4.1 Kontrole sprednje plošče

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

Slika 4.1: spredaj in zadaj 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.

• Gumb za vklop: Preklopi ampvklop ali izklop napajanja življenjske naprave.
• 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.

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 amplifier ali avdio naprava.
• 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): Selects the center frequency at which the bass boost is applied.
  

  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): Izbere amplifier's power-on mode.
  • Ročno: Amplifier is turned on/off manually via the front panel power button.
  • Samodejno: Amplifier automatically turns on when an audio signal is detected and enters standby mode when no signal is present for a period.
  • 12V sprožilni vhod/izhod: Omogoča 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 je stabilen do impedance 4 ohmov.

• AC VOLTAGE SELECTOR (120V/240V): Izbere ustrezen vhodni voltage za vašo regijo. Ensure this is set correctly before plugging in the amplifier.
• AC napajalni vhod: Priključi priložen napajalni kabel.

5. Nastavitev

5.1 Namestitev

Postavite amplifier in a location that allows for adequate ventilation. Avoid enclosed spaces or stacking other components directly on top of the amplifier. Keep it away from direct sunlight, heat sources, and moisture. Ensure it is placed on a stable, level surface.

5.2 Priključitev Amplifier

Choose one of the following connection methods based on your audio system's capabilities:

Method A: Using LFE Input (Recommended for AV Receivers with Subwoofer Output)

1. Connect an RCA cable from the LFE or Subwoofer Pre-Out jack on your AV receiver to the LFE INPUT jack on the BK-SAM300.
2. Connect your passive subwoofer to the IZHOD SUBWOOFERJA binding posts on the BK-SAM300 using appropriate gauge speaker wire. Ensure correct polarity (+ to + and - to -).
3. Proceed to Section 5.3 for power connection.

Method B: Using Line Level Inputs (for Stereo Receivers or Pre-Outs)

1. Connect RCA cables from the Pre-Out or Line-Out jacks of your receiver/pre-ampdvigalo za LINE IN (Left and Right) jacks on the BK-SAM300.
2. Connect your passive subwoofer to the IZHOD SUBWOOFERJA binding posts on the BK-SAM300 using appropriate gauge speaker wire. Ensure correct polarity (+ to + and - to -).
3. Proceed to Section 5.3 for power connection.

Method C: Using High Level Inputs (for Receivers without Dedicated Subwoofer/Pre-Outs)

1. Connect speaker wires from the main speaker outputs of your receiver/ampdvigalo za VISOKA STOPNJA IN (Left and Right) binding posts on the BK-SAM300. Ensure correct polarity.
2. (Optional) If you wish to pass the signal through to your main speakers, connect speaker wires from the HI. STOPNJA VEN binding posts on the BK-SAM300 to your main speakers.
3. Connect your passive subwoofer to the IZHOD SUBWOOFERJA binding posts on the BK-SAM300 using appropriate gauge speaker wire. Ensure correct polarity (+ to + and - to -).
4. Proceed to Section 5.3 for power connection.

5.3 Napajalni priključek

1. Before connecting the power cord, ensure the AC VOLTAGE IZBORNIK stikalo na zadnji plošči nastavljeno na pravilno glasnosttage for your region (120V or 240V). Incorrect setting can damage the unit.
2. Priloženi napajalni kabel priključite na Vhod za izmenični tok on the rear panel of the amplifier.
3. Drugi konec napajalnega kabla priključite v ustrezno stensko vtičnico.

6. Navodila za uporabo

6.1 Vklop/izklop

The BK-SAM300 offers three power-on modes:

• Ročni način: Nastavite DALJINSKI VKLOP switch to "Manual". Press the front panel Gumb za vklop obrniti ampvklop ali izklop dvižnika.
• Samodejni način: Nastavite DALJINSKI VKLOP 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 12V TRIGGER IN terminal. Set the DALJINSKI VKLOP switch to "12V Trigger". The amplifier will power on/off with the source component.

6.2 Prilagajanje kontrol

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 (Crossover Frequency):
  • Če uporabljate LFE INPUT, this control is bypassed. Set your AV receiver's subwoofer crossover frequency.
  • Če uporabljate LINE IN or VISOKA STOPNJA IN, 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.
• PHASE (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.
• BASS BOOST: Use the BASS BOOST controls (Level and Freq) to fine-tune the low-frequency response.
  • frekvenca: Select the specific low frequency (25Hz to 50Hz) you wish to boost.
  • stopnja: Adjust the amount of boost (0dB to 12dB) at the selected frequency. Use sparingly to avoid muddy or boomy bass.

7. Vzdrževanje

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