5. Configuració i instal·lació

Follow these steps to connect your Monoprice 4-Channel Speaker Selector to your audio system.

5.1 Identify Connections

Figura 2: Rear panel of the speaker selector. Note the "L INPUTS R" terminals on the left for amplifier connection and "OUTPUTS" terminals (1-4) for speaker connections.

The rear panel of the speaker selector features one set of stereo inputs labeled "L INPUTS R" for connecting your amplifier or receiver, and four sets of stereo outputs labeled "OUTPUTS 1" through "OUTPUTS 4" for connecting your speaker pairs.

5.2 Instruccions de cablejat

1. Apagar: Assegureu-vos el vostre amplifier/receiver is turned off and unplugged from the power outlet before making any connections.
2. Prepare Speaker Wires: Strip approximately 1/2 inch (1.25 cm) of insulation from the ends of all speaker wires. Twist the bare wire strands tightly.
3. Connecta't Amplifier to Inputs:
   • Connecteu el Esquerra (+) output terminal of your ampmés viu al Esquerra (+) input terminal of the speaker selector (under "L INPUTS R").
   • Connecteu el Esquerra (-) output terminal of your ampmés viu al Esquerra (-) input terminal of the speaker selector.
   • Connecteu el Dreta (+) output terminal of your ampmés viu al Dreta (+) input terminal of the speaker selector.
   • Connecteu el Dret (-) output terminal of your ampmés viu al Dret (-) input terminal of the speaker selector.

   Ensure correct polarity (+ to + and - to -) for optimal sound quality.

4. Connect Speakers to Outputs: For each pair of speakers (Zone 1, 2, 3, or 4):
   • Connecteu el Esquerra (+) terminal of your speaker to the Esquerra (+) output terminal for the desired zone on the speaker selector.
   • Connecteu el Esquerra (-) terminal of your speaker to the Esquerra (-) output terminal for the desired zone on the speaker selector.
   • Connecteu el Dreta (+) terminal of your speaker to the Dreta (+) output terminal for the desired zone on the speaker selector.
   • Connecteu el Dret (-) terminal of your speaker to the Dret (-) output terminal for the desired zone on the speaker selector.

   Maintain consistent polarity for all speaker connections.

5. Impedance Protection Switch: Locate the impedance protection switch (often on the rear or bottom of the unit).
   • ACTIVITAT: Activates the protection circuit. Recommended for amplifiers with minimum impedance ratings below 8 ohms, or when connecting multiple pairs of speakers simultaneously to prevent amplifier overload. This limits power handling to 70W per channel.
   • DESACTIVAT: Disables the protection circuit. Allows for higher power handling (up to 140W per channel) but requires careful consideration of your amplifier's minimum impedance rating and the total impedance of connected speakers. Consult your ampmanual del lificador.
6. Col·locació: Place the speaker selector in a well-ventilated area, away from heat sources and direct sunlight.

6. Instruccions de funcionament

Once all connections are made and verified, you can begin using your speaker selector.

1. Encès: Connecteu i engegueu el vostre amplificador/receptor.
2. Select Speaker Zones: Use the individual push-buttons on the front panel of the speaker selector to turn on or off each pair of connected speakers (Zone 1, 2, 3, or 4).
   • Pressing a button will engage that speaker zone.
   • Pressing it again will disengage the zone.
   • You can select one, multiple, or all speaker zones simultaneously, depending on your listening preference and amplifier capabilities.
3. Ajustar el volum: Control the overall volume using your amplifier/receiver's volume control.

Note on Impedance Protection: If the impedance protection circuit is enabled, you can safely operate multiple pairs of speakers without concern for amplifier overload. If it is disabled, be mindful of your amplifier's minimum impedance rating when engaging multiple speaker pairs. Operating an amplifier below its minimum impedance rating can cause damage.

7. Manteniment

The Monoprice 4-Channel Speaker Selector requires minimal maintenance.

• Neteja: Feu servir un drap suau i sec per netejar l'exterior de la unitat. No utilitzeu netejadors líquids ni aerosols.
• Ventilació: Assegureu-vos que les ranures de ventilació de la unitat no estiguin bloquejades per evitar el sobreescalfament.
• Connexions: Periodically check all speaker wire connections to ensure they remain secure.
