2.2D12 user interface

The LCD [4] acts as a user interface for all menus within the D12. The cursor is controlled via the digital rotary encoder, LEVEL/PUSH MENU [3]. In the main menu the encoder acts as a level control. Pressing or turning the encoder gives access to different menu levels or allows configurations or values to be entered.

Also refer to the D12 Hardware manual, section 3. Controls and indicators.

2.2.1 Conventions for the cursor and menu control

Position cursor

Turning the encoder moves the cursor through the menu. Turning to the right moves the cursor down in the menu tree or to the right. Turning to the left moves the cursor up in the menu tree or to the left. Pushing the encoder activates the Edit-Cursor, except for switching functions (e.g. "on/off"). In these instances pushing the encoder leads directly to a change in value or condition (toggle).

Edit cursor

The current value is displayed beside the cursor and is changed by turning the encoder. Turning to the right increases the value, tuning to the left decreases it. A change is immediately effective, except for the functions "Speaker Selection", "Lock", "Remote", "Device Name" and "Backlight" where a confirmation is required. Exit the edit mode by pushing the encoder and return to the Position-Cursor.

Information cursor

The Information-Cursor indicates fields within the menu tree where the displayed data cannot be changed.

Menu change

An arrow indicates another menu level. Selecting it with the PositionCursor and pushing the encoder enters the corresponding submenu.

Back

Short click: exits the selected menu by moving back one level. Long press (approx 1 sec.): navigates back to the main menu.

Scroll bar

Where a menu tree is longer than can be displayed, a scroll bar is shown on the right hand side of the display for orientation.

Other cursors or signs Highlight

A highlighted field indicates that the data displayed can be changed in edit mode (see also Edit-Cursor above).

Pointer

In the submenus "Lock/Code" and "Device-Name" the field for text input is highlighted and additionally indicated by an arrow.

2.3D12 Boot screen

The boot procedure takes approximately 4 seconds during which the device name, the manufacturer's name (d&b audiotechnik) and the firmware version are displayed.

The transition to the Main screen is carried out automatically.

2.4D12 Main screen

The main screen displays all important settings and status information in one view.

In the first line the device name is displayed. If no device name has been entered, the firmware version is displayed.

D12 Settings menu

From the main screen the "Settings menu" is entered by pressing the encoder for approx. 1 sec. It contains general settings for the device and gives further access to submenus.

In the first line the dbCAN-ID is displayed on the right hand side. A detailed description of the CAN-ID is given in the submenu "Remote" and the Remote section on page 21 in this manual.

Back

Exits the submenu.

Input

Selecting "Input" and pushing the encoder allows the setting of the input type. Turning the encoder one detent to the right and back toggles between analog and digital input.

analog:

The analog input section INPUT A/B and INPUT LINK A/B is active.

digital:

The digital AES/EBU INPUT and LINK is active.

Notes on the digital AES/EBU input Sampling rates:

The input accepts signals with sampling rates of 48 or 96 kHz. The frequency is detected automatically and is displayed as shown opposite.

Signals with other common sampling rates (32/44.1/88.2 kHz) are detected but cannot be used by the D12. They are indicated by a question mark (?) as shown opposite.

The digital inputs are supervised for correct synchronization with the input signal. Short term interruptions or loss of quality are indicated by flashing ISP-LEDs together with the message "sync?" instead of the detected sampling rate.

If no sampling rate is displayed there is either no input signal or a signal with unusable quality or an unknown (non standard) sampling rate.

Output (Output routing)

Selecting "Output" and pushing the encoder allows the setting of the following output configurations

1.Dual channel

2.Mix Top/Sub

3.2-Way Active

Depending on the selection the corresponding pin assignment of the loudspeaker output connectors will be set automatically.

Note: After a change of the output configuration the D12 outputs are muted. Use the respective MUTE A or MUTE B switches to unmute it.

A detailed description of the D12 output configurations is given in the D12 Hardware manual, which is also supplied with the D12 Amplifier.

Channel A (B)

For both Channel A and B the functions and submenus (menu structure) are similar. Therefore "Channel B" is stated in brackets (B).

Selecting "Channel A (B)" and pushing the encoder enters the submenu "Setup Channel A (B)".

Setup Channel A (B)

Source (Input routing)

Within the submenus "Channel A" and "Channel B" the input source for the respective channel can be selected.

Selecting "Source" and pushing the encoder allows the setting of the following routings:

Input A: The respective channel is fed from input A. Input B: The respective channel is fed from input B.

Input A+B: The respective channel is fed from input A+B. (Input A+B are summed with a 6 dB attenuation)

The status of the selected input source is displayed in the settings menu as shown in the graphics opposite.

Notes on the digital AES/EBU input Input routing:

According to the AES standard (AES3-2003 - Stereophonic mode) the AES channels are assigned to the D12 controller as follows:

D12 Channel A: AES left or A channel (subframe 1) D12 Channel B: AES right or B channel (subframe 2)

Speaker

Speaker Selection

Selecting "Speaker" and pushing the encoder enters the submenu "Speaker Selection" which enables the selection of loudspeaker setups for applicable d&b loudspeakers, depending on the selected output mode.

On the right hand side the software version of the selected speaker configuration is displayed.

A change of the loudspeaker type has to be confirmed. This can be done by selecting "Ok" or "+Clear". Both are marked by a flashing question mark (?).

Ok

Selecting "Ok" and pushing the encoder confirms the configuration and exits the submenu "Speaker Selection".

+Clear

Selecting "+Clear" and pushing the encoder confirms the configuration and exits the submenu "Speaker Selection" and clears the user settings of this channel. The following operations are executed:

-Reset of configuration switches (Filter_1, Filter_2, Filter_3)

-Reset of Delay (the selected unit will be kept)

-Reset of all EQ settings

-Load and Input Monitoring will be set to “off”

-The respective channel will be muted

Cancel ( Back )

Exits the submenu "Speaker Selection" while the previous configuration remains active.

Filter_1, Filter_2, Filter_3

The name of the filter is displayed on the left of the LCD followed by its status or value and a pictogram or graphic representation of the filter's frequency response.

The type of filters available depends on the selected loudspeaker configuration.

The display [---] indicates that the respective filter is not available for the loudspeaker type selected.

on/off

The schematic change in response is indicated by the pictogram.

[Value] (Filter_3)

"Filter_3" can be set to different values. The schematic change in response is indicated by the pictogram.

Filter_1	Filter_2							Filter_3
Configuration of crossover frequencies	Compensation towards listening							Array-EQ (compensation of coupling
for TOP/SUB,	distance, e.g. HFA, HFC.							effects) CPL
