I’ve heard that there are limitations with channels
with using fm soundfield systems ‒ does this
mean that you could only have a few Phonak
systems in a school?
In most situations you won't find any
limitations on the number of Roger
Dynamic SoundField systems you can
install. However, there are limits if you are
using them in conjunction with personal
fm (MLxi) receivers.
Some of my students use Phonak ZoomLink+ and
MLxi Dynamic FM systems ‒ can I use these with
the Phonak Dynamic SoundField?
Yes, you set the MLxi receivers to the fm channel of the
Roger inspiro used with the SoundField system and
listen directly to the inspiro fm instead of the
ZoomLink+.
Note ‒ you would require the Roger inspiro
to have FM turned on.
I’ve got students in my class that use non-Phonak
radio aid systems (such as the fmGenie) ‒ can
these be used with the Phonak SoundField?
Possibly. You can use any fm Radio Aid receiver on the
same frequency used by the Roger inspiro SF+FM
transmitter, however some users may hear a buzzing
noise. As rebroadcasting is not
possible with the Phonak
SoundField, if you experience
problems or want to ensure full
compatibility, we recommend
purchasing a system such as the
IR Swift or IR Classmate.
Can I use a SmartLink+ or ZoomLink+ transmitter
with the Phonak Roger SoundField in a
MultiTalker Network rather than a DynaMic?
No, the MultiTalker Network and the Dynamic Soundfield
system only works with Roger inspiro and Roger
DynaMic transmitters.
Can I update the software for the
Phonak SoundField and inspiro
transmitter in the same way as you can
when using the inspiro as a radio aid
only?
Yes, you simply connect the DigiMaster SoundField unit
to your computer using the supplied USB lead.
I’m worried that one Phonak
DigiMaster 5000 speaker won’t be
enough to cover the whole of my
classroom. Can you add in another
speaker?
No, the Phonak DigiMaster 5000 only uses
one speaker unit per system. If you have
a particularly large or unusually shaped
classroom a Phonak DigiMaster 7000 would
be more appropriate. This is a more
powerful system and comes with two
speakers which can be placed around the
room to ensure good sound coverage.

Classroom soundfield FAQs
Positioning of single speaker systems verses multi-speaker systems
Generally, an IR Swift is ideally suited to classrooms where the teacher is primarily based at one end of the
room ‒ the IR Swift is mounted at the opposite end, approximately 1.5m off the ground, thereby creating an
effective soundfield from one speaker. Phonak recommend their SoundField is best situated in one corner at
the front of the classroom with the wall bracket mounted 1.4m from the ground.
A single speaker system is a very effective, good value solution , however a multi-speaker system such as the
IR Classmate is more appropriate for some situations, such as large or unusually shaped classrooms.
Multi-Speaker Systems: room size versus number of speakers
For an IR Classmate, as a rough rule of thumb, four speakers are suitable for a classroom up to
10 x 8 metres. Six speakers would provide coverage up to 14 x 8 metres or where the classroom is not an
unobstructed rectangle.
