Configuració

Abans de fer cap connexió, assegureu-vos que amplifier is powered off and disconnected from the AC outlet.

Connexió de fonts d'àudio

• Connect your audio source (e.g., pre-amplifier, receiver) to the IN LINE OUT RCA jacks on the rear panel using appropriate RCA cables.
• If connecting additional amplifiers in a daisy-chain configuration, use the OUT LINE OUT RCA jacks to pass the audio signal to the next ampmés viu.

Connexió d'altaveus

El amplifier utilizes 4-pole detachable Euroblock connectors for speaker connections. Ensure correct polarity (+ to + and - to -) for all connections.

• For Stereo (4Ω or 8Ω): Connect speaker wires to the L+ L- R+ R- terminals. Set the OUTPUT SEL switch to '4Ω' or '8Ω' depending on your speaker impedance.
• For Bridged (8Ω): Connect a single 8-ohm speaker to the L+ and R+ terminals. Set the OUTPUT SEL switch to 'Bridge'.
• El amplifier supports speaker wire up to 12 AWG. Strip approximately 8-10mm of insulation from the speaker wire ends before inserting them into the Euroblock connector and tightening the screws.

Connexió d'alimentació

Connecteu el cable d'alimentació de CA subministrat a amplifier's AC inlet and then to a standard wall outlet (100-240V, 50/60Hz).

12V Trigger Connection (Optional)

• To use the 12V trigger feature, connect a 12V trigger cable from your source device (e.g., AV receiver) to the ENTRADA port al ampmés viu.
• To control other devices (e.g., another amplifier or screen), connect a 12V trigger cable from the amplificadors DISPARACIÓ port to the controlled device's trigger input.

Instruccions de funcionament

Modes de potència

El amplifier offers three power modes, selectable via the PODER switch on the rear panel:

• ACTIVITAT: El amplifier remains continuously powered on.
• DISPARADOR: El amplifier powers on/off in response to a 12V trigger signal connected to the ENTRADA port.
• AUTOMÀTIC: El amplifier powers on automatically when an audio signal is detected and enters standby when no signal is present for a period.

Ajust de volum

A volume gain adjustment knob is located on the rear panel. This is a 'set-and-forget' control, typically adjusted with a small screwdriver, to balance the amplifier's output with other components in your system. Adjust this to achieve desired sound levels without distortion.

Output Selection (Bridged/Stereo)

Utilitza el OUTPUT SEL switch on the rear panel to select between stereo (4Ω or 8Ω) or bridged (8Ω) output modes. Ensure this setting accurately matches your speaker configuration to prevent damage to the ampmés alt o altaveus.

Manteniment

• Mantenir el amplifier clean by wiping it with a soft, dry cloth. Do not use liquid or aerosol cleaners, as they may damage the finish or internal components.
• Ensure adequate ventilation around the unit to prevent overheating. Do not place the amplifier in an enclosed space without proper airflow.
• Regularly check all cable connections for security and ensure they are free from corrosion or damage.
• If the unit is not in use for an extended period, disconnect it from the power outlet.

Resolució de problemes

Sense poder

• Comproveu si el cable d'alimentació està connectat correctament a tots dos amplifier and a functional wall outlet.
• Verifiqueu el PODER switch on the rear panel is set to 'ON', 'TRIGGER' (with an active trigger signal), or 'AUTO' (with an audio signal present).

Sense so

• Check all audio input and speaker connections for proper seating and correct polarity.
• Verify the audio source is active and producing sound.
• Adjust the rear panel volume gain control. Ensure it is not set to minimum.
• Assegureu-vos el OUTPUT SEL switch matches your speaker impedance and configuration (stereo or bridged).

Soroll de brunzit o brunzit

• Ensure all audio cables are properly shielded and securely connected.
• If using the 12V trigger, try disconnecting the trigger cable and using the 'AUTO' power mode instead, as some trigger setups can introduce noise.
• Comproveu si hi ha bucles de terra. Intenteu connectar tots els equips d'àudio a la mateixa regleta.
• Adjust the rear panel volume gain control; sometimes lowering it can reduce hiss or hum, though it may reduce maximum output.

Sobreescalfament

• Assegureu-vos el amplifier has sufficient ventilation. Do not block the top or side vents.
• Reduce the volume level if the unit feels excessively hot.
• El amplifier has built-in thermal protection and may shut down if it overheats. Allow it to cool down before resuming operation.
