Record to your mobile device with the 36" Sescom Stereo RCA to 3.5mm TRRS Plug Line to Mic Level Summing Cable for Mobile Devices which is compatible with audio/video recording apps that accept audio input via the headphone jack. This cable enables you to take a live feed from a mixing board or any other RCA-equipped line-level source and record it directly to your smartphone or tablet via the 3.5mm headphone jack.

Since typical smartphone microphone inputs only accept mono signals, this cable takes a stereo signal, blends the left and right channels together, and gives you a stereo-to-mono mix that plays back in both the left and right sides of your headphones. To prevent distortion, a built-in attenuation pad reduces the signal strength to mic level, and for protection, an electrolytic capacitor prevents DC power from reaching your device.

Related Questions and Answers

Q: 1. Is there the same type cable as this but longer than 9"? I need it for a GH5 on a gimbal.

A: I would say 12 to 14 inches.

Q: 2. Will this work to connect the stereo line out from an amp to a single channel 3.5 mm input of a subwoofer? (A simple y-splitter cable makes the amp sound horrible.)

A: No. This Sescom cable is a line-to-mic attenuating cable intended for connecting line level signals to the mic input on a mobile device like smartphone or tablet. The 3.5mm end is TRRS, not TRS. You can use a Y-cable such as the Hosa Technology REAN 3.5mm TRS to Dual RCA Pro Stereo Breakout Cable (B&H # HOYCRTRSRCA6) to connect the output of an amp to a subwoofer.

Q: 3. Is there noise/interference with two sources connected?

A: The Sescom A/B switch is passive and does not use any batteries or power to function. There should not be any noise or interference when two sources are connected.

Q: 4. It seem obvious give TRS and 2xRCA plugs, but I would like to confirm that is two channel (stereo) out to the camera?

A: The Sescom SES-43DB-MZ2P Attenuating Line to Mic Level Cable is used to send line level audio from RCA left and right outputs to a camera's 3.5mm TRS microphone input. The cable has a built-in attenuator to pad the signal by 43 dB which will prevent any clipping or distortion.

Q: 5. what cables do i need connect to pc's?

A: Each device requires one 3.5 mm male to 3.5 mm male stereo audio cable. Be sure the one connecting to the computer is long enough to reach from the sound card headphone jack to the location of the switch.

Q: 6. it says 36ft in length but I received a 3ft cable when i purchased this. Do they really come in 36ft length?

A: The length of this Sescom cable is listed as 36 inches, which is 3 feet. The information for the cable length is clearly stated in the product title, description, and specs. Sescom also offers the same cable in 12" and 18" length, but 36" is the longest length available. If you need a long cable, the best option would be to use female RCA adapters such as the Pearstone RCA to RCA Female Coupler - Pair (B&H # PEPARFRF) which will allow you to attach another dual RCA cable in the length you choose. We do offer long RCA to RCA cables such as the Kopul 2 RCA Male to 2 RCA Male Stereo Audio Cable - 30 ft (B&H # KOSRC4030) or 50 ft (B&H # KOSRC4050). When used together with the adapters and a longer extension cable, the Sescom cable will still provide line to mic level summing for a mobile device.

Q: 7. Can I use 3.5mm male mono connections? Reason is I am connecting two radios and the output speakers are mono

A: Yes this will work fine for that purpose.

Q: 8. Is the (RCA) monitor out a passthrough from the RCA inputs?

A: Yes, the Sescom SES-ON-THE-LEVEL's monitor output is a direct passthrough from its inputs.

Q: 9. I want to capture the sound on a phone, the audio signal is coming from an HDMI source going through an HDMI audio extractor, will this cable do the correct job of mixing left and right channels?

A: The Sescom Stereo RCA to 3.5mm TRRS Plug Line to Mic Level Summing Cable will take the stereo output signal and combine the left and right channels to mono so the audio on both channels will be exactly the same.

Q: 10. Will this perfectly work sending an audio feed from my Zoom U-24 Audio Interface into an android smartphone, iphone/ipad?

A: Yes, that cable should be compatible for that application, provided the Zoom product has 1/4 jacks.
