The FSR IT-VCM Stereo Audio Volume Control Module regulates the volume of an audio component remotely. The IT-VCM can be controlled via RS-232 commands, remote switches or a remote potentiometer.
The module, powered from a standard 12VDC power supply (purchased separately), features an input gain switch to bring consumer components up to professional audio levels. It may be used effectively on integrated amplifiers especially those manufactured without a remote control. By "daisy chaining" several modules it is possible to change the volume of a single source in different rooms individually. The IT-VCM is rack-mountable.
- Balanced / unbalanced into balanced output
- Stereo in to Mono out switch
- Control volume via RS-232. A remote pot interface is also provided to allow volume control from a user provided potentiometer. The remote pot may be used with the external mute switch.
- O / +12dB consumer boost switch
- Serial activity indicators
- Power and mute indicators

Exceptional dry mouth gel
Size: 1 count (Pack of 1)
This stuff for dry mouth is amazing. I love the taste and the coating it leaves is great until I eat and then reapply. Best product I have used although more expensive than I would like.

2 tries — No actual safety seal, leaking
Size: 1 count (Pack of 1)
Update 2 weeks later — tried a replacement, hoped from a different batch. But this one was even less safe, no safety seals or even tape, and not even a product box, just a ready-to-ship baggie. Really sad, really needed this for a family member with low saliva, mouth psoriasis, and chewing-swallowing problems. No idea what to try next bc most products we have seen here have so many chemicals, sweeteners, and flavorings that are harsh for us, they would be impossible to use, worseners. We are giving up on this product, will try asking amazon for a final refund, will keep trying to find something else, and hope our family member will be able to keep eating in the meantime. Dumping unsafe product on consumers just hurts.
Bought in mid-Apr-2026, expected to love this — simple, soothing ingredients for mouth psoriasis and low saliva. But, packaging was unsafe — safety tape on outside of cap, but no actual safety seal inside, cap was simple, loose screw-on not flip-top, and gel was leaking. Amazon ai said to not use, and to request a replacement or refund. So we chatted with Amazon customer service, and they refunded. We hope a replacement from a different batch will be safer.

Good product, but Amazon cheated me.
Size: 1 Count (Pack of 2)
I have dry mouth. The gel works well for me. I use it in my night guard and it keeps my mouth hydrated all night. However, Amazon messed up the order. I only received one tube instead of the 2 I paid for. Really annoying.

Great product!
Size: 1 count (Pack of 1)
I have a history of radiation to the head and neck due to cancer. I usually use xylimelts for nighttime which are my go-to. And I can't really sleep without them. But because I use the xylimelts every night, I sometimes get sore gums. I bought this as an alternative. It works well but not as great as xylimelts. It keeps the cheeks and gums hydrated but not the tongue. I still woke up and had to have water because my tongue was dried out. It's the best backup to xylimelts I have found for overnight relief so far. Definitely going to buy again. Likely for daytime use and as a backup to xylimelts.

Ethiopian Bible paperback
Format: Paperback
It’s great with large print as described It’s nice to see the 22 books that Rome had decided no one should read But since Ethiopia was outside of their range of influence they have the whole thing I’m enjoying reading about Enoch
