C. OPERATING MODE
When AC power is first turned “on,” the DA11 initializes for a few seconds. Once the indicator
LED’s appears in the IMAGE display, the unit has entered Operating mode. All of the settings
(including the Volume setting) are restored to the state they were in the last time the “LE” symbol
appeared before the power was tu
rned “off.” Turning the power “off” before the LE reappears will
result in the last setting changes
not
being stored in memory.
>PiC
< Playback Image Control™
-
This proprietary system controls the apparent “width” of the stereo image, and allows the position
in the stereo sound field of each channel to be controlled individually. Decreasing the width of the
stereo image when listening with headphones or to compensating for asymmetric placement of
speakers in relation to the listening position are examples of when this feature could be used.
Please note that the perceived effects of these adjustments are very program dependent, and
may result in a change in acoustic volume 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 (+2, +1, 0, etc.)
, and the two switches labeled “wide-narrow” and “narrow-
wide.” The
>PiC
<™
function can be controlled by these two switches or from an infrared remote
(please see the OPTIONAL INFRARED REMOTE section for details).
Adjustment of the
>PiC
<™
i
s indicated by the position of the illuminated LED’s. Moving the
setting
s 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).
