Operation
Operation
Duet’s settings may be easily changed using either its top panel encoder or the variety of
software control panels described on page 10. Though several options are possible, you
can choose the hardware and software controls that best suit your individual needs. For
example, Logic Pro users may choose to adjust levels with Duet’s top panel encoder and
change static settings (such as input selection or phase) from the Apogee Control Panel
found in Logic Pro 8. For convenience, many settings may be controlled from multiple
control panels. The chart on page 9 indicates the settings and functions that may be
changed from each control panel.
Duet Top Panel Encoder
Duet’s top panel encoder provides simple and immediate control of input and output level
settings.
Output level
To change Duet’s output level (i.e the listening level of headphone and connected
speakers), press and release the encoder repeatedly until the OUT LED lights.
Now, turn the encoder to the desired listening level. The hardware encoder
operates in parallel with any software level controls.
Input level
To change Duet’s input level (i.e the recording level of mics and instruments),
press and release the encoder repeatedly until the IN-1 or IN-2 LED lights.
Now, turn the encoder until the desired recording level is obtained
(as seen in your recording software).
Mute outputs
To mute the line and headphone outputs simultaneously, press and hold down
the encoder until the OUT LED blinks; press and hold again to unmute outputs.
MIDI controller
The encoder can also send MIDI Controller and Song Position data to software
applications. Please see pages 16-17 for details.
