Testing

Have another person speak into each microphone at normal to loud levels. Watch the
corresponding Input Level LED on the front panel of the DMX8 USB Mixer. As each
microphone is tested the LED should flash green. It is acceptable for the LED to flash red
occasionally with loud speech. If the microphones are placed close together the voice test
should be accompanied by a “scratch” test. Before speaking, lightly scratch each
microphone and observe which LED on the front panel lights. This ensures the correct
microphone is being tested. If devices other than microphones are connected to the inputs
of the DMX8 USB Mixer, perform a similar test on these devices.

After the drivers and the DMX8 Configuration are installed use the configuration program
to adjust the recording and monitoring levels. See the Configuring the DMX8 USB Mixer
section later in this guide.
