  • Made in USA

The ASK-4 #631 Audio Monitoring Kit from Louroe Electronics is a single-zone audio monitoring system with a wall-mounted mute switch designed for making a direct connection to a DVR or VCR, IP network camera, PC soundcard, video server, or other audio receiving devices that accept line level audio (0 dB @ 600?). This kit consists of an MS-1 Mute Switch, an IF-1 Interface Adapter, a Verifact A Microphone, an AD-1 Plug-in Switching AC Adapter, a 3.5mm Stereo Cable for connection to a sound card, IP network camera, or video server with stereo audio input, an RCA to 3.5mm Mono Adapter for connection to an IP camera, and a Single RCA Cable for connecting to a DVR, VCR, etc.

The IF-1 Audio Interface Adapter serves as an interconnection device between a Louroe electret condenser microphone and a DVR / VCR, computer soundcard, or an IP network camera or video server with audio. The input side features a terminal block to receive wiring from the microphone and a jack for 12VDC power input. The output side features 2 types of connections to accommodate almost all recording device audio inputs: An RCA output for connecting to a DVR / VCR with an RCA input, and a 3.5mm (mini jack) stereo output for connecting to a computer soundcard or DVR with a 3.5mm stereo audio input. The IF-1 Interface Adapter also has variable gain adjustment to prevent overdriving of the audio signal. Connector cables for output of IF-1 Interface Adapter to input of recording device are also included.

The Verifact A Microphone is an omni-directional, low-impedance, electret condenser microphone with a built-in preamp for producing line level output. It is housed in a high-impact ABS dome designed for ceiling or wall mounting. The normal pick-up pattern is approximately 15' (4.57m) from the microphone location towards all directions or within a 30' diameter circle. It is suitable for use in convenience stores, fast food restaurants, booking rooms, interrogation rooms, day care centers, sleep disorder centers, therapy labs, cashier booths, gas stations, or anyplace where CCTV cameras are installed.

The MS-1 Mute Switch is an accessory to Louroe Audio Monitoring / Audio Surveillance systems when microphone muting is required. The MS-1 contains a built-in rocker switch mounted to a single-gang stainless steel face plate. When the top part of the rocker switch is pressed IN, the rocker switch illuminates with a red light, indicating that the microphone is live and active. When the lower part of the switch is pressed IN, the illumination of the switch turns OFF, indicating that power to the microphone is cut off and the microphone is disabled. The MS-1 Mute Switch fits into a single-gang backbox (sold separately) for mounting to a wall or flat surface.

Note: Wiring Requirements: 2-conductor shielded cable, 22 gauge with a 24 gauge drain wire. Unshielded cables are not suitable for audio systems.
When this equipment is used as part of an audio monitoring system, the law requires that the public be given notice of AUDIO MONITORING ON THE PREMISES. A decal notice is included with each microphone shipped.

BNTECHGO 14 Gauge Silicone Wire Spool 40 feet Ultra Flexible High Temp 200 degrees
Size: silicone wire red 20ft and black 20ft, Color: Red and Black
I'm reworking all the interior and exterior electrical wiring, relay's, connections (body grounds as well) on my 1994 GMC K-2500, the original wire did a good service for the 25 years it has been used. I'm disabled and refuse to pay $50,000 for a new truck (it wouldn't run as well as my 1994 anyway) I was hesitant about this brand or wire, but I thought (I'm not supposed to do that) I would give them a chance thanks to the reviews. I was Extremely Pleased at the High Quality of this "Real Copper" wire, not aluminum w/ coated- COPPER !, tinned very well, the silicone insulation is real industrial grade silicone. I run all my wire inside of braided nylon sheathing and securely fasten it every 24", using adhesive lined shrink tubing over all connections- works very well with this wire, it is easy to form for tight turns, lays straight once laid out, soders excellently (the top notch tinning helps there), I now have several hundred feet of 18, 16, 14 and 12 gauge of this VERY High Quality wire (It will be used on my solar system as well now) Thanks again Amazon for another "Top Quality, First Class" product that I can have delivered to my door, 90 miles from town, AND Thanks to everyone who takes the time to review the items we all could benefit from knowing better what the strong and weak points are

Solders nice, extremely flexible maybe too flexible
Size: silicone wire red 20ft and black 20ft, Color: Red and Black
The wire solders very nicely. It's very flexible, perhaps a little too flexible. I used this wire in a couple speaker building projects. I like to put the wire in a drill and twist the wires together, it's a nice look and helps with wire management. The too flexible part makes it so the wire doesn't stay tightly twisted. To remedy that I use heat shrink at either end to at least keep the wires somewhat together.

Quality, heat resistant silicone wire for my heating coil wine bottle cutting project. I didn’t need very much, but provided me the best price and option. No regrets.
