introduction
Congratulations on the purchase of your new 230R sound field receiver! With proper care and
use it will become one of your most valuable classroom tools for many years. Students will
be able to consistently and easily understand what the teacher is saying, regardless of
his/her location in the classroom. Teachers can now speak all day in their normal voice
without having to raise their voice to get their students’ attention.
Numerous studies show that classrooms using sound field enjoy better student comprehen-
sion, increased student participation, better grades and fewer behavioral referrals.
Read this manual carefully to become familiar with your receiver 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.
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.*
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.*
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 sound field 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 transmitter batteries when connected to the
rear of the receiver.

low: Recommended for use in low-noise situations and for most natural voice quality.
medium: Recommended for everyday use. Best setting for average classrooms where low-
medium noise levels are present.
high: Recommended for 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 you to decrease your volume setting to avoid potential micro-
phone/speaker feedback.
OptiVoice is a 3-position switch that automati-
cally adjusts the sound quality of the primary
speaker’s voice. It allows teachers to shape the
sound of their voice and helps to ensure maxi-
um speech clarity in low, medium and high
noise levels.

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

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
(without 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 other than yourself (if you are the
teacher) to listen to the amplified voice and make volume adjustments. An ideal volume level
is achieved when the listener can hear the amplified voice at a comfortable level and the vol-
ume level from the speaker and teacher’s mouth is comparable. If you can hear yourself
through the loudspeakers, the volume setting is too high and should be decreased
NOTE: The average volume setting is
between 4–5, but may change depending
on room acoustics and noise level.
