This is a standard Hornby next18 HM7000 sound decoder, but with a plux16 adapter allowing it to be used in models with a Plux22 socket, such as recent Bachmann models. It has a few limitations though. You might lose some lighting functions, as you only have access to directional lights and aux1 and aux2. You also need to be mindful of the speaker impedance. You must only use an 8 ohm speaker, if your model has two built in speakers, one has to be removed before you fit the decoder. Don't use any additional speakers unless you remove all the speakers built into the model.
Part of the innovative HM7000 range, the Next18-pin Bluetooth® and DCC sound decoder is ready to plug into locomotives featuring a Next18 (NEM662*) socket. The Next18 socket is found in modern Hornby locos, many other locomotives in 00, H0 and some smaller scale locomotives.
The decoder is designed to supply 500mA continuous load to the main motor and a peak demand of 1,000mA, making it highly suitable for most 00 and H0 scale locos.
Also included are assorted 'speaker enclosures'. When installing the speaker inside your locomotive, picking the largest enclosure which will fit inside the loco body will give the best sound reproduction from your speaker.
Download your first set of sounds and install them via the HM7000 app - you can download different sound packs and change those on your decoder later if you wish.
*please note, this decoder does not meet NEM662 space requirements. Please check the locomotive has sufficient space prior to purchasing.
Choose from the standard sugarcube speaker kit which requires assembly, or choose one of the free upgrades which comes with the plug to connect it to the decoder.
The sound files are all free on the Hornby HM DCC app for Apple or Android and you can load them on at home in around 20 minutes, but if you would prefer to have the sound already installed we offer that service here.
