3:4.About the amplifier platform
K Series has many advanced features, digital control of many parameters, adjustable maximum m ains consumption, selectable digital presets and a graphic display that shows detailed information of the status of the amplifier. All K Series amplifiers come with built in Power Factor Correction. This unique feature ensures that a predominantly resistive load is presented to mains thus minimizing current distortion and voltage/current displacement. This leads to improved performance of the amplifier at high levels of output and avoids mains-voltage collapses, typical of standard and switching power supplies. Another great advantage of this technology is that its performance is, to a large extent, independent of mains voltage. The rated output power does not vary with load/line conditions.
3:4.1.More sound and less weight
Class D technology based amplifiers are highly efficient, delivering greater power to speakers with reduced heat dissipation: typical running efficiency of output stages is 95%, with only 5% of input energy dissipated as heat. This allows for smaller dimensions, weight and power consumptions.
Contrary to conventional amplifiers which achieve highest efficiency only at full rated power output, Class D efficiency is almost independent of output level. Music has an average power density of 40% of its peak value; this means that other (non-class D) amplifiers can easily generate 10 times more heat than Powersoft products for the same sound pressure level.
Powersoft amplifiers deliver crystal-clear highs, and a tight, well-defined low end: the most accurate reproduction of an audio signal. Solid time proven design features ensure extremely high performance in terms of super low total harmonic distortion, optimal frequency response, high power bandwidth and damping factor across a vast number of application scenarios. Powersoft’s multi patented application of Pulse Width Modulation (PWM) high frequency sampling techniques is just one of the many factors contributing to the K Series’ high performance ratings across the audio bandwidth.
3:4.2.The Show Always Goes On
The K series offers complete protection against any possible operation error. Every amplifier in this series is designed to work under a large range of possible conditions, delivering maximum power with maximum safety and an outstanding long term reliability. Anticipating potential problems at the design stage means your show always goes on!

Installation |

|
The common installation of the amplifier is in rack cabinets: in order to limit the risk of mechanical damages, the amplifiers must be fixed to the rack using both frontal and rear mounting brackets.
Note: Instead of connecting the amplifier to the power grid directly, plug the amplifier’s mains connections to a power distribution panel inside the rack cabinet.
Mounting
Brackets
FIGURE 4: Mounting brackets and air flow direction.
6:1.Cooling
Install the amplifier in a well-ventilated location: the ventilation openings must not be impeded by any item such as newspapers, tablecloths, curtains, etc; keep a distance of at least 50 cm from the front and rear ventilation openings of the amplifier.
All Powersoft amplifiers implement a forced-air cooling system to maintain low and constant operating temperatures. Drawn by the internal fans, air enters from the front panel and is forced over all components, exiting at the back of the amplifier.
The amplifier’s cooling system features “intelligent” var- iable-speed DC fans which are controlled by the heatsink temperature sensing circuits: the fans speed will increase only when the temperature detected by the sensors rises over carefully predetermined values. This ensures that fan noise and internal dust accumulation are kept to a strict minimum.
Should however the amplifier be subject to an extreme thermal load, the fan will force a very large volume of air through the heat sink. In the extremely rare event that the amplifier should dangerously overheat, sensing circuits shut down all channels until the amplifier cools down to a safe operating temperature. Normal operation is resumed automatically without the need for user intervention.
X Series amplifiers can be stacked one on top of the other due to the efficient cooling system they are equipped with.
There is however a safety limit to be observed: in case a rack with closed back panels is used, leave one rack unit empty every four installed amplifiers to guarantee adequate air flow.

6:2.Cleaning
Always use a dry cloth for cleaning the chassis and the front panel. Air filter cleaning should be scheduled according to the dust levels in the amplifier’s operating environment.
Disconnect the AC main source before attempting to clean any part of the amplifier
In order to clean the vent filters you need to remove the front cover: never attempt to open any other part of the unit.
By means of a screwdriver Phillips PH1, unscrew the screws that lock the left and right cover grils on the front panel (ref. FIGURE 6), gently lift the covers and remove the filters. You may use compressed air to remove the dust from filters, or wash it with clean water: in the latter case ensure that the filters are dry before reassembly.

6:3.AC mains supply
The AC Main connection is made via the
ffAMP CPC 45A connector in K6, K8, K10 and K20;
ffIEC C20 connector in K3 and K2.
The FIGURE 7 shows how to connect the mains power cable to the amplifier.
Make sure the AC mains voltage used is within the acceptable operating voltage range: 115V-230V ±10%.
It is important to connect the ground for safety, do not use adapters that disable the ground connection.
All K Series amplifiers have an automatic power factor correction system – PFC – for a perfect mains network interface. The PFC minimizes the reactive power reflected on the network and reduces the harmonic distortion on the voltage/current waveform: in this way the amplifier is seen as a resistive load from the mains network. Furthermore, the system allows performance to be maintained even in case of varying mains voltage.
Connection to the mains shall be done only by a electrotechnical Skilled person according the national requirements of the countries where the unit is sold
