ANG-2200 Acoustic Noise Generator

The ANG‑2200 generates a perimeter of random acoustic noise to defeat eavesdropping devices (e.g., wired microphones inside walls, contact microphones, audio transmitters in AC outlets, laser/microwave reflections from windows).

Two independent channels, each with:

• Truly random noise source.

• High and low‑frequency controls to compensate for material composition of structures.

Output & load specs:

• Output voltage: ~12 Vp‑p at 6 Ω (minimum load ~2 Ω) for one version.

• Frequency range: 125 Hz – 4 kHz (in many spec sheets) though some list up to 5.6 kHz.

Power: 15 V DC @ 1 A; AC adapter provided (120/240 V) in most cases. Physical: Dimensions approx 1.6″ × 5.5″ × 8″ (4.1 × 14.0 × 20.3 cm); weight ~590 g (1.3 lb).
