Lab Gruppen E 10:4 Power Amplifier (4 x 250W)

The Lab Gruppen E 10:4 is a high-performance, 1000-Watt 4-channel power amplifier engineered explicitly for commercial audio installations, multi-zone environments, and distributed sound systems. Housed in a compact 1U rack space, this Class D amplifier delivers 250 Watts per channel into low-impedance loads (4 Ω, 8 Ω, 16 Ω) or high-impedance constant voltage lines (70V Hi-Z).

Built with Lab Gruppen’s proprietary IDEEA (IntelliDrive Energy Efficient Amplifier) technology, the E 10:4 allows installers to mix and match different speaker loads across individual channels, eliminating the need for multiple specialized amplifiers.

Why Choose the Lab Gruppen E 10:4?

Asymmetric Power Loading: Distribute power unevenly across channels. Run high-power low-impedance subwoofers on channels 1 and 2 while running a 70V ceiling speaker chain on channels 3 and 4 simultaneously.
Energy Star Certified Efficiency: Features an auto-power-down state that draws less than 1 Watt of power after 20 minutes of audio inactivity. The unit wakes up instantly within milliseconds of detecting an incoming signal.
Fail-Safe Loudspeaker Protection: Integrated Rail Sensing Limiter (RSL) and Average Limiter (AVL) technologies dynamically monitor real-time speaker loads to eliminate signal clipping, overheating, and short circuits.
Front-to-Rear Cooling: Highly efficient internal fan cooling prevents thermal shutdown, allowing the amplifier to remain operational inside crowded, unventilated A/V rack enclosures.
Set-and-Forget Controls: The rear panel features detented volume potentiometers, individual Hi-Z/Lo-Z switches per channel, and a 50 Hz High-Pass Filter (HPF) to prevent 70V transformer saturation.

Ideal Commercial Applications:

- Bars, Cafes & Restaurants: Easily power high-fidelity background music inside a main dining hall alongside separate volume zones for outdoor patios and restrooms.
- Corporate Offices & Boardrooms: Delivers pristine vocal clarity for distributed ceiling speakers during video conferences, presentations, and town hall events.
- Retail Stores & Shopping Malls: Maintains uniform audio coverage across massive retail floor plans via high-impedance 70V line configurations.
- Houses of Worship: Ideal for driving reliable, localized sound fills to side chapels, lobbies, cry rooms, and administrative wings.

Frequently Asked Questions (FAQ)

1. Can I mix 70V and 8-ohm speakers on the same Lab Gruppen E 10:4?

Ans: Yes. The E 10:4 supports asynchronous loading. You can set Channel 1 to drive low-impedance (4/8/16 Ω) speakers and Channel 2 to run a 70V distributed high-impedance line using the independent toggle switches on the rear panel.

2. Does the Lab Gruppen E 10:4 require constant maintenance?

Ans: No. The E 10:4 is designed for permanent commercial installation. Its solid-state design, automated protection limiters, and front-to-back automated fan cooling minimize physical hardware stress for long-term operational longevity.

3. What connector types does this amplifier use?

Ans: The amplifier utilizes industry-standard, detachable Phoenix-style screw terminals for both balanced audio inputs and speaker outputs, ensuring secure and rapid field wiring.
