AKG CS3 DU 50 - Delegate Unit with 50cm Gooseneck Microphone for CS3 Conference Systems

AKG CS3 DU 50 - Delegate Unit with 50cm Gooseneck Microphone for CS3 Conference Systems

The AKG CS3 DU 50 is a delegate station designed to integrate into the AKG CS3 conference system. It incorporates a 50 cm gooseneck microphone with light ring, internal 2 W speaker and two 3.5 mm headphone outputs to allow listening to up to two participants per seat. It is powered directly from the system base unit via 24 V DC and connects via 8-pin DIN , which simplifies daisy-chaining and guarantees stable connections. Its electronics offer SNR > 80 dB , frequency response 50 Hz–20 kHz and THD < 0.1% , providing voice clarity and high intelligibility even during extended sessions. The push-to-talk (PTT) button with LED signaling controls turn taking and, when the microphone is activated, the system automatically mutes the integrated speaker to prevent feedback.

Main features

• 50cm microphone with LED ring to indicate speaking status.
• Built-in 2W speaker with auto-mute when the microphone is activated.
• Two 3.5 mm headphone outputs (9 dBu), compatible with 8–32 Ω , ideal for sharing a position between two delegates.
• 8-pin DIN connectivity for direct integration into the system bus.
• Power supply 24 V DC supplied by the base unit; consumption 3 W.
• Audio performance : SNR > 80 dB, response 50 Hz–20 kHz, total harmonic distortion < 0.1 %.
• Local controls: PTT button with LED and volume control.
• Robust design for intensive use in meeting rooms, boardrooms and educational centers.
• Compact dimensions : 170 × 143 × 63 mm; weight approx. 1 kg .

Product benefits

• Consistent voice clarity thanks to low distortion and a wide frequency range, improving understanding during debates and voting.
• Intuitive shift management with PTT button and visual indication, reducing interruptions and overlaps.
• Personalized listening via two headphone jacks, useful for supporting interpreters or for sharing a seat.
• Quick and tidy installation with power from the base unit and 8-pin DIN connection, minimizing external power supplies.
• System scalability through integration with the CS3 base unit, allowing multiple workstations to be deployed in the same room.

Use cases

• Corporate meeting rooms and boardrooms.
• Town councils, municipal plenary sessions and local chambers.
• Universities and training centers for panels and tribunals.
• Hotels and convention centers with modular rooms.
