PESTinUK Posted September 6, 2014 Share Posted September 6, 2014 I bought a 2nd hand Class 22 (with a sound chip fitted) from a dealer at a swap-meet. There was no paperwork with it, and I don't know how to adjust the sound volume. I tried adjusting CV63 to a value of 64, but if anything,it seemed quieter. Can anyone identify the chip from the photo, and tell me how to adjust the volume please? Link to post Share on other sites More sharing options...
kevpeo Posted September 6, 2014 Share Posted September 6, 2014 I'm not clever enough to id the decoder from the photo, but if it is an ESU v4 the volume goes up to 192. So you may have turned it down by entering 63! Kev. Link to post Share on other sites More sharing options...
scoomby Posted September 6, 2014 Share Posted September 6, 2014 Looks like an ESU V4 from the photo Link to post Share on other sites More sharing options...

PESTinUK Posted September 8, 2014 Author Share Posted September 8, 2014 Yep .... that was it. I've got so used to Bachmann/Hornby sound locos having 63 (or is it 64?) as their top value, I thought that was standard across all decoders. Thanks for your help guys.

RMweb Gold Phil Bullock Posted September 8, 2014 RMweb Gold Share Posted September 8, 2014 Also looks to me like it might have the wrong speaker in it - is that just a round one? This is the one designed to mount in the clips in the chassis http://www.dccsupplies.com/shop/product_info.php?cPath=98_108_778&products_id=3543 Should sound something like this - 7 mins in Cheers Phil Link to post Share on other sites More sharing options...
charliepetty Posted September 18, 2014 Share Posted September 18, 2014 Now then, low sound from a 23mm Speaker? Have you sealed the speaker, IE all the holes in the black housing, use tacky wax or similar. The speaker housing has to be air tight to work correctly, also experiment with the speaker facing upward and downward, select which way sound the best. Also make sure 'NOTHING' is touching the top black area on the speaker, as this vibrates for good sounds, a better speaker (Bass Reflex) can be had if all this fails. PM Me if you want a cheap 4 Ohm Bass Reflex speaker. Charlie Link to post Share on other sites More sharing options...
