The ESU 58429 LokSound V5 DCC 21MTC NEM660 decoder features a 21 - Pin socket, measuring 30mm x 15.5mm (1.189' x 0.609'). It's ready for programming, but no programming is included. If you want the sound file programmed, just add the sound file number or locomotive type (like GP38) in the 'add order note' in your cart's lower - left corner. Yankeedabbler will load the sound file for free. You can view the ESU Sound Library for North American and AUS files at https://projects.esu.eu/projectoverviews/18. We can load any ESU sound file, just tell us the number or locomotive type. You can also buy a LokProgrammer (stock number 53452), though it's not always necessary as decoders can come pre - loaded with sound files and CV changes can be made using control systems. This decoder is for HO gauge and fits HO scale locomotives with a 21 Pin MTC Motherboard, such as Intermountain, Bowser, Rapido, and Athearn Genesis units released after late 2018. Check your locomotive manual to pick the right decoder. The decoder has 'Full Throttle' features to compensate for what it can't detect about the load. It supports all DCC programming modes and can read CV values on the main with a RailCom® - supporting command station. It works with Märklin®, ZIMO®, and Lenz® braking systems, and can brake with DCC or DC. It's suitable for analog DC, AC, and DCC command control. The LokSound V5 can play up to 10 channels simultaneously, with high - quality audio and a large sound memory. It has adjustable sound volume and flexible sound simulation. It also has multiple amplified outputs for lighting and more outputs for servos or logic control. The motor control provides up to 1.5A current, with a variable PWM frequency for silent operation and an 'Auto - Tune' function for perfect motor calibration.

Using this decoder is straightforward. First, check if your HO scale locomotive has a 21 Pin MTC Motherboard. If it does, you're good to go. If you want the decoder pre - programmed with a sound file, add the relevant details in the 'add order note' when you place your order. If not, you'll need to program it yourself later. You can either use a LokProgrammer or make CV changes with a compatible control system. When it comes to operation, the decoder supports different braking systems and programming modes. Just make sure your command station supports RailCom® if you want to read CV values on the main. For sound, enjoy the high - quality audio with adjustable volume. You can fine - tune the sound to match your needs. As for motor control, the variable PWM frequency will keep things quiet. Remember to use the 'Auto - Tune' function to make the decoder work perfectly with your motor. Maintenance is easy. Keep it clean and dry. Avoid exposing it to extreme temperatures or moisture. If you have any issues, refer to your locomotive manual or contact our support team.
