 Cabling 101 
 
Cables are a crucial (and often overlooked) part of  a studio.  Many 
beginners run into problems because they use inappropriate or 
poor quality cabling to connect their gear and their recordings 
suffer as a result.  Don’t let this happen to you!  Use the following 
guidelines to maximize your sound quality: 
 
1.  Use balanced cabling wherever possible – The IO|14 and 
IO|26 are fully balanced recording devices that will give you 
the best sound quality when using “balanced” cabling 
wherever possible.  Technically speaking, balanced cables 
carry your signal over three conductors (known as “hot” 
“cold” and “ground) as opposed to “unbalanced” cables 
which only have two conductors (known as “hot” and 
“ground”).  Because of  this design difference, balanced 
cables pick up much less radio frequency (RF) and 
electromagnetic (EM) noise.  Musically speaking, this means 
you’ll have much less unwanted humming, hissing, and 
buzzing noises in your recordings. 
 
2.  Minimize Cable Length – As your cable length increases, so 
does your signal’s susceptibility to unwanted noise.  Try to 
minimize your cable runs as much as possible to preserve 
sound quality.  Don’t sweat over minor differences in length 
(i.e., using 20’ of  cable when you only need 15’), but definitely 
don’t use a 100 ft. cable if  all you need is 10 ft.! 
 
3.  Use High Quality Cables – Not all cables are the same!  
Try to use well constructed, high-quality cables whenever 
possible.  Two cables may look the same on the outside, but a 
high quality cable will have better shielding and soldering on 
its connectors.  This means a good cable will perform better 
and last much longer than a cheap one. 
 
4.  Keep ‘em separated! – Try to keep your audio cables and 
power cables separate from each other.  Power cables tend to 
emit lots of  electromagnetic noise and if  you bunch all of  
your cables together to make them look tidy, you’re increasing 
the noise that is picked up by your audio cables.  Group your 
cables in two bunches if  possible (i.e., an “audio” group and 
an “other” group) and keep these groups separate.  Even a 
few inches between the two groups will substantially cut 
down on noise.  If  your power and audio cables need to cross 
paths, have them do so at 90 degree angles to minimize 
contact.
