About the Lab Gruppen E 8:2
The Lab Gruppen E 8:2 is an 800W, 2-channel installation amplifier delivering 2 x 400W in a high-power-density 1U chassis. Its flexible IntelliDrive technology allows each channel to operate at constant voltage (70V) or low impedance (2, 4 or 8 Ohms) independently, with asymmetric channel loading enabling mixed-impedance configurations for greater system efficiency. Energy Star certified, the amplifier draws below 1W in auto-standby. A proprietary IDEEA Class-D output stage, Rail Sense Limiter, per-channel attenuation and a selectable 50Hz high-pass filter simplify commissioning, while comprehensive fail-safe circuit protection and a temperature-controlled front-to-back cooling fan support reliable long-term operation.
Lab Gruppen E 8:2 — buyer FAQs
What is the Lab Gruppen E 8:2 and what is it designed for?
The Lab Gruppen E 8:2 is an 800W, 2-channel amplifier built specifically for fixed installation applications. It delivers 2 x 400W in a 1U rack chassis, keeping rack space and system costs low. Its IntelliDrive outputs handle constant voltage (70V) or low-impedance loads (2, 4 or 8 Ohms) on any channel independently, making it suited to a wide range of installed audio environments.
Who makes the E 8:2 and where does it sit in their range?
The E 8:2 is made by Lab Gruppen, a Swedish manufacturer founded in 1979 and dedicated to professional power amplifiers for touring and installed sound. The E series targets installation applications, and the E 8:2 sits at the efficient, compact end of that offering, combining Energy Star certification with a high-power-density 1U form factor aimed at minimising running costs over the lifetime of an installation.
What does asymmetric channel loading mean on the E 8:2?
Asymmetric channel loading means the two output channels of the E 8:2 can drive loads with different impedances at the same time. A single unit can simultaneously run, for example, a constant-voltage 70V circuit on one channel and a low-impedance speaker load on the other. This flexibility reduces the need for multiple amplifier types across a system, improving overall efficiency and simplifying inventory.
How energy efficient is the second-hand Lab Gruppen E 8:2?
The E 8:2 carries Energy Star certification and is built around a Class-D output stage that generates minimal heat, reducing demands on mains distribution and cooling. In non-operating cycles, auto-standby drops total power consumption to below 1W, while a temperature-controlled fan with front-to-back airflow manages heat during operation. Together these features are intended to keep lifetime running costs low.
What should I check when buying a used E 8:2?
Confirm that all per-channel attenuation knobs and rear-panel switches (including the 50Hz high-pass filter selector) operate correctly, and that the front-panel LEDs for power, temperature, signal and limit all respond as expected. Check the condition of the GPIO connector and that auto-standby and auto-power-on functions work. Used units sometimes come with a rack case. The live listings on this page show current condition details, and purchases on 10K Used include a 21-day warranty covering major functional faults.
