d&b audiotechnik 30D Four Ch Installation Amplifier 4x1600W 4 Ohms

เพาเวอร์แอมป์สำหรับงาน Installation d&b audiotechnik 30D 4-Channel Amplifier 4×1600 W 4 Ohms, Digital Signal Processing 2 x 16-band PEQ/notch/shelving/asymmetric, Sampling rate 96 kHz/27 Bit ADC/24 Bit, All Current d&b audiotechnik loudspeakers Setup

The 2 RU, four channel d&b audiotechnik 30D amplifier is designed for permanent integration with applications that require medium to high 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 30D shares the same Digital Signal Processing platform as the latest generation of d&b amplifiers, providing configurations for all d&b loudspeakers as well as a linear mode.

The DSP integrated within the 30D incorporates comprehensive loudspeaker management, switchable filtering functions as well as user definable equalization and delay capabilities. This includes two 16-band equalizers, 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 30D 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 30D 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 30D amplifier electrically compensates for the properties of loudspeaker cable used. The 30D incorporates Class D amplifiers utilizing 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.
