MEQ-2000 24/96 MULTIMODE EQUALIZER,
also called DSP blue, is the first member
of the new digital audio 19" processor family, the
DSP-2000. It is a extremaly versatile digital equalizer.
The MEQ-2000 delivers warm analog sound and outstanding
features thanks to the high-quality converters, the constant
internal sampling rate of 96 kHz, and the power of absolutely
precise low-noise digital processing functions. The 31-band
graphic equalizer and 8-band parametric equalizer are
supported by 6-band notch, low-cut, and high-cut filters.
For sound finishing in mastering mode, a combined limiter/compressor
is provided, for loudspeaker protection in reinforcement
mode a reliable peak-limiter. A long separate delay in
every channel allows adjusting the sound for different
loudspeaker or spot microphone positions. The processor
offers two fully independent channels that can be coupled
for stereo use.
In connection with other members of the DSP-2000
audio processor family, the MEQ-2000 consistently
remains in the 24-bit/96kHz digital domain through the
whole audio processing path, maintaining the highest signal
fidelity. The dithering and noise shaping options at the
output of the processing chain take care of the audio
quality if tailoring down to 16-bit CD.
The MEQ-2000 incorporates high-quality
24bit/96kHz AD and DA converters as well as a sophisticated
sample rate converter. This allows digital input to accept
every sample frequency from 20 kHz to 100 kHz and digital
output to deliver every typical sample frequency used
in digital audio.
The remote control capability via MIDI or
RS-232 permits cascading the devices with other members
of the DSP-2000 family or third party equipment
and convenient controlling of the parameters over a PC
compatible computer using proprietary software.
The MEQ-2000 is an ideal universal
tool for both the mastering and reinforcement engineer.
