Yealink CPE40 Professional Conference Microphone
PRODUCT DESCRIPTION
Yealink CPE40 Professional Conference Microphone (1304032) - 2 Years Local Warranty
Expansion Speakerphone for the Yealink CP50
The Yealink CPE40 is the expansion unit for the Yealink CP50 conference speakerphone. Each CPE40 adds another 8-microphone 360° array and a built-in 4W speaker further down the table, so participants in medium and large Singapore boardrooms are picked up — and hear — just as clearly as those beside the main unit.
Single-Cable Daisy Chain, Powered by the CP50
The CPE40 connects to the CP50's Audio port with a single Ethernet-style cable (3 m included) that carries both audio and power — no power adapter at each seat. Two RJ45 ports let units pass through to the next in the chain: up to 3 CPE40s per CP50 with the standard adapter, or up to 7 with the optional 48V/2A adapter.
Same Professional Pickup as the Main Unit
Each CPE40 carries the same 8-microphone omnidirectional array with 6-metre pickup and Yealink's second-generation AI audio processing — intelligent noise, echo and reverberation cancellation with full-duplex audio and AGC — for consistent voice quality along the whole table.
On-Unit Controls That Sync with Your Meeting
Mute and volume buttons on every CPE40 sync with the UC software in use, and the mute LED shows call status at a glance — so anyone at the table can mute the room instantly.

Frequently Asked Questions — Yealink CPE40
Can the CPE40 be used on its own?
No — the CPE40 is an expansion unit that connects to, and is powered by, the Yealink CP50 (1304031). For a standalone speakerphone, consider the CP50 itself or the Yealink SP92.
Does the CPE40 need its own power adapter?
No — power is delivered from the CP50 over the same single Ethernet-style chain cable that carries audio, keeping the table tidy.
How many CPE40 units can I chain to one CP50?
Up to 3 with the CP50's standard 48V/0.7A adapter, or up to 7 with the optional 48V/2A adapter — up to 8 units in total covering long tables.
Is the CPE40's pickup quality the same as the CP50's?
Yes — it has the same 8-microphone 360° array with 6 m pickup, the same 4W speaker, and the same second-generation AI noise, echo and reverberation cancellation.
How far apart should units be placed?
Each unit picks up within a 6 m radius; the included 3 m cable suits typical seat spacing along a boardroom table. SourceIT can advise on layouts for your room size.
Does the Yealink CPE40 come with local warranty in Singapore?
Yes. Every CPE40 sold by SourceIT comes with 2 years local Singapore warranty and a GST invoice.
