1. Introduction This manual describes the structure, access (user interface) and functions of the firmware of the d&b D12 Amplifier. A detailed description of the D12 hardware and technical specifications is given in the D12 Hardware manual, which is also provided with the D12. A number of publications with supplementary information on our products are available from the documentation section of our website at www.dbaudio.com.
2. The D12 operating software 2.1 D12 menu tree The menu structure of Channel A is shown in detail. The same structure applies to Channel B. The settings for the configuration switches Filter_1/_2/_3 are dependent on the loudspeaker configuration (please refer to section ⇒ Filter_1, Filter_2, Filter_3 on page 11).

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.
2.3 D12 D12 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. d&b audiotechnik D12 V 2.xx The transition to the Main screen is carried out automatically.

It contains general settings for the device and gives further access to submenus. analog Dual channel Q7 Q-SUB off off Press 2s 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.
Output (Output routing) Settings Back Input Output Id0.01 analog Dual channel 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.
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".
Equalizer Equalizer off A 4-band parametric equalizer providing optional Boost/Cut (“PEQ”) or Notch filtering is available for each channel independently in the signal path before the limiting circuit. The EQ function has a Master on/off while each of the four bands can be switched independently. In Dual channel or Mix Top/Sub mode the EQ sections of both channels can be linked using the "Link A»B" function in the "Settings menu".
Notch function F Q G The following parameters can be edited: 3 Notch A 3460 Hz 25.00 BW 0.04oct ------- F Filter center frequency adjustable from 20 Hz to 20 kHz in 3 % steps. Q The Q of the filter is adjustable from 0.5 ... 25 in 10 % steps. In addition, the bandwidth (BW) as a result of the Q is displayed as a value (2.0 ... 0.04 octaves) in a non-editable field. G The parameter "Gain" (G) cannot be edited in "Notch" mode. The center frequency is fully attenuated (⇒ –∞ dB). Delay Delay off 0.
Impedance Z The impedance of the loudspeaker(s) presented to the output of the D12, displayed only as a numeric value in ohms. The value is measured with the actual output signal and may therefore vary with its spectral content. The measurement range reaches from 0 ohms (short circuit) to 255 ohms (open loop, I = 0, Z ⇒ ∞). When the signal is too low the maximum of 255 ohms is displayed.
System Check System Check is a powerful and convenient tool to check the condition of either a single d&b loudspeaker or a complete d&b sound system driven by the D12. It is preferably used in conjunction with the d&b Remote network and the R1 software. System Check uses the amplifier's capability to measure the impedance connected to its outputs using a sine wave signal created by the DSP section of its controller. System Check is related to the Load Monitoring feature of the D12.

Level Level of the frequency generator in dBu covering a 63.5 dB range from –57.5 dB to +6 dB in 0.5 dB steps. The level value corresponds to the level at the controller signal input. The actual output voltage depends on the channel input gain, the frequency dependent gain of the selected loudspeaker configuration and EQ settings if used. Frequency Frequency adjustable in the range of 1 Hz to 20 kHz in 1 Hz steps.
AmpPreset D12 amplifiers from firmware version V2.12 provide AmpPresets which contain all important user settings of the entire device such as input, output and channel configurations, EQ and delay settings. Using the D12 AmpPresets a sound system can be operated in different configurations (e.g. "Conference", "Music" or "Emergency Call") without the need of transmitting all detailed settings of the devices used.

Input Monitoring According to the European Standard EN 60849 "Elektroakustische Notfallwarnsysteme" (equivalent to international standard IEC 60849 "Sound Systems for Emergency Purposes") the complete signal chain needs to be monitored. Therefore the "d&b Input Monitoring" functionality allows the detection of an incoming pilot signal to be inserted into the signal chain in front. Important notes on Input Monitoring Input Monitoring can supervise the D12 analog or digital inputs.

2.5 Display messages 2.5.1 Error messages Error messages can be related either to the device ("Device") or to a single or both channels of the device ("Channel"). Channel related error messages are supplemented by the channel information. Device System Error [nnn]: an internal fault has occurred. Switch the device off and on again (reboot). The number [nnn] can provide your d&b service partner with information on the cause of the fault.
Channel Amp. Temp. Warn. ([xx] °C): the temperature of the heat sink is very high, the air flow should be checked (fan filter) or the load should be reduced. Channel Amp. Overtemp. ([xx] °C): the temperature of the heat sink is too high and the device is muted and the loudspeaker output is switched off. After cooling down to a permitted operating temperature the device will switch on automatically. Channel Amp. Temp Err. ([xx] °C): the temperature of the heat sink of the device is too high.
2.5.4 Further messages The following messages are intended for information on the status of the D12. They are no error messages. Standby: indicates that the device is in standby mode. Unlock: Press knob 2s: indicates that the device has been locked to protect it against accidental or unauthorized operation. Press and hold the encoder for a minimum of 2 seconds until "Lock" disappears from the lower status line of the LCD. 2.
3. D12 Firmware update Note: A firmware update erases all user settings of the device. The device name and the log files are kept. The operating software – firmware – can be updated in two different ways. 1. Firmware update of a single amplifier via serial interface using the dbUpdate software program. 2. Firmware update of multiple amplifiers via the d&b Remote network (CAN-Bus) using the R10 Service software. In addition, the d&b Firmware Installer is required.
