Critical path

2x w @ 4 ohms Precision, pure natural sonic performance and total power define the Vortex series. The difference; total care about audio design and integrity. Pure Sonic Performance Total precision and transparency is the trademark of the Vortex series, thanks to its careful design eliminating sound-deteriorating drawbacks right from the start. This is also evident in the Vortex Series exceptional low distortion values and excellent signal to noise ratio. Flexible in Power & Application The Vortex amplifier can easily switch between applications and speaker setups due to its unique power regime. This consists of an extensive power reservoir, stability down to 1 Ohm loads and the ability to run in Stereo, Bridge Mono and Parallel Mono operation modes. Designed for Touring & More With a weight of just 12,4 kg and designed for the demands of touring professionals the 2 RU chassis ensures exceptional reliability. All dynamic protection circuits are the result of the philosophy, “Audio-at-all times”. The Vortex series boasts a huge power outputs throughout the range and has all the sonic qualities that you expect from a Fuzion product. Critical listening tests have revealed that this amplifier really is a force to be reckoned with. Good, well controlled, bottom end performance coupled with sparkling high end and even the heaviest unit only weighs in a little over 12kg! All Vortex amplifiers feature microprocessors that control and monitor internal housekeeping tasks and have a unique 3-stage switch-mode power supply which ensures true wideband output power delivery unlike other designs that tend to sound light on low-end performance. Front panel attenuators are linked to a 12bit digital attenuator, thus removing all audio from the controls themselves. Useful if you've ever experienced crackling control syndrome! Efficient cooling is achieved through the use of two varispeed fans pushing air (from front to back) through a specially designed tunnelled heatsink offering a massive cooling area for the output devices ensuring good thermal stability from front to back across the heatsinks. As the amplifier was designed from the ground - up, all normal failure modes have been designed out. All critical components have purposely been kept out of the air-flow path to ensure that they are kept free of dust and muck. As a further protection against airborne contaminants, the main circuit board is mounted upside down - the muck just falls off ! All protection circuits respond only when damage to the amplifier can be expected, and hence allow for temporary extreme situations without affecting the sound quality of the music program. Vortex 4 is the general purpose popular choice. Ample power is available for most systems Vortex 4 Specifications: * Stereo Power 8 Ohms = 920W / ch * Stereo Power 4 Ohms = W / ch * Stereo Power 2 Ohms = W / ch * Bridge Power 8 Ohms = W (mono) * Bridge Power 4 Ohms = W (mono) Dimensions: mm Weight: 12.4Kg

Rotel RSP 1582 - Processor Our flagship surround processor has been designed for highest performance and maximum flexibility.The RSP-1582 has been two years in the making and is a wholly new platform. Rotel engineers evaluated painstakingly every circuit design and feature requirement. It is built with a modular construction to facilitate upgrades of key internal circuit boards, and is software updateable over the Internet or via a simple USB download if a network connection is not available.The RSP-1582 is a home theater preamplifier/processor, of course, but first and foremost, it truly shines as an audio component. For example, six Wolfson 24-bit/192kHz devices are arrayed as four independent DACs for Front Left, Front Right, Center and Subwoofer channels with shared stereo DAC's for the rear channels. This topology offers exemplary performance all around, but provides the absolute best quality on the most critical channels. In theater mode, a Texas Instruments Aureus DSP high-performance decoder is utilized with 10-channel Parametric Equalization. A high performance Texas Instruments Analog-to-Digital convertor is used to facilitate optimum conversion of analog signals for playback in surround sound modes. Balanced XLR and single ended connections are offered, and the audio stages use premium components in all signal critical applications. For pure stereo playback of analog sources, the RSP-1582 features an analog bypass to obtain the cleanest path.For video use, the preamp/processor incorporates eight HDMI 4K video inputs (no scaling) with two HDMI 4K video outputs. The RSP-1582 also employs a Silicon Image 2K/4K HDMI transceiver. Its modular HDMI circuit construction means future upgrades can be accommodated easily.Other features include one front panel HDMI input with 4K video pass-through, built-in aptX Bluetooth technology, a PC-USB input that supports 24-bit/192kHz audio, CD, Tuner and 4 AUX analog inputs, along with a multichannel input and XLR input. It even has a phono stage!There is a seven-inch TFT display on the front panel to provide easy adjustments to all audio and video parameters without the need to turn on an external display or video projection system — perfect for when the equipment rack is remote located. And the RSP-1582 comes with rack ears in the box to make such installations easy.In addition to its unassailable audio and video performance, custom installers will find the RSP-1582 ideal for any installation application with RJ45 network connection, Internet or USB front panel software updates, three source independent trigger outputs, a wired IR remote input, RS232 and IP interface for automation system control, 2 x IR output connectors for IR pass-through and front panel setup navigation control.All of these features and technology mean nothing, though, if the end result doesn't meet your performance expectations. That's why Rotel engineers spend countless hours measuring, listening and refining the circuitry. The end result is a surround processor/preamplifier that is worthy of the finest music systems and theaters at an unrivalled price. Engineered with care.

Unlike other solutions which depend on separate circuits to address different problems, A-Guard was developed as centralized solution where all protection requirements work together in perfect harmony. A-Guard is only applied when it's necessary to protect the amplifier. This is why VA series amplifiers are able to sustain full power output even under complex capacitive loads. AUDIOCENTER Smart Overheat Management gives VA series the ability to perform in high temperature environments without thermal shutdown. This unique circuitry monitors the amplifier's temperature in real time and when the safe operation of the amplifier is compromised, the output power is reduced but not shutdown. After many hours R&D research, AUDIOCENTER has created new circuitry to eliminate the Class H cross switching distortion. We have done this by the accurate time alignment compensation on the Critical switching path. The result is the same low distortion as Class AB.In fact, all VA series amplifiers enjoy less than 0,1% THD at 16KHz, half power. That's why the sound of the VA series is so clean and natural. We call it Class H+ and it's only available in AUDIOCENTER amplifiers. The advantages of Class H+ can be seen and measured in real world. Phase and Frequency response performance are close to perfect and we clearly lead the category, thanks to our Class H+ topology. ● With a slew rate of 25V/us, VA series amplifiers are among the fastest in the market. ● AUDIOCENTER A-Guard input overload limiter is efficient up to 9V, when many competitive circuitries are over-driven above 3V.
