Grandstream GMD1208 Wireless Desktop Conference Microphone, 5 m Pickup

Overview

The Grandstream GMD1208 is a wireless tabletop microphone that extends the pickup of a Grandstream GVC3220 video conferencing system or GAC2570 conference phone, so people at the far end of a long table are heard clearly. It runs on a built-in battery and links to the host device by a 2.4 GHz radio or Bluetooth. It suits larger meeting rooms and boardrooms.

Is it right for you?

• Suits a room where the GVC3220 or GAC2570 on its own does not reach everyone at the table.
• It is an accessory and needs one of those two Grandstream hosts; it does not work as a stand-alone conference phone.
• Up to 2 microphones can be cascaded, and the GAC2570 supports up to two GMD1208 units.
• In Bluetooth mode it can also pair with other Bluetooth devices, and a BYOD (bring your own device) mode works over Micro-B USB.

Key features

• 8 omnidirectional MEMS microphones with dynamic beamforming across 24 beam directions, about 5 m pickup.
• 2.4 GHz link up to 66 ft (about 20 m), or Bluetooth 2.1+EDR mode up to 33 ft (about 10 m).
• Ultrasound pairing with the host device.
• Capacitive mute key with LED on top, and LEDs for low power and mute status.
• 1500 mAh Li-ion battery for about 12 hours of talk time.
• Opus codec. Up to 2 microphones can be cascaded.
• Small and light: 105 x 105 x 16.9 mm, 131.4 g.

What else you need

• A compatible host: the Grandstream GVC3220 video conferencing system or the GAC2570 conference phone.
• A mains socket for charging through the Micro-B USB port; a power adapter (5 V DC 1 A) and USB cable come in the box.

Installation

Place it on the table between the participants and keep it within wireless range of the host device: up to about 20 m in 2.4 GHz mode or about 10 m in Bluetooth mode. Pair it with the host by ultrasound, and charge it through the Micro-B USB port when the low-power LED shows.

Before you buy

• It needs a GVC3220 or GAC2570 host. The GVC3220 already comes with one GMD1208 in its package, so you need this item for a second microphone or for a GAC2570.
• A power adapter and USB cable come in the box for charging.
• Operating temperature 0 to 40 °C.
