The Digitrax DH127P is the plug-and-play version of the Series 7 HO decoder: a 9-pin decoder already wired to an 8-pin NMRA medium plug on about 3.2 inches of harness. If your locomotive has a DCC-ready 8-pin socket, pull the dummy plug, drop this in, and you are running. The longer harness gives you room to route wires and tuck the decoder somewhere sensible. Building a DCC fleet? Browse our DCC Decoders, DCC Speakers, and DCC Accessories. Features 8-pin NMRA medium plug fitted on roughly 3.2 in. of harness - fits the great majority of DCC-ready HO locomotives with no soldering. 1.0 amp continuous, 2.0 amps peak - ample for single-motor HO diesels and steam. 2 FX7 function outputs at 200mA for directional headlights plus effects such as Mars light, ditch lights, rotary beacon and flicker. Series 7 platform with back-EMF speed stabilisation, so slow switching moves stay smooth and controlled. Longer harness than the DH127PS - easier routing, at the cost of more wire to tuck away in a tight shell. More Information Brand Digitrax Item Number DH127P Product Type DCC Mobile Decoder Scale HO Motor Current 1.0 A continuous / 2.0 A peak Function Outputs 2 x FX7, 200 mA Connection 9-pin socket with P-harness, 8-pin medium plug Harness Length Approx. 3.2 in. Series Digitrax Series 7 Sound No - motor and function decoder only Condition New FAQ DH127P or DH127PS - which one do I want?Same decoder, different harness length. The DH127P has about 3.2 in. of wire, which is easier to route in a roomy diesel hood. The DH127PS has about 1.2 in., which is the better choice when the socket sits right where the decoder has to go. Will it fit my locomotive?If the loco is advertised as DCC-ready with an 8-pin NMRA socket, yes. Pull the dummy plug out of the socket, keep it somewhere safe, and plug the decoder in with pin 1 lined up to the marked corner. Does it have sound?No. This is a motor and function decoder. For sound in HO, look at a Digitrax SDXH series decoder or a SoundTraxx unit, plus a speaker. Do I need a Digitrax command station?No. It is a standard NMRA DCC decoder and will run and program on any DCC system.

The Digitrax SDXN147A0 puts motor control, lighting and SoundFX into one N scale board decoder, and it ships with the oval speaker already matched to it. It is a drop-in for many Atlas N locomotives, which means no harness to route and no hunting for a speaker that fits - the hardest part of an N scale sound install is already solved. Building a DCC fleet? Browse our DCC Decoders, DCC Speakers, and DCC Accessories. Features Sound, motor and lighting in one N scale board - a drop-in fit for many Atlas N locomotives. 8 ohm 9 x 18 x 4mm oval speaker included, sized for N scale shells. No guesswork about what will fit. 1.0 amp continuous, 2.0 amps peak - plenty for an N scale motor. 4 FX3 function outputs at 200mA for headlights and lighting effects alongside the sound functions. SoundFX prime mover, horn and bell, with CV-adjustable volume and sound scheme. More Information Brand Digitrax Item Number SDXN147A0 Product Type DCC Sound and Motor Decoder Scale N Motor Current 1.0 A continuous / 2.0 A peak Function Outputs 4 x FX3, 200 mA Sound Yes - SoundFX Speaker Included Yes - 8 Ohm, 9 x 18 x 4 mm oval Connection Drop-in board for many Atlas N locomotives Series Digitrax Series 7 Condition New FAQ Will it fit my N scale locomotive?It is designed as a drop-in for many Atlas N models. Board decoders are shape-specific, so pull the shell and compare the factory board footprint and light positions before ordering. If it does not match, a wired N decoder is the fallback. Do I need to buy a speaker separately?No. The matched 8 ohm oval speaker is in the box. You will still get noticeably better sound if you fit it against a baffle or a sealed pocket in the shell rather than leaving it loose. Can I change the sound scheme?Yes. SoundFX schemes and volumes are set through CVs, so you can adjust horn, bell and prime mover to suit the prototype you are modelling. Do I need a Digitrax command station?Not for running - it works on any NMRA DCC system. Loading new sound files does require a Digitrax programmer.

The Digitrax DH127MT is a Series 7 HO mobile decoder built on the 21-pin MTC connector. If your locomotive has a 21MTC socket - common on European-built and many newer North American models - this drops straight in with no soldering and no harness to route. One amp continuous, two amps peak, with two FX7 function outputs at a generous 300mA. Building a DCC fleet? Browse our DCC Decoders, DCC Speakers, and DCC Accessories. Features 21-pin MTC socket (21MT) - plugs directly into any 21MTC-equipped HO locomotive, no soldering required. 1.0 amp continuous, 2.0 amps peak - comfortable for single-motor HO diesels and steam. 2 FX7 function outputs at 300mA, enough headroom for incandescent bulbs as well as LEDs, with effects like Mars light, ditch lights and beacons. Series 7 platform with back-EMF speed stabilisation for controlled slow-speed switching. Standard NMRA DCC - runs and programs on any DCC system, not just Digitrax. More Information Brand Digitrax Item Number DH127MT Product Type DCC Mobile Decoder Scale HO Motor Current 1.0 A continuous / 2.0 A peak Function Outputs 2 x FX7, 300 mA Connection 21-pin MTC (21MT) socket Series Digitrax Series 7 Sound No - motor and function decoder only Condition New FAQ How do I know if my locomotive takes a 21MTC decoder?Pull the shell and look for a 21-pin connector on the circuit board, arranged in two rows with one pin position blanked off as a key. If you see an 8-pin or 9-pin socket instead, you need a DH127P, DH127PS or DH127D. Which way round does it plug in?The blanked pin position keys the connector so it can only seat one way. Seat it square and do not force it - a bent pin is the usual cause of a decoder that will not respond. Does it have sound?No. This is a motor and function decoder. For sound in HO, look at a Digitrax SDXH series decoder or a SoundTraxx unit, plus a speaker. Do I need a Digitrax command station?No. It is a standard NMRA DCC decoder and works on any DCC system.

The Digitrax SFX007 adds prototype sound to almost anything on your layout. It is a sound only decoder with no motor control, so it works as a second decoder alongside the mobile decoder already in your locomotive, or on its own in rolling stock, inside a structure, or under the layout for stationary sound. Eight factory sound projects ship stacked on the decoder and you pick between them with CV60, so it is ready to run straight out of the package. An 8 ohm box speaker and a 330uF capacitor are included, and the Digitrax Easy Connect harness needs only two wires to the track. Smart Power Management keeps the decoder from tripping your booster or programmer during setup. Specifications Brand Digitrax Item Number SFX007 Decoder Type Sound only, no motor control Sound System Digitrax SoundFX v3+ Sound Memory 16 Megabit onboard Audio Up to 8 simultaneous voices, customizable 16, 12 or 8 bit Speaker Included 8 Ohm box speaker, 16 x 26 x 9 mm, 6 pin plug Capacitor 330uF, included Track Connection Digitrax Easy Connect harness, 2 wires Addressing 2 digit and 4 digit Programming Direct and Operations mode Scale All scales Compliance DCC compatible, FCC Part 15 Class B UPC 652667200653 Features Sound only design pairs with the non sound decoder already in a locomotive, so you keep the motor control you have and add sound on top. Eight factory stacked sound projects: AC4400CW, ATSF 3751, C-420, GP7, GP38-2, SD40-2, SD70MAC and UP3985. Diesel and steam are both covered. CV60 selects which of the eight projects is active. No programming track gymnastics and no download needed to switch. Reloadable with any SoundFX 8 bit or 16 bit project using the Digitrax Sound Programmer and the SoundLoader app. Compact enough to sit alongside an existing decoder in many locomotives. Use custom sounds to give rolling stock a voice, or to drive stationary and under layout sound. Smart Power Management stops the booster and programmer shutdowns that plague high draw sound decoders. Speaker and capacitor are in the package, so there is nothing else to buy to hear it run. Frequently Asked Questions Does the SFX007 control the motor?No. It is sound only. Keep the mobile decoder already in the locomotive for motor and lighting control, and let the SFX007 handle sound as a second decoder on the same address. Can I use it as an add on to a Series 5 decoder like the old SFX006?No. Digitrax states the SFX007 is not compatible as a Series 5 add on the way the SFX006 was. It installs as an independent second decoder instead. What scale is it for?All scales. The decoder and the included box speaker are sized to fit HO and larger comfortably, and the harness wiring suits O, S and G installs just as well. Do I need to buy a speaker?No. The 8 ohm 16 x 26 x 9 mm box speaker is included and plugs into the 6 pin connector, along with a 330uF capacitor. Can I change the sound later?Yes. CV60 switches between the eight projects already on board, and you can overwrite the decoder with any SoundFX project using the Digitrax Sound Programmer and SoundLoader. Will it work in rolling stock or a building?Yes. Digitrax builds this decoder for exactly that. Load a custom project and use it for a caboose, a stock car, a sawmill, or any under layout sound scene.
