Headphone / Line Mixer
All of the sources selected for the output jacks of the TubeFire 8™ are mixed together to provide a signal for
the Headphone/Line Mixer Output. Use the Output Source switches to select which channels are from the mic
preamps and which channels are from the computer in the headphone output mix.
You can use this function to check the operation of the input channels as well as for multi-tracking punch-ins.
NOTE: Signals sourced directly from the TubeFire 8™ preamps have zero latency whereas signals from the
computer may have a finite amount of latency depending on the computer and software set-up.
Mix Level Control
The Mix Level control adjusts the output level present at the headphone jack. This control mutes the output
when centered at 12 o’clock. Choose a stereo mix by turning clockwise or a mono mix by turning counter-
clockwise.
The stereo mix has odd numbered channels in the left channel and even numbered channels in the
right.
You can use the headphone output as a stereo line output as well as for driving headphones.
Power Switch
This switch controls and indicates that the unit is powered up and operational. When dimly lit, it indicates a
low power source or an internal problem.
