Emu Filter differences - fan noise - HD removal

Emu Filter differences - fan noise - HD removal

2005-12-17 by grenham7651

I've just imported some EMAX II samples into the Esynth, rev 4.62, 
and found some sounds haven't translated too well.
Seems to be the filter settings that suffer. The Esynth's 4 pole 
filter and Q settings, looking like they translated well, with a 
precise frequency rather than a 0-120 Fc number, sounded thinner, 
lacking weight and bottom end. Although there's a good selection of 
filters, I haven't been able to exactly recreate the original sound.
Any theories on this ?

Has anybody been bothered by the noise of the Esynth rack's fan ? 
It's not just the whirring but the whining as well. I replaced mine 
with a Papst but didn't get much improvement, so have disconnected 
it.  There's a lot of free space inside and ventilation on the power 
supply casing so I'm hoping it should be OK. 

One final question, regarding removing or disconnecting Emax 1´s hard 
disk, is it an easy job disconnecting it internally ? 
Have other users been bothered about the output level of HD noise ?
I have an external zip that I prefer to use but will I have to boot 
from a floppy as the zip is configured for scsi 5 or 6 only.

regards
Lyn

Booting from floppy is not the end of it, the emax then accesses the floppy to perform different functions.  I could never disconnect the HD in mine for that reason alone, it would slow me down more.

The noise from the HD is loud, but it varies between units (and perhaps HD's?) mine's not the loudest I've heard but not much softer.

I think just removing power to it should do it.  maybe remove the internal scsi cable as well, but that might not be necessary.

I like the external zip a lot too.  maybe there's a way to get a internal zip drive in an enclosure to make it external that then can be set to SCSI ID 0 ??

The Emax II has 2 pole filters, so that may be causing some of the difference 
you are hearing. 2 pole resonance sounds noticeably different to 4 pole 
resonance. The 39kHz output sampling rate on the Emax II may also play a part.

The hard drive I have is a Quantum Pro 50mb and while acoustically 
it's not too bad, the problem
is the transmitted output noise. Turning the monitors up reveals 
this, more so than any other
equipment I have.
It's down to the whirr and whine.
It's connected via a plate to the outside casing and after 
disconnecting the power to it
the whirr ceased, but not the whining.
I then disconnected the scsi cable and lifted it outside the case. 
The whining stopped then
as well.
It seems the whine is caused by contact of the plate to the outside 
casing.
So, some insulation tape and rubber grommets cured that.
I haven't found a way to cure the whirr but it's definetely more 
acceptable now.

As regards the filter, yes, the 2 pole sounds a lot closer than the 
defaulted 4 pole.I compared it with the original source from the Emax
as well and the Esynth translation is better than the Emax II, 
strange !
