Instruction manual
The newly developed professional active DSP LINE ARRAYS , serie: Digivoice -110.8 DSP2 (8-channels DSP) and serie:
Digivoice-220.16 DSP2 (16-channels DSP), have been developed especially for sound transmission in acoustic difficult
areas with long reverberation times like such as churches, conference rooms, museums, cathedrals, conference centers
and halls, but also as the perfect „sound producer“ for multimedia applications.
The active DigiVoice audio systemes consist of software-controlled speakers, each of the 8 resp.16 DSP channels has
an own Class-D final stage which are regulated with different acoustic characteristics to fulfil the acoustic requirements
of the particular location.
The DSP supported speaker systems allow a precise directive sound and high-precision directivity by a high-quality
mathematical calculation of the optimal parameters by the DSP (audio signal processor).
Steady volume in the ranges @ 95 dB „NEAR FIELD“ and „WIDE FIELD“ and an excellent speech intelligibility in the
complete sound range are only some advantages of the DigiVoice serie.
Most important features are the continuous electronical controllability of sound outlet angle and inclination angle
in vertical direction in real time, without mechanical direction of the speaker systems (incline).
The Digivoice systems provide specific incline adju / -45 degrees) and the vertical sound angle (6 degrees
to 14 degrees), parameterization is done by the system automatically by the digital DSP control.
Beyond that the integrated DSP audio system offers a whole lot of audio processing functions:
MAIN CONTROL (basic settings)
- Volume control
/ volume control
(-20 dB to +6 dB)
- Delay adjustment (0 to 500 ms)
- Signal limiter with threshold (-40 dB to +6 dB) with mode: SLOW/NORMAL/FAST, adjustment
- Noise gate with LEVEL/ATTACK/RELEASE, adjustment and BYPASS.
DEVICE SETTINGS
- Automatic „SCANNING“ of the IP addresses of all networked DigiVoice speakers.
- Besides that automatic allocation of the COM PORTs with port time out and COM-port display.
BEAM CONTROL (User settings)
- Column elevation / m
ounting height
: (distance of the floor area) with setting parameters 1.5 m to 3 m height.
- Focus distance
/ beam range
: (directivity length while maintaining the sound pressure) according to model up to 25 meters.
- Focus elevation / b
eam height
: height setting for the acoustic lense in the area of 0.5 to 3 meters.
- Opening angle: width setting for the acoustic lense in the aera of 6 to 14 degrees.
PEQ (parametrical equalizer)
- Selection of up to 10 PEQ elements.
-
Frequency selection of 20 Hz to 20 kHz.
-
Range of effects Q-factor of 0.05 to 3 OCT.
-
Setting of amplification or deadening of the selected frequency of -20 dB to +12 dB.
