Anchor PRO MAG2000 Microphone Auto-Booster

Product drawing

The MAG Microphone Auto Booster employs AFC (Adaptive Feedback Cancellation) technology and AGC (Automatic Gain Control) technology.
It’s developed due to the following concerns:

  1. Short microphone pickup distance

  2. Low volume and weak on-site sound reinforcement

  3. High complexity and costly equipment tuning

  4. Significant audio quality degradation caused by existing feedback suppressors

Working Principle

This device abandons traditional outdated feedback suppressors or frequency shifters to eliminate howling. While such technologies can marginally increase system transmission gain (2–3 dB), their limited chip processing capabilities cause noticeable voice distortion and pitch alteration, directly degrading sound quality. Instead, the MAG2000 utilizes an intelligent dynamic feedback filter. Leveraging next-generation high-speed floating-point processing for feedback elimination, it effortlessly boosts system transmission gain by 11 dB—2–3 times higher than conventional devices—while preserving original sound quality.

Key Advantages

  1. Significantly extends microphone pickup distance** – Doubles or triples the effective pickup range at equivalent sound pressure levels;

  2. Dramatically enhances sound reinforcement** – Increases sound pressure level by over 11 dB at identical distances;

  3. Plug-and-play operation** – No software tuning required. With self-adaptive feedback algorithms, the system achieves stable feedback-free operation within 10–30 seconds after connection, delivering an 11 dB transmission gain increase;

  4. Zero audio quality compromise – Maintains lossless sound reproduction for both human voices and music.

Debugging Key Points

  1. Two Connection Methods for MAG2000:
    Direct connection: Microphone signals from the mixer/daisy-chained conference host → MAG2000 → Processed signals output to downstream devices (e.g., mixing console, media matrix).
    Parallel connection: Send microphone signals via console group output → MAG2000 → Processed signals return to console → Amplifier.

  2. For Daisy-Chained Conference Systems/Condenser Mics:
    Disable built-in feedback suppression in conference hosts/mixers (some high-end mixers include DSP processing). If unable to disable, connect to unprocessed auxiliary outputs to avoid sampling errors affecting performance.

  3. System Stability:
    Avoid operating at threshold limits. Maintain 2–3 dB headroom to ensure stability during unexpected events (e.g., object drops, sudden loud sounds).
