The D SERIES-HA1A is a two pair receiver and audio headphone amplifier compatible with RDL Format A twisted pair products. Each -HA1A receives stereo audio and 24 Vdc power through a rear-panel RJ45 jack fed from a Format-A sender. The left and right audio signals received on pairs B and C of the twisted pair cable are amplified and fed to the left and right channels of the output 3.5 mm Mini-jack.

The front panel provides the headphone output jack and a single-turn user volume control. There are no illuminated indicators that could be distracting in dark locations, such as a hotel room. The audio input circuits feature very high common mode rejection and a high quality stereo headphone amplifier for superior audio fidelity and low-noise performance.

The -HA1A is ideally suited to guest room installations with bedside and restroom listening stations. The input is fully compatible with all RDL Format-A senders.

The -HA1A is equipped with two Format-A RJ45 jacks. Either jack may be used as the input. The other RJ45 may be used to connect an additional -HA1A or other Format-A receiver.

Installation is simple and economical. Standard twisted pair cable is used to connect a Format A sender to the -HA1A.

RDL FORMAT-A features superior audio performance that rivals or exceeds shielded wiring. Design simplicity, ease of installation, unsurpassed flexibility, automatic fused power, exceptional hum rejection, low noise, and low distortion provide designers and installers the optimum choice in economical twisted pair products.

Grey fit Great~ Pink too Big (Ordered same size)
This was Very unusual to have ordered 2 pair of shoes in SAME Size, one color (Grey) fit Great!! However the Pink pair were HUGE & even my daughter tried to slide right in them but they were “BOAT” shoes on her too! I love the Grey (that fit😅) as wear when I’m cleaning &/Or dressing up to go out. The Grey is very versatile in what you can wear with these. The #1 thing I LOVE that sounds Corny Ah??.. I mop my floors & I can walk across without busting my 🍑!! I walk on Water in floor & don’t even slide nor have I had to catch a cabinet on my way down!! Love these shoes soo much. Don’t know what Co but I want other colors!! Great Buy so I think I’ll do it again & buy another pair once I receive return. I truly don’t know what to tell others?.. Maybe something like: “if Pink is your Fav Color & U feel need for some pink slides than order couple sizes smaller?🤷🏼‍♀️ I ordered pink for my 21 yr old daughter who can pull off wearing any pink. shoes. I literally couldn’t take watching her wear these Pink ‘Oversized’ Boat shoes like she stole them or someone felt sorry for her looking poor & handed her the shoes off their feet.. I just RETURNED them & now have tell her to pick a color & I’ll buy her another pair (not pink). My Grey ones look Great& feel even better!! So many have asked Where I bought & never seen before. These are VERY Comfortable!! I wear them all day Into night. I need to order more colors & just 🤞🏼🤞🏼for size to be correct!

I love the metallic iridescent!
Why did you pick this product vs others?: I love the color and the feel but the sizing is wonky. I’m a perfect 7.5. The 7 wears like a 6-6.5 and the 8 is just a little too big. I’m keeping my 7 in the blue and I have a pair in wine/purple in 8 from a few years ago. I just won’t be running a mile in them anytime soon! LOL I love the look!

Comfortable and good traction
After being impressed by a similar (but not identical) pair of cheap slippers at an AirBnB rental, I searched out these. I bought the 44-45 size for my size 10.5 (US) feet; according to the size chart, that's supposed to fit sizes 10.5 to 11. I find that they're quite large, so that they're loose on my bare feet. In crew socks, they're OK and I use them as house slippers. As advertised, they're soft, flexible, and springy. They grip the floor quite well. They're way better than the Crocs thong-style sandals I was using as bathroom sandals before. All in all, good value for money, but if you're using them as bathroom slippers and you have normal width feet, round the size down if you're at the small end of the stated range.
