d&b audiotechnik 40D 4-Channel Amplifier 4x2000W 8 Ohms

แอมพลิฟายเออร์สำหรับงาน Installation d&b audiotechnik 40D 4-Channel Amplifier 4x2400W 4 Ohms, 2000W 8 Ohms, Monitoring display, Color TFT touchscreen, 4.3″ / 480 x 272 pixel, 12 configurable GPIOs (8x GPI, 4x GPO)

The 2 RU 40D amplifier provides the power density required for installation purposes while the powerful signal processing extends the level of functionality of the on-board features.

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 user interface of the amplifier consists a 4.3″ color touchscreen providing comprehensive information of the device configuration and enhanced status monitoring. The DSP integrated within the 40D incorporates comprehensive loudspeaker management, switchable filtering functions as well as user definable equalization and delay capabilities.

The user defineable equalizer features two independent 16-band EQ groups within each channel, providing parametric, notch, shelving and asymmetric filters as well as a graphic EQ (via the d&b R1 Remote control software). The delay capability covers a range of up to 10 s. All loudspeaker specific functions such as CUT, HFA, HFC, THC or CPL are available. The DSP unit of the amplifier has a fixed latency of 0.3 ms.

All functions of the 40D are configured via the d&b Remote network via Ethernet (AES70/OCA). To operate the device, the d&b R1 Remote control software is required. The initial configuration of the network parameters after a factory reset can also be done via web browser.

For applicable loudspeakers, d&b LoadMatch enables the 40D amplifier to electrically compensate for the properties of the cable used to connect the loudspeakers to the amplifier output. This function which covers a bandwidth of up to 20 kHz preserves the tonal balance when cable lengths of up to 70 m (230 ft) are used.

Due to its design LoadMatch does not require additional wires and is therefore applicable with any connector type used. To provide optimum compensation, cable length and cross-sectional data as well as the number of loudspeakers connected to the amplifier channel can be entered on the amplifier.

Features:

• High voltage output suitable for driving applicable d&b loudspeakers, including the KSLi System
• Information-rich monitoring display, including device status, speaker setups, Input and Load monitoring, GPIO status, fault indication and more
• Dynamic range (SNR) digital input 116 dB unweighted
• Enhanced energy saving features (Eco mode)
• Eight GPI and four GPO plus a separate general FAULT connector
• Flexible Fallback structure, ensuring the transmission of a secondary signal when required
• Supports d&b ArrayProcessing which improves tonal balance and coverage across the audience area
• OCA/AES70 protocol for easy integration into third party environments using the R90 Touchscreen remote control
• Broad variety of third party integration including Beckhoff, Q-SYS, Crestron, AMX, MediaMatrix
