Video: Panamax MR4000 power line conditioner and surge protector

Protect your expensive gear with this home theatre essential

by Crutchfield's Video Team

Panamax makes products that are the unsung heroes of your home theater or stereo setup. The MR4000 is a power line conditioner and surge protector, which not only protects against power spikes such as lightning, but also cleans up the dirty power coming out of your wall outlets so your expensive receivers, amps, and TVs get the cleanest electricity possible. Think of it as an insurance policy for your precious gear, one that will keep it all running smoothly for life.

Read video transcript

Hi, I'm JR and this is the Panamax MR4000. You might call it a surge protector or a piece of power protection. It is all of that, and it is an important part of any kind of home stereo or home theater. Power spikes, lightning coming in, who knows what could happen, and lots of these things do. There is a power button on this model, and in addition to the seven AC outlets the MR4000 has a VM or automatic voltage monitoring, which means it's monitoring the amount of power it's getting from the wall so that I can do something about it when it sees a little bit too much or not enough power. Brownouts, surges, things like that, it's going to handle it. It has a current rating of 15 amps. If you have any questions on this model, give Crutchfield a call, chat with us online, send us an email, we're ready to help you get the right power port for your home theater.

We'd love to know what you think

Audition speakers before you buy

SpeakerCompare simulates the sound of home and car speakers through your headphones. It lets you compare sonic characteristics between speakers so that you can make a more informed shopping decision.

Why selecting your headphones is important

SpeakerCompare tailors your listening experience to the exact headphones you have, so that what you hear is comparable to auditioning speakers side-by-side in person. Knowing which model headphones you’re using lets us remove any sonic coloring from your experience.

Two different listening modes

In an actual listening room, you'd find that some speakers play louder than others when fed the same amount of power. In equal power mode, you'll hear these differences in loudness as they naturally occur between speakers.

In equal volume mode, we've made the loudness of each speaker about the same. This gives you a more direct comparison of subtle voicing differences between speakers.

Nothing beats listening to speakers in your space

SpeakerCompare gives you a sense of the sonic differences. But performance in the real world is affected by the acoustics of your car or home, your choice of amplification, and your source material. We still believe that the gold standard for auditioning speakers is hearing them in your own environment — that’s why we offer a 60-day money-back guarantee.
