DU44

What the DU44 does in a conferencing chain

The AISPEECH DU44 bridges a computer or conferencing device connected over USB with a Dante audio network. Audio from a meeting platform can reach amplifiers, DSPs and loudspeakers on the Dante side, while microphone signals can return to the PC. Because the unit runs without drivers, it can be brought into a room quickly during commissioning.

Channel count, mixing and latency

The DU44 provides four Dante inputs, two Dante outputs, two USB inputs and two USB outputs. Its built-in matrix mixing lets you combine and route these channels inside the device, which reduces the number of external mixer inputs a room needs. Audio runs at a 48 kHz sampling rate with 16-bit, 24-bit or 32-bit depth, and latency can be set to 1 ms, 2 ms or 5 ms so the setting can match the room requirements.

• Visual configuration software manages audio subscriptions and functional settings.
• Firmware upgrade and an open API are listed as supported features.
• One RJ45 port and one RESET button are provided on the unit.

Pairing with the AIMIC-MCS06 ceiling microphone

The DU44 is designed to work with AISPEECH high-end microphones, and it is integrated with the AIMIC-MCS06 all-in-one ceiling microphone, which has built-in pickup and Voice Lift. Dante AutoRouting is supported with the MCS06, and up to two MCS06 units can be routed and mixed through one DU44. This reduces manual patching during deployment. Auto-Routing is listed for the MCS06 only, so confirm routing requirements for any other device with the SmartRooms Qatar team.

Where it fits in Qatar

In a boardroom in West Bay or Msheireb where the Doha team joins a call with colleagues abroad, a DU44 can take the room PC audio and feed the Dante network that drives the ceiling speakers, while an MCS06 captures voices across the table. In a lecture theatre at Education City, the same chain lets a lecturer laptop feed a hybrid session. For a government ministry in Doha upgrading several meeting rooms, one adapter per room keeps each system self-contained and easier to commission.

Planning points before you order

• The operating range is 0 to 40 degrees Celsius. Qatar summers can exceed 45 degrees, so keep the unit in an air-conditioned space and confirm the temperature of any ceiling void or cabinet.
• Power comes from USB or PoE, so confirm the power source for each location.
• At 138 mm by 42 mm by 26.5 mm and about 200 g, the unit needs a fixing point. The datasheet does not list a mounting kit, so confirm the method before ordering.

SmartRooms Qatar offers free site surveys, professional installation and delivery to all eight municipalities of Qatar. Organisations ordering through a purchase order or a government tender can request a quotation, which is usually issued within one working day. Request a quote for the DU44 and tell us which microphones and rooms you are planning, and our team will confirm the configuration.
