1.1 Advantages of Digitally Controlled Monitor Systems
-
optimizing of frequency responses, e.g. an absolutely linear adjustment from 30 Hz – 20 kHz.
Any other desired frequency curves can be set/adjusted/stored
-
setting of phase response(s) in any combination, such as linear-phase, minimum-phase, mixed-
phase with the resulting group-delays (constant group delay, continiously decreasing, etc.)
-
attack and release times of speakers will be remarkably improved
-
more precise stereo-locating, as there is virtually no deviation in a stereo pair
-
programmed EQ settings can be recalled instantly for special needs and functions
-
a nearly unlimited number of EQ-settings can be stored and switched easily, e.g. for different
listening locations in the same room, second control-room, different operating modes (mixing /
demonstration) etc.
-
the delay-times of the speakers can be adjusted and stored for different listening distances
-
the monitor can be delayed for optimized sync with analog/digital film/video, as a delay-line in
high-quality multi-speaker setups, concerts, multi-media or surround setups
-
the slope at the crossover frequencies can be adjusted up to 96 dB per octave, which can be
said is close to ideal (but never possible with analog designs). In this case the overlapping
frequencies reproduced from both drivers in the x-over area is only a few Hz wide, which has the
following advantages:
1. every driver can be used in it’s perfect frequency-response range
2. in the area of the crossover frequency we can avoid phase-cancellations to a large extent
3. it is possible to select a perfect horn for every driver with it’s own directivity (individual
depth of the horns can be adjusted by the system).
ð
The directivity can be designed to be almost perfect for the horizontal
and vertical level!
-
problems caused by resonances and reflections in control rooms can be minimized and
compensated to a high degree by adjusting the response of the speaker-system in the room.
This will be made in a separate EQ and measuring session in the control-room
-
for protection of the drivers fast and efficient limiters are provided which take care of the short-
term max-level and the peak-power capacity of the driver, so in case of a possible overload the
limiters will redurce the levels (feed forward limiter) without producing any distortions, as it is the
case in analog limiters.
-
Digital and analog audio input connectors
-
Infrared remote-control for all parameters (can be selected individually without any PC)
