The MX648 sound decoder from Zimo shares all the same benefits as the larger MX645/MX644/MX646 decoders, but without the built-in energy storage connections, and with 6 AUX function outputs. The advantage is that the MX648 is much smaller, so great for restricted spaces, including many N gauge models, and will work well with most modern OO models too.

The MX648 can have a stay-alive capacitor added, but it must go through SPEIKCOMP circuitry.
