“How can I record to my Nexus 7 with an external microphone?” This question has been posed across the internet as Nexus 7 users search for ways to get high quality audio into their Android tablets. Fortunately, it is possible! There area actually multiple ways. Let’s take a look at the possibilities!
This is a particularly poignant question in light of the fact that the easiest way to get audio from an external microphone into the typical Android device does NOT work with the Nexus 7 tablet. I speak of the TRRS to XLR (or whatever) adapter.
The Nexus 7 tablet’s audio jack is not TRRS. There is no provision in the audio jack hardware for a microphone input signal. According to iFixit, the internal circuitry is not the restraining factor, but the jack itself. It is possible to replace the jack and solder the appropriate cables to the circuit board, but that is beyond the ability and/or will power of most of us. This would obviously void whatever warranty you may have had.
What other input methods do we have for audio on the Nexus 7 tablet? Why don’t we look at the only other port on the device: The charging port. Bringing audio into an Android device through the USB charging port via an OTG (On The Go) cable is a relatively new development. For more on this, check out our article on recording to an Android phone or table from a USB microphone or audio interface.
This means that you can use certain USB microphones or USB audio interfaces (even some mixers) to bring audio from an external microphone into the Nexus 7 tablet via the OTG cable plugged into the charging port.
If you are having trouble with a specific device be sure to try it while using an AC powered USB hub. Your Nexus 7 tablet may be having trouble powering the USB microphone or USB audio interface. If this is the case, the AC powered USB hub should take care of the problem. This is definitely an inexpensive option for getting getting high quality audio into your Nexus 7, but many users may not be happy with the limited functionality of the associated recording app.
I must confess that I have not personally tried this method. When I do try this, I will do a full report here on the AAR blog, but theoretically speaking you could use a JK Audio Bluetooth device to bring audio into your Nexus 7 device via the Bluetooth connection. JK Audio has a range of Bluetooth to XLR converter devices that can be purchased in both Male and Female XLR versions, 3 or 5 pins. For most 3-pin XLR dynamic (no phantom power) microphones, you will want the JK Audio Bluedriver F3 (F = Female , 3 = 3 pins). At $236, this is not an inexpensive option, but it does come with the added flexibility of being wireless. No more dongles or extra converter cables. You are not limited to just microphones either. You can also plug this into the output from a mixer to port the audio directly into your Nexus 7.
DIY Bluetooth (on the cheap)
If you don’t mind a less aesthetic solution, you could probably cobble something like this together on your own using the following:
- Bluetooth Transmitter Adapter – $25
- 3.5mm Female to Female Coupler – $2.49
- 1/8″ Stereo to Female XLR Cable (12″) – $6.64
For $34.13 (view list here) you can have a DIY “Bluedriver” that takes audio from an XLR microphone or mixer and sends it to your Nexus 7 via Bluetooth. It won’t be nearly as aesthetically pleasing, but for a $200 discount, I can live with that.
Despite the lack of the TRRS jack, there are several options to record to your Nexus 7 device with a high quality external microphone or audio source, XLR, USB, or otherwise. I hope this article is a help to you.
