XTA – APA-4E8

The APA Series is a powerful processing platform that tightly integrates with its power supply featuring 96k analogue to digital converters not only on the analogue inputs++ but also directly at the speaker outputs, monitoring voltage and current. Inputs and outputs are simultaneously being processed by the DSP, along with data about the mains supply, allowing APA to adapt and correct to keep your music sounding better than ever. It’s not so difficult to add some DSP into an existing amplifier design, but to fully monitor all aspects of an amplifier’s performance from input XLR (or network port) to speaker terminals – that’s a little more involved… The APA Series can do this. We have designed a power and processing platform that tightly integrates with its power supply featuring 96k analogue to digital converters not only on the analogue inputs++ but also directly at the speaker outputs, monitoring voltage and current. Inputs and outputs are simultaneously being processed by the DSP, along with data about the mains supply, allowing APA to adapt and correct to keep your music sounding better than ever. In addition to this adaptive processing, you still have full control over a powerful suite of filtering and protection, including multiple bands of our legendary dynamic EQ, FIR filtering and phase linearisation, ultra-transparent limiting, and all the classic crossover and EQ components traditionally used to set up your system. Add to this a fully flexible matrix with the ability to source audio either locally from AES or analogue inputs++, or via a networked audio connection (Dante/AVB). With PC remote software also available, you’ll understand why we don’t think this is just an amplifier with some DSP built in… ++AES and analogue inputs standard, network audio inputs is a retro-fit option

Marani – MDA4-2000PS

MDA4-2000PS is a highly flexible, powerful and intelligent 4-Channel power amplifier delivering up to a total of 4x1700W @ 4 ohms and 4x2320W @ 2 ohms, or able to drive 70V Constant Voltage Lines. MDA4-2000PS is a highly flexible, powerful and intelligent 4-Channel power amplifier delivering up to a total of 4x1700W @ 4 ohms and 4x2320W @ 2 ohms, or able to drive 70V Constant Voltage Lines. Designed to meet the most demanding portable and fixed installation sound systems, it provides a full set of value added features such as high output power, efficient cooling system, on board DSP and USB/Ethernet for monitoring and control via PC software. MDA4-2000PS includes a highly efficient Switch Mode Power Supply, which provides power to the output stages. The 4 output stages use the well-proven Class D module-full bandwith PWM modulator obtaining ultra low distortion, high efficiency and also equipped with a full set of circuit protections. Furthermore the Clip/Limiter function provides output monitoring to prevent speaker damage with gentle gain reduction at clip threshold, in addition to the efficient heat dissipation system and Over-Heat protection which themselves ensure uncompromised reliability. MDA4-2000PS is more than just an amplifier. It is also a capable and sophisticated loudspeaker processor, thanks to its powerful MARANI® DSP running 96 kHz / 24 bit [ 96 bits precision for the internal intermediate processes] and high performance 24bit AD/DA Converters. It offers 4 channels of slope up to 48dB/Oct IIR HP/LP crossover filters, or up to 512 taps FIR filters[FIR coefficients can be imported as .txt/.csv file from external application] , RMS compressor, parametric Eqs , alignment delay and white/pink noise internal generator, everything needed to optimize a loudspeaker system.

Dynacord – PowerH 5000

The power amp H5000 is part of Dynacord’s new PowerH SERIES, which marks a milestone in the design and the production of high-performance power amplifiers.  The power amp H5000 is part of Dynacord’s new PowerH SERIES, which marks a milestone in the design and the production of high-performance power amplifiers. The innovative 3-stage Grounded Bridge Class H Topology with “floating” switching power supply unit offers very high and stable output with extreme high efficiency on an extremely high performance level at minimum weight. PowerH amps are ideal for driving professional touring, high-end Concert-Sound and Pro-Sound applications. Next to classical protections, this new design employs the multi-stage ATP system (Advanced Thermal Protection) for the first time, which in most cases prevents the power amplifier from switching off when the temperature exceeds a critical level. The newly designed MCS system (Mains Current Supervision) prevents power amplifier breakdown caused by the activation of the automatic circuit breaker. For this, among other things, the MCS system uses the highly precise measurement of the RMS value ofthe actual mains current consumption. Information about the status of the power amplifier and its internal protections is provided on a LC-display. By utilizing the optionally available remote control module that is compatible with IRIS-Net™, this power amplifier additionally offers comprehensive remote monitoring and remote control functions plus a universal 2-channel digital audio controller (DSP) including highly precise FIR-filtering and digital speaker protection algorithms.
