1.2 System Concept
-
Active 3-way studio monitor with integrated digital controller and high performance amplifiers
with power amplifiers of 400 W RMS for the woofer, 230 W RMS for midrange driver and 290 W
RMS for the tweeter
Concept of Speakers and Cabinet:
-
12“ woofer with alloy-chassis, forced air cooling voicecoil, high efficiency and long, linear excursion
-
3“ voicecoil midrange dome in sealed enclosure, with strong magnet and lowest distortion
-
1“ titanium dome tweeter with high efficiency and ultra-low distortion
-
Cabinet made of strong, resonance free HDF material. It is fitted with a moulded front-baffle with
integrated horns and ducted ports for compression-free low frequency response, and optimized
horns for midrange/tweeter, offering perfect dispersion for all three speakers by minimizing
interferences and reflections
-
Cabinet comes with multiple fittings for an individual choice of mounting adaptors
Digital Controller:
-
The integrated digital controller includes the electronic crossover, the EQ for every driver-system,
a delay of several milliseconds per chassis, all limiter functions, a master delay, flexible adjustments
for local EQ and a fully parametric 10-band EQ
-
Independent adjustments for amplitude and phase are provided for every chassis and for the
complete system by the use of digital FIR filter technology (FIR = Finite Impulse Response)
-
Unlike other internal or external digital controllers, the controller of the O 500 C is programmed
with individual filter settings for every driver system which were measured in an anechoic chamber
and set at the factory. All tolerances of the individual drivers, the power amps and the controller
itself are recorded and will be taken into the calculation for the setup / equalizing of every
specific O 500 C monitor system
-
Adjustment for positioning in the control room or studio can be made by the fully parametric EQ
with IIR filters directly in the monitor
-
Individual FIR filter settings can be made by aligning the O 500 C in it’s final position in the studio
(optional). This way the room specific modes, such as resonances, standing waves etc. can be
compensated
-
A precise limiter section will allow for perfect system management by offering a “ look ahead
signal analysis“ of the clipping mode of all power amps, the max. excursion of the drivers and
the long term temperature management and it’s peak allowances
-
The important stages in the signal path of the digital controller are calculated accurately with 48
Bit performance
-
Stacked A/D converters (gain ranging) in Delta/Sigma technology offer a wide dynamic range on
the input side, by resulting in ultra-low distortion figures at the same time
-
High performance quality D/A converters in Delta/Sigma technology in all input/output stages
-
High quality concept for the PSU and fully capsuled controller electronics
-
Variety of analog and digital audio connections
-
Ergonomic and easy operation via infrared remote-control (no PC needed)
