WIRELESS TRANSMITTER SONAB CTX
FCC ID: XCO-HSD81D82???
IC: 7756A-HSD81D82???
This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC
Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This
equipment generates uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a
particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined
by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following
measures:
—Reorient or relocate the receiving antenna.
—Increase the separation between the equipment and receiver.
—Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
—Consult the dealer or an experienced radio/TV technician for help.
To satisfy FCC RF exposure requirements, a separation distance of 20 cm or more should be maintained between this device and
persons during device operation. To ensure compliance, operations at closer than this distance is not recommended. The antenna
used for this transmitter must not be co-located in conjunction with any other antenna or transmitter.
This device complies with Part 15 of the FC C Rules. Operation is subject to the following two conditions: (1) this device may
not cause harmful interference, and (2) this device must accept any interference received, including interference that may
cause undesired operation.
Pour satisfaire aux exigences de la FCC d’exposition aux radiofréquences, une distance de séparation de 20 cm ou plus doit être
maintenue entre cet appareil et des personnes lors de fonctionnement du dispositif. Pour assurer la conformité des opérations
au plus près que cette distance n’est pas recommandée. L’antenne utilisée pour ce transmetteur ne doit pas être co-localisés en
conjonction avec toute autre antenne ou transmetteur.
Cet appareil est conforme à la Partie 15 des règlements de la FCC. L’opération est soumise aux deux conditions suivantes: (1)
cet appareil ne peut causer d’interférences nuisibles, et (2) cet appareil doit accepter toute interférence reçue, y compris les
interférences qui peuvent provoquer un fonctionnement indésirable.
Under Industry Canada regulations, this radio transmitter may only operate using an antenna of a type and maximum (or lesser)
gain approved for the transmitter by Industry Canada. To reduce potential radio interference to other users, the antenna type and
its gain should be so chosen that the equivalent isotropically radiated power (e.i.r.p.) is not more than that necessary for successful communication.
Conformément à la réglementation d’Industrie Canada, le présent émetteur radio peut
fonctionner avec une antenne d’un type et d’un gain maximal (ou inférieur) approuvé pour l’émetteur par Industrie Canada. Dans
le but de réduire les risques de brouillage radioélectrique à l’intention des autres utilisateurs, il faut choisir le type d’antenne et
son gain de sorte que la puissance isotrope rayonnée équivalente (p.i.r.e.) ne dépasse pas l’intensité nécessaire à l’établissement
d’une communication satisfaisante.
INSTALLATION
1. Place CTX high, preferably at same level as speakers.
2. If CTX is placed far from sound source, and the USB cable needs to be longer than 5m,
active USB cable must be used.
3. Place CTX freely and visible, not in closed compartments.
Avoid placing near or with blocking metal materials around of CTX.
4. Use the included wall bracket for easy placement on wall.
5. Secure CTX when placing. Do not let CTX hang with attached cables as only support.
6. When installing, place CTX as central as possible in the audio system where the wireless
speakers are placed. CTX transmits equally all around it.
WHE N INSTALLING, ALWAYS OBSERVE TH E NATIONAL INSTALLATION AND ACCIDENT PREV ENTION REGU LATIONS.

1. Mini USB in
COMPUTER: Connect directly to free USB port on your Mac/PC.
Note: Choose “SONAB” as sound output in Sound settings in system setting of the computer.
If “Line in” is used, the CTX needs to be powered with a separate power supply (Sold separately)
2. Line in
Connect any other analogue source with 3,5mm cable. Any analogue source with either 3,5mm
or stereo RCA output can be connected. The CTX must be connected to a USB power supply
through the mini USB port (sold separately) when the line in is used.

3. LED wireless indicator
Blue for wireless connection, Red for no connection (and Standby).
4. Channel
Set to channel 1, 2 or 3. (Whole system must use same channel as CTX transmitter.)

5. ID code
On each Channel(1-2-3), there is 10 different ID codes. Set whole system with same ID code.

The lightning flash with arrowhead symbol, within an
equilateral triangle, is intended to alert the user to the
presence of uninsulated “dangerous voltage” within the
product’s enclosure that may be of sufficient magnitude
to constitute a risk of electric shock to persons.
The exclamation point within an equilateral triangle is
intended to alert the user to the presence of important
operating and maintenance (servicing) instructions in the
literature accompanying the appliance.
WARNING:
TO REDUCE THE RISK OF FIRE OR ELECTRIC
SHOCK, DO NOT EXPOSE THIS APPARATUS TO
RAIN OR MOISTURE.
CAUTION:
TO REDUCE THE RISK OF ELECTRIC SHOCK,
DO NOT REMOVE COVER (OR BACK).
NO USER-SERVICEABLE PARTS INSIDE.
REFER SERVICING TO QUALIFIED
SERVICE PERSONNEL.
IMPORTANT SAFETY INSTRUCTIONS
1. Read these instructions.
2. Keep these instructions.
3. Heed all warnings.
