3 : 1.Welcome

Congratulations on buying a Powersoft K Series amplifier!

We know you are eager to use your new amplifier, but please take a moment to read this user’s manual and safety instructions. In case you have any questions, please do not hesitate to contact your dealer or Powersoft.

Powersoft is a leading company in the field of high efficiency audio power management. The Powersoft switching mode technology has changed the way the world looks at professional audio amplification: no other amplifier’s performance comes close for applications demanding high power and long term reliability. Thanks to amazing reductions in heat output and weight, without sacrificing output powers, Powersoft amplifiers can be used in an unlimited range of PA applications such as opera houses, theaters, churches, cinema, and theme parks.

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 : 2.Unpacking & checking for shipping damage

Your Powersoft product has been completely tested and inspected before leaving the factory. Carefully inspect the shipping package before opening it, and then immediately inspect your new product. If you find any damage notify the shipping company immediately.

The box contains the following: f f f f f f

3 : 3.Disposal of the packing material

The transport and protective packing has been selected from materials which are environmentally friendly for disposal and can normally be recycled.

Rather than just throwing these materials away, please ensure they are offered for recycling.

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 1: Mounting brackets and air flow direction.

4 : 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” variable-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.

FIGURE 2: How to stack the amplifiers in closed racks.

4 : 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 3

), 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.

4 : 3.AC mains supply

The AC Main connection is made via the f f f f

The

FIGURE 4 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

Connections

Make sure the power switch is off before attempting to make any input or output connections.

By using good quality input and speaker cables, the likelihood of erratic signal behavior is reduced to a minimum.

Whether you make them or buy them, look for good quality wires, connectors and soldering techniques.

5 : 1.Signal grounding

There is no ground switch or terminal on the K Series amplifiers. All shield terminals of input connections are directly connected to the chassis. This means that the unit’s signal grounding system is automatic. In order to limit hum and/or interference entering the signal path, use balanced input connections.

In the interests of safety, the unit MUST always operate with electrical safety earth connected to the chassis via

the dedicated wire in the 3-wire cable (ref. Chapter 4 : 3.AC mains supply

). Never disconnect the ground pin on the AC mains power cord.

5 : 2.Analog input

Analog input is provided by means of two Neutrik XLR connectors in K2 and K3 or a couple of XLR/jack hybrid combo connectors in K6, K8, K10 and K20 amplifiers (refer to

Panel D, Panel F, p. vi ). Signal polarity for XLR and

TRS plugs is shown in

Panel I, p. x .

5 : 3.Analog line output

Line out is provided in K2 and K3 via a couple of XLR connectors on the rear panel (refer

Panel D, p. iv ). In

DSP equiped models, the output signal is pre-DSP, being a replica of the input signal.

5 : 4.Digital Input

On DSP equiped models, the XLR input for channel 2 can switch to an AES3 digital input. The AES3/analog pushbutton located nearby the channel 2 XLR input connector toggles the XLR between analog and digital input (refer to

Panel D, Panel F, p. vi ).

In AES3 mode f f f f input if the digital input fails.

The AES3 connection carries a channel pair through a

110 Ω nominal impedance wire in the form of a balanced

(differential) digital signal: in AES3 XLR connectors the identification of hot and cold pins is not an issue; take care to never tie pin 2 or pin 3 (balanced signals) to pin 1 (ground).

Avoid the use of microphone cables in AES connections: impedance mismatch can result in signal reflections and jitter, causing bit errors at the receiver.

5 : 5.AESOP

The AESOP standard can transport a single bidirectional Fast Ethernet (IEEE 802.3u, 100 Mbit/s) control data stream and two independent separate AES3 digital audio monodirectional streams using one Cat5 cable.

All K Series amplifier with the optional KAESOP board installed are equipped with at least two RJ45 connectors, each of them being a single AESOP port, capable of sending and/or receiving data and audio.

If the amplifier has only two RJ45 plugs, these will be on the front panel. If four plugs are present, the rear two will be “primary” ports, while the two on the front panel are

“secondary” ports.

Primary ports allow both data and AES3 streams; secondary ports, on the other hand, are data-only ports, allowing Ethernet connections only.

Cat5 standard twisted pair cables shall be used for connections up to 100 meters (328 ft). RJ45 pinout must comply to TIA/EIA-568-B and adopt the T568B scheme pinout, as

show in TABLE 1 .

CLASS2 WIRING

Output terminals are hazardous: wiring connection to these terminals require installation by an instructed person and the use of ready made leads.

Take care to secure the output terminal before switching the device on.

Two Neutrik NL4MD speakON connectors are located on the rear panel, each of them being a single output to loudspeaker (refer

Panel D, Panel F, p. vi ).

Pins 1+ and 2+ are physically bridged to the positive pole; pins 1– and 2– are physically bridged to the negative pole

(refer

Panel J, p. x

).

In order to remain within safe operating conditions, when using low impedance loads – i.e. 4 � or less (8 � or less in bridge mode) –, connections must be made with a four wire cable. Use suitable wire gauges to minimize power and damping factor losses in speaker cables.

5 : 6.1. Bridge-tied load

Bridge-tied load connection can be achieved as described in

Panel J, p. x

. In analog mode, only the input of channel 1 needs to be wired: link channel 2 to channel 1 by means of the link pushbutton located on the rear panel.

When operating with digital inputs – i.e. AES3 and

AESOP – link the channels via software: do not switch the link pushbutton.

5 : 7.V Ext

The V Ext terminal is used to remotely manage the DSP in K Series DSP amplifier and enable remote on/off.

K Series provided with a KAESOP board have a dedicated 2 pin Phoenix connector MCV 1,5/ 2-G-3,81 - 1803426 located near the rear Ethernet ports. K Series with the RS-

485 serial port implement the V Ext connection on pin 2 (pin

7) of the RJ45 rear connector.

When the V Ext port is powered by and external 12 V

DC

(1 A max) power supply, the internal controller allows to control the DSP – if present – even without AC mains supply, and allows serial communication – via RS-485 or ethernet communication in KAESOP equiped models – for remote on/off via the Armonía Pro Audio Suite software.

5 : 8.RS-485 connection

K Series amplifiers without an optional KAESOP board can be remotely controlled via an RS-485 connection.

Remote connection data cables must have an 8P8C modular plug – namely RJ45 plug – to be inserted in the rear port labelled “DATA PORT”.

By plugging an RJ45 plug and selecting the unit’s remote

ID via the rotary trimmers, the amp is ready to be remotely controlled. Please note that ID numer 00 is not allowed.

The recommended arrangement of the connections is a series of point-to-point (multidropped) nodes – i.e. a line or bus. Ideally, the two ends of the line should be terminated with a resistor, typically 120 � for twisted pairs. Powersoft recommend the use of Ethernet Cat5 straight through –

patch

– cables with pin/pair assignments TIA/EIA-568-B,

i.e. T568B (ref. TABLE 1 ).

In all K Series amplifiers, the combination of the front panel buttons together with the LCD display allow the user access to detailed information and complete control over the amplifier’s status. Each button has multiple functions and the display shows the current active function for each button. This chapter illustrates all the functions and settings accessible via the amplifier front panel.

All the setup and settings functions described in this section can be also accessed through a computer with

Powersoft’s Armonía Pro Audio Suite software. Armonía is a software environment that offers an easy to use end user remote control interface and signal processing capabilities.

Armonía Pro Audio Suite is available for free on the

Armonía forum: http://www.powersoft-audio.com/en/armonia-forum

Please note that when an Armonía client is connected to the amplifier, any local operation is overridden by the software.

6 : 1.LED chart

The LED columns on the front of the amp can work as output voltage or current meters. When the LED bars are set to meter output voltage, for example, the meters on the LCD screen will indicate output current values. The vice versa is true: LED bars set as output current meters, LCD display bars become output voltage meters.

Pressing the button directly below the “menu” label on the LCD screen gives access to the amplifier’s main menu.

If an Armonía client is connected to the amplifier, a yellow shadow will appear in the software workspace view, signaling local access to the amplifier.

6 : 2.1. How to navigate the main menu

The K Series main menu can be accessed by pressing the first button on the right, underneath the LCD label

“menu”.

The up and down arrows allow to scroll the menu items.

To access further menu voices branching off a specific menu item, select it and press the “menu” button once.

Some submenus in the K Series amps require the user to set a numerical value for specific parameters using the front panel buttons. In order to speed this process up, these submenus dedicate two of the four available buttons to switching to a fast or slow parameter increment mode.
