But MixerFace is also a versatile mixer. It has an Auxiliary stereo input that can be mixed in right on the top panel. So if you want to add a drum machine or another mixer, it’s there. MixerFace also has Balanced outputs, an Unbalanced stereo line output and a loud Headphone output. The top panel gives you easy access to all of the adjustments, using familiar analog pots. No searching through menu pages to find the right adjustment — quick and easy controls are always at your fingertips.

A: Yes. You can use any power bank with USB output — size is not important as long as it’s above, 5000 mAh. Most power banks are above 10,000 these days.
5) Q: My MixerFace isn’t charging! OR My MixerFace is not recognized by my USB device!
A: Check that you are connecting MixerFace via the correct USB port. There are two USB ports on MixerFace. One for charging (lightning bolt symbol) and one for USB audio connection (the USB symbol).
6) Q: Can you record to a USB device and the built-in SD card recorder in the R4R model?
A: Yes. MixerFace R4R offers the ability to record to both places at once for safety and redundancy.

A: Recordings made to the SD card recorder are fixed at 24bit/48kHz. Recorder produces Stereo WAV Files.

10) Q: Does MixerFace have an app?
A: MixerFace doesn’t need an app. It’s simple to use and can be operated entirely from its front panel. Use it with any app you want.
Examples of 3-rd party recording apps include: Audio Evolution (iOS/Android), Auria Pro (iOS), Garageband (iOS), Field Recorder (Android) and Twisted Wave (iOS).
11) Q: Will MixerFace work with Android device?
A: Most Android devices 3 years old or newer should work fine. The phone must support USB audio (not just charging). USB C ports usually mean that the phone is newer. We recommend flagship phone models that support external USB audio devices. The following site has a good list of phones known to support USB audio devices:
http://www.extreamsd.com/index.php/technology/usb-audio-driver (scroll down to “Supported Android devices”)
12) Q: Does MixerFace take power from the connected Android phone?
A: MixerFace (R4, R4R, R4B) has a built-in battery, so it draws zero power from the phone. MixerFace R4S uses wall power from a standard 5V USB adapter. It also doesn’t draw any power from the phone.
13) Q: May I leave MixerFace permanently plugged in to the charger?
A: Yes. MixerFace can be permanently plugged in to a USB charger, or a computer’s USB port. MixerFace will top off the internal battery every once in a while, but otherwise will consume very little power when turned OFF.
14) Q: With Windows 7 and 10, Playback works recording doesn’t work. OR: My app does not work with MixerFace.
A: Recording and Playback sample rates must match. Open Windows Sound Control Panel. In the Advanced settings, set format to 24-bit with your desired sample rate for playback settings and select identical values for recording settings.
15) Q: To hear myself clearly on playback I have to turn the monitor all the way to the max.
A: See the knob labelled CH <-> USB in the middle of the channel strip. Turn that knob counter-clockwise to get more microphone in the headphones. That is the “blend” control knob and it lets you adjust the mix between your voice and the sound coming from the computer. If you turn it CCW you will hear more of the mic signal in the headphones. If you turn it CW you will hear more USB return signal. Return signal is useful when you are narrating over a music bed, listening to a producer cue on a remote broadcast, etc. Also, turn the blend knob to the USB side when you want to hear playback of something you just recorded.
