Turn your Zoom H2 digital recorder into an audio USB interface 

For Windows 10 there is one extra thing you need to do otherwise the H2 will appear as a device in settings but won't transfer any audio. In the AUDIO i/F menu, before using CONNECT, you need to go into FREQUENCY first and check it is set to 48kHz not 44.1 kHz. If you are using your H2 into a DAW like Cakewalk you may have to set it up as the selected input device (instead of your normal interface) and set the driver mode to WASAPI SHARED if it is previously set to ASIO. It will then appear in your inputs selection just like an interface and you can select Left Right or Stereo to go to your recorded track

Thank you for the tip. I record via an Analogue mixer into a Zoom H2n but I use the left and right Phono outputs from the mixer into the zoom rather than the headphone output .The phono output is lower (line level I think) and intended for recording and is less likely to distort the sound with too strong a signal and therefore I do not have to turn the recording level right down ..The head phone output is used to drive headphones which do not have a preamp in them. This does require a left and right phono cable into 3.5 jack plug though. . easily available from Amazon.

Gracias Eric !!

Great, thank you, useful!

Hola Erick, agradecido por tus consejos. Ahora bien, he conectado mi zoom H2 a un celular android por medio de un conector OTG, mi celular lo reconoce como interfase para grabar mis videos Drum Covers, pero el detalle es que se produce una gran latencia. Sé que en una computadora con un programa se puede regular, pero como podria reducir la latencia en mi celular? Muchas gracias!

muchas gracias!. buena información.

is it possible to use the zoom h2 as an external micro for smartphone?

You do require the driver for the H2 first in order to do this, yes?
