MODEL- FIRESTUDIO         VENDOR- PRESONUS AUDIO
    
FEATURES- FireStudio
       26x26 24-bit/96k FireWire Recording System with Optical Lightpipe 
        I/O, MIDI I/O, S/PDIF I/O, Mixer/Router software, and optional
        MSR remote.
       The PreSonus FireStudio is a complete 26x26 24-bit/96k professional 
        recording system combining eight Class A PreSonus microphone 
        preamplifiers, up to sixteen channels of optical ADAT input/output,
        S/PDIF and MIDI input/output, along with the Control Console - a 
        36x36x18 zero latency mixer/router.  The FireStudio also comes with 
        award-winning recording and production software, virtual 
        instruments, plug-ins, drum loops and samples to get you started 
        making music immediately.
* PreSonus Preamplifiers
   The FireStudio starts with eight on-board custom-designed Class A 
   microphone preamplifiers. Many other companies offering recording 
   interfaces add the cheapest possible microphone preamplifier as an 
   afterthought to the interface. PreSonus knows that every major component 
   in the signal path from the audio source to the hard drive are extremely 
   important and the preamplifier is a key component. The job of a 
   microphone preamplifier is to boost microphone level signals to line 
   level so that the signal can be converted from analog to digital. This 
   mic to line boost is generally an preamplification of over 400 times the 
   voltage of the original mic level signal. This preamplification stage is 
   one of the most important stages that the signal will go through before 
   converted to digital, and is why a high performance preamplifier is 
   important to achieving great results. A cheap "off the shelf op-amp" 
   type mic preamp that is found in most interfaces translates into thin, 
   noisy and harsh results. A PreSonus preamplifier which operates in Class 
   A mode and at higher voltage/current ratings than off the shelf op-amps, 
   is designed for high headroom, low noise, wide dynamic range and wide 
   frequency range, and most importantly, musicality and transparency - 
   smooth highs, solid deep lows, and everything in between.
* Ins and Outs
   The FireStudio is loaded with I/O for an extremely flexible and 
   expandable recording system. The FireStudio starts with eight Class A 
   customer designed PreSonus microphone preamplifiers. You can add 
   additional preamplifiers or analog inputs via the dual optical light 
   pipe ports on the rear panel. You add up to two DigiMax FS, for a total 
   of twenty-four microphone preamplifiers all in only three rack spaces! 
   Additionally word/clock I/O for ultra tight synchronization, MIDI I/O 
   and SPDIF I/O are on the FireStudio for further expandability.
* JetPLL 
   The sycronization of the FireStudio is handled by patented JetPLL jitter 
   reduction technology. JetPLLTM incorporates noise shaping to virtually 
   remove all audio band jitter. JetPLLTM ensures the highest converter 
   performance possible, resulting in better stereo separation and clearer 
   more transparent audio. JetPLLTM delivers ultra-fast locking to any 
   digital format, through a wide range of frequencies and is extremely 
   robust, and tolerant of wide variations in clock frequencies. JetPLL 
   ensures near perfect clock performance when networking audio devices 
   thus creating the most stable and robust synchronization to the computer 
   and all devices synchronization with the FireStudio.
* Control Console - Zero Latency DSP Mixing/Routing
   The FIRESTUDIO also includes the Control Console - a 36x36x18 DSP 
   mixer/router for flexible mixing and direct routing any input to any 
   output including the headphone output, with zero latency. The Control 
   Console software application lives between your FireStudio interface and 
   your DAW software enabling the mixing and routing of input streams 
   coming into your FireStudio interface and playback stream coming from 
   your DAW software. The Control Console is capable of creating up to nine 
   stereo mixes and then routing to the outputs of your FireStudio for 
   headphone mixes and various aux sends. This way everyone in the band and 
   the recording engineer can have a custom mix.
* Optional Monitor Station Remote (MSR)
   The optional MSR (monitor station remote) for the FireStudio is a 
   complete surround/stereo speaker manager, input switcher and 
   communication system delivering a more efficient and flexible work flow. 
   The MSR connects to the FireStudio via standard Cat 5 Ethernet cable to 
   keep your work space as clean as possible. There are also two headphone 
   outputs on the FireStudio for even further flexibility and convenience.
* ProPak Complete Software Suite
   The PreSonus FireStudio also comes with the new ProPak Complete Software 
   Suite, which includes more than 20 real time plug-ins, a number of 
   virtual instruments and over 2 GB of drum loops and samples including: 
   Steinberg - Cubase LE; Propellerheads Reason Adapted PreSonus Edition; 
   IK Multimedia - Amplitube LE; FXpansion - BFD lite; Drumagog LE; Sonoma 
   Wire Works-Riffworks Jr.; Wave Arts -- TrackPlug LE, MasterVerb LE and 
   more!
