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.

Four-Channel Amplifier: 4 x 250W    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. Does this comes with the charger or is it only the battery?

A: The LP-E10 Lithium-Ion Battery Pack would be just the LP-E10 battery. It would not come with the charger. If you also need the charger, this battery uses the Canon LC-E10 battery charger (B&H# CALCE10).

Q: 2. Does this have accessory jack for handheld microphone?

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

Q: 3. it comes fully charged

A: No, it has about 30%-40% charge. It is always best to fully charge the battery before use.

Q: 4. would this be compatible with the T6 (not the i or s ) ?

A: Yes, with the EOS Rebel T6 EF-S 18-55mm IS II

Q: 5. can i use this battery with canon rebel 71i?

A: No, this is not the correct battery. This one is: Canon LP-E17 Lithium-Ion Battery Pack B&H # CALPE17.

Q: 6. What digital Mode does this radio transmit on. I do not mean the frequency hoping capability. Is Digital mode DMR or NXDN or P25?

A: According to Motorola's technical support, it is nether. Furthermore, there aren't any public whitepapers or specifications available on the DTR series to determine which digital radio standard (DMR, P25, dPMR, OpenSky, NXDN) is being employed. In my research, I did find one source that claimed it was a P25 radio, but Motorola said it was not. Conversely, if you are interested in a P25 radio, you can look at Motorola's APX portable radios.

Q: 7. Does this radio need to be programmed?

A: No it does not.

Q: 8. regarding Canon LP-E10 battery can i charge it in my charger, which i bought in europe? i mean does the battery i bought in us fit the elecricity in europe?

A: Most if not all battery chargers from Canon are multi-voltage. As long as your charger accepts this battery and you have the appropriate plug adapter to convert the European plug to a US plug, then you can use in the US.

Q: 9. 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: 10. Can the DR-E10 be used with a Canon EOS M6 Mark II?

A: No, the Canon DC Coupler DR-E18, BH # CADRE18 would be the correct battery coupler for the Canon EOS M6 Mark II. https://bhpho.to/3TyE13g
