Without a quality preamp, the expression “garbage in, garbage out” is especially apt. And customers and reviewers alike have long insisted that the PreSonus XMAX™ Class A solid-state preamp is the finest in its price class.

Presonus 8 Channel Pre Amp

The DigiMax D8 provides eight of these prized preamps—enough to raise your entire studio rig to a higher level. And that’s just the beginning of the story.

Show full description »

The DigiMAX D8 featuring 8 Class A XMAX mic preamplifiers, 8 direct analog outputs, and ADAT optical light pipe connectivity, making it the perfect solution to add 8 professional microphone preamps to any digital recording system or digital mixer with ADAT input including PreSonus FireStudio, DigiDesign’s HD and 003 systems, RME, Mackie and any many others.

Xmax Amp Presonus D8

At PreSonus, we know that the mic preamplifier is a key component in the sonic quality of a recording. Many other companies that offer mobile recording interfaces add the cheapest possible microphone preamplifier as an afterthought.

In contrast, the DigiMax D8 includes custom-designed, high-voltage, discrete, XMAX Class A microphone preamplifiers that are suitable for use with all types of microphones.

The job of a microphone preamplifier in an audio interface is to boost a microphone-level signal to line level before conversion to the digital domain. A good preamp boosts the level to almost 400 times that of the original signal, making the preamp one of the most important stages in an interface. A cheap, off-the-shelf, op-amp-type mic preamp delivers thin, noisy, harsh results.

But with XMAX preamps, the sonic quality is limited only by what microphone you plug into it.

XMAX preamplifiers are built with three key elements:

 

  • High Voltage. The XMAX preamplifier runs on power rails of 30V. Most off-the-shelf, op-amp-based designs run on power rails of 10V to 18V. Higher-voltage power rails deliver more headroom, deeper lows, smoother highs, and a richer overall sound.
  • Discrete components—not op-amps. We only use genuine transistors, resistors, and capacitors. Op-amps add noise, coloration, and harshness to a signal. Our discrete design delivers ultra-low noise and transparency.
    Class A. Class A circuits have no crossover distortion and deliver purer, clearer, and more musical results than the Class AB designs that are found in many preamps.
  • The net result of the XMAX preamp design is high headroom, low noise, wide dynamic range, extended frequency response, and—most important—musicality and transparency, with smooth highs, solid deep lows, and everything in between.

The Lightpipe Kid

With its eight XLR mic inputs and eight ¼” balanced, direct channel outputs, you can route each channel’s signal independently. This makes the DigiMax D8 a premium front end for virtually any system.

 

And thanks to its eight-channel, 24-bit ADAT Lightpipe output (which operates at 44.1 or 48 kHz), the DigiMax D8 provides an excellent front end for Lightpipe-equipped digital-audio devices, such as Avid's Digi 003. You’ll immediately hear the improvement.

Better yet, add a DigiMax D8 to a Lightpipe-equipped PreSonus AudioBox 1818VSL. This combination provides a two-rackspace rig with 16 XMAX-equipped recording channels—enough to record an entire live band.

To keep your digital audio in sync with ultra-low jitter, the D8 receives word clock at its BNC connection and sends word clock via Lightpipe.

Price Matching

Dolphin Music brings you the best music gear at the best price. We are committed to superior customer service and have extensive product knowledge. However, in today’s market we may not always be aware of all the price fluctuations of the products we sell. So, we offer competitive price matching.

Please fill in the following form to request a price match.

What prices we will match?

We will compare prices for new, direct from manufacturer items, excluding any add-ons, options, or other special features which may affect price.

The item must be new and must be the exact same make and model (ie, the same size, version, etc.).

Since our postage charges are lower than most of the shops, the comparison price must be a "delivered cost" to the consumer.

If we are unable to verify the previous condition, we will notify you that we require additional information to verify the Price Match request. Our goal is to make this policy simple and hassle-free. We are committed to responding to your requests quickly.

The price you have found must be the Internet Retailer's regular, advertised price for a current and available item. The price you found cannot be a closeout, discontinued, blemished, year-end, inventory reduction, or any other type of advertised sale price.

Price Matching requests may not be combined with any other promotional discounts, specials or other price incentives.

Prices and price sources you have found which do not meet the above criteria or in which incomplete or inaccurate information is provided to us, will not be approved for our Price Match.
