Esu class 57 sound decoder

[P knowles]

Hi All 

Am after so advice I've bought a esu legomanbiffo class 57 sound chip but it has a sugar cube attached to it like in the picture but I ordered a double iPhone speaker do I keep the sugar cube on the chip then solder the iPhone to the chassis on the Bachmann class 57 in double can so help me just don't want to blow anything up cheers Paul

Hi, the sound output of the sugar cube speaker is relatively quiet and lacking in bass reproduction. I would advice removing it and only installing the double iPhone speaker. You could attach the iPhone speaker using the speaker wires of the decoder or if speaker + & - pads exist on the loco PCB, solder the wires of the iPhone speaker to these pads (remove or insulate the speaker wires of the decoder if you use the second method).

Hope this helps.

Since the iPhone speaker is already a double, I would not retain the sugar cube. I do have other installations where I have two speakers in parallel or series, depending on the overall impedance rating of the combos. current ESU LokSounds usually cope with 4 or 8 ohms, so two 4 ohm speakers need to be in series, whereas two 8 ohm speakers need to be in parallel. Watch out for LokSound Micro decoders though: I think they are rated for 8 ohm only, but check this.
