Digigram PCXpocket

D i g i g r a mDigigram PCXpocketLaptop Sound CardsPROFESSIONAL AUDIO APPLICATIONS ON YOUR LAPTOPy IN 1997, DIGIGRAM PCXPOCKET was the first Type II PCCard for professional audio applications on a laptop.Digigram now offers you a choice Pocket cards witha range of processing power levels and audiointerface configurations.The three Digigram PCXpocket cards are designedprimarily for specialized Digigram Poweredapplications that are written by our developmentpartners to run on the cards’ on-board digital signalprocessors.For standard third-party audio and music productionsoftware on Windows or Mac OS platforms, theDigigram VXpocket (described separately) should beconsidered.■ The PCXpocket v3 has both analog and digitalinputs and outputs.■ PCXpocket 240 and PCXpocket 440 arededicated for multichannel applications.If the possibility of running sophisticated audioapplications on a laptop has sparked yourimagination, this range of cards can turn yourconcept into a reality.Digigram PCXpocketLaptop Sound Cards

D i g i g r a myKEY FEATURES■ All cards are full duplex, offering simultaneous andindependent record and playback capabilities.■ PCM encoding/decoding resolutions are 8, 16, or 24bits.■ All Pocket cards can run applications that complywith Microsoft’s WAVE protocol.■ When using applications based on the Digigram npSDK with the PCXpocket cards:■ Real-time mixing of multiple sound files, leveladjustment, panning, cross fade, punch-in/punchout,scrubbing, time-stretching, pitch-shifting, andformat and frequency conversions are performedon the DSP of the cards.■ Cards perform real-time, simultaneous MPEGLayer I and Layer II compression anddecompression during record and playback.Support provided for Layers I and II of the MPEGAudio standard (ISO 11172-3) and the lowsampling frequencies of the MPEG-2 Audiostandard (ISO 13818-3).■ Cards perform GSM encoding and decoding.■ LTC inputs on the PCXpocket v3 and PCXpocket440 can be used for synchronization.■ Multiple applications may share the resources of asingle card.■ Analog inputs and outputs may be configured asone stereo or two mono channels.■ Interboard synchronization is possible foroperation of two PCXpocket 440s in one laptop.PCXpocket v3Our latest generation stereo model, the PCXpocket v3provides the finest portable audio quality with its 24-bitconverters. Significant on-board DSP enables thePCXpocket v3 to manage a variety of Digigram Powered(np SDK) applications, including those that can takeadvantage of its LTC (SMPTE) time-code input forsynchronization.These applications can perform their audioprocessing on the PCXpocket v3, instead of on thecomputer’s native processor.The PCXpocket v3 is also compatible with the wide rangeof PC software for recording and production that operateunder Microsoft’s WAVE protocol and run on the laptop’sprocessor. It has two balanced analog mono inputs atmicrophone or line level and two balanced analog outputs.SPDIF input and output allow direct digital transfer.A breakoutcable is provided with XLR connectors for the analoginputs/outputs, phono (CINCH) connectors for the digitalinput/output, and a phono connector for the LTC input.Digigram PCXpocketLaptop Sound Cards

D i g i g r a mPCXpocket 240Primarily designed for low bit rate recording applications,such as audio logging, the PCXpocket 240 has four balancedanalog mono inputs and a stereo output for monitoring.Inputs can operate at microphone or line level.When usingan application developed using the np SDK, MPEG (Layer Ior II) or GSM coding is performed on the card’s DSP formaximum recording time. PCM linear is also available forbest fidelity in audio analysis and other uses. DSP-basedprocessing, such as scrubbing, adds to the card’s flexiblefeature set.A unique “Cable Cosse” provides positive connection tothe PC Card on one side and to a fan-out of audio cableson the other. Input connectors are XLR and the outputconnector is a stereo phone jack.Applications using Microsoft’s WAVE API may also be usedwith the PCXpocket 240.PCXpocket 440Digigram is pleased to present our most complete laptopsound card The PCXpocket 440 has four mono (or twostereo) analog inputs and four mono (or two stereo) analogoutputs. In addition, an SPDIF input can be used in place ofthe first stereo input pair and an SPDIF output operates inparallel with the first stereo output pair. If more inputs andoutputs are needed, two PCXpocket 440s can besynchronized in the same laptop.Significant on-board DSP enables the PCXpocket 440 tomanage a variety of Digigram Powered(np SDK) applications, including those that can takeadvantage of its LTC (SMPTE) time-code input forsynchronization.Additional DSP functions enabled by the npSDK include MPEG (Layer I and II) and GSM encoding anddecoding, variable sampling frequency, and sophisticatedaudio processing. The PCXpocket 440 may also be usedwith applications using Microsoft’s WAVE protocol.A unique “Cable Cosse” provides positive connection tothe PC Card on one side and to a fan-out of audio cableson the other.Analog connectors are XLR and the SPDIF andLTC connectors are phono (CINCH).A portable and powerful digital audio workstation iscreated when the PCXpocket 440 is coupled withDigigram’s Xtrack suite of digital audio production tools.Digigram PCXpocketLaptop Sound Cards
