The Great Discovery
The name “Eureka” derives from a Greek
word meaning “I have found it!” It was made famous by the ancient Greek
scholar Archimedes, indicating exultation at a great discovery. Try
the sweet-sounding, super-versatile Eureka preamp and signal processor,
and you’ll discover the answer to a variety of sonic needs.
One of
our best-selling products, the Eureka is equally at home in the studio
or at the gig. With separate mic, line, and instrument inputs, you can
employ it on almost any sound source.
Sweetening starts with our
high-headroom Class A solid-state mic preamplifier, with variable input
impedance to match any type of microphone. A Saturate control
simulates the effects of tape saturation and tube warmth so you can go
from crystal-clear to warm and rich.
The Eureka’s versatility
stems in part from its malleable signal flow. The EQ can be pre- or
post-compressor, and you can bypass each independently. Balanced send
and return jacks enable you to insert your favorite outboard processor
before the compressor and EQ. The backlit VU meter can display gain
reduction or output gain.
The fast, fully variable compressor
includes an internal sidechain with variable (10 Hz to 10 kHz)
high-pass filter, so it can achieve anything from hard pumping to
transparent compression. Its three-band, fully parametric EQ has
overlapping frequency selection on each band.
With both XLR and
¼” line outputs, you can connect the Eureka to almost any recording
interface, amp, or P.A. system. You can even transfer the signal
digitally using the optional AD192 digital-output card, which provides
word-clock I/O and two 24-bit, 192 kHz, stereo A/D converters that
simultaneously feed the S/PDIF and AES/EBU digital outputs. A ¼” line
input lets you use the card to provide digital output for a second
Eureka.
Try the Eureka. Like the great Archimedes, you’ll be shouting, “I have found the solution!”
