This is because Zoom does not support multi-channel ASIO driver types.īy default, Zoom will sum these inputs to mono. You can choose which two inputs you wish to use, but first you need to follow the steps in this article. Zoom will only be able to receive audio from two inputs of your audio interface. To confirm the quality of your incoming audio signal, you can create a test recording and listen back. If you are using a condenser microphone (for example the CM25), please ensure 48V phantom power is enabled on the front panel of your interface. This indicates an audio signal is being received by Zoom. You will be able to see a visual indication on the 'Input Level' meter. Speak into the microphone connected to the audio interface. Set the Microphone (Input) and Speaker (Output) to the audio interface you would like to use.ģ. To set your Focusrite interface as the audio device in Zoom, please ensure your interface is connected and powered, and open up Zoom.Ģ. Setting the audio interface as the audio device Requirements: We recommend creating a Zoom account and downloading/installing the Zoom Client for Meetings desktop application from the Zoom website here, as the web client has limited features. Please see the following article if you are on a Mac computer: How to set up your Focusrite audio interface with Zoom on a Mac This article will explain how to set your Focusrite audio interface Zoom's audio device which will allow you to get audio from your microphone/instrument and computer audio into your calls. I tried to graph my results, but I'm absolutely hopeless with Excel graphsįinally, I guess the measurements are limited by my source, however the intention here was to demonstrate a trend. I also notice that when the input level controls are around the 11 o'clock position, setting the levels is quite difficult, as they jump about with the slightest touch of the controls.Ī quick comparison with Arta shows the THD measurements agree with RMAA. zip version of the Excel spreadsheet, which I have tried to reproduce below (without too much success!).īasically, for THD measurements, it looks as though 775mV is optimal, and for SNR measurements, 2.8V is optimal - any higher and it becomes difficult to adjust the input levels. Source was an Ebay DAC kit (LJM AK4396) via my isolation test box (gain of x2) These measurements were taken with RMAA, levels were set to -1dB, sample rate was 96kHz (even though mine supports 192kHz, I find that noise and THD seem optimal at 96kHz). I did a spreadsheet with input voltages spanning 400mV to 2.8V RMS, verified with a 'scope. Distortion and S/N measurements at various levelsįurther back in this thread (I don't recall which post) it was mentioned that the measurement values with the Focusrite vary according to input voltage.
