Get multiple audio sources in sync with your video, using the AD-300 Pro Audio Delay Box from Datavideo. This multifunction sound box offers 5 x input channels: a pair of RCAs, a pair of XLR-1/4" combo inputs, and an additional XLR-1/4" input on the front panel. The combo inputs feature mic- and line-level switches along with phantom power switches to provide +48V phantom power for condenser microphones. The unit offers a built-in mixer to route the incoming signals to a pair of stereo outputs with both balanced XLR and RCA connections to choose from.

Each channel on the AD-300 offers a digital delay adjustable from 0 to 3000 ms, allowing you to get professional synchronization from multiple sources. In addition, each channel offers a compressor, limiter, expander, and gate, allowing you to tame audio levels and reduce noise for more professional-sounding results. High-pass and low-pass filters along with an 8-band EQ on every input provide precise control over frequency content, giving you additional audio-sculpting power.

Great fluffy ones
Color: White, Size: King(2Pack)
I originally order this pillows to use as Shams for an oversize king comforter but they came out to small for that, but after seen the qualitu i kept them for my daily use ones. The size is perfect, and the quality feels much higher than the price suggests. It's soft yet supportive, holds its shape well, and adds a real touch of comfort to the bed. For the price, it’s a fantastic deal. The pillow look big and they are super fuffly. Highly recommend if you're looking for great value without sacrificing quality!

Fantastic pillow
Color: White, Size: King(2Pack)
Super comfortable for a bit of a firm pillow it is king size and lightweight, it gets pretty warm pretty quick, I stack both pillows on top of each other in the same pillow case for extreme support but that's just me.

King size great pillows!!!!!
Color: White, Size: King(2Pack)
I ordered this 2-pack of king-size pillows to upgrade my bed, and I’m so glad I did. The size is perfect for a king bed and instantly made everything look more full and put together. When they arrived, the pillows fluffed up nicely and felt soft yet supportive. They’re not too flat and not overly firm, which makes them really comfortable whether you’re sleeping on your back or side. I’ve been using these for a bit now and they’ve held their shape well through the night. They provide good neck and head support without feeling stiff, and they don’t go flat by morning. What I like most is how versatile they are — great for sleeping but also perfect for propping up in bed while reading or watching TV. For a two-pack, the quality is honestly impressive. Overall, these are a great value and exactly what I was looking for. If you want comfortable, well-filled king-size pillows that look and feel great, I would definitely recommend this set.

Comfy pillows! Excellent deal
Color: White, Size: Queen(2Pack)
I received these pillows shrink-wrapped flat as a pancake. But I've received other things this way including whole king-sized mattresses and they always puff up to normal size once you pop them out of the plastic wrap. These pillows puffed up pretty quickly. I did shake them and pound on them a little off and on for about an hour before slipping some pillow cases onto them. Their not super fluffy but not too flat. I like that their soft yet have a little support. My husband really likes his too. We both get a good sleep on these. I'm a side sleeper so it's really comfy for me to have some "squishiness" like these have. As far as quality goes, these are nicely stitched and the fabric feels soft. The pillows are rather lightweight and I won't know how durable these are until we've used them for a while.
