I was recommended one of these by hornby. This decoder is absolutely brilliant. Easy to install the decoder and speaker in my particular locomotive. Can control on standard dcc controller or with the hornby app. I downloaded the sound files for my 67 and the variety of functions is brilliant and the sound is decent quality too out of the speaker. Better than older tts sound decoders. No need upgrade to any sound decoder that's more expensive - I am made up with this purchase and will look to buy more when I need to. Great product. ## Frequently Bought Together - Hornby R7322 HM7000-21TXS: Bluetooth® & DCC Sound Decoder (21-pin) - Hornby Accessories for 00 Gauge Track & Train Sets - Compatible with Select Hornby Model Trains, White - Hornby Hobby Train Tracks - HT8300 Straight Track Pieces x 4 168mm Track Pieces - Small Scale Model Accessories for Train, Electric Railroad Supplies with HO/OO Gauge Compatibility, Straight Tracks --- ## 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.ae/products/541330575-hornby-r7322-hm7000-21txs-bluetooth-and-dcc-sound-decoder-21](https://www.desertcart.ae/products/541330575-hornby-r7322-hm7000-21txs-bluetooth-and-dcc-sound-decoder-21) --- *Product available on Desertcart United Arab Emirates* *Store origin: AE* *Last updated: 2026-09-07*
