Product Details

Parts Express 3.5mm Slim-Plug Stereo Male to 1/4" Mono Male Adapter Cable 6 ft.

With audio electronics getting smaller all the time, the 3.5 mm stereo cable is becoming a much more common way to connect audio sources such as computers, cell phones, and MP3 players to amplified speakers, home stereo equipment, or portable DJ systems. Of course, a stereo 3.5 mm output can be tough to connect to a professional mixing board or professional powered speakers can be tough. Everyone in the business, at one time, has had to deal with a noise-inducing mess of Y-cables and plug adapters to connect an MP3 player to the house sound system. No longer! This cable makes it a simple, one-piece affair.

The slim plug 3.5 mm connector on this cable fits more than just the visual aesthetic of today's electronics. The 6.5 mm diameter plug with integrated strain relief works with many protective cases that you'd have to remove for use with a traditionally-sized plug, easing frustration and saving wear and tear. Designed with 100% shield, this cable resists external interference and noise that kill your musical experience.

Parts Express 3.5mm Slim-Plug Stereo Male to 1/4" Mono Male Adapter Cable 6 ft.
Parts Express 3.5mm Slim-Plug Stereo Male to 1/4" Mono Male Adapter Cable 6 ft. is rated 5.0 out of 5 by 4.
Rated 5 out of 5 by from Why didn't I think of thisAs a gigging musician I generally use my iTunes folder for music while on a break. I'm tired of trying to find stereo to mono adapter jacks that either don't make a secure contact or get lost in the bottom of the gig bag. This cable is perfect. The 3.5mm jack is small enough to clear the protective case on both my iPads and plugs right in to any channel on my amp. I bought 12 just to have everywhere I could possibly need them.

Parts Express 3.5mm Slim-Plug Stereo Male to 1/4" Mono Male Adapter Cable 6 ft.

Does this cable actually combine the L and R stereo into a single mono channel, or does the mono just connect the L -OR- R channel and leave the other one disconnected/unused?

Asked by: Brock Samson
This does not combine both, it uses one or the other and leaves the other disconnected.

do you have any cables that are 3.5 male to 1/4 male, mono on both ends? I cannot seem to find that common cable anywhere on your site.

Asked by: mjbz
Unfortunately we do not have any that are mono on both ends. A stereo will work in place of a mono, so this cable will work for your application.

Do you have any that are shorter, 2-3 ft?

Asked by: Brian Loftus
At this time we are only carrying the one size of 6 feet.

Those selling $100+ DI's say never sum your stereo signal to mono with a simple cable or parallel DI jack for risk of damaging your device. Are stereo-to-mono DI's really needed? Or is a cable like this into a basic DI safe enuf? U still get pad/lift/etc

Asked by: PGH1
It depends on the device but ideally you should not connect the left and right channels to each other. If you did this on your stereo you would probably blow your unit. But phones and low power devices are different and some cases will have built-in protection just in case you you do connect the two channels together. Many people have used cables like this for years without any problems but if you turn up the volume and you hear distortion then you should probably switch to a Stereo to mono DI or some other type of mixing device.
