"What you get is two very different sounds from your kick drum, fed into two separate channels on your mixing console. This means you can have more thump, more snap and overall added punch to your kick sound. You are left to mix the two outputs to suit your needs and to better fit in the mix. This is ideal for live setups when you need extra control and don’t want to have additional mics on the kit. It’s even better for studio recording, where you can always have an extra microphone capsule on any source for the added ease of mixing later on."
"One capsule, the condenser, which requires phantom power, certainly delivers the snap, with a crisp mid frequency response and super-fast transient response. The other dynamic capsule brings the bottom end that you want in a kick drum, without sounding too flat and lifeless. The two combined result in a lively drum sound that you would be very hard-pressed to find with just one single microphone. The overall result is a detailed kick in the arse that lets your drummer make his or her presence felt in a solid fashion."
