Class power amplifiers

The new MP Series of power amplifiers from Wharfedale Professional are the latest addition to the expanding range of Wharfedale Professional electronics. Built to last, the MP amplifiers are designed to withstand the rigours of life on the road and last a lifetime in professional installation. Sonic accuracy and durability are the most important features of your power amplifier. You need to be able to rely on your amplifier to perform time after time, giving the best reproduction of sound again and again. You can be sure of this with your MP Series power amplifier from Wharfedale Professional. Not only have they made sure the mechanical engineering is the best, also using an all steel chassis, but Wharfedale Professional have taken extra care with every single component that they have chosen to go into the unit. When Wharfedale Professional are satisfied, they assemble the amplifiers in there own factory. After passing a vigorous QC process using the most up to date test equipment, the amplifier is then worthy of Wharfedale Professional's guarantee. The MP Series of power amplifiers feature a continuously variable speed fan for optimum cooling. The airflow generated over the copper plated heatsink achieves massive heat dissipation, keeping the output devices evenly cooled throughout operation. The MP Series also features sophisticated protection circuitry - protecting both the amplifier and the speakers connected to it if a fault occurs. The thermal overload protection mutes the input signal when it senses the amplifier is running at unsafe temperatures. The short circuit protection keeps the output devices operating at a safe level even though the circuit itself allows high peak currents. The amplifier also features a Soft Start Protection circuit to avoid 'pops' in power up and power down situations.

In full working condition. Retails for US$ The Samson SX stereo power amplifier has been designed to provide robust, clean output with low distortion and wide dynamic range, along with the dependability demanded by professional audio engineers and installersThe Samson SX Series stereo power amplifiers have been designed to provide robust, clean output with low distortion and wide dynamic range, along with the dependability demanded by the most professional audio engineers and installers.The SX is the most powerful addition in the SX series of amplifiers. Boasting a staggering Watts of Class H power in a two rack space design. The SX is a perfect solution for driving professional audio systems of any size. The SX Amps are built around a new power core design with over-sized toroidal transformers and extra-large heat sinks. The amps maintain cool operating temperatures thanks to an innovative forced-air cooling system with temperature sensitive variable-speed fans.Trouble free operation is provided by multi-stage protection for power-up, over-heating, over-current, short circuit, low output impedance and DC voltage, assuring total reliability under the most demanding conditions. The entire SX line is 2 Ohms stable and features locking XLR/TRS inputs, Speakon® and 5-way binding post speaker outputs.Features:• Professional High Power Rail-switching Amplifier• 800 Watts per side @ 8 Ohms• Watts per side @ 4 Ohms• Watts bridged mono @ 4 Ohms• Dual Variable-speed Fan Cooling• Signal, Peak, and Protection Circuit Indicators• 5-way Binding Post and Speakon™ Speaker Outputs• XLR and TRS Input Connections• Dual Rack Space DesignHighlights:• Clean, crisp sound - Impressive audio specifications such as 0.04% THD, dynamic range of 105 dB, crosstalk of 80 dB, and frequency response of 10 Hz to 55 kHz guarantee ultra-clean sound quality.• Independent input level controls for each channel allow precision adjustments.• LED signal indicators for each channel continuously display power output levels and allow you to correct for overloading (clipping) conditions.• Unique stable bipolar circuit design that continuously keeps DC output during idling at or near zero volts (thus keeping idle speakers at their zero point). This serves to minimize heat overload problems by effectively preventing the SX Series from applying power when unnecessary.• Forced air cooling via two temperature-sensitive, variable speed fans provides reliable performance without thermal and overheating problems.• Protection relay circuitry (with dedicated LEDs for each channel) that guards against overheating or faulty wiring conditions and also prevents “thumps” when powering on or off. This means that you can use the SX Series with a single power strip into which a mixer or other audio devices are connected, without danger of damage to connected speakers.• Combination input connectors for each channel accommodate both balanced XLR or balanced 1/4-inch TRS plugs.• Output connections are made via 5-way binding posts and Speakon™ connectors.• Toroidal transformer power supply for high current and low profile.• User-resettable circuit breaker for fast, easy startup following a power supply overload.• The SX Series can be mounted in any standard 19" rack (taking just two rack spaces), making it easy to integrate the amp into any fixed or traveling PA rig.• Rugged construction (an all-steel chassis with a cool gray finish and a lightweight anodized aluminum heat sink) makes the SX Series eminently roadworthy.• Last but certainly not least, value. The Samson SX Series has been designed from the ground up to deliver excellent sound.

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.

This range of four channel power amplifier is Class-D series, which built four separate amplifiers into a single chassis.
