INTRODUCTION
PCM64 Key Features
PCM64 is a professional sound card in PC card (PCMCIA type 2) format
Its features meet professional sound recording and musical application requirements, bringing Sound
Studio possibilities to the Notebooks.
4 channels audio out, 2 channels audio in and digital audio
You can enjoy quadriphony listening from your notebook and connect it to your digital audio recording
equipment through the S/PDIF adaptor box (optional). The PCM64 has a built-in surround processor
and is ready for future applications like Dolby Pro-Logic® and Dolby AC-3®, without compromising
on two speakers. Of course, you can play and record simultaneously.
Effect processor
PCM64 provides 16 reverb/chorus programs, a 4 band stereo equalizer and a surround 2/4 channels
system.
Those effects can be applied on all the sound devices: Wave table, DSP waves, Line input.
Wave Table Synthesis
1M samples RAM Wave Table CleanWave8® will make your MIDI sequences sound realistic. The
PCM64 is compatible with the Down Loadable Sound standard (DLS) allowing sound banks from
different vendors to be downloaded.
Professional Synthesizer
On card 2M byte DRAM enables the DSP to download and edit instruments. This lets you use the
PCM64 as a professional synthesizer/sampler.
Direct To Disk
The PCM64 provides DtD full duplex capabilities with 8 stereo play waves with individual volume,
panoramic, pitch, filter, reverb and chorus controls and one stereo record track.
(Simultaneous play wave count is subject to the notebook hard disk performances).
Direct Sound Ready
The PCM64 is ready to support Microsoft Direct Sound Features. This includes:
- Hardware mixing of multiple waves (up to 32 waves)
- On board memory buffer to support static wave buffer
- 3D & interactive audio positioning (4 speakers outputs, Doppler for interactive effect)
Upgradable
Being only RAM based, the PCM64 design is open to third party firmware.

Wave Table Synthesis
The high quality wave table synthesis provides 32 midi channels with 64 maximum voices of polyphony (according
to the configuration).
The 24 dB resonant filter and the audio CD quality samples provides professional synthesizer sound quality.
The 2M bytes on board DRAM allows to download high quality GM factory sound bank or third party DLS sound
banks (through the provided Sound Bank Editor).
DSP Waves
The DSP waves ensures the high quality required by professional applications.
Multi waves for DtD (Direct to Disk) applications: 8 stereo play tracks + 1 stereo record track simultaneous.
High quality wave due to the interpolation and the digital filter
Up to 65KHz sampling rate with 8/16 bits mono/stereo format, (44.1 KHz nominal sampling rate).
Individual send to the reverb and the chorus effects provided by the DSP mixer.
DSP Mixer
The DSP Mixer provides for all inputs an individual volume, panoramic , reverb and chorus send:
•32 mono inputs: Wave table
•8 stereo inputs: DSP waves
•1 stereo input: Line In
Line input provides an additional echo with effect volume delay and feedback control.
DSP Waves record
This device records DSP mixer output including reverb & chorus in 8/16 bits mono/stereo format up to 44.1KHz
sampling rate.

PCM64 PC card User’s guide 8
Reverb Chorus
Reverb and chorus are compatible :
•8 Reverb programs, effect volume, time and feedback controls.
•8 chorus programs, effect volume, delay, feedback, rate and depth controls.
Equalizer
Stereo four band parametric equalizer with +/- 12 dB band level
Surround
Surround processing enables to expand stereo image of a stereo signal or to create a pseudo stereo image from a
monophonic source. Surround operates on 2 or 4 speakers configuration.
The PCM64 surround processing involves a delay line that enables to creates actual 3D sound unlike most of the
products that claim to offer 3D sound.

DREAM Media Player
The DREAM Media Player Provides control on the Audio functions through a user friendly interface.
The Player is composed of 4 elements:
•The Mixer
•The Wave player
•The Midi player
•The Audio CD player (if applicable to notebook)
Each media player unit (Wave / Midi / CD) can operate in two different modes:
•Individual selection Song played one by one, push the open button on the player.
•Program selection Song played from a play list, push the prog button on the player (previously open or
create a program list)
Midi Player
The Midi Player can play *.mid and *.rmi files. *.rmi is the Microsoft file format for midi file, it allows to include
additional information into the midi sequence. Dream uses this format to include the wave table sounds into the
sequence. The sounds are downloaded into the card when opening the sequence.
*.rmi examples are provided in the installation disks.
