Switchcraft 318 Mini AudioStix 1-channel Passive Laptop Direct Box Reviews

1/8" TRS-M to XLR-M Audio Connector With Volume Control, Ground Lift, and Transformer Isolation

The Switchcraft #318 Mini AudioStix lets you connect the audio output of your laptop or MP3 player to a PA system. The 318 has an 1/8" stereo mini on one side and a mono XLR on the other, so you'll always have the right connections when it's time to give your presentation. You won't have to worry about hum and buzz caused by ground loops and RF interference, either, as the 318 has transformer isolation. You also get a handy volume control and a ground lift for killing the noise you sometimes encounter with consumer devices. Your presentations will ring out with crystal clear sound - making you look like the consummate professional you are!

It works

By Sweetwater Customer on November 4, 2022

I use it for a couple of options. One as intended to connect laptop to mixer. But manly I got it to use as an interface from my little guitar amp to a mixer.

Excellent product!

Ben is the Bomb!!

By Richard Edmondson from Creston, NC on June 30, 2022 Music Background: Drummer for 42 years, Sound tech for 10. Guitar owner.

Works great! Got here in the blink of an eye

Simple, Easy, and Functional

By Sweetwater Customer on September 14, 2020 Music Background: Sound Engineer

Needed to link a church computer output directly to sound system Easy as one, two, three. Perfect impedance match, no loss, and truly plug-and-play.

Switchcraft SOLUTION

By Sweetwater Customer on August 10, 2019

I borrowed one of these while at a convention on the east coast recently for a presentation. Very convenient, very reliable and controls are solid. Worth every penny and ensures a flawless performance when utilized as it was designed for.

Sweetwater delivered solid on this order and we'll be back for more.

Did exactly what it's supposed to - dead silent too!

By Keith from Texas, USA on February 16, 2019

I've had an old Behritone C50a ("horrotone" clone) wired haphazardly in mono - well, wired how I read on the 'net how to do it, but it's always been plagued with a tiny bit of hum. This little box completely isolated the stereo phones out (an unused extra on the interface now that I have a hp amp from Sweetwater) so I can listen to my mix in mono on a single driver and hear only the mix.

Perfect for Denon 6000MK2 Xtra mp3 input

By ED KINNEY from jacksonville, FL on December 6, 2018

I ran out of inputs Denon 6000MK2 so I used mic 2 for an mp3. Thanks Justin for the tip:-)

saving money

By Larry Vick from Austin TX on February 27, 2018 Music Background: Live Music and Church

I was so glad I found this, I looked at a lot of very expensive options to connect my MacBook to the PA and this works perfectly. I couldn't be happier. Shaka is awesome

Awesome gear

By Andy from J. on April 30, 2017 Music Background: Small church tech. dir.

This little DI solved three problems with one solution. We had ground hum from our laptop audio. We needed to take the stereo two channel feed from the laptop down to one channel. And the sound quality coming from the laptop could use a little improvement.

This solved all three and sounds great. Great solid construction, compact size, made in Chicago, love that. What more could you want?

This was an awesome find. As soon as we install it the noise problem cleared up.
Thanks Guys

Great For Practice

By Chris Lynch from Gastonia, N.C. on February 10, 2016

I use the Switchcraft for choir practice. I plug my iphone in and we are ready to go. Very easy to use and I love the volume control.

Great, purpose specific box

By Sweetwater Customer on December 11, 2015

Needed a solid 1/8" D.I. for others to use in a plug & play system that would give some volume control, but not access to the actual audio system. This works great. Quiet, clean, and the low profile volume pot protects itself from damage.

NOTEBook/MP3

By Michael Jelineo from Vancouver, WA on July 7, 2014 Music Background: Hobbyist Live Sound Engineer

Amazing Product wish I would of know about this thing when I was bringing my karaoke setup out to the Fair Grounds. Had to use there DI Box which was unbalanced output. If you want a Direct Box Specfically for your MP3 player or Laptop this is it. Highly Recommend this product as well.

Get It You Need it Especally w Bose ToneMatch

By Victor Tarassov from Princeton NJ on April 25, 2014 Music Background: Pro Musician

This really bring the Bose Tone Match to just amazing with backing tracks, mp3 etc files in stereo running out from source but if you're plugging into the Bose system you lose one channel of the signal. The Switchcraft 318 some how dose magic and makes the mono sound great. I use the Switchcraft 318 1/8 to XLR Mini SumBox from iPhone out running One Track (for backing tracks, percussion, and sounds) from Switchcraft XLR to Blose L1 Tone Match (Stereo to Mono) signal sounding very nice. Can't live with out it. It's my secret weapon to make the system sound even better. Thanks Mark Magdich x1265 and UPS for getting this to me. Can't wait to use it this weekend.

Super!

By Pam Green from Florida, USA on March 25, 2014 Music Background: Recording Engineer, Pro Musician, Guitar Teacher

It does exactly what it is supposed to do. I bought it to connect ipod, ipad & android phone to play music through our P.A. system. Works like a charm.

Great product for the price

By Horco from Southern NM on October 23, 2013 Music Background: Live sound and Pro Sports Announcer

I needed an adaptor that would go from a timing system with a digital horn to my mixing board. The timer internal volume was maxed out and not capable of readjustment without sending back into the factory. This AudioStix helped reduce the volume input without redlining the sound system.

Awesome product

By Rusty Johnson from United States on March 19, 2013 Music Background: Live Sound and P.A. Announcer

If you need an 1/8" input to XLR adapter this is what you want. This is pocket-sized and perfect. I use it with my music player for live sporting events to tie-in to the PA. The volume control on the unit makes it perfect for this application. It also ships with an 1/8" stereo cable. Great product, highly recommend.

Removed annoying noise

By Sweetwater Customer on March 1, 2024 Music Background: Sound human, production person & drummer dude.

At a church, someone took TRS 1/8th to TRS 1/8th thru the wall on a 25' run from projector to console. Obviously had buzz buzz. This removed annoying buzz buzz and high pitched ring.

Good Stuff

By Sweetwater Customer on February 22, 2022 Music Background: 45 year pro

Even though I've been doing this for 45 years I'm taking the time to get input from my rep Bob. He always introduces product ideas I hadn't considered. This does what it's supposed to very well and it helps keep your signal clean which is very important to me. It appears solid.

Switchcraft 318 Mini AudioStix 1-channel Passive Laptop Direct Box

By Terry Miller from Florida on April 23, 2021 Music Background: 57yrs pro

I don't know what else it's supposed to do, but for controlling the overall volume for our backing tracks it works great....highly recomended !!

An Excellent Solution!

By Dean K. Wilson from Erie, Pennsylvania on March 18, 2020

I needed to connect the output of a laptop computer to the input of a wireless microphone transmitter in order to stream audio into a classroom sound system during a PowerPoint presentation that had lots of video and audio clips. This simple device provided an excellent, even elegant, solution.

The only downside is that the volume control is a bit difficult to operate. It is almost flush with the case of the unit. There is not much surface for one to grip.

Solved my sound issue

By Joe Swafford from Greenville, SC on October 8, 2019 Music Background: Bass Guitar player

Thanks to Nick Magnani for suggesting the Switchcraft 318 Audiostix. I had a terrible noise issue, called Nick and he suggested this product, then talked me through its setup and use. I would give it a 5 rating, but the volume control knob is to small. Other than that it is prefect.
Again, thanks Nick!

Could save YOUR iPhone!

By Ronald from Atlanta on November 11, 2017 Music Background: Guitar player and vocalist and sound technician

Have larger DI boxes in my toolkit, but didn’t have anything handy when I plugged my 6S into a mixer with the phantom power on. Instant death! Nick Schenkel suggested this compact little sucker and I love it. Excellent build quality and volume pot to boot.

Essential item for your audio kit

By Rand from Nevada on December 9, 2016

Works great at a good price. Small size takes up less space. Construction feels solid. Nice summing stereo to mono to only take up one input on sound board.

Switchcraft 318 Mini Stix

By Horco from Las Cruces, NM on April 22, 2015 Music Background: Sports Announcer, DJ. Music Director

This is a handy piece of equipment for connecting small audio devices several different ways. The ways in which I use it are rather simple. I connect my computer to a mixer and I get absolutely no noise through the line. Another way I use it is by connecting my phone music player to a powered speaker for small outdoor get togethers. The volume knob is ideal in this situation because then you do not have to worry about having to hear the beep from your phone every time you adjust or have to go to the speaker to adjust the volume. And it comes with a 1/8" cord to connect to you phone or computer. It is so small it fits in your pocket and I have used it many times and own two of them. Highly recommend it for your tool box.

Just What the Doctor Ordered

By steve b from groton, MA on February 12, 2015 Music Background: Musician

This well made compact little device is perfect for what I needed.
I wanted a simple interface device for playing virtual keyboards through my laptop with a midi keyboard.
Simple and effective with no noise or hum and I can crank it through a PA or guitar amp with no issues, and you can't beat the price!

Versatile Unit

By Mark Swantkowski from Kingston, PA on June 1, 2014 Music Background: Pianist / Sound Man

If you are running a House of Worship sound system, you want one of these... Forget running long unbalanced lines to the 'aux in' of your mixer... Just run a 50 ft. balanced XLR cable out onto the alter / staging area, and terminate it with one of these... You don't know what people will bring in as an audio source, but the #318 will cover it all... So, now you have a clean source with no high frequency roll-off, no hum or signal loss... And no worries... (m.)

Useful for those with limited Channels

By Kevin Varghese from Opa-Locka, FL on December 18, 2023 Music Background: Audio Engineer

I love the product. Converts a stereo signal into MONO. It is convenient and Extremely Portable.

Switchcraft 318 mini audiostix

We use the Switchcraft 318 Mini AudioStix 1-channel Passive Laptop Direct Box for our movie Night with the

Switchcraft 318

By Sweetwater Customer on September 5, 2016

Switchcraft 318 did exactly what I needed to connect with a BOSE sound system.

Switchraft works great!

By Dan from Buffalo on December 31, 2015 Music Background: Keyboards for 40 years

I like this little unit because it makes it easy to get songs off my ipod into my mixer without loosing too much of the sound. I notice some distortion occasionally, but overall it is a nice little piece of equipment that makes learning new tunes a lot easir.

Great little unit!

By Mr. Saxophone from New Mexico from New Mexico on March 18, 2015 Music Background: Semi-pro musician and music teacher

This connector does exactly what is supposed to do and is very clean sounding. It works with audio interfaces from computers, as well as the 1/8" headphone jack, changes stereo keyboards to mono, and also sends a stereo signal mono to a powered speaker. A very useful direct box style unit!

Switchcraft 318 Mini Audio Stix

By EFEX ED from Seattle, WA USA on May 23, 2014 Music Background: Factory Authorized Audio Tech and Pro Musician

The Switchcraft Mini Audio Stix works well with any MP3 device using a 1/8" stereo jack.. The built in volume control allows for simple adjustment of the sound source and the Lo Z out is fully compatible with most in house sound systems and all portable PA's. The ground lift is a must to enable control of ground loops and noise. A very convenient package indeed !!

Great Compact solution!

By John W. from United States on April 21, 2014 Music Background: Musician / Engineer / Experimententalist

Does what it says and does it well. I'm using it to run a stereo line through an effects box designed for vocals. The built in summing / transformer isolation keeps the signal very clean. This is also a good choice to use in place of a Y cable when you need to sum a stereo source down to mono.

Only thing stopping me from rating this 5 is the 3.5mm holds the plug a little too loosely for my preference.

1 Flaw......

By Jeff from Rochester on June 21, 2017 Music Background: Professional Trumpet Performances & singing

This device works fine but the volume button is very short and slick and difficult to adjust if you run your own sound on the stage. No grooves on it at all to allow you to turn it easily.

works great for what I Need it for .
