Electrostatic Discharge (ESD)

Electrostatic discharge (ESD) is one of the most signicant factors leading to damage and failure of a wide variety of electronic components.

Poor handling can cause internal damage, which is invisible. This internal damage can then cause electrical failure or reliability problems.

It is recommended that all workstations where

Electrostatic Discharge Sensitive devices (ESDS) and assemblies are handled outside of full static protection packaging (i.e. within static control areas) should be provided with some form of ground conductive or dissipative ooring.

M-Drive User Guide

7 : 1.Welcome

Congratulations on your purchase of the Powersoft

M-Drive module.

We know you are eager to use the M-Drive module, 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.

The M-Drive is a one channel amplier modules specically designed to fully exploit the potential of the M-Force transducer. M-Drive shows amazing gures in terms of both output voltage (310 V capabilities (200 A

The new design of the power supply equipped with PFC, reduces power consumption while enhancing reliability and consistency in all operating conditions.

M-Drive can be equipped with any Powersoft or thirdparty DSP solution, and integrates the Powersoft’s patented Differential Pressure Control technology that optimizes sonic performances of the amplier+transducer+cabinet+ environment system.

7 : 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 nd any damage notify the shipping company immediately.

7 : 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.

7 : 4.Differential Pressure Control

The Differential Pressure Control – DPC – is the core technology of the Integrated Powered Adaptive Loudspeaker system, also known as IPAL.

DPC makes M-Drive efcient and reactive to

DIFFERENTIAL

PRESSURE CONTROL

PATENTED

The differential pressure measurement, senses the difference of pressure between the front and the rear sides of the radiating diaphragm and uses this information to alter the behaviour of the transducer, according to the real boundary conditions. Thanks to this innovative approach to full boundary conditions feedback processing, the DPC dramatically improves the electroacoustic efciency in terms of high SPL and sonic performance of the sound reinforcement system.

The DPC system combines a high-efcient transducer with a high-power switching mode amplier that embed a fast and effective ZeroLatency™ DSP. The DSP performs the double operation of both managing the loudspeaker processing and taking care of the differential pressure control signal. M-Drive establishes a global feedback between the electrical and the acoustic domains.

Thanks to the rich graphic user interface – GUI – it is possible to weight and customize the feedback between the electrical and the acoustic domains.

7 : 4.1. Pressure mode

The Pressure mode relies on the DPC making it possible to match a specic target pressure response. Being the SPL output of any acoustic signal derived from the relationship between the pressure and the acoustical impedance, it’s straightforward to use a direct measurement of such a pressure signal to make the system track a reference target pressure model. Benets in terms of predictability of the system response and reduction of sensitivity from disturbing effects could be substantially appreciated.

MIN.

Fans side

This device must be correctly heatsinked for proper and

reliable operation.

The built-in fans and an appropriate external passive heat sink guarantee by design thermal efciency and reliability.

Proper heat sink planarity is strongly suggested to allow thermal transfer from the module’s bottom plate to the heatsink; a thermal compound may be used, but it is not strictly necessary.

In order to ensure proper ventilation of the module, reasonable spacing of at least 100 mm must be left between the frame of the unit and any side component or surface of the enclosure.

The module has been designed to t into a loudspeaker cabinet: please refer to FIGURE 1 for proper module placing.

IN FIGURE 1 HEATSINK FINS ARE SET HORIZONTALLY

(WRONG!) ONLY FOR DESCRIPTIVE PURPOSE.

We suggest to position the module vertically with respect the ground in order to take advantage of the chimney effect for ventilation and heat dissipation.

Here we suggest a rule of thumb to calculate the thermal resistance of the heatsink.

The absolute thermal resistance of the heatsink is the temperature difference (kelvin or celsius) across it structure when a unit of heat energy ows through it in unit time (watt). For seek of simplicity, a heatsink with low thermal resistance offers high heat dissipation, as well as a low electric resistance allows high current ow through a conductive wire.

In order to dene the maximum allowed thermal resistance for the heatsink let assume the following:

 e as the amp module efciency

 cf as the crest factor of the audio signal

 W

as the peak power delivered by the module

Electromagnetic Compatibility (EMC) & Safety

9 : 1.AC MAINS ﬁlter

In order to improve the electromagnetic compatibility an EMC lter must be inserted before the AC MAINS

plugs on the power supply. Powersoft suggests:

9 : 2.Cabling

FIGURE 3: Typical electrical schematic of the EMI Filter.

Wiring between the amp module and the load may lead to radio frequency noise. The following guide lines should be observed:

 reduced cabling length is advisable;  keep cable pairs as close as possible to each other in

order to minimize the antenna effect;

 design the cabling path far from RF noise source;  set the cabling for RF noise rejection: shielded or

twisted cables are advisable conguration (ref.

Wrap both cables around one side of each ferrite so that it pass through each ferrite twice (ref. FIGURE 3). Install the ferrite shield as close as possible to where the cable plugs into the amplier. Placing the ferrite elsewhere on the cable noticeably reduces its effectiveness.

FIGURE 4: Ferrite core installation on I/O wirings.

9 : 4.Chassis shielding

If not already present on the product, a full body metal chassis or a shielding cage will provide best shielding of RF emission. In order to achieve the highest shielding, minimize the amount and size of holes or opening in the chassis.

This device must be powered exclusively by earth

connected mains sockets in electrical networks compliant to the IEC 364 or similar rules. Is absolutely necessary to verify this fundamental requirement of safety and, in case of doubt, require an accurate check by a qualied personal. Is absolutely necessary to ground this device using the proper earth connection on the metal frame of the chassis; use M4 nut and bolt with proper split washer – grover washer – to secure the earth terminal lug.

Hardware protections

The architecture of Powersoft’s ampliers encompass several protection mechanisms triggered by harmful signal and temperature. Protection systems and triggers are independently implemented in the power supply section (power supply protection) and the amplier section (amplier protections). (ref. Chapter 15 : 3.Advance d param eters).

12 : 1.Thermal Protections and Fan Control

Fan starts to run as soon as the amp module measures a temperature greater than 35°*, the fan control keeps fan at maximum speed for the rst 2s, then its speed will be controlled according to operating temperature.

When the amp module reaches 45°**, or when the module reaches the 500 W threshold, the fan starts to run at maximum speed.

At 60o the temperature Led will turn solid on, at 80o the unit will shutdown.

The temperature of the Amplier section is monitored and replicated on the 34 poles interface connector according to the TEMPON table:

12 : 2.Power supply protections

Power supply protections aim to isolate a faulty section in electrical power system from the rest of the device in order to prevent the propagation of the fault and limit device damages.

12 : 2.1. Primary AC mains overcurrent protection

AC main overcurrent are ltered by two 10 A time-lag fuses (also known as time-delay or low blow-fuse). The purpose of the time lag fuses is to allow the supply in electricity for a short time before the fuses actually blow. If the time-lag fuses blow out, the amplier switch off; replace the fuses with proper 10 A time-lag fuses in order to restore the full functionality of the amplier.

12 : 2.2. Primary AC mains overvoltage protection

AC mains overvoltage threshold is set to 295 V AC mains voltage exceeds 295 V working; the device does not turn completely off but falls in a “sleeping” mode: the power supply turns on again when the AC mains voltage drops under 290 V

AC mains overvoltage are well tolerated by the power supply: no damages can be caused to the system even in case of severe overvoltage up to 400 V

the power supply stop

12 : 2.3. Primary thermal protection

The temperature is detected at power supply and triggers the heat dissipated by the device: if the temperature rises exceeding components tolerances, the primary hardware thermal protection starts lowering the rails voltage in order to lower the heat wasted and keep the overall efciency high.

The process is drived by the DSP section of the Control Board and is auto-adaptive, aiming to maintain the system up even in heavy thermal condition.

12 : 3.Ampliﬁer protections

The amplier section protections are managed by the DSP section on the Control Board and can be customized by means of the ArmoníaPlus software.

12 : 3.1. Auxiliary power protections

Auxiliary plugs are protected against short circuit: a poliswitch opens the auxiliary circuits when the current drawn exceeds 1 A.

12 : 3.2. Secondary overcurrent protection

A secundary protection on the load shuts down the amplier section when an output current greater than 200 A is detected.

Initialization

15 : 1.DPC Programming System

The DPC technology represents the most effective tool available for the acoustic designer to achieve unprecedented results in terms of control over the transducer displacement and system performance in low frequencies. Thanks to the differential pressure control, the behavior of subwoofer and low frequency applications can be modeled in order to modify the systems response, increase sound pressure level capabilities and enhance the overall efciency.

A DPC system is composed by:

 Class-D amp module;

 differential pressure sensor;

 Zero-latency DSP board;

 low impedance transducer

The DPC system performs a real time feedback between the actual acoustic emission of the loudspeaker and the instantaneous displacement of the transducer. By knowing the pressure eld generated by the loudspeaker, the Zero Latency DSP controls the transducer displacement and adaptively modify the system emission. The system is capable to overcomes transducers non linearities, offering a complete control over sonic performance. In addition, DSP provides the needed algorithms for a complete loudspeaker tuning.

Using ProManager Plus™ is possible creating a custom model based on Zero Latency DSP (included on M-Drive) or based on an additional Powersoft DSP-4. Once you have created and exported the custom Armonía Plugin, the loudspeaker equipped with M-Drive can be recognized and managed via ArmoníaPlus™ software.

15 : 2.initialization framework

15 : 2.1. Initialization workﬂow

In order to initialize the DSP on board and external Powersoft DSP, the ProManager Plus™ proposes two approaches: Powersoft init or Custom init. The former initializes your DSP with default settings, while the latter initializes the DSP with your custom processing and it will allow ArmoníaPlus™ to identify your system as proprietary. As shown on the workow, before directly proceeding with a custom initialization of the DSP, you are required to create a valid custom model for your product in which the presets – previously created for the Powersoft model with ArmoníaPlus™ – will be included.

This process of initialization will allow the DSP to take care of the processing and the level of the input signal according to the known

characteristics of the Powersoft amplier module to which the DSP is associated to.

Furthermore, this process will also identify your DSP as part of a Powersoft system, which will

permit you to discover the device when online in ArmoníaPlus™. The latter is a fundamental requirement in order to create your original processing and your proprietary DSP presets designed for your whole nished system.

Page 33

16 : 5.2. Monitor View

By clicking on the amplier module, at rst opening you enter the Monitor view of the module, designed for the end user. In fact, all accessible settings do not permit to change internal DSP processing except delay, mute state and reverse polarity. The gain fader behaves as an attenuator; the max level is provided than the gain amount set inside the DSP.

Clicking on Advanced view , is possible entering deep inside in DSP processing, of course this is permitted only for a manufacturer with a pre-registered M-Drive license, Advanced view button does not show in case of missed license. When you pass in Advanced view rst time after the initialization as Powersoft Model, no password will be requested.

Set the maximum volume of the input signal. The attenuator knob on the interface board modies the signal volume in series with the internal settings, it is possible disabling the external gain in the internal settings. In the Monitor view, input gain behaves as attenuator with a max value set than the gain value. So, end user has the possibility just to attenuate the signal.

16 : 5.4.3. Delay

The input signal can be delayed by user denable amounts via the delay processing block. Parameters can be accessed

and set both from Advanced view and Monitor view. Delay values can be entered in the time domain (us) or as physical linear distances (in mm or in inches).

16 : 5.4.2. Polarity

The input signal can be phase reversed by clicking on this button. Polarity button is available for the end user in the monitor view.

The Mute button is provided as well to mute audio playback.

16 : 5.4.4. Safe mode and Mute

Some settings may bring to system instability and critical operating condition. The Safe Mode button provides a protection against critical settings: when activated, this function will not allow the output power to exceed a set limit (about 20W set on Power Limiter).

16 : 5.4.5. Parametric equalizer

A fully parametric equalizer processing blocks are available to ne tune the system’s sound.

Each individual selected lter can however be enabled switching on the on/off switch. A list of parameter presets of commonly used equalization schemes is available under Type combo box. For each kind of equalization, you can set Frequency, Q, Gain (when available) using the sliding box. A log scale diagram of each lter’s effect is presented, the slider on lters allows

real time variations of lter parameters such as the lter’s central frequency, gain, Q.

24 | M-Drive | User guide

Page 35

16 : 5.5. Pressure Model Operating Mode

The amplier’s output signal is modied in real time as a result of the combination of the input audio signal and the feedback loop. The alteration is applied to the input stage so to minimize the difference between the desired output and that measured and reported by interpolating two the feedback loops.

16 : 5.5.1. Pressure Control (pressure feedback loop)

This loop brings the pressure level measured at the radiating sound eld, back to the input stage. This is achieved by feeding the pressure sensor measurement through a rst order low pass lter (LPF) and a linear amplier. The parameters that can be set by the user for this feedback-loop therefore are:

 The loop gain, expressed in dB and limited by the system’s stability, dening the

strength of the feedback effect;

 The LPF bandwidth, dening the top frequency of the band at which this feedback loop

is active;

 The HPF bandwidth, dening the bottom frequency of the band at which this feedback

loop is active.

It is important to set the loop gain carefully, as too high a value will bring the system to instability. This results in a loud “ship’s horn” sound which can potentially damage the system if not silenced after a short time. This can be done by lowering the feedback loop gain until the sound stops. The entire pressure feedback loop can be bypassed by entering

16 : 5.5.2. Impedance Control (current feedback loop)

This loop brings back a voltage signal proportional to the current present at the output stage to the system’s input. The signal taken from the output is rst ltered by a rst order low pass lter. Following this step, the current/voltage translation is carried out by a virtual resistor named “Re”. The importance of this series resistor relies in the difference between traditional transducers and M-Force.

M-Force has an extremely low impedance. This means that they manifest a violent, extremely high Q resonant peak which can result in an unnatural sound reproduction. By adding a virtual series resistor Re, the entire system’s resonant peak will be slightly attened and widened in a way that mimic’s a traditional speaker’s lower Q resonance. This resistor will however not affect the power transfer from input to output as this is not a “real” physical resistor subject to ohmic heating. The parameters the user can set for this feedback loop therefore are:

 The “added Re” value, dening the additional series resistor inserted to simulate a traditional

speaker behavior. This is usually a small number, which aims to return the apparent loudspeaker resistance to a traditional 2-4 Ohm value;

 The LPF bandwidth, dening the range of frequency at which this feedback loop is active.

16 : 5.6.1. Disable External Knob

By clicking on this box is possible disabling the external attenuation knob, this must be done in case of external processor like DSP-4 connected to M-Drive.

16 : 5.6.2. Current Limiter

Set a threshold limit and the attack/release time for the average (rms) output current.

16 : 5.6.3. Power Limiter

Ensures that the real part of the average output power does not exceeds the limits set by the user.

16 : 5.6.4. Current Clamp

The Current Clamp is a faster acting current limiter. Current Clamp is meant to limit spikes of current, effectively protecting the output stage and the connected loudspeaker from dangerous high peak current: this is different respect the short circuit protection that works by sensing decreasing rails values. The current threshold value does not indicate the maximum output current, but the current level at which the limiter will start sensing spikes of current. Output current level can exceed the clamp threshold considerably due to the internal limiter design.

16 : 5.6.5. Efﬁciency Protection

Set the minimum threshold limit of the measured efciency that triggers the protections on the amp module. The pressure sensor continuously measures the acoustical output power developed by the diaphragm: when the acoustical output power falls under the expected output power, the efciency of the system lower accordingly. This can be occasionally caused by a fault either in the amp module or in the transducer motor. Powersoft recommends to set the efciency protection at least to 1/3 of the value of the reference loudspeaker efciency (Ref eff. no%, see below). The value 0 (zero) switches off the efciency protection. If the pressure sensor is not used, set the efciency protection to 0 (zero).

16 : 5.6.6. Excursion Limiter

The excursion limiter keeps the loudspeaker cone displacement within a user dened range. The threshold cone excursion is set in mm. The excursion limiter works through a current loop, dynamically changing the value of a resistance proportionally to the displacement of the cone with respect to its resting position. It is important to note that this position is estimated; its accuracy depends on the precision of the connected speaker physical parameters entered in the Physical Speaker Parameters section in the advanced parameters window (see below). The Gain (ohm/cm) parameter sets the displacement/ resistance conversion factor, so as to regulate the intensity of the limiting effect. For a given cone displacement, a higher gain value yields a more severe limiting action. The release time determines the time needed for the limiter to release the cone. Please note that the maximum cone excursion set in this window only determines the cone displacement value that activates the effect of the limiter; it does not represent the maximum excursion the cone will display. The limiter’s internal design allows for a certain margin between maximum displacement threshold value and effective cone displacement, the latter being potentially higher.

16 : 5.6.7. Gate

The system is equipped with a gate output block intended to improve the overall signalto-noise ratio. The gate reduces the output gain for small signals interpreted as noise. The hold time indicates how long the gain reduction occurs after the output signal falls below the threshold. The attenuation parameter indicates the amount by which then output gain is decreased withn respect to no attenuation. Note that the system gain changes slowly and not abruptly so the effect is unnoticeable.

16 : 5.6.8. Voltage RMS Limiter

Set a threshold limit and the attack/release time for the average (rms) output voltage.

16 : 5.7. Metering

Metering are divided in two parts, one regarding M-Drive amplier and one regarding the M-Force and loudspeaker volume. Where is present, the red line indicates the threshold level in according with respective limiter.

16 : 5.7.1. M-Drive metering

Input (Vpk) – Input peak voltage measured before input gain/attenuation processing: the meter therefore represents the signal level entering the system before any processing is performed.

Output Voltage (Vpk) – Output voltage peak level. The Limit red LED underneath the meter strip lights when the measured output voltage is being clipped to the system’s maximum possible voltage level.

Output Voltage (V

) – Output voltage rms level. The Limit red LED underneath the meter strip lights when the measured
