Your new Simeon 966 soundfield FM system is easy to set up and use in any classroom. The sys-
tem can be used with a variety of microphone and speaker options and can be easily interfaced
with other audio and FM equipment. The system includes the following components:
* FM Transmitter 8LT with high capacity NiMH batteries
* Directional boom microphone 617 (or optional alternate microphone model)
* FM Transmitter/microphone 801TS with high capacity NiMH batteries
* Stretchable transmitter hip pack
* Soundfield FM receiver 966R with built-in amplifier
* Transmitter charging stand HDC-202 with dual charging pockets
Simeon 966 speaker options:
Single Omnipanel DML flat panel speaker with Speakon cable OR Four SP-966 mini wall-mount
speakers with regular speaker wire.
INSTALLATION WITH OMNIPANEL SPEAKER
Carefully unpack the soundfield system. The Omnipanel can be wall mounted with the included
hardware or may be or tripod mounted using an optional lightweight aluminum floor stand. For
wall mounting, choose a suitable location to mount the Omnipanel speaker on the classroom wall
and check that it is sufficiently close to an AC power outlet. Choose a location to mount the
Omnipanel above head level if possible. The front, back or side walls of the classroom are all suit-
able locations.
There are two methods of wall mounting the Omnipanel speaker. It can be mounted flush with the
wall 'picture style' using just two mounting screws, or it can be mounted on a special adjustable
swivel bracket. To flush mount, fasten the Omnipanel to the wall using the two screws and wall
anchors supplied. The screws must be positioned exactly 43cm apart to ensure an accurate fit.
The Omnipanel has two keyhole-shaped openings on the rear panel to accommodate these
screws. Adjust the tightness of the screws to ensure the Omnipanel frame is held firmly when
mounted on the wall (a loosely mounted Omnipanel frame may vibrate against the wall and make
audible noise). The advantage of mounting the Omnipanel flush with the wall is that it will be less
conspicuous, but it must be attached to the wall securely to avoid vibration, and is best suited to
speaker placements away from the corners of the classroom
The preferred method of mounting the Omnipanel speaker is with the special wall-mount bracket
(see below). This allows more flexibility to orient the speaker and allows it to be removed very
easily for use in another location. It also allows the Omnipanel to be mounted anywhere in the
room, even in a corner, to the fullest acoustic advantage. The bracket should be attached secure-
ly to a solid wall surface using the included hardware.

INSTALLATION WITH FOUR SP-966 MINI SPEAKERS
Select suitable locations for the four SP-966 mini speakers around the classroom walls. Choose
locations above head level and evenly spaced across the room to ensure the most even distribu-
tion of the soundfield. Avoid placing the speakers in the room corners and directly facing and
opposing each other as this will cause phase cancellations and result in an uneven soundfield.
For best results all four speaker should be oriented in the same general direction.
Suggested classroom configuration for four SP-966 mini-speakers
To mount the mini speakers, remove the caps from the U-bracket and secure the U-bracket to the
wall using the hardware supplied. Attach speaker wire to each speaker, taking care to observe the
correct polarity (+ve and -ve connectors), and run all four speaker wires to a central location for
the 966R receiver and close to a power outlet.
SP-966 mini-speaker trim controls
A special feature of the Simeon 966 enables individual gain adjustment of each of the four SP-
966 mini-speakers. This allows for more focal or differential amplification in different areas of the
Position the SP-966 mini
speakers so that they are
all pointing in the same
general direction.
This will ensure that they
are reinforcing and not
opposing each other.
This configuration will
result in the most uniform

classroom. Note that individual mini-speaker gain adjustments are made using special trimmers
located on the underside of the 966R receiver unit. Differential speaker gain adjustments should
be made in consultation with your audiologist or sound professional.
SETTING UP THE 966R RECEIVER UNIT
The 966R receiver unit has two FM receiver modules, an integrated amplifier, and multiple inputs
and outputs to connect to other audio and FM devices. It is the base station of the entire sound-
field system.
Receiver 966R - Front panel
The receiver unit itself requires no special installation, but should be placed in a suitable safe
location, such as shelving, well within reach of the speaker cables and sufficiently close to a
classroom power outlet. There are just a few short steps required to ready the 966R receiver for
use.
First, make the speaker connection. The Omnipanel speaker is connected with a single conven-
ient Speakon connector cable, which is inserted into the rear panel. Twist the Speakon plug to
lock; to release again, pull the release button on the plug. If using the SP-966 mini speakers,
these must be connected via regular speaker wire to the screw-terminals on the rear panel of the
receiver. Up to four mini-speakers can be connected to the 966R receiver. Be sure to observe the
correct polarity (+ve and -ve connectors) when connecting the mini speakers.
Next, connect the two antennae to the connectors on the rear panel. Adjust each antenna to the
vertical position for best reception. Connect the power adapter to the DC IN connector on the rear
panel of the 966R receiver. Be sure to use only the recommended and approved power adapter

(12 - 16v DC; 1.6 amps). Note that the transmitter charging cradle model HDC-202 is also sup-
plied with its own power adapter, but the charging cradle can also be powered directly from the
DC OUT socket of the receiver model 966R using the short (15cm) DC cable supplied. This is a
convenience in classrooms with few available power outlets.
Receiver 966R - Rear panel
PREPARING THE SYSTEM FOR USE
Check that the transmitters and receiver are set to matching channels, and that the selected
channel frequencies do not conflict with other FM equipment at your school. It is important that a
separate channel is selected for each transmitter. Two transmitters cannot share the same chan-
nel without interference. Note that the Simeon 966 system is available in at least two UHF fre-
quency bands (744 - 752 MHz and 794 - 806 MHz), each with 16 FM channels. If using six or
more systems in one location, consider use the second frequency band as there are performance
considerations when multiple channels are used in very close proximity. Contact your represen-
tative if you have any difficult selecting an FM channel for your system.
FM Transmitter 8LT
Open the transmitter battery compartments as shown and insert the NiMH rechargeable batteries
supplied, taking care to observe correct battery polarity. For best performance, use only the rec-
ommended NiMH (nickel metal-hydride) rechargeable size AA transmitter batteries.
Never use disposable (alkaline) batteries in combination with the charging system.
Place the transmitters into the two charging pockets of the HDC-202 charging cradle and charge
fully before using (see Battery Care and Charging section below). When transmitter charging is

complete (3 - 6 hours charge time) the charging cradle will show a green light (Ready) below each
charging pocket.
Place the fully charged transmitter model 8LT into the hippack and adjust for comfort. Plug the
microphone into the transmitter mic jack. If using the standard Simeon 617 boom (headset) micro-
phone, place the frame over the ears and adjust the boom arm to position the mic capsule to point
to the corner of your mouth. It is not necessary to place the microphone in front of your lips and
doing so may diminish the sound quality. It is usually necessary to adjust the microphone frame
by bending so that it rests lightly over the ears, avoiding any other contact or pressure points
against the head. It is important to adjust the microphone frame in this way to ensure a comfort-
able fit. The Simeon 617 boom mic is supplied with a Velcro headband to keep the microphone
secure during vigorous activities (e.g. Phys Ed.). This band may be removed for regular class-
room use.

FM Transmitter/microphone 801TS

FM Transmitter/microphone 801TS
After charging the transmitter/microphone model 801TS, remove from the charging cradle and
turn ON to use. The capsule of the 801TS transmitter/microphone is highly directional - point the
microphone directly towards the mouth to ensure the best performance. If you need to change the
channel of transmitter/microphone 801TS, there is a small key located inside the battery housing
that will fit the channel selector (please see image on next page).
Setting gain level
Check the volume positions before turning your soundfield system on! The Simeon 966R receiv-
er is equipped with two independent volume controls - one for each FM channel. In addition,
transmitter 8LT is equipped with a volume control, which is best set above ½ full-on to allow for
fine gain adjustment. Note that the transmitter/microphone 801TS has no volume control, so the
gain for this channel must be set using the 966R receiver volume controls.
To set the volume (gain) level, position the microphone correctly, turn on, and gradually increase
the volume until your amplified voice is clearly audible but not loud. Avoid excessive amplification
- soundfield FM will make speech clearly audible throughout your classroom at a comfortable lis-
tening level.
Special feature (for SP-966 mini-speakers only)
Differential gain adjustments to each of the four SP-966 mini-speaker gain adjustments may be
made using special trimmers located on the underside of the 966R receiver unit. Differential
speaker gain adjustments should be made in consultation with your audiologist or sound profes-
sional.
BATTERY CARE AND CHARGING
For best performance, use only the recommended NiMH (nickel metal-hydride) rechargeable size
AA transmitter batteries. These batteries are not susceptible to memory and can be recharged
after only partial use.
Never use disposable (alkaline) batteries in combination with the charging system.
Disposable batteries are not suitable for recharging and attempting to recharge them may result
in damage to your equipment.
Charging cradle HDC-202
The charging cradle model HDC-202 has two charging pockets, either of which will charge trans-
mitter model 8LT or transmitter/microphone model 801TS. It is good practice to charge the trans-
mitters at the end of each day. Remember to turn both transmitters OFF before placing them into
the charging pockets. The charger indicator lights show charging progress: charging (amber

LED); ready (green LED). Charge time is typically between 3 and 6 hours, depending on battery
condition. Prolonged transmitter charging is not a problem - the charging cradle will automatical-
ly prevent overcharging of the transmitter batteries (intelligent charging).
The HDC-202 charging cradle is supplied with its own AC/DC power adapter. For convenience,
the charging cradle may also be connected directly to the DC OUT socket of the 966R receiver,
thus allowing operation of both devices from a single power source. A short (15cm) DC connec-
tor cord is supplied with receiver 966R for this purpose. Note that the HDC-202 charging cradle
will always operate normally whether the 966R receiver power is turned ON or OFF.
If a transmitter has been left turned ON until the batteries are completely discharged, the charg-
er sensor may indicate 'Ready' after only a few minutes of charging time. If this happens it may
be necessary to give two or more 'priming' charges (at least 30 minutes charge time), followed by
a full 6 hour charge cycle to restore a full battery charge.
Never use disposable (alkaline) batteries in combination with the charging system.
PERSONAL FM SYSTEMS
The Simeon 966R receiver is equipped with two separate auxilliary outputs that may be connect-
ed to personal FM transmitters to accommodate students with various types of personal FM sys-
tems. These outputs are located on the front and rear panels and are labeled AUX OUT. Check
that you have the correct connection cable and have the interface checked by an audiologist to
verify the signal quality. Note that the AUX OUT gain level is controlled via the two 966R receiv-
er volume controls.
Other external connections
In addition to making connection to personal FM systems, the Simeon 966 can be interfaced with
most other audio devices, including classroom computers. There are two sets of RCA stereo input
connectors on the rear panel, and volume can be adjusted for these inputs independently of the
FM gain. It is also possible to connect a cabled pass-around microphone directly to the 966R
receiver via the MIC IN jack on the front panel.

USEFUL TIPS
Be sure that the two transmitters are set to separate channels and that matching channels are
selected on the Simeon 966R receiver
Adjust the Simeon 617 boom (headset) microphone for comfort. Bend the frame so that the micro-
phone is supported lightly by both ears with no pressure or contact points. Position the mic cap-
sule so that it points toward the corner or the mouth.
Wear the 8LT transmitter in the stretchable hippack. The hippack is more secure than the belt clip
and will protect the transmitter and delicate microphone from drop damage.
Keep the volume of the 8LT transmitter higher than the receiver volume setting. This allows fine
volume adjustment and helps avoid acoustic feedback.
Avoid excessive amplification - soundfield FM will make speech clearly audible throughout your
classroom at a comfortable listening level.
Avoid approaching very close to the Omnipanel or mini-speakers with the microphone turned on
- this may cause a loud squeal (acoustic feedback).
Do not adjust the tone control settings unless this has been recommended by an audiologist.
Excessive bass adjustment may degrade speech intelligibility.
For convenience, keep the HDC-202 charging stand plugged into DC OUT on the rear panel of
the 966R receiver. This allows operation from a single power source.
Use only the recommended batteries and power adapters.
Never use disposable (alkaline) batteries in combination with the charging system.
MICROPHONE CARE
The microphone is the most delicate component of your soundfield system. Protect the micro-
phone cord and plug from strain and excessive flexing. Clean the pin of the microphone plug peri-
odically with an approved electronics contact cleaner to maintain noise-free performance.
Replace damaged or missing foam windscreens and protect the microphone capsule from mois-
ture.
Simeon 617 boom (headset) microphone: this model has a unidirectional pick-up pattern. The tip
of the mic capsule must be pointed towards the corner of the mouth for proper performance.

TROUBLESHOOTING
No sound
Check volume settings (transmitter and receiver). Check that there is power to the receiver and
that it is turned ON. Ensure that the speaker cable is connected securely. Check that the trans-
mitters are set to the ON position (not STANDBY). Verify that the 966R receiver is receiving FM
signal (indicated by green LED on receiver). Check or replace transmitter microphone.
No FM signal
Check that the selected transmitter channels are matched with the receiver channels and that
they are on the same frequency band. Check or replace transmitter batteries. Check transmitter
switch is set to ON position (not STANDBY) and that there is sufficient battery power (indicated
by green LED on transmitter).
Dead batteries
First, make sure that only the recommended NiMH (nickel metal-hydride) rechargeable size AA
transmitter batteries are in use. Check that the batteries are making good contact inside the
transmitter battery housing. Make sure that the transmitters are turned OFF during charging, and
that the charging cradle is receiving power via the correct power adapter model.
If the transmitter batteries are completely drained and are failing to charge, give two or more
'priming' charges (at least 30 minutes charge time), followed by a full 6 hour charge cycle to
restore a full battery charge.
Never use disposable (alkaline) batteries in combination with the charging system.
Weak sound
Check volume settings (transmitter and receiver). Adjust microphone position. Check or replace
microphone. Check that the correct power adapter is connected to the receiver.

Noise or Distortion
Check that the two transmitters are set to different FM channels -transmitters cannot share the
same channel without interference. Check for possible sources of radio interference (e.g. wire-
less LAN, other FM systems) and select a different FM channel pair while ensuring that the trans-
mitters are kept on separate channels. Check the microphone and the integrity of microphone
cord and plug. Clean mic plug with a recommended contact cleaner.
Acoustic Feedback
Check and adjust volume settings. Ensure that the microphone is positioned correctly. Avoid
approaching very close to the Omnipanel or mini-speakers with the microphone on.
Intermittency
Check microphone, mic cable and the plug connection with the transmitter. Replace microphone
if necessary. Check that both antennae are fitted to the rear panel of the 966R receiver, and that
the 8LT transmitter antenna is secure. Make sure that all cables are fitted securely.

Options de haut-parleurs du Simeon 966:
Un seul haut-parleur DML plat Omnipanel avec câble Speakon OU quatre haut-parleurs minia-
tures muraux SP-966 avec câble de haut-parleur régulier.
INSTALLATION AVEC HAUT-PARLEUR OMNIPANEL
Déballer avec soin le système champ libre. L'Omnipanel peut être fixé au mur à l'aide du matériel
inclus ou installé sur un trépied au moyen d'un support de plancher léger en aluminium. Pour une
installation murale, choisir un emplacement approprié pour le haut-parleur Omnipanel sur le mur
de la salle de classe et s'assurer qu'il se trouve suffisamment près d'une prise de courant. Si
possible, l'Omnipanel doit être fixé au mur à un niveau plus élevé que la tête. Les murs situés à
l'avant et à l'arrière de la classe et les murs latéraux sont tous appropriés.
Deux méthodes permettent de fixer le haut-parleur Omnipanel au mur : affleurant au mur, comme
un cadre, avec deux vis de montage, ou bien à l'aide d'un support pivotant spécial réglable. Pour
un montage à affleurement, fixer l'Omnipanel au mur à l'aide des deux vis et des dispositifs d'an-
crage fournis. Les vis doivent être placées à exactement 43 cm de distance pour s'assurer d'une
fixation précise et solide. L'Omnipanel est doté de deux points de fixation à l'arrière où ces vis
doivent être logées. Ajuster le serrage des vis pour s'assurer que le cadre de l'Omnipanel soit
fixé solidement au mur (un cadre mal fixé peut vibrer contre le mur et ces vibrations peuvent être
audibles). L'avantage d'un montage mural à affleurement est que l'Omnipanel sera moins visi-
ble, mais il doit être fixé solidement au mur pour éviter les vibrations, et il est préférable de plac-
er les haut-parleurs loin des coins de la classe.
Cependant, la méthode préférable pour fixer les haut-parleurs Omnipanel est à l'aide du support
mural spécial (voir ci-après). Cette méthode offre plus de flexibilité pour l'orientation des haut-
parleurs et permet de les enlever très facilement pour les utiliser à un autre endroit. Elle permet
également de fixer l'Omnipanel n'importe où dans la pièce, même dans un coin, et offre ainsi des
avantages acoustiques complets. Le support doit être fixé solidement sur le mur à l'aide du
matériel fourni.

INSTALLATION AVEC QUATRE HAUT-PARLEURS MINIATURES SP-966
Choisir des emplacements appropriés pour les quatre haut-parleurs miniatures SP-966 sur les
murs de la classe. Opter pour des emplacements au-dessus du niveau de la tête et à distance
égale dans la pièce pour s'assurer de la distribution la plus uniforme possible du champ libre.
Éviter de placer les haut-parleurs dans les coins de la pièce et de les pointer directement l'un
vers l'autre car cela entraînera des annulations de phase et un champ libre non uniforme.
Pour de meilleurs résultats, les quatre haut-parleurs doivent être orientés dans la même direction
générale.
Suggestion de configuration avec quatre mini-haut-parleurs SP-966
Pour fixer les haut-parleurs miniatures, retirer les capuchons du support en U et le fixer solide-
ment au mur au moyen du matériel fourni. Brancher les câbles des haut-parleurs à chaque haut-
parleur en veillant à respecter la polarité (connecteurs + et -) et relier les quatre câbles de haut-
parleur à un emplacement central pour le récepteur 966R et à proximité d'une prise de courant.
Placer les haut-parleurs

Commandes de réglage des haut-parleurs miniatures SP-966
Un dispositif spécial du Simeon 966 permet un réglage individuel du gain pour chacun des qua-
tre haut-parleurs miniatures SP-966 et une amplification plus focale ou différentielle à différent
endroits dans la classe. Noter que le réglage individuel du gain des haut-parleurs miniatures se
fait au moyen de dispositifs spéciaux situés sur la face inférieure du récepteur 966R. Le réglage
différentiel du gain doit être effectué en consultation avec votre audiologiste ou professionnel du
son.
PRÉPARATION DU BLOC RÉCEPTEUR 966R
Le bloc récepteur 966R comporte deux modules récepteurs MF, un amplificateur intégré, et de
multiples entrées et sorties pour un branchement à d'autres appareils audio et MF. Il agit à titre
de station de base pour tout le système champ libre.
Récepteur 966R - Panneau avant
Le récepteur n'exige aucune installation particulière mais doit être placé à un endroit sécuritaire
approprié, par exemple, une étagère, à portée des câbles de haut-parleurs et suffisamment près
d'une prise de courant. La préparation du récepteur 966R se fait en quelques étapes seulement.
D'abord, brancher le haut-parleur. Le haut-parleur Omnipanel se branche à l'aide d'un seul câble
Speakon pratique qu'on insère dans le panneau arrière. Faire pivoter le connecteur Speakon pour
le verrouiller; pour le déverrouiller, appuyer sur le bouton situé sur le connecteur. Si vous utilisez
des haut-parleurs miniatures SP-966, ceux-ci doivent être branchés aux bornes à vis situées sur
le panneau arrière du récepteur à l'aide des câbles de haut-parleurs réguliers. Jusqu'à quatre
haut-parleurs miniatures peuvent être branchés au récepteur 966R. Veiller à respecter la polarité
(connecteurs + et -) lors du branchement des haut-parleurs miniatures.

Ensuite, brancher les deux antennes aux connecteurs du panneau arrière. Ajuster chaque
antenne en position verticale pour une meilleure réception. Brancher l'adaptateur de courant au
connecteur DC IN situé sur le panneau arrière du récepteur 966R. Veiller à utiliser un adaptateur
de courant recommandé et approuvé (12 - 16v DC; 1,6 A). Noter que l'embase avec fentes de
recharge de l'émetteur HDC-202 est également dotée de son propre adaptateur de courant, mais
qu'elle peut aussi être alimentée directement à partir de la sortie DC OUT du récepteur 966R à
l'aide du petit câble c.c. (15cm) fourni. Ceci est très pratique dans les salles de classe avec peu
de prises de courant
Récepteur 966R - Panneau arrière
PRÉPARATION DU SYSTÈME
Vérifier que les émetteurs et le récepteur sont réglés sur le même canal et que les fréquences
sélectionnées n'entrent pas en conflit avec d'autre équipement MF de votre école. Il importe de
sélectionner un canal différent pour chaque émetteur. En effet, deux émetteurs ne peuvent
partager le même canal sans créer d'interférence. Prendre note que le système Simeon 966 est
offert avec au moins deux bandes de fréquences UHF (744 à 752 MHz et 794 à 806 MHz), cha-
cune comptant 16 canaux MF. Si vous utilisez six systèmes ou plus au même endroit, il faudrait
songer à utiliser la deuxième bande de fréquence pour assurer une bonne performance. Si vous
éprouvez de la difficulté avec la sélection d'un canal MF pour votre système, contacter votre
représentant.
ÉMETTEUR MF 8LT
Ouvrir le compartiment à piles de l'émetteur tel qu'illustré et insérer les piles NiMH rechargeables

phone serre-tête standard Simeon 617, placer la base du microphone au-dessus des oreilles et
ajuster le bras du microphone serre-tête de manière à ce que la capsule microphonique pointe
vers le coin de votre bouche Il n'est pas nécessaire de placer le microphone devant vos lèvres
car cela pourrait diminuer la qualité sonore. Il est habituellement nécessaire d'ajuster le cadre du
microphone en l'incurvant afin qu'il se retrouve juste au-dessus des oreilles et en évitant tout
point de contact ou de pression sur la tête. Il est important d'ajuster le cadre du microphone de
manière confortable. Le microphone Simeon 617 est doté d'un serre-tête en velcro qui garde le
microphone en place pendant les activités intenses (p.ex.éducation physique). Ce serre-tête
peut être retiré pour utilisation dans une salle de classe régulière.
