SoundTraxx 852005 | DCC Mobile Decoder MC1H104P21

The SoundTraxx 852005 is the MC1H104P21 DCC mobile decoder — a motor and lighting decoder without sound, for HO scale locomotives. It is rated 1 amp and connects by 21-pin nmra connector, plugs into the factory pcb.

As an MC1 series decoder it operates on DCC only — it needs a command station and will not run on a plain DC power pack. Motor control is SoundTraxx Hyperdrive.

• DCC operation — requires a DCC command station

• Rule 17 or directional lighting control, grade-crossing timers, adjustable flash rate and LED brightness correction
• Hyperdrive motor control for smooth low-speed running
• NMRA DCC compliant, made in Durango, Colorado

Does this make engine sound?
No. Mobile decoders drive the motor and lights only. For sound, choose a Tsunami2, Blunami or Econami sound decoder.

Will it run on my DC power pack?
No. This is an MC1 series decoder and is DCC only — it needs a command station. If you need DC too, choose an MC2 series decoder such as the 852002 or 852003.
