Lab.gruppen Brings Double Channel Density to its E Series of Commercial Install Amplifiers

CATEGORISED IN :   News / Products / Training

Lab.gruppen expands its E Series of commercial installation amplifiers.

Lab.gruppen has expanded its innovative and energy efficient E Series of compact 1U installation amplifiers with the introduction of the first four-channel models in the range, the E 10:4 and E 5:4, as well as the highly cost-effective new two-channel E 2:2. Now with a total of six models to afford integrators with unprecedented flexibility in system specification, the newly expanded E Series marks the 10th anniversary of Lab.gruppen’s first major entry of 2U, 8 channel solutions for the commercial installation market with C Series in 2006.

“The C Series of amplifiers quickly became one of our most successful products, not only because of its superb sound and durable build quality, but also because of its power density and flexibility,” observes Lab.gruppen Product Manager Klas Dalbjorn. “However, with the expanded E Series, now we can offer the same power density with an even lower current draw, Energy Star certification and reduced overall costs coupled with unprecedented configuration flexibility for operation into low impedance or 70V loads.”

With introduction of four-channel models, now E Series can offer eight channels configurable as any of 21 different power output and channel combinations in the same rack space as one 2U C Series unit. Options include one-to-one alternatives for the C 20:8X (with two E10:4 in a 2 U space) and the C 10:8X (with two E 5:4 units).

The new flagship model of the E Series, the E 10:4, provides four discrete inputs and four flexible output channels producing 1,000 W of maximum total output at 4, 8, 16 ohms or into 70V. Nominal maximum output per channel is 250 W, but with the E Series’ proprietary asymmetric power loading capability, one channel can produce output beyond the nominal maximum when other channels have lower power requirements. Each channel may be individually optimized to drive either a low impedance (4 16 ohms) or a 70 V load. The E 10:4 is certified Energy Star 3.0 compliant, and its extraordinary flexibility allows users to maximize overall system efficiency and inventory utilization.

The new E 5:4 also provides four channels of Lab.gruppen amplification with all the same features as the E 10:4, but with a maximum total output rating of 500 W (4 x 125 W nominal at 4 16 ohms or 70V), while the new two channel addition, the E 2:2 (2 x 100 W) allows installers an exceptionally cost-effective option for lower power applications.

“With six models now in the line, the audio consultant or systems integrator can configure even the most complex systems for the greatest cost efficiency and lowest energy consumption, all within the same amplifier family,” notes Dalbjorn.

All six E Series amplifiers feature Lab.gruppen’s exclusive IDEEA (IntelliDrive Energy Efficient Amplifier) output stage for extremely low power consumption and heat emission.  The unique Rail Switching Limiter circuit optimizes the output for instantaneous load conditions, ensuring a superior power-to-current draw ratio for reduced running costs and minimal environmental impact.

Other installation-oriented features of all E Series amplifiers include detachable screw terminal blocks for input (balanced) and output connections, and 50 Hz high pass filter switchable per channel, auto power on/off functionality, GPI facility for external control, comprehensive circuit protection and fault indication, and low-noise temperature controlled fans.
