Max EX is unique in its expansion capabilities—you expand it by connecting additional phone units, not just microphones. This creates an even distribution of microphones, loudspeakers and controls for better sound quality and user access. No matter where participants are seated, conversations
are natural and effortless. Up to four Max EX phones can be connected to accommodate different room sizes.

Max EX features advanced audio technology typically found only in high-end installed systems—with Gentner® Distributed Echo Cancellation®, noise cancellation and advanced microphone
activation processes—so you can count on clear, highly intelligible audio for effective, interactive conferences.

Setting up the Max EX conferencing phone is extremely easy and requires only three connections: power, telephone line and base unit. The familiar keypad design ensures users will be
comfortable using the phone, which reduces the need for training and support.

Expandable - Max EX is ideal for any size conference room and provides complete microphone and loudspeaker coverage and easy access to controls.

Superior Audio - The clear, full sound of the Max EX facilitates more natural interaction between participants.

One-Touch Conferencing - Press a button and access a conferencing-services operator
who can connect an unlimited number of participants.

Easy to Use - Intuitive, user-friendly controls are simple to operate.

The Max EX is ideal for customers who require high-quality audio, ease of use and flexibility. Already perfect for small meeting rooms, Max EX phones can be combined or separated to match the size of virtually any room in your organization. Whether you conduct your meetings from a
large boardroom (three phones), a training room (four phones) or a conference room (two phones), you can easily create the optimal conferencing system with Max EX.

–Gentner® Distributed Echo Cancellation® effectively eliminates echo

The Max EX expands by connecting additional phones, not just expansion microphones. This creates a better distribution of loudspeakers and microphones so all participants can
hear and be heard clearly.
