Telycam SONO+ — a speakerphone with 8 microphones and support for linking up to 8 units

Maxim Liadov

The Asian company Telecam Technology established the Telycam brand in 2014, after many years of OEM production for other brands. The company develops and manufactures business products, mainly pan-tilt-zoom (PTZ) cameras and webcams.

The new SONO+ speakerphone is designed for meeting rooms of any size. An array of eight microphones, support for linking up to 8 units by USB cable, and a wide choice of connections make the speakerphone suitable for many different setups.

We tested the interesting Telycam SONO+ AI DUAL package. It contains everything needed to set up conferencing in a medium-sized meeting room: two speakerphones, a power adapter, and a long, high-quality USB cable. The cable links the second speakerphone to the first so that the two work together.

Only one speakerphone needs a power connection. The PC connection can be wired or wireless. Along with standard Bluetooth support for PCs and mobile devices, the package includes a wireless USB adapter, or dongle.

Let us look at the specifications.

The eight microphones and wide pickup range of up to 5 meters place this device among professional models for business use. The manufacturer also highlights its Telycam AI Noise technology. This suppresses noise and other unwanted sounds, sending only speech to the remote participant.

All current conferencing applications are supported, including Kontur.Talk, Yandex.Telemost, MTS Link Meetings, Microsoft Teams, Zoom, and others. It is best to disable processing in the conferencing software so that it does not conflict with the more advanced AI processing built into the speakerphone. We tested the speakerphones in Microsoft Teams and had no difficulties.

The speakerphone is fairly tall. This allows the microphones and loudspeaker to be placed as far apart as possible, reducing interference between them. The housing is plastic with a metallic finish. Underneath are — rubber feet and a threaded stand mount. The speakerphone stands firmly and does not slide across the table. The touch buttons provide an audible signal with each press. An English-speaking female voice announces connections and mode changes. When + or - is pressed, a multi-segment LED ring shows the volume level.

Wireless operation and setups with several linked speakerphones use a 15 V, 2.4 A (36 W) mains adapter. We confirmed that a PC's USB-C connection alone, without the extra power adapter, can run only the single connected speakerphone. Mobile devices also connect easily over Bluetooth. The indicator changes from white to blue to confirm the connection.

As usual, we tested the speakerphone in a 5-by-6-meter meeting room and found no problems. The built-in full-range loudspeaker provides loud sound with 5 W of power. We heard no distortion, and the remote participant's speech was clear. The benefits of the built-in sound processing were easy to hear: automatic level control, echo cancellation, and removal of unwanted sounds. We did not need to raise our voices. The person at the other end was also comfortable. The standard controls are easy to use. The crossed-out microphone button temporarily mutes the microphone, for example to cough or drink water. This is useful in air-conditioned rooms. Everything is simple and clear. Illuminated buttons help in low light, such as during projector presentations.

Conclusions

We conclude that Telycam SONO+ — is a modern speakerphone from an experienced manufacturer, with eight microphones and support for linking up to eight units. The package of two speakerphones and all necessary accessories is attractive for medium-sized conference rooms. Any office employee can quickly set up high-quality conferencing without calling professional installers. More speakerphones can be added later if needed. The full-range loudspeaker provides loud, clear sound, while the latest built-in AI processing makes conversations easy and comfortable.
