position. Please note that the perceived effects of these adjustments are very program
dependent, and may result in a change in acoustic level. One extreme example is mono program
material- adjusting the >PiC<™ controls to the same setting on both channels will not change the
apparent location of the sound in the stereo sound field.
>PiC<™ is comprised of the LED display in the center of the front panel below the “IMAGE” and
numerical legends, and the two switches labeled “wide-narrow” and “narrow-wide.” The function
can be controlled by the two switches or from an optional infrared remote (please see the
OPTIONAL INFRARED REMOTE section for details).
Adjustment of the >PiC<™ is indicated by the position of the illuminated LED’s. Moving the
settings in the “wide” direction (“+” numbers) increases the apparent width of the stereo sound
field. Moving the settings in the “narrow” direction (“-" numbers) decreases the apparent width
making it closer to “mono.” Similar to the VOLUME up/down control, single clicks move the width
setting one step and holding the switch moves the setting until it reaches the end of the
adjustment range.
When the “Mute” function is enabled by an optional infrared remote, the LED’s that normally
indicate the setting of the >PiC<™ turn “off” to indicate that all audio outputs are muted.
In other words, when Mute is enabled, the entire IMAGE window is dark in Operating mode.
Volume Control-
A digitally controlled analog volume circuit is used to control the volume of the XLR and
Headphone outputs. The advantages of this approach are:
- Extremely consistent sound quality regardless of volume; much better than a traditional
potentiometer “knob” type of control.
- Excellent matching between channels at every volume setting for consistent stereo balance.
- Ease of reset-ability for listening or critical monitoring at a consistent level
The volume control consists of the numerical display under the VOLUME legend, and the
up/down switch just to the right of the display. The volume can be controlled in one dB steps from
full volume (56) to the lowest volume (01), When the display indicates “00,” the signal is muted.
Holding the up/down switch in either position will cause the Volume setting to change
continuously until the switch is released or the setting reaches the end of the range.
The up/down switch is always active in both Operating and Setting modes once the DA11 has
finished the power-on initialization. Likewise, the volume setting will also change in Setting mode
when the DA11 accepts a remote volume command (the Safe Mode setting affects remote
Volume commands; please see the OPTIONAL INFRARED REMOTE section of the manual).
The display reverts to “LE” approximately ten seconds after the last Volume control input (front
panel up/down switch or infrared remote). This indicates that the settings have been stored in
non-volatile memory. It also indicates that commands other than “mute” will not be accepted from
the infrared remote if SAFE MODE is enabled (please see the OPTIONAL INFRARED REMOTE
section for details). Any time the volume is adjusted, the display will change from “LE” back to the
numerical volume setting (in Operating mode).
Determining the Correct DA11 Volume Setting for Your System-
Please be certain to configure the outputs of the DA11 for the proper balanced or unbalanced
setting to match the wiring and inputs of your system. See the section titled CONFIGURING THE
XLR OUTPUTS for details.
There are two ways the DA11 can be used to listen to digital audio sources through speakers:
1.) Connect the main output of the DA11 to the input of a receiver or preamp, set the DA11 to a
“fixed” level, and adjust the speaker volume using the volume control of the receiver or preamp.
