System installers in search of a compact, flexible amplifier with Hi-Z and Lo-Z capabilities should check out the Lab.Gruppen E 10:4, a 1 RU, four-channel 1000W amplifier for mixed A/V installation applications. The E 10:4 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, several 70V ceiling loudspeakers on the second channel, and a pair of full-range, low-impedance loudspeakers on the two remaining channels.

Related Questions and Answers

Q: 1. How do I hook up my brogan car amp to my home stereo system?

A: Most automobile head units are 12 volt DC systems and not compatible with home systems which are 110-120 VAC/60 Hz. The speaker outputs are typically mismatched for the impedance of home speakers as well.

Q: 2. Does this radio need to be programmed?

A: No it does not.

Q: 3. Will the traditional Motorola stye surveillance earpiece and mic work with radio?

A: Yes, the Motorola DTR700 Digital 2-Way Radio will work with traditional Motorola earpieces such as the Motorola HKLN4601 Single Wire Surveillance Earpiece with In-Line Mic and PTT (MOHKLN4601).

Q: 4. Does this have accessory jack for handheld microphone?

A: Motorola does not offer a handheld microphone for this radio.

Q: 5. How can I turn off the amplifier's sleep mode?

A: We are having BIG problems with the Sleep Mode. Even when there is signal, the unit is going in to sleep mode. We stood in front of a group of 15 at a church yesterday, all of them angry that we don't have a solution for this. Most times the unit does not come back on with signal, we have to power cycle, which causes a significant pop in the speakers.

Q: 6. Is there an amp that is just like the C60, but without the telephone input and without paging? To be used to replace our Bogen C35 that we use just as an amp, in our church. I know, we don't have to use the telephone and paging section, but doesn't that add to the expense. Thank you much. Jerry Wilbanks, Sr.

A: The Behringer Eurocom SN2108 would be a good alternative if you are looking for a 70v amplifier without the telephone paging feature. This amplifier features 80 watts of total power.

Q: 7. Can I attach this to the battery plate on the back of the Atomos Ninja Assassin while simultaneously powering a Sony a6300 via DC coupler?

A: Well I power a BON 5.6 monitor as well as the Teradek Sidekick with the battery. So I'm guessing yes

Q: 8. how do i hook it up?

A: It depends on application. What purpose does the amp serve (i.e. background music with paging etc.). Let me know how you plan to use it and I can probably poit you in the right direction.Andy

Q: 9. Can this amp be used to power MCM 55-10345 tweeter array? These are not powered and can't be heard, or would some other small amp work? Any suggestions. Thanks, EYD.

A: Yes it can.

Q: 10. Does this include the rack brackets with purchase?

A: Yes. The rack mounting kit is included.
