2.2 User interface

CUT

Q-SUB

The LCD [4] acts as a user interface for all of the menus within the D6. The cursor is controlled via the digital rotary encoder, LEVEL/PUSH MENU [3]. In the main menu the encoder acts as a level control. Pushing or turning the encoder gives access to different menu levels or allows configurations or values to be entered.

Also refer to the D6 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.

2.3 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.

2.4 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.

Starting from the second line the main menu of the D6 is split into channel A and B and the following settings and information are displayed:

- loudspeaker setups (Speaker type)

- input gain

- status of the delay and

- Link A»B.

The lowest line shows the status or value of the following settings for both channels:

- Filter_1, Filter_2, Filter_3 (value)

- EQ

- In the center of this status line the dbCAN-Id (if remote mode dbCAN is selected) or the remote mode (if not dbCAN) is displayed. Please refer to the Remote menu section on page 20.

Using the encoder (LEVEL/PUSH MENU) the input gain can be adjusted in steps of 0.5 dB (–57.5 dB to +6 dB). A brief press on the encoder changes between level control of channel A and B.

If an error occurs (the red OVL/Err-LED flashes), an error message with channel information will alternate with the device name in the top line of the LCD.

In Standby Mode, the display alternates between the device name and “Standby”.

A long press (1 s) on the encoder enters the Settings menu.

The Settings menu 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 dbCAN-Id is given in the Remote section on page 20 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 D6. 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 signal with unusable quality or an unknown (non standard) sampling rate.

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)".
