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.

the U5 includes many features and sonic excellence unequaled by lesser designs. The
U5 is ideal for bass guitar and acoustic instruments, electric guitars, keyboards, synthesizers
and low output pickups.
Features include state-of-the-art, high input impedance input stage for zero load effect on
sensitive pickups and keyboards, 100% discrete, Pure Class A signal amplifiers, practical
user features and rugged hardware designed to deliver true high performance audio for many
years.
DESIGNED FOR DEEP & CONTROLLED BASS
Avalon U5 DI-preamps have been in use around the world since 1995. They have found their way
into the world's leading musicians rigs and recording sessions and been featured on thousands
of the best selling (and sounding) albums and live performances.
MINIMUM SIGNAL PATH DESIGN
The U5 includes a variable gain Class A preamplifier to boost low level pickup signals and a high
level speaker input for capturing the live sound of the instruments amplifier. Six passive tone-EQ
curves are also included to enhance a variety of acoustic and electric instruments. A high-cut switch
eliminates unwanted acoustic pickup and high frequency noise, while a headphone monitor amp
has been included for personal listening. Twin DC coupled Class A output amplifiers drive both low
level microphone preamp inputs and high level +4dB inputs for direct to tape recording or processing.
The active-to-thru switch selects either the instrument input directly or sends the boosted-equalized
signal to the amplifier via the front panel jack. A ground isolation switch eliminates any possible earth
loop or AC buzz problems with complete safety.

Το ΕΡΓΑΛΕΙΟ του κάθε σολίστα για προσωπική χροιά ήχου: EWI PDI-100 PARA ACOUSTIC DI Box
ΙΔΑΝΙΚΗ ΛΥΣΗ ΓΙΑ ΟΡΓΑΝΑ ΟΠΩΣ ΚΛΑΡΙΝΟ - ΑΚΚΟΡΝΤΕΟΝ - ΛΥΡΑ - ΚΙΘΑΡΑ
EWI PDI-100 PARA ACOUSTIC DI Box
This is a medium grade professional application Para Acoustic Active DI, which will work well on instruments with passive pickups or active pickups.
The construction is reasonably rugged and the components are well suited for the application yielding results that are typically acceptable for all but the most discerning artists.
The on-board tone and volume controls give the operator a lot of choices in shaping their sound prior to sending the signal to the mix console. This allows an artist to use this device in-place of or in addition to a traditional stage amp for their instrument. This is an excellent choice for IEM bands, or bands that like to keep their stage volume low.
This item is typically used to split the instrument signal going to a stage amp so a feed can be sent also to the mix board, or be used as a stand-alone instrument pre-amp. It is equipped with a ¼” jack for input, a 1/4" jack for output to a stage amp, one XLR jack for the send to the board and a TRS jack for inserting an FX device.Since this is an active D.I. box, it needs to be powered which can be done either with Phantom Power from the mix board, or with the supplied internal 9v battery. The battery is fairly easy to change by removing one screw in the bottom of the case.
