Each input of the RM424 can be switched to any combination of four zone outputs. The outputs are all on balanced XLR connectors. Remote Volume Control inputs provide each zone with the means for external volume control. Additionally, the microphone inputs feature selectable ducking for effective paging. The front-panel speaker and headphone output make pre-assignment monitoring easy, each channel includes a switch to monitor before assigning an output. The RM424's front panel is simple to use, while its back panel provides enough functionality to shine in any four zone environment.

A quite enjoyable, funny, mystery.
Format: Kindle
I really enjoyed this one, it was funny, great characters, fantastic pacing, solid twist at the end, although one thing was obvious to me but I can't say it because thats a spoiler. But I am really looking forward to the next book.

Good first book in a series.
Format: Paperback
I had read all of the Lord Edgington mysteries and decided to try this series since I believe the author does a very good job. Definitely a different vibe than the other series, but great all the same. I THOUGHT that I had for once solved the mystery before the end but I was only partially right. Definitely recommend; I will be purchasing all the other books in this series.

Great start to a new series
Format: Kindle
Well, here we go with a new series from one of my favorites, Benedict Brown! I was excited when I learned that we had a new series to read from this author, again based in the 1920s. I love his writing style and his attention to detail of this era in all his stories. And this one was no exception. We meet Marius Quin, whom we've met before, but in his own setting this time. A writer who is struggling to write his next book. When he runs into an old friend and is invited to a New Year's Eve party, he decides maybe that's just what he needs to get his creative juices going. What he doesn't know is that chaos is about to be unleashed! Marius and his friend Bella now have to work together to piece things together to figure out who did it and why. Will they figure it out in time before the guests all leave? What an excellent story from start to finish. I'm really looking forward to more in this series. Highly recommend!

Worked well near the equator
Style: SPF 50
I bought this product because I was going to be in the field for a month, outside, every day, all day, in Tanzania at high altitude. A severe sunburn would be hard to treat in the remote area we were in, but also I am very careful about protecting my skin from aging. I had to have mineral based sunscreen because as a whitewater kayaker I know it’s the only truly water resistant kind and it was going to be sweaty. And since I knew I was going to be putting it on every day, and we didn’t have running water in the field (bucket showers only) I didn’t want it to feel gross. (I really wanted to try the spray but I didn’t want to put anything pressurized in my luggage.) And I had already discovered the Coola face sunscreen (30spf version) which had impressed me with how silky smooth and not greasy it is. Now this IS greasier because it is a higher SPF. BUT I think this product is as good as you’re going to get with the protection you’re getting. Like I said, I’m a white water tiger, so I have used a LOT of mineral sunscreens. This was hands down the most comfortable one I’ve used. And it was effective. I didn’t burn once—only time I did burn was when I forgot to put it on one day toward the end of the trip, when we were out for just a couple hours—and I got the first 2nd degree burn I’ve ever had in my life. That was what this stuff had protected me from, all day every day, the entire trip. I did tan a little but I think that was mostly from the few times I was not covered during short bouts or it was cloudy. For my face I used the Coola 50spf face product.

Love this stuff!
Style: SPF 50
I use this every day and I love how it is frangrance free and creamy. I have a very fair complexion and I will say it leaves a slight white cast but it doesn’t bother me because it almost makes my fairness more creamy looking. My skin texture has improved since wearing it daily and no allergies from it. I highly recommend especially if you have fairer skin otherwise it may leave a cast .
