| Content | In this era of digital audio, more and more musicians, engineers and producers are longing for
the warm, full-bodied sound produced by vacuum tubes. Say hello to the all-new TP-2. In one
rugged and compact unit, the TP-2 combines a dual channel tube preamp, optical compression
and digital outputs ? a total solution for your demanding audio applications.
Two for one!
The TP-2 offers two completely independent preamps, with individual realtime controls. Each channel
is driven by its own 12AX7 tube. A ?Stereo? switch on the front panel allows both preamps to work in
tandem when processing a stereo source.
Full-featured mic preamps
Using a specially tuned version of the Valve Force technology so widely acclaimed in the Electribe X
series and the TRITON Extreme, the new TP-2 tube-driven preamp imparts a robust warmth and a rich
musical character that is ideal for your critical and challenging acoustic sources. Each preamp channel
accepts either XLR or 1/4" TRS inputs, and switchable phantom power is provided. Equipped with a Hi-Z
switch, 26dB pad button and a variable trim knob, the TP-2 assures the optimal gain setting for any source,
from a premium microphone to a direct bass or guitar signal. A pair of faders controls the output level,
and a low-cut switch and a phase reverse button offer even more flexibility.
Transparent optical compression
By using state-of-the-art optical compression, the TP-2 is able to respond quickly, breathing life and luster
into your sound. In addition to enhanced response times, optical compression provides a wide range of
dynamic control ? without coloring the source material in adverse ways. Compression sensitivity knobs on
the front panel are teamed with Fast/Slow release time buttons and audiophile analog VU meters for intuitive
realtime control.
Best of both worlds
While the TP-2 works hard in the analog domain to achieve warm, smooth and musical results, its digital
characteristics are no less stellar. Analog-to-digital conversion is 24-bit, using 64-times oversampling for
error-free reproduction. Sampling rates of 44.1, 48 and 96 kHz are offered, and the digital output is provided
in both S/P DIF optical and coaxial formats. Analog outputs are also provided.
Use it anywhere
While the TP-2 is obviously well suited to enrich your hardware or software based digital recordings, it is
perfect for a variety of applications. Live, the TP-2 can be used to add warmth to any vocal mic or acoustic
instrument. As a mastering tool, the TP-2 provides superior dynamic control. You can even use it as a preamp
when preparing audio samples for your keyboard or computer.
XD series plug-in version
For those of you who are already using Korg?s D32XD or D16XD Digital Recording Studios, the full functionality
and feature set of the TP-2 is available as an optional enhancement for these Xtended Definition recorders in the
TPB-2. The TPB-2 mounts directly into the option bay on the D16XD or D32XD front panel.

Having had great success with the PRE-73 preamp, we have received many requests for a version for the 500 eries rack format. We are therefore happy to present the PRE-573, expected to start shipping in late September.
The PRE-573 is a one width module that has the sound and the features that made the PRE-73 so successful and a few additional ones.
The circuit still uses the preamp and output section from the classic 1073-module, adapted to work in the api rack format. It has a total gain range from -15 to +80 dB. The 10 - 70 dB range is handled by a turn switch and there is a separate toggle switch to select an additional 5 or 10 dB gain. The input can be configured to accept line level signals by another switch, the gain is then lowered by about 25 dB and the input impedance increased to about 15 kohm.
The input impedance of the mic input mode can be switched between 1200 and 300 ohm. Phantom power and phase reverse is also selectable by front panel switches.
An added feature, using the same circuit as in the PRE-73 DLX, is the active DI-input with a high input impedance of about 1,5 Mohm. The output signal from the active DI circuit passes through the input transformer for some extra character.
The DI-input is very flexible since it can be changed to a purely passive one by a front panel switch. The DI input is then exactly the same as in the PRE-73 Mk2 where the signal is feed directly into the second gain stage, bypassing the transformer and with an input impedance of about 100 kohm.
These two DI-options makes it possible to get different tones from electric instruments and the passive DI input mode is more suited for injecting active units like sound modules.
A new feature is the switchable AIR mode that adds a small boost above 10 kHz that peaks at 2 dB at about 35 kHz.
A simple but effective signal and overload indicator is offered by a single LED that starts glowing red at about +4 dBu and then increases its intensity up to the maximum output level.
The PRE-573 has a dedicated insert connector at the back allowing it to interface with other GAP 500 modules. The insert can be activated by removing a jumper connector at the back of the module.
The second Golden Age Project module for the api 500 rack will be the EQ-573, expected to ship in November 2012. The EQ-573 consists of the inductor based high pass filter section and the 3-band eq section from the classic 1073 module with some added frequencies. These two modules together will offer a fully fledged 1073-module in a compact format at a very low cost.
There is a second jumper at the back of the module that selects 600 ohm termination on the output. The standard mode is termination on, since it gives the flattest response when the PRE-573 is used with modern line inputs that typically has an input impedance of 10 kohm or more. The user can chose to remove the jumper and deactivate the termination resistor, this will increase the level above 10 kHz and create a peak in the response for an even more pronounced "Air" effect.
The output is transformer balanced and fully floating and can drive a 600 ohm load up to level of about 28 dBu.

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.

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.
