Kobra11 Posted January 23, 2013 Posted January 23, 2013 Hi all, During band practice im noticing my vu meter on my EB15 is constantly in the red, sometimes even off the scale! is there any problem with this or should i just ignore it? I know my playing isnt off the scale Quote
Kobra11 Posted January 23, 2013 Author Posted January 23, 2013 Tried that, didnt make a whole lot of difference, it was in the 9 oclock position to begin with Quote
nottswarwick Posted January 23, 2013 Posted January 23, 2013 oh, I'm out then... did it sound ok? Quote
Protium Posted January 23, 2013 Posted January 23, 2013 Does it have 2 input sockets (high and low)? Try the other socket as your input signal might be too loud, I can never remember which one you use for a hot signal Quote
barkin Posted January 23, 2013 Posted January 23, 2013 Active/passive bass? Does the amp have two different inputs? Despite what the needle's doing, does it sound OK? Quote
Kobra11 Posted January 23, 2013 Author Posted January 23, 2013 Theres 2 inputs active and passive, im using a passive bass (Yamaha RBX170) through the passive input Sounds fine, just worried it might damage it long term Quote

RandomBass Posted January 24, 2013 Posted January 24, 2013 Yeah try the active input and see if this calms things down. You're not using any pedals with boost are you? I used to use an RBX170 with an EB combo, and never had this. Does it sound ok? Not distorted? What are your tone settings etc? These will also affect the VU meter. Cheers Geoff Quote

[/quote] +1. Some passive basses can have very high output. And conversely some active basses have a low output. Quote

[/quote] Yep, if they all are at three o'clock its IN THEORY the same as raising the gain on your signal, so you would get the same effect using the knobs at 12oclock and raising the gain a bit. I repeat, this is theoreticaly speaking. When using EQ the main thing to keep in mind is to have all settings balanced around the 0dB position: Read pages 7, 8 and 9 of this manual: [url="http://www.britishaudioservice.com/inst/SMX.PDF"]http://www.britishaudioservice.com/inst/SMX.PDF[/url] The chapter called "Using the Graphic Equalizer". I know you don't have a graph EQ on your amp but the main idea is the same Quote
geddeeee Posted January 24, 2013 Posted January 24, 2013 The rotary dial displays the ouput watts, not input gain.... Quote

RandomBass Posted January 25, 2013 Posted January 25, 2013 Having the Bass on 3 oclock is the main problem - way too much! Try all eq flat to start with, and take it from there. The VU meter measures the preamp signal going to the Output control, so will be affected by the settings of the eq section, hence the big swing of the needle Quote
JapanAxe Posted January 25, 2013 Posted January 25, 2013 I'm a former Ashdown owner. IMO the VU meter is a gimmick There, I've said it! Quote
geddeeee Posted January 25, 2013 Posted January 25, 2013 Spot on... Definitely a gimmick. As long as the amp doesn't sound distorted. Looks nice though!!! Quote
Kobra11 Posted January 28, 2013 Author Posted January 28, 2013 Got a chance yesterday at band practice to try out the things you guys said and guess what?.... It worked! Thanks for all the help guys, much appreciated Quote
Mr Fretbuzz Posted January 28, 2013 Posted January 28, 2013 The bass boost button on my mag 300 has the same effect and it's made worse if the bass is on 3 o clock. I run mine with all levels about 12 o clock , input at 3 o clock and boost off.... Only occasionally does the signal go in the red then ... To my newbie mind it seems to be the low bass signal to blame Quote
loushort Posted January 28, 2013 Posted January 28, 2013 had the needle not move at all and the bass blasting thru my Ashdown Mag combo 1x15 eq all set to 12 o'clock Quote
