Product Overview

2 RU 4-Channel Amplifier

The 2 RU, four channel 10D amplifier is designed for permanent integration with applications that require lower Sound Pressure Level (SPL) capabilities. This device contains extended input management functionalities with separate Input Gain control for each input channel, General Purpose Inputs/Outputs (GPIO) and a General Fault connector. Enhanced system status monitoring functions such as Input and Load monitoring ensure suitability in an emergency situation.

The 10D shares the same Digital Signal Processing platform as the latest generation of four channel d&b amplifiers, providing configurations for smaller d&b loudspeakers as well as a linear mode. For larger applications comprising the J-Series, V-Series, B1-SUB, B2-SUB, the M2 monitor and systems which require a higher SPL output, the 30D installation specific amplifier is required.

The DSP integrated within the 10D incorporates comprehensive loudspeaker management, switchable filtering functions as well as user definable equalisation and delay capabilities. This includes two 16-band equalisers, providing optional parametric, asymmetric, shelving or notch filtering and up to 10 s (= 3440 m/11286 ft) signal delay, all of which can be applied independently to each channel.

The 10D is accessible via the d&b Remote network, either via Ethernet using the Open Control Architecture protocol (OCA) or CAN-Bus using RJ45 connectors. The 10D is controlled using the integrated web interface, which enables access via a browser, or using the d&b R1 Remote control software. The device itself contains LEDs to display power, input, data and mute status.

The LoadMatch function integrated within the 10D amplifier electrically compensates for the properties of loudspeaker cable used. The 10D incorporates Class D amplifiers utilising a power supply with active Power Factor Correction (PFC) suitable for mains voltages 100 V/127 V, 50 – 60 Hz and 208 V/240 V, 50 - 60 Hz and maintains a stable output when used with weak or unstable mains supplies. Input and output connectors are all Euroblock sockets.

Input routing
The 10D and 30D amplifiers provide four analog inputs, four digital AES/EBU channels through two inputs as well as separate analog and digital links, all on Euroblock connectors. The digital input pairs contain independent Sample Rate Converters. Each input features a separate input gain, meaning sources with various output levels can be used without requiring an external mixing device. All eight individual inputs can be used simultaneously, then summed and routed to any of the four outputs.

System status monitoring
d&b amplifiers incorporate specific functions to check, monitor and control a d&b system in a specific installation scenario. The System check feature can verify the status of a complete reinforcement system by measuring the impedance of the connected loudspeakers. Each driver in the system is checked and compared to the default impedance values for each particular cabinet. This calibration ensures that each loudspeaker performs within a tolerance band, and indicates possible damage to system components. The Input monitoring function can detect an incoming pilot signal regardless of whether this input is routed to an output. The Load monitoring function can detect a possible loudspeaker malfunction. This feature automatically checks load impedance to calculate individual driver status and report any failure.

GPIO and General Fault Contact
The d&b installation amplifiers incorporate separate Euroblock connectors for General Purpose Input / Output (GPIO) and a fault contact. The GPIO connector offers five pins providing additional digital control lines which can be configured to be either an input or output. This enables the use of external devices to control and detect certain functionalities within the 10D and 30D amplifiers. The GPIOs can be configured to Power the device, mute individual or all channels, change the AmpPreset or to check the Mains Voltage, Power or individual channel status. The separate fault contact allows a general device error to be remotely indicated.

Integrated web interface
The D20, D80, 10D and 30D amplifiers feature an integrated web interface to control individual amplifiers via a standard web browser. In small applications, this allows direct control of each device without the need to create an R1 Remote control software file. The amplifier and the computer must be connected to an Ethernet network. Using a wireless access point, these d&b amplifiers can be controlled using mobile devices.
