BSS Soundweb London AEC Input Card aec input card

The Soundweb London AEC Input Card is designed to populate any of the four card slots on Soundweb London chassis such as the BLU-800, BLU-805, BLU-806, BLU-320, BLU-325, BLU-326, BLU-160, BLU-120, BLU-80, BLU-32, and BLU-16, giving system integrators a modular way to configure the exact I/O mix required for a given installation.

The AEC Input Card enables Soundweb London devices to cancel acoustic echo that arises when sound from a room loudspeaker is picked up again by a nearby microphone during a conference call. Like the standard Analog Input Card, it offers phantom power configurable per channel and software-controlled analog gain in 6 dB steps from 0 dB to 48 dB.

Each of the four channels provides independent AEC processing with its own individually configurable AEC reference, allowing a single card to support multiple separate conferencing spaces from one device. The card also offers a direct microphone feed for local sound reinforcement, allowing full-bandwidth, low-latency microphone signals to be mixed and processed for the room’s PA system alongside the echo-cancelled conferencing feed.

Each AEC Input Card card provides four channels of acoustic echo cancellation inputs, keeping a consistent channel density across the Soundweb London card range so that chassis I/O can be planned and budgeted predictably. Cards are hot-swappable within a properly powered-down chassis and are secured with captive screws for reliable long-term operation in installed sound environments.

By using field-configurable cards rather than fixed I/O, the AEC Input Card allows a single Soundweb London chassis to be adapted over the lifetime of an installation as requirements change, protecting the integrator’s investment in the core processing hardware while still allowing the physical I/O to evolve alongside the project.
