Master Volume Knob
These checkboxes determine which analog output pair(s) will be affected by the Master Volume knob (8) 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 2626 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.
▶ 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 a an external mixer).
TIP: If you control your monitoring levels externally (i.e, through a mixing board or by
using your speaker’s own level control) then the Master Volume knob on ProFire 2626
can be used as an aux send knob:
Connect ProFire 2626’s analog outputs 3/4, 5/6 and 7/8 to your external effects
processors’ inputs. Configure your audio software so that audio signals that are to be
processed by the external gear are routed to these outputs.
Using the ProFire 2626 Control Panel, assign the Master Volume knob to control analog
outputs 3/4, 5/6 and 7/8.
The Master Volume knob on ProFire 2626 can now be used as a dedicated aux send
knob for external effects processing.
Lastly, connect the outputs of your external effects processors to the analog inputs on
ProFire 2626. You can now monitor the incoming signals through the DSP mixer, and/or
route them to your audio application for recording.
TIP: To control the level of the main monitor mix without affecting the level at the
headphone outputs, assign the Master Volume to either analog outputs 5/6 or 7/8 and
use those outputs for your main monitors.
This will allow you to route independent cue mixes to headphone output 1 (which always
plays audio routed to analog outputs 1/2) and headphone output 2 (which always plays
audio routed to analog outputs 3/4) while still using the Master Volume knob to set
levels for your studio monitors. This prevents the Master Volume Knob from influencing
the levels of headphone outputs 1 and 2 and effectively provides front panel volume
control of three discrete stereo outputs. See the section entitled “Example Scenario #1:
Recording a Duo” to learn more about creating cue mixes.
