4.1 Controles del panel frontal

The front panel of the BK-SAM300 features essential controls for power and audio adjustments.

Figura 4.1: Delantero y trasero View of the BK-SAM300 Amplifier. This image displays both the front panel with its controls and the rear panel with all input/output connections.

• Botón de encendido: Alterna el ampEncendido o apagado del elevador.
• Phase Control (0° - 180°): Adjusts the phase of the subwoofer output relative to the main speakers. This helps to ensure that the subwoofer's sound waves align correctly with those of the main speakers, preventing cancellation or reinforcement issues at the crossover frequency.
• FREQ (Crossover Frequency) Control: Sets the upper frequency limit for the subwoofer. Frequencies above this setting will be filtered out. Adjustable from approximately 40Hz to 120Hz.
• GAIN (Volume) Control: Adjusts the overall output level of the subwoofer amplifier. Use this to balance the subwoofer's volume with the rest of your audio system.

4.2 Conexiones y controles del panel trasero

The rear panel houses all the input and output connections, along with additional settings for advanced configuration.

Figure 4.2: Rear Panel of the BK-SAM300 Amplifier. This image provides a detailed view of all input and output terminals, including Hi Level, Line, LFE, Bass Boost, 12V Trigger, and Subwoofer Output.

• HI LEVEL IN (Speaker Level Input): Connects directly to the speaker outputs of your receiver or amplifier. Use this if your receiver does not have a dedicated subwoofer output or LFE output.
• HI LEVEL OUT (Speaker Level Output): Passes the full-range audio signal from the HI LEVEL IN to your main speakers.
• LINE IN (RCA Input): Standard RCA stereo inputs for connecting to the pre-out or line-out of your receiver or audio source.
• LINE OUT (RCA Output): Passes the audio signal from the LINE IN to another ampamplificador o dispositivo de audio.
• LFE INPUT (RCA Input): Dedicated input for connecting to the LFE (Low-Frequency Effects) output of an AV receiver. This bypasses the amplifier's internal crossover, relying on the receiver's bass management.
• BASS BOOST (Level & Freq):
  • Level (0dB to 12dB): Adjusts the intensity of the bass boost.
  • Freq (25Hz to 50Hz): Selecciona la frecuencia central en la que se aplica el refuerzo de graves.
  

  Figure 4.3: Detail of Bass Boost Controls. This image highlights the Level and Freq knobs for fine-tuning the bass boost.

• REMOTE TURN ON (Manual, Auto, 12V Trigger): Selecciona el amplifier's power-on mode.
  • Manual: Amplifier is turned on/off manually via the front panel power button.
  • Auto: Amplifier automatically turns on when an audio signal is detected and enters standby mode when no signal is present for a period.
  • Activador de entrada/salida de 12 V: Permite la amplifier to be turned on/off by a 12V DC trigger signal from a compatible receiver or control system.
• SUBWOOFER OUTPUT (Binding Posts): Connects to your passive subwoofer using speaker wire. Ensure correct polarity (+ to + and - to -). The ampLifier es estable hasta una impedancia de 4 ohmios.

6. Instrucciones de funcionamiento

6.1 Encendido / Apagado

The BK-SAM300 offers three power-on modes:

• Modo manual: Establecer el ENCENDIDO REMOTO switch to "Manual". Press the front panel Botón de encendido Para girar el ampmás vivaz encendido o apagado.
• Modo automático: Establecer el ENCENDIDO REMOTO switch to "Auto". The amplifier will automatically turn on when an audio signal is detected at the inputs and will enter standby mode after approximately 15-20 minutes of no audio signal.
• 12V Trigger Mode: Connect a 12V DC trigger cable from your source component (e.g., AV receiver) to the ENTRADA DE DISPARADOR DE 12 V terminal. Set the ENCENDIDO REMOTO switch to "12V Trigger". The amplifier will power on/off with the source component.

6.2 Ajuste de controles

Optimal sound quality depends on proper adjustment of the amplifier's controls to match your subwoofer and listening environment.

• GAIN (Volume): Start with the GAIN control at its minimum setting. Play some audio with significant bass content. Slowly increase the GAIN until the subwoofer's output blends seamlessly with your main speakers. Avoid setting the gain too high, as this can lead to distortion.
• FREQ (Frecuencia de cruce):
  • Si se utiliza el ENTRADA LFE, this control is bypassed. Set your AV receiver's subwoofer crossover frequency.
  • Si se utiliza ENTRADA DE LINEA or ALTO NIVEL EN, adjust the FREQ control to blend the subwoofer's output with your main speakers. A good starting point is typically 80Hz-100Hz, but this may vary depending on the size and frequency response of your main speakers. Smaller main speakers usually require a higher crossover frequency.
• FASE (0° - 180°): The phase control helps to ensure that the subwoofer's sound waves are in sync with your main speakers.
  • Play music with a consistent bass line.
  • While listening from your primary listening position, slowly adjust the PHASE control from 0° to 180°.
  • Stop at the position where the bass sounds the loudest and most impactful. If the bass sounds weak or hollow, try adjusting the phase.
• REFUERZO DE GRAVES: Use the BASS BOOST controls (Level and Freq) to fine-tune the low-frequency response.
  • Frec: Select the specific low frequency (25Hz to 50Hz) you wish to boost.
  • Nivel: Adjust the amount of boost (0dB to 12dB) at the selected frequency. Use sparingly to avoid muddy or boomy bass.

7. Mantenimiento

• Limpieza: Desconectar el amplifier from power before cleaning. Use a soft, dry cloth to wipe down the exterior. Do not use liquid cleaners or aerosol sprays.
• Ventilación: Ensure that the ventilation openings are not blocked by dust or debris. Periodically check and clean if necessary to maintain proper airflow.
• Almacenamiento: Si almacena el amplifier for an extended period, disconnect it from power and store it in a cool, dry place, away from direct sunlight and extreme temperatures.
