View Full Version : 1/4" versus 1/8" jacks

November 21st 03, 08:50 PM
I'm doing some voice recording for my flash animations and I'm using a shure
sm57 with a midiman mic preamp. I used to feed the 1/4" line out from my mic
preamp to the 1/4" input on my soundblaster's LiveDrive unit (which is
basically an extension of the sound card with 1/4" inputs) -- the problem is
that I just started using it again after about a year and a half and for
some reason can't get it to work. The computer won't recognize it--no matter
how many times I uninstall the drivers and in the device manager and then
reinstall it. Enough rambling on, I went to radio shack today and picked up
a 1/4" stereo to 1/8" stereo adapter and just plugged that right into the
card instead-works fine, but since I have nothing to compare it to, I'm not
sure if it sounds worse than if I had been using the 1/4" ins.

In short, is there that much of a difference between 1/4" and 1/8",
particularly when the cable itself is a 1/4" one; only the plug (1/4" - 1/8"
adapter) is 1/8"? Thanks.

There is no difference in quality.

The jack and plug type should not change the quality at all.

great thanks. Just curious--what if I had been using a thinner (made for
1/8" plugs) cable, as opposed to just the jack? Would that have affected the
sound?

if the cable quality is good and run is short it should not matter. one
thing you may want to use a 1/4" to 1/8" cord instead of just a metal
adaptor. it puts a lot of stress on the 1/8" plug and jack.

The shielding makes more of a difference. Often the thickness of the cable
is mostly due to quality of the shielding.

Going into a Soundblaster, cable quality is not a factor at all.

It won't sound any different until it falls out, or makes bad contact,
which it eventually will - just like the other one.

Every designer who ever put a 1/8" jack on a piece of equipment should
have a mini plug shoved up his ass with 120 VAC across two of the
terminals. Maybe if he's lucky it won't make good contact.

Equipment should be big enough to have robust connectors to the
outside world. If it has to be small, there are better (though
admittedly more expensive) connectors that could be used.

I wouldn't put it QUITE as strongly as that! But you'll have a
pleasant surprise when you lay out surprisingly little cash on a
mixing board and interface to the SB Line in rather than it's crappy
mic in.

The difference is that 1/8" jacks fail, and 1/4" jacks (long frame
ones anyway) don't. 1/8" jacks fail constantly and should not be
trusted.

The big problems with 1/8" jacks is that they are delicate and fussy. If you
have a good 1/8 jack and get the plug seated well, the technical performance
for line-level signals is the same as the equivalent 1/4" jack.

IME sticking a 1/4" to 1/8" adaptor plug into an 1/8" jack just exasperates
the already undesirable durability situation. An adaptor cable should be
used instead, because it avoids putting an undue mechanical load on the
jack. 1/8" jacks work best with relatively thin cables. For line-level
signals over a distance of 3 feet or less, thin cables aren't a problem.

Thanks everyone for your advice. I see what some of you mean about the
weight from that extra adapter putting too much stress on the connection.
What I need though is a cable with 2x 1/4" monos on one end and 1x 1/8"
stereo on the other. This particular kind of cable is not easy to find. It
is easy to find y-cables with like-size jacks on both ends but not unlike,
it would seem. I guess a good way to go would be to either to use my 1/8"
male to male stereo cable and connect it to a y-adapter with a stereo 1/8"
jack and 2x 1/4" mono plugs, although I haven't begun to look for this combo
yet either. Since I have soldering skills, another thing I could do is to
just buy the connectors and make my own custom cables.

Hosa makes these in 3 and 10 foot length, CMP-153 and CMP-159.

What is easy to find is a cable with 1 x 1/8" stereo on one end and 2 x RCA
on the other. Add RCA-to-1/4 mono adaptors, and you're stylin. Since the
adaptors are on the robust 1/4" end, durability is rarely an issue.

That's a good idea--in fact, I even have that cable already! All I would
need are the 2x 1/4" mono adapters. Yeah, I might do it this way.

Hosa's are very unreliable in my experience. In general anything with
molded ends are suspect.

What is easier to find is a stereo 1/8"-male-to-stereo-1/4" female adapter,
and an "insert cable" ( 1/4" stereo male to 2 mono 1/4" male ).

If you'll route this to a patchbay, you'll be able to get to them more easily
and not plug/unplug the 1/8" end quite so often.

Depends on the application. If one end goes to the computer and the
other to a patchbay, it'll rarely move.

This being said, I built cables ( and the 1/8" end was painful to
solder ).

That's what you have to do sometimes. However, cables with a stereo
mini plug on one end and two RCA plugs on the other are very common.
If you want an off-the-shelf solution, you can buy one of those and
two RCA-1/4" adapters. Those adapters aren't any heavier than a
standard 1/4" phone plug, so there's no worry about excess strain on
the jacks like there is when adapting a mini jack to a larger plug.

But you can buy such premade cables using quality cable and connectors.
More money than Hosa but think of it as insurance. Bad cables always
seem to go out at the most inopportune moment. Murphy's law.

I use to use a Shure sm57 for voice recordings, I switched to an Octava
MK319 (only 99 bux at git center on sale) and it is a WORLD of
difference for voice-over and foley stuff. Very sensitive and very
cheap. Test it in the store though, I have heard that there are a few
bad ones floating around. I love mine. I have it going into a cheap
Bellari pre-amp and then into a cheap Behringer compressor.

Yes they are but he cant change the socket , so in this case it should be
okay, unless he wants to make a new lead with the cannon on one end and an
1/8 on the other.
