I've just acquired an XH-A1S to supliment a non-S model. Apart from the loss of the oh-so-useful stand-by switch beside the stop/start button, all the changes appear to be improvements.

However, I cannot find anything in the manual to tell me what the function of the "audio level lock" switch, below the audio level dials, is. I've searched this forum for "audio level lock", but found nothing. can someone enlighten me, please?

TIA

Hi Mark,

The switch locks the audio level pots, thereby preventing unintentional
changes in levels caused by inadvertent handling. Hope this helps,

Thanks Chris. Nice and simple, then.
