Description

RDL SF-NP35E 35W Dante to 70/100V Mono Audio AmplifierThe SF NP35E is an audio power amplifier that converts one Dante network audio channel to a 70 V or 100 V constant voltage amplified output. The output provides 35 watts for a network digital audio level of 0 dBFS. Special software is not required to configure the module. The SF NP35E is equipped to operate from a PoE++ enabled network switch. The SF NP35E may be powered from an external 24 Vdc power supply, available separately. If a PoE++ powered

The SF-NP35E is an audio power amplifier that converts one Dante network audio channel to a 70 V or 100 V constant voltage amplified output. The output provides 35 watts for a network digital audio level of 0 dBFS. Special software is not required to configure the module.

The SF-NP35E is equipped to operate from a PoE++ enabled network switch. The SF-NP35E may be powered from an external 24 Vdc power supply, available separately.

If a PoE++ powered device instantaneously demands excessive power from a PoE++ port, that port can shut off its output voltage, causing a prolonged disruption of the device operation. The SF-NP35E monitors the amplifier power and limits the current to protect the PoE++ port against shutting down even during extreme feedback or square wave modulation conditions. A red rear-panel PORT PROTECT LED flashes when the SF-NP35E reduces power consumption to prevent shutdown of the PoE++ port voltage.

The SF-NP35E is equipped with an internal VCA for setting the output level. A detachable terminal block provides for the connection of an external 10 KΩ potentiometer or a 0 to 10 Vdc control voltage. The amplifier gain remains at maximum when the VCA input terminal is not connected. RDL remote controls are available to provide single-turn, multi-turn (rotary encoder) or pushbutton (ramp or fixed level selection) user level control. VCA control insures long term noise-free level adjustment.

The module is equipped with both thermal and output short-circuit protection. The high-efficiency Class D output stage produces minimal heat for all levels of expected voice or music modulation. An LED MUTE indicator glows yellow when the output is muted. Valid synchronization to the Dante network is indicated by a green LED visible from the front of the unit.

The SF-NP35E is constructed in a durable, professional all-metal enclosure suitable for free-standing, surface-mounted or rack-mounted operation. This full-featured SYSFLEX® product is engineered and manufactured in the U.S.A for continuous duty in demanding installations. The versatility of SYSFLEX® products adds enormous flexibility in the design and installation of professional A/V systems.

My 90 lb. Pitbull's All-Time Fave Toy
Size: Large, Color: Coral, Size: Large, Color: Coral
I ordered a plethora of new toys for Bruce to keep him occupied while I am working remotely from home. Poor guy gets so bored while I'm stuck in front of my computer 8+ hours a day. All the other toys are animated, but this one is just a big floppy chewy squeaky toy. Bruce quickly lost interest in all the other chirping, hopping, and twirling toys and fell in love with "Diny". When I opened Diny and gave it to Bruce, he had the elated and surprised look of a 3 yr old at Christmas. And he stayed that happy for hours, and then each time he picked up Diny to play. Diny became his go-to toy over all others (and there are many!). It is well made out of durable fabric, and they did not stuff it full of kapoc (I hate kapoc in dogs toys!). And it is delightfully low-tech. Normally he tears a squeaky toy apart as soon as he can isolate the squeaky mechanism. But cleverly, the squeaky box is loose in the long belly so it moves from one end to the other as the toy is handled. That made it difficult for Bruce to locate it. The toy remained in good condition for 2 weeks of near constant attention by Bruce. But yesterday he zeroed in on the squeaky box and ripped Diny to shreds. I was sad to see Diny go so soon. But boy-howdy was Bruce happy with it. I'm gonna buy another because we liked it so much. And so did I : )

This is one “under the radar” gem!!
Size: Large, Color: Coral
This is one “under the radar” gem!! Very strong internal squeaker and way tougher than it looks. My big 125lb Shepard-Husky mix gave it heck, then made it his new buddy. He’ll occasionally give it the business but on the whole, it’s surprisingly tough and my big boy loves it. Nice price!!

Cute but small
Size: Large, Color: Skinny Green
Cute stuffy and has not yet ripped. While my dogs plays with it, the toy is a bit small for him. For reference he is 120lbs.

My Puppy Loves this Indestructible Dragon
Size: Large, Color: Pink, Size: Large, Color: Pink
My puppy (8 month old black lab mix) loves, loves, loves her dragon. She has had it for 2 months now. It is one of her favorites and gets daily rough play time. It's her go-to toy for fetch and tug games, as well as just general mouthy play. The squeaker gave out after about 4 weeks, but she would binge squeak for prolonged periods (kind of like chomping on gum) so it was almost a blessing when it went silent. She still chomps on it, but at least now I don't have to hear it. Other than the fact that it's a little grungy and bedraggled from so much loving, it is still in amazing shape. The seams and fur are all still intact. There are no visible holes, rips, or weak spots. I love Chew Guard Technology. This dragon replaced her goDog Iguana (from PetSmart) that developed a tear in the fur after about 4 months of heavy use. (It was superficial, just the outer fur layer and not the innards, but we disposed of it before she could eat more fur.) She can be pretty rough on her toys and I can never predict if any given toy will last minutes or months. The goDog stuffies definitely fall into the "months" category, even with rough daily use. Edit: The dragon lasted about 6 months of intensive, hard play before it developed a small tear in the fur. I patched it a couple times, but once my pup discovers a weak spot, it's the kiss of death for any stuffed item. We had to dispose of the dragon (so sad) to keep her from eating any more of the fur. We replaced the dragon with the goDog Chameleon, which is still going strong. I think we will go back to the dragon for our next toy because it's just so darned cute. We gave the dragon to my niece for her golden retriever puppy who is very chew-happy. That dragon is also doing well. You've just gotta love that chew-guard technology. This is one tough toy.
