Cambridge Sound DSLG22 Lab Gruppin 2x100 70v Amplifier - 911.0845.900

Product Overview

The Cambridge Sound DSLG22 (part number 911.0845.900) is a Lab Gruppen E Series 2x100 W amplifier configured for 70 V sound masking systems. It is the designated power amplifier when a Dynasound DS3008 or DS3002 generator drives a 70-volt distributed loudspeaker system. The compact 1U chassis delivers 200 W across two flexible output channels. Energy Star certification keeps lifetime running costs low in always-on masking installations.

Product Description

The DSLG22 is built on Lab Gruppen's E Series platform, a line of compact two- and four-channel installation amplifiers designed for energy-efficient commercial systems. Its IntelliDrive output stage lets each channel deliver 2 x 100 W either at constant-voltage 70 V or into low-impedance loads of 2, 3, or 8 ohms, so the same amplifier covers both distributed masking zones and conventional speaker lines. In a Cambridge Sound / Dynasound deployment, the DSLG22 amplifies the masking signal from a DS3008 or DS3002 generator and feeds 70 V loudspeaker runs throughout the facility. The 1U rack format conserves equipment room space, and the wide 70-265 VAC operating range tolerates unstable mains supplies. Frequency response extends from 2 Hz to 40 kHz with a 20 kOhm input impedance. At 9.3 lbs, the amplifier is light enough for wall-mounted racks and remote equipment closets.

Key Features

• 2 x 100 W in 1U — high power density two-channel amplifier in a single rack unit.
• IntelliDrive Flexible Outputs — each channel runs at constant-voltage 70 V or into 2, 3, or 8 ohm low-impedance loads.
• Built for 70 V Masking Systems — the specified amplifier when a DS3008 or DS3002 is the generator for a 70-volt system.
• Energy Star Certified — low power draw and exceptionally low lifetime running costs for 24/7 masking duty.
• Wide Frequency Response — 2 Hz to 40 kHz for full-bandwidth masking and audio signals.
• Universal Mains Tolerance — 100-240 VAC nominal with 70-265 VAC operating range.
• Compact and Light — 9.3 lbs (4.2 kg) in a standard 19-inch, 1U chassis.

Typical Applications

• Open offices — powers 70 V masking loudspeaker runs across large floor plates.
• Private offices and conference rooms — drives distributed masking zones fed from a DS3002/DS3008 generator.
• Healthcare facilities — amplification for masking systems protecting patient conversations.
• Call centers — continuous-duty amplification for high-density masking coverage.
• Financial and legal offices — reliable 70 V power for speech privacy systems.

FAQ

When do I need the DSLG22 in a sound masking system?
Use it when a Dynasound DS3008 or DS3002 serves as the generator for a 70-volt distributed system; the DSLG22 provides the amplification stage for the 70 V loudspeaker runs.

Can it drive low-impedance speakers instead of 70 V lines?
Yes. The IntelliDrive output stage delivers 2 x 100 W at constant-voltage 70 V or into 2, 3, or 8 ohm loads on any channel.

How much rack space does it need?
One rack unit (1U). The chassis is 19 inches wide, 1.75 inches tall, 10.9 inches deep, and weighs 9.3 lbs.

Is it efficient enough for 24/7 operation?
Yes. The E Series design is Energy Star certified and engineered for exceptionally low lifetime running costs, which matters for masking systems that run continuously.
