Safety Precautions

Keep these instructions. Read them carefully. Heed all warnings. Follow all instructions.

The exclamation point within an equilateral triangle is intended to alert the user of important operating and maintenance instructions in the literature accompanying the appliance.

The lightning flash with arrowhead symbol within an equilateral triangle is intended to alert the user to the presence of uninsulated “dangerous voltage” within the product´s enclosure that may be of sufficient magnitude to constitute a risk of electric shock to persons.

Do not use this apparatus near water.

Do not expose this devices to rain or moisture.

Do not place any objects containing liquids such a bottles or glasses on top of the unit.

Clean only with a dry cloth.

Class I device.

A50racks require Class 2 ouput wiring.

Do not install near any heat sources such as radiators, heat registers, stoves or other apparatus that produce heat.

A50rack

Do not block ventilation openings. Install in accordance with the manufacturer´s instructions.

Take into account that the nominal AC voltage is the value shown in the equipment +-10% (according to IEC60065:2001).

Protect the power cord from being walked on or pinched, particularly at plugs, convenience receptacles and the point where they exit from the apparatus.

Refer all servicing to qualified service personnel. Servicing is required when the apparatus has been damaged in any way, such as power supply cord or plug is damaged, liquid has been spilled or objects have fallen into the apparatus, the apparatus has been exposed to rain or moisture, does not operate normally or has been dropped.

TO PREVENT ELECTRIC SHOCK, DO NOT REMOVE TOP OR BOTTOM COVERS. NO USER SERVICEABLE PARTS INSIDE. REFER TO SERVICING TO QUALIFIED SERVICE PERSONNEL.

WARNING: TO REDUCE THE RISK OF FIRE OR ELECTRONIC SHOCK DO NOT EXPOSE THIS APPARATUS TO RAIN OR MOISTURE.

THE MAINS PLUG OF THE POWER SUPPLY CORD SHALL RAMAIN READLY ACCESSIBLE.

TO COMPLETELY DISCONNECT THIS EQUIPMENT FROM THE AC MAINS, DISCONNECT THE POWER SUPPLY CORD PLUG FROM THE AC RECEPTACLE.

In order to avoid noise or hum, and protect the input/output stage of the systems electronics from serious damage, proper grounding connections of all the components of the system are required. Connect the components making sure that AC line polarity is maintained, and that all grounds are connected to a common grounding point using the same gauge cable as the neutral and line cables.

D.A.S. recommends that before powering up any D.A.S. system, test the mains making sure that the voltage potential difference between the neutral and ground does not exceed 5 VAC.

Introduction

The A50rack is a rugged touring rack that includes power amplifiers, processors, power distro, input patch panel and output patch panel for the aero 50 line array systems.

There are two different options for the A50rack. Option1 (A50rack_1) is assembled with 3 x DAS Audio D-100 four channel amps and a DAS Audio DSP-2060A. The D-100 amplifier is a 4 channel class D switching power supply amplifier of 2800W per channel.

In Rack Option 2 (A50rack_2) comprised by 6 x PowerSoft K-6DSP AESOP amplifiers. The K-6 DSP includes its own DSP and is a class D switching power supply 2 channel amp. Power per channel is 3600W@2ohm.

Input patch panels have 2 or 3 (depending on the option) input connectors to create separated zones in the array.

The aero 50 is a three way large format line array system to be used for live sound applications.

Two 15” loudspeakers with neodymium magnet assemblies reproduce the Low Frequency range. Four 8” loudspeakers with neodymium magnet assemblies reproduce the Mid Frequency range. Two 3” coil neodymium compression drivers with

1.5” exit reproduce the High Frequency range.

The system has been designed to have a nominal Horizontal coverage of 90º. In the coupling plane (vertical) the coverage depends on the frequency and the splay angles between cabinets, as it is a true line array system. To ensure the performance of the system and the uniformity of the horizontal and vertical dispersion X-over points must not be changed.

A family of locked presets is provided for different DSP platforms; DAS DSP-2060A and 4080 and Lake LM-26 / PLM / K-6 amplifiers.

DAS Audio offers racks with amplifiers and processors. The processors in the racks adjust the levels between the ways (LF, MF, HF), the crossover points, delays and Eqs. These settings must remain without any variation to ensure the optimal acoustical performance of the system. (this is the main reason why they are locked). Besides basic parametres, inside the processors clip and rms limiters are set up.

In rack option 1 the output panel of the rack is always composed of three Speakon NL 8 connectors which will power up to two aero 50 each one working at 4ohm and up to 4 aero 50 (2ohm load) in the powersoft case, in rack option 2.

The presets

The family of presets available for the three main different platforms (DAS DSP-2060A/4080, PowerSoft K-6, Lake Lm26 / PLM) is based on a flat frequency response of a single aero 50 cabinet. For updates check the DAS Audio website (aero 50 related downloads).

Type B: to be used at the FOH DSP-4080 processor. The preset will compensate the array effect and the number of cabinets used. These presets will be named as follows: A50Vx.y 8U A50Vx.y 10U A50Vx.y 12U

For instance: A50V52 16U

www.dasaudio.com/en/p/aero-50-2/

For DAS DSP-2060A and 4080 the presets are available in AudioCore .xaa format.

http://www.dasaudio.com/DOCUMENTOS_D/SOFT WARE/AUDIOCORE_V871.ZIP

For the Powersoft K-6 DSP amplifiers presets are available in Armonia format.

http://www.powersoftaudio.com/en/support/armonia-supportforum.html

For the Lake LM26 /PLM amplifiers, presets are available in .csm lake format.

http://labgruppen.com/support/software_firmware/

Different High Pass X-overs for the LF are provided; (a) 45Hz to be used as a full range system without subs, and (b) with cut at 80Hz to be used with LX-218C (or CA) subs.

preset version

Number of Units

Besides the High Pass X-overs presets are available for long (LT), mid (MT)and short throw (ST) zones in the array. To achieve a uniform sound pressure level across the distance and optimal acoustical performance a line array system has to be managed in groups of cabinets with different presets. For instance the four bottom cabinets should have to be treated as the downfill or short throw of the system.

There will be two different types of presets:

Type A: presets to be used in the rack processors to define all the settings in one cabinet. Presets for all these platforms: DSP-2060A, LM26 and K6DSP. Presets will be named as follows:

A50Vx.y LT A50Vx.y MT A50Vx.y ST

For instance: A50V5.4 ST

- To recall a memory or a preset using the front panel: press menu -->enter--> global memory-->enter-->recall a memory->enter-->Crossover-->enter and select the desired one.

All the previous listed presets or memories on the DSP-2060A are X-over type.

- When the DSP is connected to a computer using AudioCore software, to recall a memory (once the communication between DSP and computer has been stablished) just do right click on the DSP main window:

Mid Throw

Long Throw

Short Throw

- When the DSP is connected to the computer but is not including factory presets just connect the unit to the computer and open the desired audioCore file. For example open A50V55 LT+MT.xaa Next step, click On Line and send Settings to the unit. Once the unit (DSP) has the preset loaded the user can store it via software or via front panel.

Example: a system with 12 aero 50 per side with 3 different signal groups would be configured as follows:

LT LT LT LT MT MT MT MT ST ST ST ST
