DA11 Quickstart Guide

Quickstart Guide- Basic Settings

To familiarize yourself with the operation of the front panel controls of the DA11, it is
advisable to connect the DA11 to AC power before making any other connections, and
try the suggested settings in this guide.

The two switches under the SELECT legend are used to change settings.

- The left switch marked moves the cursor left or right as indicated by the arrows.

- The right switch turns the setting “On” or “Off” each time the switch is clicked down in
the “set” direction.

- Click the

switch down to enter the Setting mode.

- Click the right switch up towards “exit” to exit the Setting mode.

- Setting example- USB input, output “On,” Pin 2 Hot for RCA connection

(change from the factory default setting*).

1) Turn the DA11 power “on” and wait for the two IMAGE LED’s to appear.

2) Enter Setting mode by clicking the

3) The rapidly flashing cursor will appear at the first position on the left (xlr).

4) Click the

switch down twice so the flashing cursor appears above the “usb”

legend.

5) Click the right switch down towards “set” and the cursor will flash rapidly to
indicate the usb input has been selected. The LED above “xlr” will go dark.

6) Click the

switch down five times to position the flashing cursor above the pin

3 legend. The LED above “usb” will stop flashing and stay illuminated.

7) Click the right switch down towards “set” and the cursor will change from flashing
rapidly to flashing slowly to indicate that Pin 3 has been grounded (is “off”).

The display should look like this (were

symbolizes the slowly flashing cursor):

10.) Click the right switch up towards exit to exit the Setting mode. After about ten
seconds, the “LE” symbol will appear in the VOLUME display to indicate the settings
have been stored in memory and the DA11 is in Operating mode.

11.) Please reduce the DA11’s Volume setting to a low value (“00” to “05”), wait for the
“LE” symbol to re-appear before turning the power “Off,” and see the CONNECTIONS
section of the manual.

* The factory default settings are: xlr input, output “on,” invert “off,” pin2 “on,” pin 3 “on,”
& dim “off.” The default setting display looks like this (were

Quickstart Guide- Settings and Operation

The DA11 front panel has three sections: (Diagram 1)

There are two main modes for the DA11- the Operating Mode and the Setting Mode.

- In Operating mode, the front panel displays the status of the

Control™

in the IMAGE section. The VOLUME display indicates the setting of the

>PiC< Playback Image

volume control when the volume is adjusted and for approximately 10 seconds
afterwards. The VOLUME display then reverts to displaying “LE.”

- In Setting mode, status of the settings is displayed along with the position of the cursor
in the IMAGE display section. The position of the cursor is denoted by the flashing LED.
When an active input is selected, the VOLUME display will indicate the sample rate of
the digital audio input. If the input is not “locked” or there is no signal present on the
selected input, the VOLUME display shows the symbol “- -“

- Approximately 10 seconds after exiting Setting mode, the VOLUME display reverts to
“LE” to indicate that the settings have been stored in non-volatile memory. This means
the DA11 will retain the settings even if the power is turned “off.” Any time the VOLUME
display reverts to the “LE” symbol, the settings are stored, including after any volume
adjustment from the front panel or remote.

Diagram 1, Section 1- Setting Controls

The two toggle switches on the left side of the front panel under the SELECT legend
control the Setting mode of the DA11.

The first switch labeled with the

- Clicking the switch down while in the operating mode causes the DA11 to enter Setting
mode. A flashing cursor and the indicators for settings that are “on” will appear in the
IMAGE display window

- While in Setting mode, clicking the switch down moves the cursor one position to the
right and clicking the switch up moves the cursor one step to the left.

- The position of the cursor is retained when exiting Setting mode, so the cursor will
appear at the same position it was in when Setting mode is re-entered (in other words,
clicking “set” will turn the same function on and off). The exception occurs when AC
power is first turned “on;” the cursor will always appear in the left-most position (xlr).

The second switch is labeled “exit” and “set.”

- Clicking the switch down (set) toggles the function On and Off. In the case of selecting
an input, the input at the cursor position is enabled and all other inputs are disabled.

- Clicking the switch up (exit) immediately exits the Setting mode.

- After exiting the Setting mode, clicking the switch in either direction has no effect.

symbols has two functions:

DA11 Quickstart Guide

When in the Setting mode, the LED’s above each label indicate the status of each
setting. The cursor position affects the way an LED indicates the status.

- At the cursor position, a rapidly blinking LED indicates “on” and slowly blinking cursor
indicates “off.”

- At all other positions, a steadily illuminated LED indicates “on,” and an LED that is not
illuminated indicates “off.”

Please note that in the following Setting mode function descriptions, the distinction
between whether the LED is at the cursor position or not may be omitted for clarity

.

Diagram 1, Section 2- Setting Mode Display (only in Setting mode)

- Input selection. This consists of the xlr, opt (optical), usb, and rca labels and the
LED’s above them. Only one input can be selected at any time.

- If the cursor is positioned at the selected input, the LED flashes rapidly.

- If the cursor is positioned at an input that is not selected, the cursor LED flashes slowly.

- When an input is selected, and the cursor is at a different position, the LED for the
selected input is constantly illuminated. If the cursor is positioned at a different input,
clicking the “Set” switch will enable the input at the cursor position and disable the
previously selected input.

- Once an input is selected and the cursor is still at that input position, subsequent “set”
clicks toggle the input on and off.
!!! Please Note: there are settings in the computer that affect the operation of the USB
input. Please see the “USB INPUT” section of the manual for details.

- Output muting. The main (XLR) outputs of the DA11 can be muted while the
headphone output remains active.

- If the output setting is “on” as indicated by the LED, the outputs are “on.”

- If the output setting is “Off,” the main outputs are muted.
This function operates differently than the Mute function controlled by the optional
infrared remote. Like other functions in the Setting mode, if the cursor is positioned at
the output LED, it will flash rapidly to indicate that the function is “On.” Clicking the set
switch once will mute the outputs and this will be indicated by a slowly flashing LED.
When the cursor is at another position, the LED is “off” (not illuminated) when the
outputs are “off” (muted).

- Please use caution when turning the outputs “on;” it is a good idea to set the

volume to a low setting prior to turning the outputs “on.”

- Polarity Invert. This function changes the audio signal polarity of both the main
outputs and the headphone output. The invert function is operational for all main output
configurations- balanced or unbalanced.

- If the invert function is “on” as indicated by the LED, the polarity is inverted in the
output audio for Pin 2 “+” operation and headphones.

- If the invert function is “off” as indicated by the LED, the polarity is not inverted in the
output audio for Pin 2 “+” operation and headphones.

- The sense of the function is reversed for Pin 3 “+” operation. For example, if the invert
function is “On,” the output audio signal is not inverted for Pin 3 “+” operation.
