Input Gain Section
Each of the SpeedIO’s input channels has its own independent GAIN controls and level monitoring LEDs.
Both of the audio inputs allow either 1/4” jack plugs or XLR type connectors to be plugged in and the input
sensitivity of the high quality pre-amplifiers can be adjusted to accommodate different signal levels.
Adjusting the Input Gain
With a microphone plugged into a channel, turn the appropriate GAIN knob until the GREEN LED above
the GAIN knob is fully lit when speaking or singing into the Microphone and the RED LED occasionally
flashes.
This will set the gain of the preamplifier to the correct level for the Microphone such that it will not distort
or be too quiet when recording. If the signal level is found to be very low, pressing the appropriate GAIN
BOOST switch (see page 8) will increase the signal level by 20dB.
Check that the Audio level that is being sent from the SpeedIO to the recording software is not too low or
too high. To do this, look at the input meters within the recording software.
LINE OUT LEVEL Control
This control adjusts the level of Audio signal being passed from the SpeedIO to the audio output jacks.
