introduction
Congratulations on the purchase of your new FrontRow Tempo™active learning system!
You may have heard the term ‘sound field’ used to describe technology that improves
classroom acoustics. Your FrontRow system fits under this category, but we call it an ‘active
learning system’ because it’s about so much more than just sound.
Active learning systems can help engage students, improve attentiveness to the teacher,
build learning success, reduce the achievement gap, foster control and orderliness, improve
test scores, and reduce vocal strain and fatigue for teachers. Numerous studies show that
classrooms using active learning enjoy better student comprehension, increased student
participation, better grades and fewer behavioral referrals.
Read this manual carefully to become familiar with your product and to get the most out of
its many features and options.

Before you set up your system, take a good look around your room. Where are the outlets
located? Where are the computers and other electronic equipment? Where can you put your
receiver so it's easy for you to reach, but out of the way of students and main traffic areas?
Though each classroom is different, there are some general guidelines for both receiver and
speaker placement:
The receiver — should be in the front of the classroom at teacher's eye level when standing,
close to a wall outlet.
4 Compact wall speakers — should be mounted as high as possible and angled down
toward the listeners' ears. Place them around the room so there is even coverage in the listening
area (where the students are seated). Use as many as needed — four is recommended.*
4 Distributed ceiling speakers — space them evenly above the students’ seating area.
A minimum ceiling height of 10 feet is necessary, and 12 feet is even better. Use as many
as needed — a minimum of four is recommended.*
Single Cluster ceiling speaker — should be centered directly over the students’ seating
area. A minimum ceiling height of 12 feet is recommended, and 14 feet is even better.
* For optimal speaker placement, download Sound field Wizard software from our website at www.phonicear.com.

system guidelines
To help ensure that you get the most out of your new active learning system, we have put
together the following list of suggested guidelines:
Speak at a normal level — the system is projecting your voice for you.
Periodically check the volume and OptiVoice settings – these are often set and
then forgotten, but if accidentally changed, will affect how your system sounds.
Minimize the effects of feedback – avoid walking too closely to the speakers while
using the transmitter and microphone.
Place receiver in an open location – do not place the receiver in, or close to a metal
cabinet or enclosure. FM signals are effected by metallic objects and the receiver requires
proper cooling and ventilation.
Attach antenna – the receiver will not operate without the FM antenna.
Turn unit off while not in use – turning the unit off when not in use saves energy and
still allows the receiver to recharge the 330T/340T transmitter batteries when connected to
the rear of the receiver.

ommended setting for average noise levels.

high: Use in high noise levels. Helps to ensure top comprehension during critical tasks
such as test-taking or hearing impaired instruction.
NOTE: With each increase in level, there is an increase of approximately 3dB in gain
(volume). This may require a decrease in the receiver volume setting to avoid potential
microphone/speaker feedback.
OptiVoice is a 3-position switch that automatically adjusts the sound quality of the primary
speaker’s voice. It allows teachers to shape the sound of their voice and helps to ensure maxium
speech clarity in low, medium and high noise levels.
low: Use in low-noise situations and for most
natural voice quality.
medium: Best setting for average classrooms
where low-medium noise levels are present.

Follow steps or below to set FM volume to
proper level. Two people are needed to properly set the
volume level. It is difficult to hear your own voice and
make adjustments to it.
setting FM volume

1
With a sound level meter - Take a level reading in the “A” setting in the center of the room
during normal classroom activity, and another reading of the teacher's amplified voice (with-
out the class activity). The level of the teacher's voice should be set between 10-15 decibels
above room noise level.
Without a sound level meter - First, ask someone to help you set the volume to a com-
fortable listening level. As your listener, they should also be the person making adjustments to
the volume setting. The speaker should begin talking into the microphone at their normal
speaking level while the listener determines the appropriate volume setting. The recommended
volume setting is achieved when the sound from the loudspeakers and the speaker’s voice are
the same level. If the speaker can hear their own voice through the loudspeakers, the volume
setting is too high.
NOTE: The average volume setting is between 4–5, but
may change depending on room acoustics and noise level.
