Q I recently bought an Xbox One X console and have it connected to my Yamaha RX-A2050 AV receiver. When I watch Atmos demo videos using the Dolby Access app on the Xbox, my AVR’s front-panel LED display reads “Dolby Atmos.” I get the same result when I watch Netflix shows with an Atmos soundtrack. When viewing Ultra HD Blu-rays with Dolby Atmos soundtracks, however, the receiver’s front panel will read “Dolby TrueHD.” Are Atmos and TrueHD the same thing? —Hans Furey / via e-mail

Q I’ve seen a couple of instances in Sound & Vision magazine of installations with a flat-panel TV for normal viewing and a projector and large screen for special viewings. If the screen comes down in front of the flat panel, how do you arrange room seating to accommodate both screen sizes? A 60-inch flat panel and a 100-inch projection screen for instance?—W.

Q I want to amplify just the dialogue on my TV. Is it possible to do that? —Glenn Goudeau

Q My system consists of a Sony XBR-X900E TV, a PlayStation 4Pro console, and a Yamaha YAS-207 soundbar. The PS4 Pro does not play Ultra HD Blu-ray Discs, so I’m planning to buy an Ultra HD Blu-ray player. Here’s my problem: I want to connect both the PS4 Pro and the disc player to the Yamaha, but the soundbar only has one HDMI input. I’ve looked around for an HDMI switcher that’s compatible with both 4K/60-Hz video signals and high dynamic range but haven’t been able to find one. Will I have to switch the cable connected to the soundbar from my sources on an as-needed basis to maintain best picture and sound quality? —Paul Trava / via e-mail

Q I own an Audio-Technica AT-LP120-USB turntable that I’ve modded. I’ve also purchased a Cambridge Audio CP1 phono preamp to connect the Audio-Technica to my Denon AVR-X6200W receiver. Can you help me understand how to hook the CP1 up to the Denon? I’ve tried many options but still fail to get sound. The turntable plays when plugged into another amp so I know it’s working correctly —Rodger Benson

Q I have an old Yamaha RX-V1900 7.1 receiver that is still going strong. I know I should upgrade to a newer unit, but I spent around $2,000 on it back in 2008. Here’s my question. I have two powerful subwoofers and would like to connect both using a Y-adapter since the receiver only has a single subwoofer output. Will that function properly, or is it not even an option? —Jarrod Agesen

Q I own an Integra receiver, Polk Audio speakers, and an Oppo BDP-105D Blu-ray player with a high-end DAC. I recently bought an iMac and am using it to download and store high-res audio files. What’s the best way to connect my iMac to the Oppo player? Both are set up in the same room about 20 feet apart. —Neil Levy
