The EUREKA Pro Recording Channel

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 necessary 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!

Vacuum Tube Mic Preamp. 12AX7 Vacuum Tube. +48V Phantom Power, 20dB Pad. This premium tube mic/line preamp features an integrated limiter for studio, live and hard disk recording applications. It features a carefully-selected 12AX7 vacuum tube with Behringer's UTC technology for exceptional warmth and lowest noise. Using the MIC100 is a great way to eliminate the "dull" sound of standard digital recorders & sound cards. Also, it perfectly complements studio-grade condenser mics. When used as a high-end DI-box, it ensures outstanding signal integrity. Features also include a phase reverse switch, +48 V phantom power, a 20 dB pad, and balanced I/O. The heart of the Tube Untragain is an extremely low-noise microphone preamp circuitry that uses discrete components and produces a highly trans-parent sound. In combination with Behringer's tube technology, the operational amplifiers 4580 and a sophisticated circuit topology, the Tube Untragain yields excellent noise and distortion properties. The innovative UTC circuitry that has been developed by our engineering team offers an abundance of sound-shaping possibilities. Absolute musicality was Behringer's major goal when we designed the Tube Untragain. The result is a device that, thanks to our tube circuitry, lends an incredible punch to percussion instruments. On the other hand, instruments that are rich in upper harmonics will receive more transparency. The sound will be warm, detailed and brilliant.

Applications

Console input extending for both Digital and Analog mixing
consoles in Studio, Live and Broadcast
Mic Pre-amps for ADAT/ Hard Disk/ Multitrack Recording
 
Innovation
If you love your compact Digital (or Analog) mixing console, but wish it had
more microphone inputs, ARX has the solution ? the 8 Pre: eight channels
of superb sounding Microphone Pre-amps in a compact 1 RU chassis.
The 8 Pre is the ideal console extender for those times when you need more
microphone inputs. Now you can put those unused line inputs to good use,
and who knows - the 8 Pre pre-amps sound so good that you?ll probably end
up using them all the time instead of the ones that came with your mixer!
Superb Audio Quality
The 8 Pre?s ultra low noise figures come from extensive use of premium
components plus care and attention to board design and layout. The result is
superb, transparent audio quality and the headroom to handle anything that a
mic can throw at it.
Gain is adjustable from 20 db through to 60 dB via a trim control on the front
panel, plus we?ve included a ?20dB Pad switch to tame the hottest condenser
mic output if required. The Clip status LED lights up 1 dB before the onset of
clipping, just to warn you you?re getting close.Phantom power is switchable in
banks of four channels: 1 through 4, 5 through 8. A Phase reverse switch is also
provided on each pre-amp channel to eliminate any close miking problems.
In short, the ARX 8 Pre is the mic Pre-amp that you?ll wish the console manufacturer
had used. It provides a unique solution to today?s multiple Mic Pre-amp requirements.

The AD2022 is Avalon's fourth generation of fully discrete, symmetrical Pure
Class A microphone preamplifiers. The dual mono AD2022 includes the original
sonic capabilities and transparency of the M2, M22 and M5 preamplifiers plus
several additional features, including selectable microphone source loading for
optimized cable/mic matching, improved high-voltage Class A regulated power
supplies, two high Z instrument inputs, variable-passive high pass filter, teflon/
silver wiring and doubled plated circuit boards for superior low level signal transfer.
 
AD2022 FEATURES
Symmetrical Pure Class A design, two channels
Microphone and hi-Z instrument inputs
Gain switched 4dB steps plus +/- 3dB fine output trim 
Selectable microphone input impedance matching 
Low noise -126dB EIN
Ultra high quality, low-ratio, balanced input transformer
Balanced, high-current Class A output to +36dB
Large illuminated analog VU meters and twin peak LED's
Regulated phantom power supply +48v 
Input polarity phase reverse 
High headroom +36dB input before overload
Input -20dB pad for high level signals
Sealed silver relays for all signal routing
External AC 150w toroidal power chassis
Fully discrete Class A regulated audio power supplies
Deep, musical sound-stage, transparent amplification

MICROPHONE INPUT
The AD2022 incorporates the most advanced high-performance microphone
transformer available. Split low-ratio primary windings are carefully combined
within a custom mu-metal core for extended smooth frequency response and
very low distortion.  Sealer silver relays are used for minimal signal invasion. 
The input signal selector, high pass filter, polarity-phase reverse, +48v power
and the 20dB input attenuator all utilize local sealed relay operation. A variable
passive high pass filter provides a minimum phase shift design while eliminating
low frequency rumble, wind noise and mechanical vibration at sub sonic frequencies.

SYMMETRICAL PURE CLASS A DESIGN
Two 100% discrete, high-voltage, symmetrical Pure Class A signal amplifiers
are utilized per channel. The first operates in a cascaded-cascode FET
configuration while the second stage amplifier is fully bipolar. The twin amplifiers
share the total available gain requirement. This shared architecture increases
the high level headroom capability, improves transient response and doubles the
internal bandwidth of the ultra-high performance pure Class A signal amplifiers.
OUTPUT and METERING
High-current DC coupled, Class A discrete amplifiers are utilized for the output
drive interface with +36dB capability into all known loads.  Two large, high-quality
analog VU meters indicate accurate signal readings while bi-color LED's offers
peak indication at 0dB and +20dB.
