Lab Gruppen E2:2 - 200 Watt Amplifier with 2 Flexible Output Channels for Installation Applications

Product Overview

The Lab Gruppen E 2:2 is a 200-watt, 2-channel Energy Star certified installation amplifier delivering 2 x 100 W per channel across Lo-Z (2–16Ω) and Hi-Z (70 V) outputs in a 1RU chassis. The most affordable model in the E Series line, the E 2:2 is suited for light commercial distributed audio applications — including small conference rooms, huddle spaces, hotel meeting rooms, and retail background music systems — where energy efficiency, flexible impedance configuration, and long-term reliability are required at a low per-zone amplification cost.

Product Description

The E 2:2 is the entry point of Lab Gruppen's E Series 2-channel installation amplifier range. Despite its modest 200 W total output, it shares the same IDEEA Class-D platform, Rail Sense Limiter (RSL) technology, and Energy Star certification as the larger E Series models — delivering consistent audio performance, flexible per-channel impedance operation, and low operating costs in the smallest, most cost-effective E Series package.

Each channel delivers 100 W at constant voltage 70 V or at low impedance (2, 4, or 8 ohms), independently configurable via the rear-panel RSL mode switch. This per-channel flexibility allows the E 2:2 to simultaneously drive a 70 V ceiling speaker tap circuit in a small office and a direct-drive low-impedance loudspeaker in an adjacent space — without external transformers or additional hardware. Asymmetric loading is supported, enabling the 200 W total to be allocated unequally across channels if zone requirements differ.

The IDEEA Class-D output stage achieves operating efficiency above 80%, with auto-standby below 1 W after 20 minutes without input signal and auto-power-on on signal return. These features satisfy Energy Star certification requirements and reduce idle power consumption in large-scale installations with many amplifier units. The GPIO contact-closure interface supports control system integration for remote power state management via Crestron, AMX, or building management systems.

Key Features

• 200 W Total Output, 2 Channels — 2 x 100 W at 2Ω, 4Ω, 8Ω Lo-Z, and 2 x 100 W at 70 V Hi-Z per channel.
• Energy Star Certified — Operating efficiency >80%; auto-standby <1 W; auto-power-on on signal return.
• Per-Channel Lo-Z / Hi-Z Configuration — Each channel independently switchable between low-impedance and 70 V constant-voltage via rear-panel RSL switch.
• IDEEA Class-D Output Stage — Lab Gruppen's IntelliDrive platform for efficient, low-heat amplification in a compact 1RU chassis.
• Rail Sense Limiter (RSL) — Per-channel dynamic limiter reduces clipping and protects loudspeakers under variable or asymmetric load conditions.
• Built-In 50 Hz High-Pass Filter — Per-channel switchable from rear panel for speaker protection in distributed systems.
• GPIO Integration — Contact-closure GPI/GPO connector for control system power state management.
• 1RU Form Factor — Standard 19" rack-mount; IEC 100–240 VAC mains input; designed and engineered in Sweden.

Frequently Asked Questions

Q: What is the E 2:2 best suited for compared to the rest of the E Series?

A: The E 2:2 is the lowest-power 2-channel E Series model (100 W per channel), making it appropriate for small single-zone or dual-zone applications where moderate SPL is sufficient — such as a small meeting room, reception area, or individual office zone. For larger rooms or higher speaker counts, the E 4:2 (200 W/ch) or E 8:2 (400 W/ch) provide more headroom.

Q: Does the E 2:2 support 100 V constant-voltage systems?

A: The E 2:2 supports 70 V Hi-Z operation. For 100 V constant-voltage systems, use the E 8:2 or larger E Series models that explicitly support 100 V Hi-Z mode.

Q: Can the two channels run in different impedance modes at the same time?

A: Yes. Each channel has its own independent RSL mode switch on the rear panel, so one channel can run at 70 V Hi-Z and the other in Lo-Z mode simultaneously.

Q: Is onboard DSP included in the E 2:2?

A: No. The E 2:2 is a pure analog installation amplifier. Signal processing such as EQ or delay should be provided by an upstream DSP processor or digital audio system connected to the balanced analog inputs.

Q: How many 70 V ceiling speakers can one channel of the E 2:2 support?

A: With 100 W per channel at 70 V, the number of speakers depends on each fixture's tap setting. For example, four speakers tapped at 24 W each total 96 W — within the channel limit. Do not exceed 100 W total tap load per channel.

Q: Is the E 2:2 Energy Star certified?

A: Yes. The E 2:2 carries Energy Star certification, achieved through operating efficiency above 80% and auto-standby consumption below 1 W after 20 minutes without input signal.

Q: What warranty does the E 2:2 include?

A: Lab Gruppen provides a 3-year warranty on E Series amplifiers covering components and factory workmanship, with an optional extended warranty program available through authorized dealers.
