BSS BLUAEC-IN – 4-Channel AEC Mic/Line Input Card

Product Overview

The BSS BLUAEC-IN is a 4-channel Acoustic Echo Cancellation (AEC) mic/line input card designed to populate the card slots of Soundweb London chassis devices, including the BLU-800, BLU-805, BLU-806, BLU-320, BLU-325, BLU-326, BLU-160, and BLU-120. Purpose-built for conferencing and collaboration environments, this AEC input card eliminates acoustic echo that occurs when loudspeaker output re-enters open microphones in the same space. For integrators deploying Soundweb London conference room audio processing, the BLUAEC-IN provides full-featured echo cancellation, noise reduction, and automatic gain control within the existing chassis — no additional hardware required.

Product Description

The BSS BLUAEC-IN Acoustic Echo Cancellation input card installs directly into any of the four card slots found on compatible Soundweb London chassis devices, making it a natural upgrade path for existing installations. Four independent AEC channels can be freely configured in HiQnet Audio Architect software, with each channel supporting an individual AEC reference — enabling a single device to address multiple conferencing spaces simultaneously. Like the standard Soundweb London Analog Input Cards, the BLUAEC-IN provides per-channel Phantom Power and software-controlled analog gain adjustable in 6 dB steps from 0 dB to 48 dB, maintaining consistency across the card family. Automatic Gain Control (AGC) keeps microphone input levels at an optimum point regardless of talker distance or room variation. Noise Cancellation (NC) targets steady-state background noise sources — projector fans, HVAC systems, and similar — and removes them from the signal path before processing or transmission. Non-Linear Processing (NLP) dynamically compensates for residual echo in situations where acoustic conditions push the cancellation algorithm toward under- or over-correction. A direct microphone feed path allows full-bandwidth, low-latency signals to be mixed and processed separately for local sound reinforcement, keeping the far-end signal clean while serving in-room listeners. The BLUAEC-IN is configured and monitored exclusively through HiQnet Audio Architect, consistent with the broader Soundweb London ecosystem. This card is the correct solution for conference rooms, boardrooms, government hearing spaces, and training rooms where intelligibility and echo-free communication are non-negotiable requirements.

Key Features

• 4 Independent AEC Channels — Each channel operates independently, allowing simultaneous echo cancellation across multiple mic inputs in a single card slot.
• Individual AEC References Per Channel — Supports multi-room or multi-zone deployments from a single Soundweb London device.
• Automatic Gain Control (AGC) — Continuously adjusts microphone input gain to maintain consistent levels regardless of talker position or room acoustics.
• Noise Cancellation (NC) — Removes steady-state background noise such as HVAC or projector fan noise from the signal path prior to transmission.
• Non-Linear Processing (NLP) — Dynamically addresses residual echo caused by under- or over-cancellation in challenging acoustic environments.
• Phantom Power Per Channel — Software-controlled 48V phantom power available on each channel for condenser microphones.
• Software-Controlled Analog Gain — Adjustable in 6 dB steps from 0 dB to 48 dB via HiQnet Audio Architect.
• Direct Mic Feed for Local Reinforcement — Full-bandwidth, low-latency direct microphone path for in-room sound reinforcement independent of conference processing.
• Compatible with Soundweb London Chassis — Designed for BLU-800, BLU-805, BLU-806, BLU-320, BLU-325, BLU-326, BLU-160, and BLU-120.
• HiQnet Audio Architect Configuration — Full software control, monitoring, and drag-and-drop configuration within the familiar Soundweb London design environment.

Technical Specifications

Frequently Asked Questions

Q: Which Soundweb London chassis are compatible with the BLUAEC-IN?

A: The BLUAEC-IN is compatible with BLU-800, BLU-805, BLU-806, BLU-320, BLU-325, BLU-326, BLU-160, and BLU-120 chassis. It occupies one of the four card slots available on these devices.

Q: How many BLUAEC-IN cards can be installed in a single chassis?

A: Up to four cards can be installed in a single Soundweb London chassis (depending on chassis model), providing up to 16 AEC input channels per device.

Q: Can the BLUAEC-IN address multiple rooms from a single device?

A: Yes. Each channel supports an individual AEC reference, so a single card can serve multiple conferencing spaces with independent echo cancellation per channel.

Q: Does the BLUAEC-IN require separate configuration hardware or software?

A: No. Configuration, control, and monitoring are handled entirely through HiQnet Audio Architect software. No additional hardware interface is needed.

Q: What is the purpose of the direct microphone feed feature?

A: The direct mic feed provides a full-bandwidth, low-latency path for local sound reinforcement, separate from the conference signal chain. This allows in-room speakers to receive clean mic audio without the delay introduced by AEC processing.

Q: Does the BLUAEC-IN support condenser microphones?

A: Yes. Per-channel software-controlled Phantom Power is available on all four channels, supporting standard condenser microphones used in professional conferencing installations.

Q: What warranty and support options are available?

A: BSS Audio products are backed by the HARMAN Professional Solutions warranty program. Technical support is available through BSS Audio support channels. Contact Creation Networks for purchasing assistance and pre-sales consultation.
