User’s manual
FEATURES
PCX-IP LW881e and PCX-IP LW1221e are sound cards for use with Axia Livewire™ systems, with PCI EXPRESS
TM
(PCIe
®
) bus
interface. They are in PCI EXPRESS
TM
x1 format and can thus be plugged into any PCIe
®
slot (x1, x4, x8, x16).
PCX-IP LW881 main hardware features
● 1 RJ-45 Ethernet port allowing for extraction of up to 8 mono channels from the Livewire network, and insertion of up to 8 mono
channels in the Livewire network
● 1 Sub-D 9 pin connector for 5 physical GPI / 5 physical GPO transmitted through the Livewire network.
● 48 kHz sampling frequency
● Several cards can be plugged in one PC
PCX-IP LW1221 main hardware features
● 1 RJ-45 Ethernet port allowing for extraction of up to 2 mono channels from the Livewire network, and insertion of up to 12 mono
channels in the Livewire network
● 1 Sub-D 9 pin connector for 5 physical GPI / 5 physical GPO transmitted through the Livewire network.
● 48 kHz sampling frequency
● Several cards can be plugged in one PC
Main software features
● Real-time, simultaneous record and playback in PCM (8, 16 and 24 bits) as well as in MPEG Audio Layer I, Layer II and Layer III*,
Float IEEE754 conversion supported (with 24-bit fixed-point dynamic range)
● When using the Digigram np SDK, real-time mixing of several PCM and MPEG audio streams per output channel, direct monitoring,
level adjustment, panning, cross-fades, punch-in/punch-out, scrubbing, time-stretching, pitch-shifting, 3-band parametric equalizer,
Maximizer, format and frequency conversions.
● Low latency WDM DirectSound, Wave, and ASIO drivers. Under DirectSound and ASIO, the cards operate in PCM mode only
(nevertheless, an application can integrate coders/decoders on the host PC).
Under Wave, HR boards can operate in both PCM and MPEG (layer 1 and layer 2).
*
MPEG Layer III play-only on DSP
MPEG Layer III recording on the host computer is available through Digigram’s PC Codec using the np SDK
