I grew up in Elkhart, Ind. In many ways it’s your typical small town, but also happens to be known as the RV manufacturing capital of the world, the place Alka-Seltzer was launched, and home to Crown Audio, a Harman company.

In my early production days in northern Indiana we joked that we had no more than three degrees of separation from a Crown Audio worker. I’ve always had a great deal of respect for the Crown name.

This could stem from hometown pride, but I think it’s more the fact that they have built a reputation on quality. The first amp I ever owned was an old CE I even had one of Crown’s early six-channel amps, the CP, which they discontinued soon after I bought it. It comes in four models: All are two-channel amps, the largest of which—the —is able to produce 2, watts at 4 Ohms bridged.

For this review, Crown sent me the model, which produces watts into each channel at 4 ohms and 1, watts in bridged mode. It weighs nine pounds—not what you’d expect if you’ve used earlier Crown amps, or any professional power amplifier for that matter.

So my first impression of this new Crown amp was that it was a prosumer product—designed for home theater or certainly something other than a serious pro audio environment. That prosumer feeling, I quickly learned, is just an exterior perception.


After spending more than a week evaluating this amplifier on a range of loudspeakers, I can report that the Crown XLS DriveCore 2 power amplifier—with drivecorr light weight and super-efficient Class D technology—is capable of producing great audio. Listening to the speakers in different environments, I found that the amplifier, including the built-in DSP, provided clean, clear sound.

DSP is accessible and controlled via three buttons and a small LED screen that, honestly, took a little getting used to.

I kept backing out of the menu instead of saving my settings.

This, however, is probably linked more to my inability to follow instructions; I am still unable to figure out duplex copying on the copy machine.

Stereo, Bridged Mono and Input Y. Stereo is pretty self-explanatory and is the factory default for the amp. Bridged Mono takes the input from channel one and crowwn it to the output one.

In Bridged mode, you have more crossover filter drivecote Using Input-Y mode, the amp uses the input from channel one and sends it as two separate inputs to power both outputs.

With the DSP, you can select each channel and control it independently—a very cool feature allowing, for example, a two-way speaker on channel one and a subwoofer on channel two. Both can be fed the same full-range signal from the console. Other features in the menu allow the user to turn off the LED level indicators if the amp is in an area where it would be distracting to the audience. Many options are available, including turning off the blue “style” lights.

The clip LEDs cannot be disabled, which makes sense. The LCD screen can also be set to a sleep time, so it dims as well.


If installed, it features an aux control terminal that allows a sleep erivecore via a contact closure. Finally, in the menu is a security feature that disables the buttons so the DSP cannot be changed by your arch drlvecore from the church down the street … or the elementary-aged kids playing hide and seek backstage. For the demo, I did my best to use the amp in varying combinations—both stereo and mono bridged. I compiled a series of different types of speakers: Listening to the speakers in different environments, I found the amplifier, including the built-in DSP, provided clean, and clear sound.

DSP settings are not very robust, however. For example, there is no EQ or delay. While drivecire sound was excellent, I was amazed at how quiet the cooling is for this unit.

Review: Crown XLS DriveCore 2 Power amplifier – Church Production Magazine

It does have a fan to draw air, but I am not sure if I have ever heard it. I even made sure to crank the audio for a while on my favorite song so see if it just needs some encouragement to run. I never heard the fan.

I would recommend this particular unit for portable criwn, churches with portable systems, youth groups and any number of smaller audio needs.

The larger versions would certainly be capable of driving larger systems, although the DSP may be a limitation. Copyright c Production Media, Inc.
