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.
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 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.
The system´s reliability and dynamic range are
determined by the rms and clip limiter thresholds.
Don´t vary them.
