System installers in search of a compact, flexible amplifier with Hi-Z and Lo-Z capabilities should check out the Lab.Gruppen E 12:2, a 1 RU, two-channel 1200W amplifier for mixed A/V installation applications. The E 12:2 utilizes IntelliDrive Energy Efficient Amplifier (IDEEA) technology to produce high power levels with very low distortion while drawing minimal mains current.

E-Series amplifiers also utilizes Lab.Gruppen's proprietary Rail Sensing Limiter (RSL) technology, which greatly reduces signal clipping to ensure high-quality audio output all the time. The amplifier is user-configurable for Hi-Z (70V) or Lo-Z. The RSL circuit senses rail voltage and optimizes each channel output for instantaneous load conditions. This allows for asymmetrical channel loading for optimized performance and efficiency. Total available output power can be allocated among the channels as required by the application. This makes it possible, for example, to drive a small sub on one channel and several 70V ceiling loudspeakers on the second channel.

Two-Channel Amplifier: 2 x 600W    IntelliDrive: 70V or 2, 4, 8, 16 Ohms    Energy-Efficient Class-D Amplifier    Asymmetric Channel Loading    Comprehensive Circuit Protection    Rail Sense Limiter (RSL)    Includes Screw Terminal I/O Blocks    Includes Power Cord    Limited 5-Year Warranty

Related Questions and Answers

Q: 1. Hello. Does anyone know if this is this compatible with the ASUS Z97-E/USB3.1 Motherboard?

A: Intel VROC Ready for X299/Z370/Z390 Series Motherboards. (Intel SSDs only.) AMD X399/X470/B450/X370/B350 Series Motherboards

Q: 2. Is this lens made in Germany?

A: The Zeiss Milvus 35mm f/2 ZE lens is made in Japan.

Q: 3. Is the focus throw on the 135mm in Nikon mount the same as on their Zeiss Classic predecessor?

A: The angular field of rotation of the focus barrel is 268 degrees for both lenses.

Q: 4. I bought the Zeiss Mills 35mm F/2 for use on my Nikon D850. However, I can't adjust my aperture or speed or ISO. What's wrong?

A: To use the ZEISS Milvus 35mm f/2 ZF.2 Lens for Nikon F on a D850, you will need to set the aperture to f/22 on the lens. Then, you may adjust the camera.

Q: 5. Can I use a Canon Extender EF 2x III on this Zeiss Milvus 135mm lens?

A: The ZEISS Milvus 2/135 is a high performing, apochromatic lens. The addition of a 3rd party optic in the light path will have an influence on the image quality that cannot be predicted. If you need to extend the focal length of the lens, our recommendation is to rent the extender and test the performance prior to committing.

Q: 6. Any difference between this newly released one and previous one? Is the lens designed again

A: The ZEISS Milvus 2/135 ZE shares the same optical design as the 'classic' version of the lens, with additional improvements in the anti-reflective coatings, a weather sealed barrel and a focus ring that does not telescope, allowing for use with a follow focus gear when using the lens for motion capture.

Q: 7. Are the lenses Auto Focus? Do they work good on nikonD500 ?

A: Manual focus only, which is a huge mistake in my opinion. I understand that Nikon and canon both were not open with Zeiss on their auto focus systems. On the other hand, the glass is some the best I have ever seen on a camera lens. and if you have the time to manual focus the shots you take you will not be disappointed. Unfortunately, I don't see many folks getting these lenses because of just that issue alone. especially with all the latest mirrorless camera bodies that have hit the market recently. The auto focus system is the only reason I personally upgraded to a z8 and I think it is fantastic.

Q: 8. Will this work on the 2019 Mac Pro?

A: This card is compatible with the new Mac Pro Tower.

Q: 9. How many aperture blades, and are they curved?

A: The ZEISS Milvus lenses; like their Zeiss Classic predecessors, have 9 aperture blades.

Q: 10. When is the lens going to be available?

A: The Milvus 2/135 ZE will begin shipping in November .
