Version History

Since 7/8/23 the downloadable data sheet and online data matches the screen printing on the amplifier for LPF and subsonic filter. There are detail but not significant differences between the lab report (and hence the paper data sheet included with the amplifier in the box in relation to these 2 fields.)
