Description
The IMM-2320V2 is a combination of a basic audio mixer for stereo music sources and two micro-
phones with a media player including FM tuner and IR remote control. It perfectly serves applications
where foreground or background music is mixed with vocal announcements, as it frequently occurs
in fitness and hospitality applications. Specifically in fitness music applications, the IR remote control
and the automatic music level reduction when the microphone is spoken into, greatly facilitate
efficient instructor work. A Bluetooth receiver feature is available optionally (version IMM-2320V2B).
Maintenance and warranty
While we have chosen the best components to make this product as rugged and reliable as possible,
some parts in audio products (potentiometers, faders, switches) are subject to wear which is a
matter of operation cycles, and not of time. While providing a full time-based warranty according to
the country’s of purchase requirements on the function of the electronic circuitry, we hence have to
limit the warranty on such electro-mechanical parts to 90 days from the date of purchase.
Kindly note that any warranty is void if the unit has been modified ar attempted to be reparied by inap-
propriate means or a non-qualified service center.
