PRESONUS DIGIMAX 96k 8CH. MIC PREAMP.w-LIMITER and MULTIPLE DIGI

Now with 96k sampling rate*, the DigiMAX is the newest member in the award winning
family of Presonus mic preamp's. Combine eight channels of pristine mic preamplification
with 24 simultaneous digital and analog outputs, and the DigiMAX 96k seamlessly fits
into any digital recording situation. The DigiMAX 96k is the perfect front-end for DAW's as
well as adding mic pre's to digital mixers and sound cards.
A MIC PRE WITH HERITAGE
We started with the same design as the MP20, M80 and VXP: Class A Discrete Input Buffers
followed by a dual-servo gain stage giving you 60db of preamp gain with 52db of headroom. The
DigiMAX 96k is electronically balanced and features phase reverse on the first two channels, as
well as a 20dB pad and selectable 48v phantom power on each channel. A unique feature is EQ
Enhance? which contours the EQ curve -4dB centered at 1k from 250Hz to 5kHz. This is especially
helpful on drum overheads and other sources to bring out definition and notch out problem frequencies.
THE COMPRESSOR TRAPPED IN THE BODY OF A LIMITER
What makes a limiter musical? Typically, most limiters use peak detection which actually clips the
signal and can produce nasty artifacts. RMS detection, though commonly used with most compressors,
has the drawback of not being fast enough to catch extremely fast transients. The DigiMAX 96k uses
both RMS and Peak detection to give you the best of both worlds. The DigiMAX 96k uses an RMS style
compressor with a high ratio while the peak portion is used only to protect the input of the A/D converter
from clipping. The end result? Fast, musical, natural and able to catch anything you throw at it.
CONNECTIVITY FOR DAYS
The DigiMAX 96k features more I/O options than any mic pre on the planet! 8 XLR Mic Inputs + 2 1/4"
Instrument Inputs. The outputs consist of 8 balanced TRS analog outputs plus a 24 bit ADAT? lightpipe
output AND (4) stereo RCA SPDIF Digital Ouputs (Unit ships in AES/EBU mode, breakout cable not included).
And here's the best part... They all work simultaneously! The Ultimate Live Recording Preamp! Use the
ADAT? Lightpipe Outputs to feed your recorders digital inputs while you send an identical signal to a FOH
Console via the TRS Analog Outputs. Bye, bye latency! Use the TRS analog outputs to monitor tracks while
you send the Lightpipe to your soundcard or standalone computer interfaces like MOTU 2408 and Digi001.
Mixer Beefer-Upper! Add high gain/low noise quality micpre's to your digital console using either Lightpipe,
AES/EBU, SPDIF, or analog TRS outputs.

* Over AES/EBU or S/PDIF digital output cables ONLY.

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.

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.
