The FP-ALC1 is the ideal choice in many applications where consistent mono audio levels are needed from professional sources with varying audio output levels. Power connections are made using either the full-size barrier block or a dc power jack located in one end panel.

The FP-ALC1 is a single channel (mono) module featuring a detachable terminal block for the input and output. A single user adjustment makes installation simple and efficient. The gain adjustment is set as high as possible with the loudest source without the INPUT OVERLOAD indicator flashing. No further adjustments are needed. Sound systems fed from variable audio source levels, such as multiple CD changers, satellite receivers or paging sources benefit from consistent levels.

Common FP-ALC1 applications include paging outputs from telephone systems, music-on-hold feeds for telephone systems, background or foreground amplifier inputs in sound systems, voice feeds in communications/intercom systems.

Best place for head
Size: Queen (Pack of 1), Color: White
Do you love not getting sleep and sweating all over your pillow at night when you are asleep? If so then don't buy this pillow! If you want a good nights sleep and cool pillow like me this is the one. Ive always been ehh towards spending so much on a pillow but its 100% worth it, I sleep so much better and it forms to my head and keeps me cool at night. Great support even for my big head and comes with a bag of extra stuffing if you want to have a little more firmer pillow. Highly recommend

Oversized
Size: Queen (Pack of 2), Color: White
I have chronic neck pain. I am forever buying new pillows. Sometimes I think I found the perfect pillow but then three months later they’re losing their loft. I thought I would give these pillows to try since the stuffing is removable. Now these pillows are really oversized. To the point where I thought that they had sent me king-size pillows but I double checked the packaging and they were Queen. I ended up having to buy king-size pillowcases for them because they just barely fit in the queen size and the pillowcases would always end up pulling back from the edge. So that’s a negative one star there. Now I’ve been sleeping on these pillows for a while and they have held up well. I did end up removing some of the stuffing because it was just too much. I’m a side sleeper and when I use this pillow, it does a good job of keeping my neck in alignment. However, the pillow tends to migrate up as I sleep. Or I tend to slip down off the pillow, either or. So that’s why I’ve removed a second star. Maybe if I removed more stuffing that wouldn’t happen, but then I feel like the loft would be too little. I will say that these provide great support when sitting up in bed reading or watching TV. So would I buy them again? Probably not. Am I going to keep using them? Yes

Soft and smooth cover
Color: Grey, Size: Body(20"X 54")
This is a nice pillow cover overall. The fabric feels good and it's comfortable to sleep on, especially compared to a more basic cotton cover. It is maybe a little thinner than I expected, so if you want something thick and heavy this probably isn't that. But for a soft smooth cover that fits and feels decent, I think it's worth it. No major complaints from me after using it.

These are the ones you want
Color: Grey, Size: Body(20"X 54")
May need to iron them out when wash/dried but my old ones still look new- soft, cooling, smooth, color is still great. Not itchy or cheap feeling. Buying a new set for family.

Very nice pillowcases
Color: Haze Blue, Size: 2 Pack Standard(20"X 26")
Very pretty pillowcases. I washed them in cold water and dried them on low before using. They came out a little wrinkly but smoothed out on the pillow. The fabric is shiny and rich looking. It's not hot yet, here in Texas, but I am anticipating the coolness of these pillowcases to feel very nice. I appreciate the envelope closure. It gives it a finished look. There was no odd odor. They feel good like they'll last for a long time. I am a satisfied customer.
