The other function is to repeat IRinputs from DA outputs. This unit burns itself out when an IR sensoris exposed to IR noise. - - It's one thing for it to not work in the presence of noise - I can see that - but it burns out! - That's a design error. Tech support insulated me from engineering instead of allowing meto work with them, which I was happy to do. (I'm an electrical engineer)Instead, they gave me silly things to do like installing a surge suppressor and another power supply.They never acknowledged the problem, but gave a 'modified' unit to try. Beware if you depend on the IR function. This might be a company that just markets devices that are designed offshore and don't have significant internal technical competence. ### ⭐⭐⭐⭐⭐ CHANNEL PLUS DA-550HHR *by J***N on June 4, 2011* The CHANNEL PLUS DA-550HHR Video Distribution Panel with I/R work's great, does what it says I like the fact that it combines two channel modulators on to one cable. ### ⭐ Only lasted three days. *by D***D on February 5, 2014* This is the second unit I have tried. The first unit lasted a couple of years before failing. The new repalcement unit only last at most three days. The new replacement unit will not reset nor power up, even with every input/output disconnected. Installed a new Electroline drop amp and now have the best picture I have ever had. I used a 3-way low loss splitter to combine the three inputs, two modulated and one antenna. I put the antenna in the low loss port and then added the other two modulated signals. Feed that combined signal to the new drop amp with 8 outputs. Wow, works great. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sn/products/8090022-channel-plus-linear-da-550hhr-channelplus-high-headroom-rf-distribution](https://www.desertcart.sn/products/8090022-channel-plus-linear-da-550hhr-channelplus-high-headroom-rf-distribution) --- *Product available on Desertcart Senegal* *Store origin: SN* *Last updated: 2026-05-30*
