Designed by a team of former AKG personnel, the black Austrian Audio OC818 Dual Set Plus is a matched pair of large-diaphragm studio condenser microphones, offering detailed audio capture and immense sonic customization that's ideal for stereo miking solo instruments, drum kits, and ensembles. The handmade 1" ceramic capsule features two gold-plated polymer membranes to enable multiple polar patterns. Utilize the 5-position switch to set the OC818 to figure-8, hypercardioid, cardioid, omnidirectional, or wide cardioid. Each diaphragm is routed to a separate output connector for dual-channel recording, which allows you to design custom polar pattern responses across five frequency bands via the open-source PolarDesigner plug-in or achieve a tweakable stereo image thanks to the StereoCreator plug-in (also open-source).

Alternatively, the secondary output can be connected to the optional OCR8 Bluetooth module if you wish to enjoy convenient wireless control and selection of 255 polar patterns via the free iOS/Android PolarPilot app. Front-panel switches are provided for easy access to the pad and roll-off settings. Set the pad to -10 or -20 dB to avoid distortion when miking loud sources such as drums or guitar cabinets. Activate the high-pass filter at 40, 80, or 160 Hz for attenuation of low-frequency problems, including rumble and proximity effect. The OC818's housing is constructed of zinc-aluminum alloy for strength and durability. The OC818 Dual Set Plus includes two shockmounts, two mic clips, a stereo bar, two mini 5-pin XLR to 3-pin XLR cables, two windscreens for mitigating noise from breaths and blasts of air, and a protective carry case for easy transport and storage of the entire bundle.

Dual Set Plus vs Live Set
  • Both bundles include two OC818 microphones, two mic clips, two windscreens, and two mini-XLR cables

  • Two-stage pad (-10 or -20 dB) to prevent distortion
  • High-pass filter with three positions (40, 80, or 160 Hz) for reduction of low-frequency rumble and excessive bass
Microphone Features
  • 5-position polar pattern switch for figure-8, hypercardioid, cardioid (dual-cardioid mode when using the secondary output), omnidirectional, and "preset mode," which defaults to wide cardioid, but can be set to anything via the free iOS/Android PolarPilot app and optional OCR8 Bluetooth dongle (required for PolarPilot control)

Snuggly.
Size: Standard, Style: Solid, Color: Light Green
Well made, accurate color, very warm and roomy, cosy to wear. Very pleased with product. I will be warm this winter! Took about 10 days to ship, then longer to arrive as international. I’ve ordered another and it shipped within a couple of days this time. I reccomend.

Great Buy! Nice robe!
Size: Oversize, Style: Solid, Color: Grey
I love this robe. I bought it for myself as a Christmas present ( 2024) and it’s the best robe I have ever had. It’s soft, warm, long, and very comfortable. I’ve washed it several times over the past year and it still maintains its same quality, looking and feeling as brand new.

Warm and comfy
Size: Adult, Style: Solid, Color: Black
Super soft, warm and comfy. I bought the adult size. I'm 5'11" and medium build. It's roomy and comes down to the middle of my shin. Typical robe style except that it does not open. It slips on like a shirt. May not be great if you have to go to the bathroom a lot. Otherwise awesome, I bought 2 for my sister's.

Keeps me nice and warm in Alaskan winters!
Size: Oversize, Style: Solid, Color: Dark Purple, Size: Oversize, Style: Solid, Color: Dark Purple
As you've probably guessed from the title of my review, I live in Alaska. In my part of the state, the temperature gets down to as low as -25°F in the winter, so I decided to get this to help keep myself warm. (Part of it was self preservation; my mom flat-out refuses to turn the heat up past 69° F.) And it doesn't help that I have defective fat either. Apparently my body thinks I live in the Southern Hemisphere or something, because it keeps me warm in what would be winter for them, but is summer for me. The opposite happens in the winter for me. So I decided to bite the bullet and make the purchase...and let me tell you, this blanket/robe works MARVELOUSLY! It's so fluffy and warm, I rarely have to turn on my space heater anymore. Now I'll admit, I was a little hesitant to bite the bullet because I'm a BBW, and most things labeled 'oversized' really aren't. (All my plus-size peeps out there know the struggle.) However, this blanket/robe is different! Not only does it fit, I have plenty of room to spare. For the record, I'm 5'6 1/2 - the half matters, trust me - and 321 lbs. But it's a little long...which is to be expected, since it's made for somebody up 6'5. So what I did to prevent mine from dragging was tie the belt underneath the pocket every time I need to leave my room, as seen in the picture. (Yes, I can still use the pocket during this time) That way, I don't have to sacrifice the extra room in favor of a shorter length. I also like how the sherpa is inside the hood as well. Between it and the elastic cuffs at the wrist, I could practically live in this blanket/robe! I also purchased this in the adult size, but in dream blue. Again, I was nervous because I didn't know if it would fit me or not. Kinda felt like I was pushing my luck there. Fortunately, my fears were unfounded. Not only does it fit as well, I have a bit of room to spare. (See the last picture if you wanna compare the two sizes.) It's not as long as the oversized version, though. The adult size stops about halfway down past my knees, whereas the oversized can pool around my feet. It's not quite as roomy on me as the oversized one is either, but I bought it to walk around outside in, so that's a good thing. More room = more air getting inside to make me cold. As of the date of this review, however, the slit no longer has the ability to snap closed on either of these robes. That was a bit of a bummer. But everything else is perfect, including the purple and blue being true to color. If you're on the fence about this blanket/robe, just do it! You'll be glad you did.

Fire resistant saved my life!
Size: Oversize, Style: Solid, Color: Grey
Saved my life! I love this snuggie. I'm 5'6" and the oversized drags when I walk. Its my outdoor fireplace blanket. Went to a neighbors last night and the fire tipped over towards me. Hot ash landed on my snuggie. After a stop drop and roll, the only thing damaged was my snuggie. Yes, I need to order another, but the material did great with fire. On a normal night, it's warm and cozy and keeps me warm on chilly outdoor nights.
