Good god no. Will this mean distorted announcements like the 170's?
I vaguely remember someone on this thread (can't remember who, sorry) saying the distortion on the 170s wasn't the permanent state of affairs but a fault that was being resolved.
This is different to the Sprinters and 323s, where even before TrainFX was fitted, announcements by the guard sounded muffled. TrainFX just plays its announcements through whatever PA equipment is already fitted to the train*, so of course the auto announcements also sound muffled and presumably will do forever unless the PA system is completely replaced with a modern one.
* This had the slightly strange consequence of the auto announcements occasionally being heard in Pacers - which, apart from the one-off Porterbrook "144e" one, were never fitted with TrainFX - when they were coupled to Sprinters that were fitted. If I recall correctly, this lead to a policy that the auto announcements should only be switched on if all units in the train were fitted - I think it had something to do with the announcements in non-fitted units being deafeningly loud because TrainFX couldn't control the volume in them.
Sorry if any of this is incorrect or I've misunderstood.
