Scott is back to talk about a listener question that could affect all of us. He's been looking at the Denon AVRX4700, and it's supposed to have Dolby 5.1.4 or 7.1.2. What's the third digit for? Scott says that the third digit tells you how many speakers you can use overhead. It's a Dolby Atmos at Home Specs.The first mask is the number of surround speakers you can have, the middle number is the subwoofer. But if you want an Atmos system, the third number is the one you want to pay attention to. Scott would rather have Dolby 5.1.4 for Atmos because it gives you a greater sense of sound moving from front to back and vice versa. Dolby 7.1.2 will only give you two.
The Denon receiver is also listed as 9.2 receivers. So it can support two subwoofers? Scott says the receiver has two subwoofer outputs, but they will carry the exact same signal. So don't be confused by it.
