Best DCC decoders
« on: February 10, 2018, 07:11:30 pm »
Hi all,
I am starting to look at converting rolling stock to DCC and I have seen posts where certain decoders hum or buzz.  What is your advice on DCC decoders, both standard and sound?

Regards

Ian

Humming and buzzing was commonplace in early decoders (20+ years ago) where the PWM driving the motor was a low frequency. These days most decoders use higher frequencies 16kHz or higher and is selectable to suit the type of motor.

People have different favourite brands of decoder which they've found work well for them, the old adage "you get what you pay for" tends to apply.

An exception to this are the Zimo 6 pin (MX622N) and Bachmann (36-568) Next18 decoder which are both quality Zimo decoders but £20 or less

Quite right, and as they can operate at 40kHz no problem with buzzing.

ZIMO changed the game for economical decoders last year - now you can choose low price and top quality in the same decoder.

I use a variety of makes and types; Zimo, CT, Digitrax, Soundtraxx, Lenz and TCS.
Sometimes try two or three different makes in a loco to get performance I like.

The 568 is the 6-pin one, the Next18 one is 36-567. Both are Zimo, although the 36-568 is more expensive than the Zimo branded identical chip. The 36-558A is alright as a cheap decoder, but nowadays prices are so close to the Zimo version it’s not really worthwhile.

Really for 6-pin decoders there’s no reason whatsoever to buy anything but the Zimo MX622N. It’s an absolute steal at £20. I bought 20 Of them from Digitrains and got a small discount. I use Digitrax DZ126s for anything with solder tabs on the PCB and Laisdcc ones for function use. All are fine, but i do ensure I turn off DC compatibility on the Digitrax ones, as a short often ends up in a runaway.
