Digigram VB2201A0401 overview

  • 1Description

With up to 32 inputs/outputs, the Digigram EtherSound PCI Express Sound Card combines the widely used EtherSound technology for distributing real-time audio over Ethernet. It allows professional audio software applications to access the EtherSound networks.

This sound card is suitable when direct-to-disk applications need to play and/or record selected ES-100 audio channels without jeo­pardizing flexibility.

The Digigram EtherSound PCI Express Sound Card comes with DirectSound and ASIO drivers. These drivers can transmit and receive up to 32 EtherSound channels, thus connecting professional audio software to any 100 Mb/s EtherSound network for a wide range of applications.

In a live environment, using 100 Mb/s EtherSound as the ultra-low latency audio distribution system, the ability to receive up to 32 channels from an EtherSound-ready mixing console and recording them straight onto a computer’s hard disk for mix down at a later date, offers a highly cost-effective solution for multi-channel recording and a solution for musician replacement during sound checks.

With the ability to record many channels from different locations, the PCI Express Sound Card is a suitable solution for logging applications and surveillance monitoring. For hotels, conference centers, and other multi-room venues, this sound card has the ability to play back up to 32 stereo music programs from just one PC or 32 in mono mode.

In broadcast installations, the PCI Express Sound Card supports Digigram analog and digital EtherSound interfaces, offering a compelling solution for multi-channel audio delivery and distribution in and between studios via standard Ethernet.

PCI Express Card

  • Links a computer directly to an EtherSound network using standard drivers
  • Short length PCI card
  • Inputs: 32 EtherSound channels
  • Outputs: 32 EtherSound channels
  • Audio format supported: PCM 24 bits; 44.1/48 kHz
  • Low-latency DirectSound and ASIO drivers
  • Word Clock input / synchronization
  • I/O routing remotely controllable via EScontrol or other applications using the EtherSound SDK
  • EtherSound ES-100 firmware makes it compatible with the EtherSound redundant ring topology


Applications: Suitable for broadcast, live, installed sound, and recording applications
  • Direct recording in installed live sound and touring
  • Logging
  • Playback in fixed installations
  • Multichannel broadcasting
  • EtherSound


EtherSound ES-100 Firmware

Channel Count (at 44.1/48 kHz)
  • Per 100 Mb/s cable: Up to 32 channels in each direction
  • Per system: Total channel count may exceed 128 by overwriting existing channels in parts of the network
  • All channels are independent from one another
  • In bi-directional daisy-chains all channels are available to all nodes
  • In star architectures or uni-directional daisy-chains, all channels are available to all nodes downstream of the input


Audio Clock
  • All devices are synchronized from the clock reference of a master device on the network
  • Phase can be recovered using a distributed Word Clock source


  • Network Latency (SSI in to SSI out): 104 µs (five samples at 48 kHz)
  • Independent from the number of channels
  • Additional latency per device in a daisy-chain: 1.4 µs
  • Additional latency per switch: 5 to 20 µs
  • Overall latency, including A/D and D/A conversion: 1.5 to 2 µs
  • EtherSound is deterministic with stable latency: delay and phase between any two nodes can be calculated


Ethernet Standard Compliance
  • Fully IEEE 802.3x compliant
  • Operational with standard Ethernet network layer 1 & 2 components (cables, fiber optics, switches, media converters, and more)


Control & Monitoring Data over the Same Cable
  • Network remote control through embedded control data
  • Standard control software with multi vendor support: EScontrol
  • Control application generator with multi vendor support via strategic partnership with Stardraw.com
  • ES command port for microcontroller based control system


Network Architecture
  • Daisy-chain / Redundant ring
  • Star through Ethernet switches
  • Combination of daisy-chain and star


  • EtherSound enabled products are available from a number of leading audio equipment manufacturers for installed sound and pro audio applications
  • All products can operate as a unified system on the same network, exchanging audio, and control signals
