recording / streams. Instructions in setting the Stream Mix as the input
device for your streaming software may vary. -
Playback Mix. Allows you to listen to all channels using the selected playback device. The 3.5 mm headphone port of the microphone is set as the Playback device by default.

SAFETY AND MAINTENANCE
SAFETY GUIDELINES
In order to achieve maximum safety while using your Razer Seiren V2 Pro, we
suggest that you adopt the following guidelines:
Should you have trouble operating the device properly and troubleshooting does
not work, unplug the device and contact the Razer hotline or go to for
assistance.
Do not take apart the device and do not attempt to operate it under abnormal
current loads. Doing so will void your warranty.
When connecting external devices, carefully plan how the wires will be placed.
Protect any connected cables from being walked on or pinched, particularly at
plugs, convenience receptacles, or the point where they exit from.
When unplugging any connected devices and/or cables, always pull on its plug
or connector. Don’t forcefully tug on its cord.
Keep the device away from liquid, humidity or moisture. Operate the device
only within the specific temperature range of 0°C (32°F) to 40°C (104°F).
Should the temperature exceed this range, unplug and/or switch off the device
in order to let the temperature stabilize to an optimal level.
Listening to excessively loud volumes over extended periods of time can damage
your hearing.
Furthermore, legislation of certain countries permits a maximum sound level of
86db to affect your hearing for 8 hours a day. We therefore recommend that you
reduce the volume to a comfortable level when listening for prolonged periods
of time. Please, take good care of your hearing.
MAINTENANCE AND USE
The Razer Seiren V2 Pro requires minimum maintenance to keep it in optimum
condition. Once a month we recommend you unplug all connected cables and clean
it using a soft cloth or cotton swab to prevent dirt buildup. Do not use soap
or harsh cleaning agents.
