ProFire 610
Mixers Active at Sample Rates Above 96 kHz
When operating at sampling rates of 176 4 or 192 kHz, ProFire 610 can use two of its available Monitor
Mixers These two drop-down menus allow you to select which two mixers will remain active at sampling rates
above 96 kHz For example, if you would like to use the “Analog Out 1/2” and “S/PDIF Out L/R” Monitor
Mixer tabs, select them from the “Mixer 1” and “Mixer 2” drop-down menus
Note that when operating at sampling rates of 176 4 or 192 kHz, signals can still be sent to outputs that
are not selected in these drop-down menus However, these outputs will not feature any monitor mixing
capabilities (i e , the outputs of your audio software will be routed directly to the output and you will not be
able to modify your signals before they reach the physical output ports)
Master Volume Knob
These checkboxes determine which analog output pair(s) will be affected by the Master Volume knob
6
on the front panel of the interface: If a box is checked, the volume level of its corresponding outputs will be
controlled by the Master Volume knob; if a box is left unchecked, the outputs will play at full volume regardless
of the position of the Master Volume knob
This feature gives ProFire 610 a great deal of flexibility in how it can be used For example, in multi-channel
“surround” mixing scenarios, you can use the Master Volume knob to simultaneously set the level of all
speakers by checking the outputs that are connected to your speakers On the other hand, if you are mixing
in stereo using outboard equipment (i e , compressors, reverb modules, etc ), you can use the Master Volume
knob to set the output level of the “main” outputs (connected to your speakers) while allowing the additional
outputs (that are connected to your external equipment) to remain unaffected This will let you use the Master
Volume knob to set the loudness level of your speakers without affecting your external gear
Note that the Master Volume Knob settings remain active even if the interface is used in Standalone Mode
For example, if the Master Volume knob is assigned to control analog outputs 1-2 in hosted mode, the
Master Volume knob will continue to control the levels of analog outputs 1-2 when ProFire 610 is used as a
standalone device
!
WARNING
: Unchecking one of the Master Volume Knob boxes allows its corresponding
outputs to play at full volume (i.e., without any attenuation). This may result in very loud signals
being sent to your speakers, headphone amplifiers, or other equipment. Be mindful of your
outgoing levels anytime you uncheck one of these boxes to avoid potentially damaging your
equipment (or hearing). If you wish to leave these boxes unchecked in order to allow full,
unattenuated signals to play through the interface, it is strongly recommended that you have an
external provision for controlling your levels (such as an external mixer).
