves rack space and system cost
Energy efficient with Energy Star certification for supreme green credentials and exceptionally low lifetime running costs
Flexible IntelliDrive permits delivering the 2 x 200W at constant voltage 70V or low impedance (2, 4, and 8 ohms) on any channel
Asymmetric channel loading allows mixing and matching loads with different impedances to maximize overall system efficiency and inventory utilization
High-efficiency amplifier with low power consumption and minimized heat generation lowers demands on the installations' mains distribution and cooling systems
IDEEA outputs stage based on proprietary, state-of-the-art Class-D amplifier technology for superior performance
Comprehensive fail-safe circuit protection ensures continued operation even under reduced operating conditions
Auto-standby and auto-power-on reduces power consumption to below 1W in non-operating cycles
Rail Sense Limiter (RSL) greatly reduces signal clipping and ensures simple configuration for constant voltage and low-impedance loads
Built-in 50 Hz high-pass filter selectable per channel available on rear-panel switch
Per-channel attenuation knob and signal LED on rear panel for simple commissioning
Efficient cooling with temperature-controlled fan with front-to-back airflow
Aluminum front panel with power and temperature LEDs and per-channel signal and limit LEDs
GPIO connector with power control and indication for further system integration
Balanced high-quality analog inputs and amplifier outputs on detachable screw terminals
