OVERVIEW
Congratulations on your purchase of the Wirez LCTS-2. This is a high quality level
converter with signal sensing. It is capable of being used in many configurations
with both original equipment (factory installed) and aftermarket products.
Features:
• Selectable RCA or Speaker Wire Input/Output Configuration
• Independent Left and Right Output Level Control
• Signal Sensing Remote Turn On Output
INSTALLATION NOTES
1. The LCTS-2 should be mounted in a location that is easily accessible for system
tuning.
2. Ground and fused power connections should be made directly to the head unit power
connection to prevent ground loops.
3. To provide maximum signal to noise ratio performance, the use of an oscilloscope
or distortion detection device like the SMD DD-1 should be used to properly set the
output level of the head unit, LCTS-2 and if applicable, the amplifier in your system.
4. A common ground wire is included on both the input and output RCA and speaker
wire harnesses of the LCTS-2. This wire is connected internally. In some applications,
you may need to connect this wire to the chassis of the source unit and/or the
amplifier for the LCTS-2 to work properly. The criteria that most commonly require the
use of this wire are:
LCTS-2 does not turn on when the radio is turned up
No audio produced by the LCTS-2
Engine noise and/or alternator whine in the audio system
Lack of bass / low Frequency music content
5. The LCTS-2 will not produce alternator whine. It may, as with all signal processors,
present a ground loop in the system that results in noise being introduced to the
system. This is not a failure of the product and can be addressed through proper
installation and the use of the common ground wire.
6. If you are not experienced with the installation of mobile electronic components,
the proper procedure to set system gain structure or do not fully understand these
instructions, Wirez strongly recommends that you seek the assistance of a trained
professional mobile electronics installer to complete the installation and tuning of your
mobile entertainment system.
7. Note: Many source units with Bluetooth Hands Free or Navigation only output audio
from these sources on the front speaker wire or RCA outputs. Please take this into
consideration when making your head unit connections.
POWER CONNECTION INSTRUCTIONS
Proper power connections are important to the reliable operation of the LCTS-2 or
any electronic component in your vehicle. Wirez recommends that all connections be
soldered where possible.
Yellow Wire: Fused Constant +12V source
Black Wire: Ground (same ground reference as the radio)
Blue Wire: Remote turn on output to aftermarket amplifier.
Grey/Grey Black: Right Speaker Positive / Negative Input / Output
White/White Black: Left Speaker Positive / Negative Input / Output
Red/White RCA: Right/Left RCA Input / Output
APPLICATION 1
The most common use of the LCTS-2 is to connect the speaker outputs of a radio to the
RCA inputs of an aftermarket amplifier.
1. Connect the power, ground and remote wires as described in the Power Connection
Instructions.
2. Connect the speaker wire plug to the Input jack. Set the Input switch to Wire.
3. Connect the RCA plug to the Output jack. Set the Output switch to RCA.

or a pair of Male-to-Male couplers.
7. Proceed to the Level Setting Instructions.
AFTERMARKET AMP
APPLICATION 2
Another common use of the LCTS-2 is to connect the RCA outputs of an aftermarket
source unit to the input of a factory installed amplifier. This is very common in vehicles
with premium sound systems.
1. Connect the power, ground and remote wires as described in the Power Connection
Instructions. Some aftermarket amplifiers and power antenna’s require a remote input.
Please check the wiring instructions for the specific vehicle you are working on, these are
often included with wire harness adapters.
2. Connect the RCA plug to the Input jack. Set the Input switch to RCA.
3. Connect the Speaker wire plug to the Output jack. Set the Output switch to Wire.
4. Connect the RCA inputs to the RCA output of your aftermarket head unit.
5. Connect the Grey and Grey/Black wires to the Right speaker input of the amplifier.
6. Connect the White and White/Black wires to the Left speaker input of the amplifier.
7. Proceed to the Level Setting Instructions.
Note: In some installations, you may required more signal gain / output voltage from the
LCTS-2 than it can provide. In that case, please use the Wirez LCDSS10-2 Line Driver.
FACTORY AMP
APPLICATION 3
Very similar to Application 2, the LCTS-2 can be used to connect the speaker outputs
of an aftermarket source unit to the input of a factory installed amplifier. This is common
where the preamp outputs of the aftermarket source unit are not adequate to achieve
maximum power from the factory amplifier.
1. Connect the power, ground and remote wires as described in the Power Connection
instructions. Some aftermarket amplifiers and power antenna’s require a remote input.
Please check the wiring instructions for the specific vehicle you are working on, these are
often included with wire harness adapters.
2. Connect the Speaker wire plug to the Input jack. Set the Input switch to Wire.
3. Connect the Speaker wire plug to the output jack. Set the Output switch to Wire.
4. Connect the Grey and Grey/Black input wires to the Right speaker output of the radio.
5. Connect the White and White/Black input wires to the Left speaker output of the radio.
6. Proceed to the Level Setting Instructions.
Note: In some installations, you may required more signal gain / output voltage from the
LCTS-2 than it can provide. In that case, please use the LCDSS10-2 Line Driver.
FACTORY AMP
APPLICATION 4
The LCTS-2 can be used to connect the subwoofer output of a factory subwoofer to the
to the RCA input of an aftermarket amplifier. As most subwoofer outputs use a single
mono channel we will connect both inputs to the LCTS-2.
1. Connect the power, ground and remote wires as described in the Power Connection
instructions.
2. Connect both the Grey and White wires to the Positive subwoofer output wire from the
factory amplifier, Set the Input switch to Wire.
3. Connect both the Grey/Black and White/Black wires to the Negative subwoofer output
wire from the factory amplifier.
4. Connect the RCA Outputs to the input of the amplifier using a short interconnect cable
or a pair of Male-to-Male couplers.
5. Proceed to the Level Setting Instructions.
Note: In some installations, you may required more signal gain / output voltage from the
LCTS-2 than it can provide. In that case, please use the LCDSS10-2 Line Driver.
AFTERMARKET AMP
FACTORY SUB AMP
LEVEL SETTING
Wirez strongly recommends the use of an oscilloscope or a level setting tool like the SMD
DD-1 to properly set the gains on any amplified system. This is the best way to ensure
maximum signal to noise performance from your system. You may also want to use the
oscilloscope, a voltmeter or a product like the SMD CC-1 to ensure the left and right
output of the amplifier is identical.
1. Turn the gain on your amplifier down all the way. Turn the Left and Right level controls
on the LCTS-2 down to ¼ of full. Insert a CD into the source unit and increase the output
level of the source unit until the signal distorts. Audio output may be very low.
2. Increase the Left and Right level control on the LCTS-2 until the output of the amplifier
starts to distort, the back them down 1/8 of a turn.
3. If the amp does not distort, turn up the gain/sensitivity control on the amplifier until it
distorts. The goal is to get full power out of the amplifier with the least possible amount of
gain increase.
4. Note: some amplifiers can not accept a high voltage input signal on the RCA inputs.
You may need to decrease the output of the LCTS-2 so as not to overdrive the input to
the amp. You may subsequently have to turn up the gain of the amplifier.
5. For maximum system performance, you should ensure that the output of the left and
right channel of your system is identical. This can be checked using the SMD CC-1, an
oscilloscope or a quality True RMS DMM and a test tone CD. It can be fine-tuned using
the Left or Right level control on the LCTS-2.
Note: In some installations, you may required more signal gain / output voltage from the
LCTS-2 than it can provide. In that case, please use the LCDSS10-2 Line Driver.

SURVOL
Félicitations pour votre achat du LCTS-2 de Wirez. Il s’agit d’un convertisseur de haute
qualité avec détection de signal. Il est capable d’être utilisé dans de nombreuses
configurations à la fois avec l’équipement d’origine (installé en usine) et produits après-
vente.
Caractéristiques:
• Configuration choix de sélection Entrée / Sortie RCA ou Fil Haut-Parleur
• Commande Niveau de sortie indépendante Gauche et Droit
• Détection de Signal pour Mise Sous Tension
REMARQUES D’INSTALLATION
1. Le LCTS-2 doit être installé dans un endroit qui est facilement accessible pour le
réglage du système.
2. Les raccordements électriques du courant et de la mise à la masse doivent être faits
directement à la connexion d’alimentation de l’unité de source pour éviter les retours
de masse.
3. Pour fournir une performance maximale rapport signal/bruit, l’utilisation d’un
oscilloscope ou d’un dispositif de détection de distorsion comme le SMD DD-1 devrait
être utilisé pour régler correctement le niveau de sortie de l’unité de source, du LCTS-
2 et le cas échéant, de l’amplificateur dans votre système.
4. Un fil de mise à la masse commun est inclus à la fois a l’entrée et la sortie RCA et
sur le harnais de fil haut-parleur du LCTS-2. Ce fil est connecté à l’intérieur. Dans
certaines applications, il peut être nécessaire de connecter ce fil au châssis de l’unité
source et/ou de l’amplificateur pour que le LCTS-2 fonctionne correctement. Les
raisons qui justifient le plus couramment l’utilisation de ce fil sont les suivantes:
Aucun son produit par le LCTS-2
Bruit de moteur et/ou d’alternateur dans le système audio
Manque de basses/contenu musical de basse fréquence
5. Le LCTS-2 ne produira pas de bruit d’alternateur. Il peut, comme pour tous les
processeurs de signaux, présenter un retour de masse dans le système qui résulte
dans du bruit étant introduit dans le système. Ce n’est pas une défaillance du produit
et peut être résolu par une bonne installation et l’utilisation du fil de mise à la masse
commun.
6. Si vous n’avez pas d’expérience en installation de composants électroniques mobiles,
ne connaissez pas la procédure à suivre pour ajuster le niveau du gain du système ou
ne comprenez pas entièrement ces instructions, Wirez vous recommande fortement
de demander l’assistance d’un installateur professionnel en électronique mobile pour
terminer l’installation et le réglage de votre système de divertissement mobile.
7. Remarque: Plusieurs unités de source avec mains libres Bluetooth ou Navigation
donnent uniquement une sortie audio à partir de ces sources sur les fils à haut-parleur
ou sorties RCA avant. Veuillez prendre cela en considération lors de vos connexions à
l’unité de source.
