The
Eureka is a professional recording channel strip containing
a discrete class A transformer-coupled microphone preamplifier,
compressor, and three-band parametric equalizer. The microphone
preamplifier features variable input impedance so that the
Eureka can be matched and "tuned" for all types
of microphones and recording applications. The Class A transformer-coupled
microphone preamplifier also features "SATURATE"
which adjusts the drain current on the input FET amplifier
to simulate of the effects of tape saturation and tube "warmth".
The
Eureka's ultra fast compressor has both soft and hard knee
compression as well as a separate make up gain stage and hi-pass
side chain compression to deliver hard pumping to ultra transparent
compression and everything in between. The Eureka's three-band
fully parametric EQ gives you variable Q (bandwidth) on each
band as well as an EQ pre COMP switch to put the EQ before
the Compressor in the signal path. The equalizer has overlapping
frequency selection on each band for total tonal control and
shaping.
The
Eureka is loaded with microphone, line and instrument input
so you can use it as a front end preamplifier for recording
with microphones, guitars, keyboards, synths as well as a
compressor/equalizer on a single channel during mixdown. The
Eureka also has balanced send and return jacks so that you
can insert your favorite outboard processor before the compressor/EQ
to further enhance and customize your sound.
An
optional 24 Bit/192kHz digital output card (AD192)
is available for the Eureka to further optimize sonic performance.
The Eureka's AD192 digital output card is loaded with both
SPDIF and AES/EBU outputs, word clock I/O as well as
a balanced TRS line input so that only one output card is
nessesary when using two Eureka's in stereo or dual mono situations.
The
Eureka gives you the sonic performance and control you need
in the real-world to produce professional quality audio that
you, your customers and your fans deserve!
