Building on this legacy, we created a separate digital volume-control circuit ahead of our analog XMAX preamp design, providing the convenience of digital recall without sacrificing fidelity. In 1995, PreSonus patented digital control over analog circuits with our first studio product. The XMAX preamps in StudioLive RM-series mixers offer another advantage: They are recallable. As a result, you’ll experience better stereo separation and clearer, more transparent audio. JetPLL quickly locks to any digital format through a wide range of frequencies and is extremely robust and tolerant of wide variations in clock frequencies. JetPLL incorporates noise shaping to virtually remove all audio-band jitter, ensuring near-perfect clock performance and optimal converter performance when networking two or more digital-audio devices. Once the signal is precisely converted to the digital domain by high-quality Burr-Brown converters, synchronization to your computer is stable and robust, thanks to JetPLL synchronization technology. 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. Our discrete design delivers ultra-low noise and transparency. Op-amps add noise, coloration, and harshness to a signal. We only use genuine transistors, resistors, and capacitors. Higher-voltage power rails deliver more headroom, deeper lows, smoother highs, and a richer overall sound. Most off-the-shelf, op-amp-based designs run on power rails of 10V to 18V. The XMAX preamplifier runs on power rails of 30V. 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. XMAX preamplifiers are built with three key elements: But with XMAX preamps, the sonic quality is limited only by the microphone you plug into it. A cheap, off-the-shelf, op-amp-type mic preamp delivers thin, noisy, harsh results. 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. The job of a microphone preamplifier in a digital mixer is to boost a microphone-level signal to line level before conversion to the digital domain. We start with a great microphone preamplifier. And while you don’t have to create IP addresses, you can manually assign static IP addresses if you wish. Simply open port 47809 to let AI control network traffic through. We gave you that capability, too: The networking backbone of PreSonus AI technology is registered with IANA (Internet Assigned Numbers Authority). That said, we understand that corporate, educational, and government environments require secured, firewalled networks, which requires some expertise. You never have to create an IP address or enter a subnet mask, or even know what those are. Your wired networked devices connect with lightweight CAT5e or CAT6 Ethernet cable, eliminating bulky, expensive analog snakes. ![]() We made networking an RM-series mixer as easy as possible. Whether you choose AVB or Dante, you can control your RM mixer from a Mac or Windows PC and from a StudioLive CS18AI control surface. ![]() Or go with Dante to send and receive networked audio for multitrack recording and connect to hundreds of Dante-enabled products-including Macs and Windows PCs running Audinate’s Dante Virtual Soundcard software and PreSonus StudioLive AI-series loudspeakers and WorxAudio loudspeakers that are equipped with a PreSonus SL-Dante-SPK option card. ![]() Use AVB to cascade two RM-series mixers to create a larger system or connect the RM mixer to a StudioLive AI-series front-of-house console use the RM32AI as a stage box and monitor mixer and send audio to and from a StudioLive CS18AI control surface. Each StudioLive RM-series mixer comes equipped with an AVB network card that can be replaced with an optional Dante card.
