D&B AUDIOTECHNIK | D6 / D12
www.dbaudio.com
The d&b audiotechnik D6 and D12 are two-channel power amplifiers specifically for use with d&b loudspeakers; digital signal processing is incorporated, as are analogue and digital signal inputs as well as links outputs. d&b loudspeaker specific controller functions are imple- mented within the DSP, and both channels have independent user definable four band parametric equalisers providing optional boost/cut or notch filtering. The signal delay capability allows delay settings of up to 340 milliseconds to be applied independently to each channel. The D6 and D12 amplifiers can deliver 600W or 1,200W into four ohms per channel respectively, while the switch mode power supply au- tomatically selects the mains voltage. d&b load monitoring enables automatic and continuous impedance monitoring, while system check is designed to verify that the system performs within a predefined condition and can be used to report the system condition after the show. The D12 also integrates d&b SenseDrive resulting in a precise bass performance. All settings within the D6 and D12 can be accessed with a rotary encoder and LCD display or via the d&b remote network. The remote control interface enables control and monitoring of system functions from other multimedia environments.
DYNACORD | DSA 8410
www.dynacord.com
Along with the DSA 8405 and DSA 8805, the DSA 8410 features very high output, a high degree of efficiency, and the ability to integrate with IRIS-Net. The DSA 8410’s Variable Load Drive (VLD) technology makes it uniquely flexible. Each of the four channels can be individually configured to deliver a maximum power of 1,000W into any load from two up to 10 ohms, or drive 70 or 100V loudspeaker lines directly without an output transformer. Other models of the DSA multi-channel amplifier series comprise four 500W output power (DSA 8405) and eight 500W output power (DSA 8805). When equipped with the RCM-810 module, users can configure each of the DSA multi-channel amplifiers via IRIS-Net software. In addition to state-of-the-art technology, DSA amplifiers exhibit robustness, the highest production quality, and a host of practical features, including level controls on the rear panel and power remote via a contact closure.
EQUIPSON | DCA 1
www.equipson.es
The DCA 1 from Equipson’s Work brand is a versatile mixing amplifier with digital audio matrix (8-in/2-out). It can be remotely controlled from a third party controller (RS 232/485 vía ASCII or DMX) or directly from a mobile device (iOS or Android) thanks to the OSC open protocol. It features two amplified output zones (120W RMS per channel) and eight mono inputs. Thanks to its microprocessor, it is possible to set up a digital matrix mixer and control each zone independently or it can be used as a two zone amplifier with remote control input and volume. Thanks to the RS 485 port, it is possible to use four DMX channels to set up the output gain and select the audio source of each output. This all-in-one solution is especially adapted to installations like restaurants or small shops, taking into account that it can easily integrate itself into an existing network managed by a third-party controller.
FULL FAT AUDIO | FFA-4004 / 6004
www.fullfataudio.com
The FFA-4004 and FFA-6004 four-channel amplifiers feature onboard DSP, have two inputs which can accept AES digital or analogue signals and unusually, feature six outputs which drive the four amplifier channels and two auxiliary XLR outputs, allowing connection to an adjacent stereo bass amplifier or any other amplifier that requires a processed input signal. The DSP is controlled using an Ethernet connection on the rear of the FFA-4004 or FFA-6004. This connection to a PC or Mac using Cat 5, a switch or wireless router allows the user to control the amplifier using simple to use software. Multiple units can be networked together to build larger systems. The user can design audio systems with a tool box that contains all the filters and features such as parametric EQ, limiter, delay, gain, phase that are expected in a modern loudspeaker management system. A useful compressor limiter on the inputs and outputs is also included. The DSP amplifier has voltage-controlled amplifiers for each output channel which are accessible by a port on the amplifier rear. Each audio output can be remotely volume controlled by a simple wall mounted potentiometer.
