How to install Hornby Triplex sound in the Class 56

A new breed of Bluetooth sound chip is here with the arrival of Hornby’s Triplex Sound decoders. MIKE WILD installs the 8-pin variant in a Hornby Class 56 and explains the set up process step by step.

HORNBY HAS stepped up the game in digital control with the introduction of its Triplex Sound Bluetooth and sound decoders. We took our first look at these new chips in HM191 and for this feature we are following the full installation and set up process from start to finish.

The Triplex Sound chips are available in 21-pin, 8-pin and Next18 formats and can be installed in any brand of locomotives. The only caveat is that the Next18 decoder size is larger than other sound chips and won’t fit into all locomotives.

Above: Hornby’s new Bluetooth Triplex sound chips are a revolution in digital technology and simple to install and manage. Class 56 56103 Stora, now fitted with Triplex Sound, takes charge of a fuel oil train. Watch our sound demonstration video below.
