Non-contractual photos

The visuals on this page are supplied by the manufacturer. They are frequently produced for a whole range — not for the exact model you are viewing: what you see in the photo is never a promise of what is included.

No exchange, return or cancellation will be accepted on the grounds that something seen in a photo (accessory, port, colour, keyboard layout, packaging…) is not found on the delivered product. Only the specifications written on the page are binding for the order.

What the image does not guarantee:

  • Staging : the rooms, screens, participants and computers photographed are there to illustrate use: they are not included.
  • Accessories : tripod, remote control, table unit and cables are supplied only if the specifications say so.
  • Specifications : resolution, field of view, zoom, built-in microphone and privacy shutter depend on the reference.
  • Colour : one image often serves several colours, and the shade you see depends on studio lighting as much as on your screen settings; the colour sold is the one in the title and the specifications.
  • Props and accessories : the items shown around the product (cables, stands, decorative objects, content displayed on screen) are not included unless explicitly stated.
  • Packaging : boxes, labels and bundles change with the manufacturer's revisions: the packaging delivered may differ from the one in the photo.

What is binding: the product title, this page's technical specifications, the description and, when provided, the manufacturer's PDF datasheet available in the downloads.

The slightest doubt about a specification? Contact us before ordering and we will check for you.

Frequently asked questions about this product

Which system is this Grandstream GMD1208 microphone an add-on for?
The Grandstream GVC3220 Ultra HD multimedia conferencing system, whose audio coverage it extends. It also pairs with Bluetooth devices for HD voice.
What area does the GMD1208 cover?
360 degrees around it, up to 5 metres away, with eight omnidirectional MEMS microphones and dynamic beamforming across 24 directions.
What is the battery life of the GMD1208 microphone?
12 hours of talk time, from a built-in lithium-ion battery that is recharged via the micro-USB port. An indicator warns of low battery before it cuts out.
How do you pair the GMD1208 with the system?
By ultrasound: the microphone and the base recognise each other without any codes to enter. The link then runs over the proprietary 2.4 GHz mode or over Bluetooth.
How many GMD1208 units can be linked together?
Two at most, daisy-chained. This is the limit to know before equipping a very large table: beyond it, rethink the layout rather than add more mics.
How do you mute the GMD1208?
With a touch button on the top, and a two-colour indicator that makes the mute status visible from a distance. Two other indicators show the status and power.
What audio processing does the GMD1208 apply?
Noise reduction and automatic gain control, with the Opus codec. Automatic gain evens out loud and quiet voices around the table without any intervention.
How much space does the GMD1208 take up on the table?
105 × 105 mm and 16.9 mm high, 131.4 g: a flat square, discreet enough not to block the view between participants sitting opposite each other.
Is this Grandstream GMD1208 microphone new and under warranty?
Yes, it is a new Grandstream product, reference GMD1208. The invoice serves as the warranty document, for 1 year. Datasheet: Grandstream GMD1208.
