Digital 4-channel power amplifier "Handmade in Germany".

The MiniPac 2004 DSP offers extensive functions that professional users need for many common sound

reinforcement tasks. The user interface, which has been deliberately kept simple, with a choice of 5 DSP

presets and a volume control on the front, makes the MiniPac 2004 the ideal installation power amplifier,

not just because of its compact dimensions. Audiophile presence, low weight and a freely programmable

DSP are features that mobile DJs, musicians or sound engineers need for smaller sound reinforcement

tasks. The MiniPac 2004 DSP solves a wide range of sound reinforcement tasks with flying colors.

USER MANUAL MiniPac 2004 DSP

Technical data overview

Product detailed description

The PowerPac 2004 DSP has two identical power amplifier modules. A digital signal processor with a

multitude of setting options (X-Over, Compressor, Limiter, signal routing, parametric equalizer, delay, ...)

takes care of signal processing and loudspeaker management in a deliberately simple menu. The over-

complete connection field on the back has - in addition to the loudspeaker system connections (4-pin

Speakon®) - XLR signal loop-through for the input channels. This means that the MiniPac 2004 DSP is

ideally equipped, especially in the installation area, to handle signal processing and signal routing for

simple multi-channel systems, while at the same time being simple to operate and comparatively low in

weight.

Mains connection

The device may only be connected to an electrical installation that complies with the VDE regulations

DIN VDE 0100. The electrical installation must be equipped with a residual current circuit breaker (RCD)

with> 30mA rated residual current.

The devicve is supplied with dangerous mains voltage (>50 Volt AC). Therefore never intervene on the

device on yourself! There is a risk of electric shock! Connection cables has to be protected against

crushing, tensile load and bending. Cables and wires are to be laid or secured in such a way that no

one can trip over it or may fall.

Damaged Mains-Power cables must not be used and should immediately be rendered unusable against

further use, e.g. cut off both plugs.

The device is powered by a Neutrik Powercon® connector. In contrast to a plug-in device (such as a

safety plug), the Powercon® plug-in connection must not be plugged in or disconnected under load and

also not under voltage! The consequences are stuck or burned-out contacts and the resulting loose

contacts lead to failures or even destruction of the electronics or even the risk of fire. You should

therefore only switch the device ON or OFF using the 2-pole power switch on the front panel of the unit.

The mains plug may only be connected to an earthed safety socket with the associated mains

connection cable. If extension cables are used, it must be ensured that the wire cross-section is

dimensioned and approved for the power supply required for the device! Make sure that the

mains voltage of the socket corresponds to the permissible voltage values in this manual.

The power supply of the amplifier is equipped with an intelligent mains voltage detection. It allows

worldwide operation on all power grids. After switching on, the electronics check the mains voltage

and switches the power pack to the correct voltage range 115VAC or 230VAC.

If a three-phase current generator is used at events on which the device is to be operated, the

correct mains voltage must be checked before connecting the amplifier! In the event of faulty

three-phase power supplies without a neutral conductor, a so-called neutral point shift can result

in up to 400Volt being applied to the protective contact sockets. This overvoltage leads to the

destruction of the electronics in the amplifier.

The device has a PowerCon®-Out (6) over the existing Powercon®-IN (5). This is provided for the option

of connecting another device through a short interlink PowerCon®-cable eg. when built in in a rack with

other amplifiers or other devices. Please make sure that the overall power consumption of all connected

devices does not exceed the maximum power of 16 Ampere, or the maximum allowed power limited by

the upstream line circuit breaker.

Please refer to the technical data for detailed information regarding power consumption of the MiniPac

2004 DSP.

Best option is to connect the MiniPac 2004 DSP to its own circuit with a 16A fuse (characteristic curve C).

Please refer to the technical data for the power consumption in the different operating states.

The device corresponds to protection class 1.

In the event of a thunderstorm or danger, pull the power plug out of the socket immediately.

To avoid ground loops, we recommend using symmetrical signal routing and the power distribution in

the so-called star point earthing, which means, all ground connections meet at one single point.

Never interrupt the contact to the protective conductor (e.g. by cutting off the protective conductor,

disconnecting the connection to the protective conductor through insulation, etc.), because in the

event of a defect this increases the risk of a electric shock over the metal housing.

Power generator operation

If the amplifier is operated on a power generator, this is done at your own risk!

Extensive precautionary measures must be taken before connecting and operating your device on a

power generator:

•Use only high-quality, generously dimensioned power generators

•perPowerPacat least3kVA rated power

•If possible, switch on an under / overvoltage shutdown, this should be at U min.200VAC

undervoltage and U max. 250VAC overvoltage!

•Always load three-phase generators equally to avoid unbalanced loads, e.g. PowerPac 1 on L1,

PowerPac 2 on L2, PowerPac 3 on L3

•Load the generator permanently with a stable base load in order to absorb voltage fluctuations.

e.g. 1000W halogen lamp, electric heater etc.

XLR connection

XLR inputs can be connected both balanced and unbalanced. Symmetrical cables are to be preferred, as

they provide better protection against external interferences on long cable routes. Depending on the

operating mode or preset of the power amplifier, only certain XLR inputs are used. The

operating mode of the device can be set using the preset button on the front for the first 5

presets (1-5) and via the software for the remaining 75 presets (6-80)by loading the respective

preset. The inputs Input A and Input B can be controlled with signals up to +24dBu. The user has the

option of further processing the fed-in XLR signals via the XLR Out socket, e.g. in another PowerPac.

Pay attention to the following assignment of the XLR connection.

Speaker connection

Before loudspeakers are connected to the Speakon® outputs of the MiniPac 2004 DSP, reduce the

output level of the upstream components to the lowest possible value (e.g. fader down or left stop; )

in order to reduce/avoid any unwanted and possibly damaging noises in the connected loudspeakers.

Make absolutely sure that any upstream crossover or any upstream limiter is set correctly. Due to the

high output power of the MiniPac 2004 DSP, non complete or incorrect settings can damage the

connected loudspeakers due to overload!

The upper Speakon® outputs on the rear panel (page 8, lower picture, number 4)

are intended for the system cabling of PL audio systems. With the system cabling –

assuming the correct preset is selected - only a single 4-pin Speakon® cable is laid

between the power amplifier and a sub / top combination to each side of the system.

Pins 1 + / 1- are wired for the tops, pins 2 + / 2- for the bass. The lower Speakon® out-

puts are available so that third-party systems can also be conveniently wired using a

four-pole Speakon® cable. These are - also assuming the selection of the appropriate

preset - wired mirror-inverted to the upper connections (pins 1 + / 1- bass and 2 + / 2 tops).

When connecting the system using prefabricated connection panels, patchbays or adapter plugs /

adapters, make sure that the signals are correctly assigned to the correct components! This is of top

importance when using the MiniPac 2004 DSP for wiring bi-amp systems. Special care must be taken,

as possible incorrect cabling can quickly lead to the destruction of the mid-range or high-frequency

driver!

Important notice: Do never load the output channels with less than 4Ω!

USER MANUAL MiniPac 2004 DSP

Speakon® connector

Backside

2.6 Speaker connection

Before loudspeakers are connected to the Speakon® outputs of the MiniPac 2004 DSP the corresponding

preset must be loaded on the signal processor! Only with the correct presets, specially developed for the

loudspeakers by PL-audio reach their maximum performance, the best possible sound and the necessary

operational reliability.

By loading the wrong the speakers my sound bad and / or may be damaged through overload!

If you want to operate loudspeakers from other manufacturers on the MiniPac 2004 DSP, there are

enough free preset memory spaces available on the device! As a starting point we recommend the "01.

Sub + Top Standard“ preset to be loaded and sent to your speakers plus conducting the absolutely

necessary adjustments (gain, HPF, LPF, EQ, limiter, etc.).

Bi-Amp connection

2-way actively separated loudspeakers do not have a built-in passive crossover. On such loudspeakers,

each path has its own amplifier channel. An amplifier channel operates the midrange speaker (s) (e.g.

channel 2 - mid) while another amplifier channel drives the Tweeter(s) (e.g. channel 3 - high). This Bi-

Amp system uses a 4-pole Speakon® cable (page 8, item 3, rear panel) between Speakon® connector

and loudspeaker, where pins 1 + / 1- transmit the processed and amplified signal of channel 2 and 4,

while the processed and amplified signal of channel 1 and 3 is transmitted via pins 2 + / 2-. When

wiring bi-amp systems it must be worked out with particular care, as incorrect cabling quickly leads

to possible destruction of the high-frequency driver!

SELECTING THE CORRECT PRESET IS ABSOLUTELY CRUICAL FOR CORRECT OPERATION, CORRECT

CONFIGURED OUTPUT AND MAXIMUM SOUND QUALITY!!!

PL-audio Bi-Amp presets are usually locked in the signal processor with password protection in order to

prevent unintentional changing of the parameters. If you make changes here do this very carefully, with

caution and expertise! The signal processor allows very deep and detailed, but also serious changes in

the transmission parameters of the speaker system! To change the bi-amp presets, log in with the

password:"Admin1" in the administrator user level of the signal processor. Now you have full access to

change all necessary parameters.

This is easy and convenient with the PL-audio DSP-CONTROL software on the PC.

Network communication

Page8(MiniPac-front panel, item 4) Network / Ethernet Interface

With the network interface you can integrate the DSP controller into a local network, to control and

operate it remotely through longer distances with the PL-audio DSP-CONTROL software. If you connect a

wireless router to the network port, you can take advantage of wireless remote control with a W-LAN-

enabled device!

The network port also offers the option of connecting the DSP directly via a commercially available

network cable (up to 100m in length, CAT5e or higher) directly to a computer.

If the DSP is not automatically registered in the IP universe of the computer through the direct connection

PC → DSP , an intermediate router is required, which has DHCP server functionality that automatically

assigns an IP address that can be located by the computer.

The network port is designed as 10-Mbits Ethernet. RJ-45 connector standard.

Installation

Please note that if the device is cold and transported into a warm environment, condensation will form

inside the device. To avoid damage and malfunctions due to condensation / moisture, let the device

acclimatise first.

To avoid unpleasant and possibly damaging noises in the loudspeakers, always switch the individual

components on in the direction of the signal path. So first the player, then the mixer and only at the end

the power amplifiers. When switching off, just proceed in reverse order.

After switching on the device, a self-test and initialization are carried out. The fan runs up once for

approx. 4 seconds. During the start-up process, the loudspeaker outputs of the power amplifier are

muted and are activated automatically as soon as the power amplifier is ready for operation. This

protective circuit prevents unpleasant "cracking" noises in the loudspeakers.

The amplifier is ready for operation approx. 10 seconds after switching on.

Before switching on the power amplifier for the first time, it is not possible to check which volume or

which speaker preset is set! Therefore, please always turn the volume level of your signal source (mixer)

to a minimum.

ATTENTION: The power amplifier has a gain control on the front (page 8, upper figure, number 6)! To be

on the safe side, turn it all the way to the left BEFORE switching on. Alternatively, you can also unplug the

XLR signal cable or the Speakon® speaker cable.

When you have made all connections, switch on the amplifier, check whether the correct preset is loaded

and in-crease volume gently until you hear the signals from your speaker system. If you do not hear an

output signal on the connected loudspeakers, check the cabling again before turning the level up any

further. In any case, avoid the limiter LED lighting up continuously (page 8, upper figure, item 7). This not

only leads to a loss of sound, but can also damage connected speakers!

USER MANUAL MiniPac 2004 DSP

Limiter settings

If you program your own presets in addition to the factory presets, we strongly recommend that you

calculate and set the limiter settings for the respective channels precisely in order to protect your

connected speakers from overload! The limiters are already set at the factory presets.

Network connection

If you want to remotely monitor the DSP via W-LAN, for example, connect the network connection

socket (RJ 45) on the front to a suitable router or directly to your computer. You can then easily make

the settings on the computer and monitor the power amplifier remotely.

Limiter settings

If you should program your own presets in addition to the factory presets, we strongly recommend that

you calculate and set the limiter settings for the respective channels precisely in order to protect your

connected speakers from overload! The limiters are already preset in the factory presets.

LowCut-button (Page 8, uooer picture, item 5)

The LowCut button on the front can be used to switch a LowCut filter that can be programmed via the

software into the input path. To program, go to the "IN 1" menu of the software. At the bottom you will

find a button "HPF" with the option of entering the desired crossover frequency and the option of

selecting the filter slope via the drop-down menu. Here you can set or select both the frequency and the

slope. If you leave this input window empty, the LowCut switch on the front has no effect on the signal

reproduction.

If the "HPF" filter is activated in the software,

the associated red LowCut indicator LED also

lights up on the PowerPac 2004 DSP. After

saving the settings in the desired preset this

high-pass filter can can be switched on or off

using the LowCut button on the front of the

MiniPac 2004DSP.

The MiniPac 2004 DSP offers the user numerous possibilities:

The amplifier has 2 output channels per amplifier block, 2 x 500W 4Ω. This power is made available at

the Speakon sockets®, which are located one above the other for each power amplifier module. The

upper sockets are connected as system cabling sockets with Ch 1 to 1 + / 1-, Ch 2 to 2 + / 2- and Ch 3 to 1

+ / 1-, Ch 4 to 2 + / 2-, while the lower sockets are used as bi-amping sockets with Ch 1 on 2 + / 2-, Ch 2

on 1 + / 1 + and Ch 3 on 2 + / 2-, Ch 4 with 1 + / 1-.

Several configurations can be operated per power amplifier block (see examples below):

•Up to 2 subwoofers á 8 ohms and 2 tops with built-in crossover á 8 ohms.

•Up to two monitors with built-in crossover of 8 ohms plus, for example, two side or front fills of 8

ohms with built-in crossover

•many other combinations (e.g. multi-room or multi-speaker applications) in which the sum of the

nominal apparent resistance per power amplifier channel does not fall below 4 ohms.

If you connect an 8Ω loudspeaker to channel 1 or 2 of the MiniPac 2004 DSP, it receives 250W

into 8Ω. If an additional loudspeaker á 8Ω is added to channel 1 or 2, the impedance is reduced to

4Ω.The 500W (which are available at 4Ω) are now divided between both speakers, and each

speaker receives 250W at 8Ω. Calculation example: (250W 8Ω + 250W 8Ω = 500W 4Ω).

The same principle mentioned above applies to channels 3 + 4 of the MiniPac 2004 DSP.

The ideal use of the MiniPac 2004 DSP is as a system amplifier for smaller system applications - with

subwoofer and tops or - thanks to the extensive setting options of the built-in digital signal processor -

various multi-room or multi-speaker applications in the installation area. Last but not least, the MiniPac

2004 DSP can also drive smaller subwoofers with at least 8 ohms in bridge mode with 1kW.

The following examples give a brief overview of the various configuration options.

In the example given above, the MiniPac 2004 DSP takes on the supply of up to 2 subwoofers á 8Ohm

(500W) and up to two tops with integrated crossover á 8Ohm (500W) per power amplifier block. The

specific frequency range assignment for the subwoofer (Low Pass / HiPass) or the tops (HiPass) is made in

the DSP. With PL-audio, both components, subwoofer and tops ,can be connected to the upper Speakon

sockets® (CH 1 / CH 2 and CH 3 / CH 4) using a 4-pin Speakon cable®, whereby channel 2 + / 2- transmits

the bass signal and channel 1 + / 1- transmits the signal to the tops (mid & high). The signal assignment to

the midrange and tweeter in the tops is done by a crossover built into the tops. In the example above,

the XLR Thru could control the front or side fill via an external amplifier (e.g. MiniPac 2004 DSP). In this

case, please note that the signal coming from the input signal is looped through unchanged.

In this example, the inputs A / B of the MiniPac 2004 DSP receive the Hi- and Low-Pass processed

subwoofer signals from an external power amplifier with DSP (here the PL-audio PowerPac 4004 DSP) or

a crossover. In this example, the MiniPac 2004 DSP drives an 8-ohm subwoofer in BTL mode (Bridge Tied

Load) with a maximum output of 1.000 watts at 8 ohms per power amplifier module using a specially

wired Speakon cable® (1+ to subwoofer + and 2+ to subwoofer -).

In the example outlined here, the MiniPac 2004 DSP supplies up to 2 subwoofer á 8Ohm (500W) and up

to four tops with an integrated crossover á 16Ohm (500W) per power amplifier block. Both components,

subwoofers and tops, can be connected to the upper Speakon sockets® using a 4-pin Speakon cable®,

whereby channel 2 + / 2- transmits the bass signal and channel 1 + / 1- transmits the signal to the tops

(mid & high). The signal assignment to the midrange and tweeter in the tops is done by a crossover built

into the respective tops.

In the example above, the loudspeaker groups are divided into different zones. For this example, it is very

likely that you will not use the stereo sum of the mixer, but rather deliver an individual matrix mix to the

two inputs A and B. The XLR-Thru is fed to 4 passive loudspeakers (e.g. TS 41) via an external four-

channel amplifier (e.g. MiniPac 2004 DSP) using an XLR cable. In this case, please note that an individual

signal or level adjustment on the output side is not possible for the XLR Thru, as the signal is looped

through directly and unchanged. The volume for the 4 TS41s in Zone 3 listed in the example - driven by a

MiniPac 2004 DSP - could be achieved here, for example, using the frontside located gain control of the

MiniPac 2004 DSP in Zone 3.

Loading of presets on the device

Load preset:

–Press the preset selection button on the front (page 8, upper figure, number 3) until you have reach-

ed the desired memory location with the control LED. At memory location 5 the selection jumps back

to 1 after pressing it again.

–Allow the DSP a few seconds to load the preset properly before sending a signal to the inputs.

The preset is now in the signal processor and the parameters are executed.

Tip: When configuring for installation purposes, we recommend that you save the installation configuration

identically in memory locations 1-5, so that if you accidentally press the preset selection button, undesired

configurations and any associated undesired sound parameters do not occur.

Mixer

Using the built-in DSP, the signal curve and the signal level can be set individually for each input and output

channel via the mixer. Inputs A & B and outputs 1 & 2 or 3 & 4 can be linked in pairs using the link buttons

below the respective faders. When the function is switched on, the color of the button changes from gray to

blue. Any settings can only be made in input A and outputs 1 and 3 for linked inputs and outputs.

The values are adopted directly for

input B and outputs 2 and 4.

For the respective outputs, the mixer selects which input signal is used at which level. When using the output

for a subwoofer, we recommend using the input signal from both inputs. For stereo localization, the input

channel that is signal-relevant for the respective output is used (e.g. input A for left →in the mixer input A

to the desired value, while input B is set to “mute” using the fader).

USER MANUAL PowerPac 2004 DSP

Up to 80 presets can be stored in the flash memory of the DSP controller. You can load the first 5 presets

from a list with a maximum of 80 presets stored in the memory using the preset selection button on the

front panel (page 8, upper picture, number 3). The presets that cannot be called up using the button on

the front of the MiniPac 2004 DSP can be called up using the software and, if necessary, also reconfigured

to the first five memory locations.Presets can be labeled with up to 16 characters. Please do not use any

special characters when naming.

lending, the DSP can be locked with password protection. (Access Level: Locked)

In the PL- Audio DSP-Control software click in the control window on the menu item:

Hardware → Lock Unit → Confirm the upcoming advise with OK.

The DSP has 3 user levels, which can be called up by entering the corresponding password.

1: Locked –Level

2: User –Level

3: Admin –Level

DSP Locked

Password: PLAudio1

Password: Ad_min

If you have blocked DSP access via the display or the control window on the PC, all setting options in the

controller cannot be configured.

To regain access, enter the passwords for either the user or admin level via the display or the control

window on the PC and activate the user rights. All setting options can now be called up again.

The input field for the password in the computer software can be found in the control window under

the menu item

Hardware → Enter Passwort→ now the input window opens in the software.

In order to always have the latest firmware on the signal processor, you should carry out a firmware

update regularly. The update can only be carried out with a PC. Please always download the latest DSP

control software from the PL-audio homepage and install it on your computer.

This application contains 2x the firmware uploader.

Once in the network manager for a complete new installation and in the control window under the

menu item Hardware → Firmware Update

Important: Please note that with a firmware update all presets saved on the flash memory of the DSP

will be lost. It is therefore essential to save these presets on your computer BEFORE an update!

For the firmware update you should preferably use the network interface on the DSP, since the bootloader

of the network chip is updated at the same time.
