Compact, rugged, and efficient, the MX401 Four-Channel Stereo Mixer from Rolls is a deceptively flexible analog audio mixer designed to make mobile sound setups and field recording hassle-free. The unit features four channels of XLR audio input and balanced stereo XLR outputs, with all XLR I/O featuring individual mic/line level selection. The MX401 also sports level control for each input channel, master gain control, an extra 3.5mm stereo output for headphones or as an aux send, and 15V of phantom power selectable for each input. Crucially, the MX401 can not only run off of the included 15 VDC power supply, but also on two common 9V alkaline batteries for completely mobile, outlet-free operation.
Elegant and Efficient I/O
- Four balanced XLR input channels with mic/line selection
- Level control and stereo pan control per channel
- Balanced stereo XLR outputs provide a stereo feed for monitors, PA system, or audio interface
- Selectable mic/line level for each XLR output
- Flexible unbalanced 3.5mm stereo output for headphones or record send
- Main output gain control with clip indicator
Flexible Power Options
The MX401 features two options for power, including a standard 15 VDC power supply (included) and the ability to run on two 9V alkaline batteries, placed in dedicated slots on the side. This ensures the MX401 can perform well in either a fixed position setup or a mobile setup, such as a field recording system. The unit also comes with selectable 15V phantom power, allowing individual selection of powered inputs.

PRICE DOUBLED IN 2 WEEKS
Size: 18 Count (Pack of 1), Size: 18 Count (Pack of 1)
I rescue standard poodles mostly. I also train service dogs. My pack of "poodles" has all sizes and ages. This is not for profit , it is to save lives. Until 2 weeks ago -date now is: 08/17/2022- the price of these were around 20.00. My dogs all loved them. I have a buffet table with lots of storage I use to store the treats and it has room on top for all the treat jars. In the afternoon or evening, they'd get a hard, chewy treat like ears. Standard poodles love to chew . They could finish off one of the ears in minutes. These treats are quiet large and thin. They do smell but they are natural foods. NO WAY can I afford over 40.00 for 18 ears. Did pigs go exttict? Did they quit growing ears? How could They raise the price to cost double the amount? I looked at other ears on Amazon & the other brand i get which starts with a p- has not gone up. Paws- clipping. They have some Bizarre names so guess I'll just double my order for them. I have way too many dogs to give treats to. I want to be fair to all of them. They are my kids & will get the best I can offer. I did wait a few weeks before writting this. I also dropped my Sub & Save with this.

Finally a Toy My Pitbull Hasn’t Destroyed in 5 Minutes
Color: Blue+Red, Color: Blue+Red
I have a 65 lb pitbull who destroys most toys almost immediately, so I’m always skeptical when products claim to be “indestructible.” Most toys last maybe a few minutes in my house before pieces are everywhere.
These have actually held up surprisingly well.
The material feels durable and thick enough to handle really aggressive chewing, and so far my dog hasn’t been able to destroy them like he does with most other balls and squeaky toys. That alone makes these worth it to me.
I also really like the size. They’re large enough that I don’t have to constantly worry about him accidentally swallowing them or choking while playing, which is a huge plus for bigger dogs.
The squeaker inside also keeps him interested longer since he usually gets bored quickly with toys that don’t make noise or bounce around well.
If you have a strong chewer or larger dog and you’re tired of replacing destroyed toys constantly, these are definitely worth trying.
