• LED-aanwysers:
  • Krag: Verlig wanneer die eenheid aangeskakel is.
  • Beperker: Indicates when the built-in limiter is active to prevent clipping.
  • sein: Shows the presence and level of the input audio signal (-20 dB, -10 dB, -5 dB, 0 dB).

Agterpaneel

Prent: Agter view of the Backstage HCF-PRO-20 Power Amplifier, displaying input connectors (XLR, TRS), output connectors (binding posts, Speakon), mode switches (Normal, Stereo, Bridge), low-cut filters, input sensitivity DIP switches, and the AC power inlet with fuse.

• Invoerverbindings: XLR and 1/4" TRS balanced inputs for Channel 1 and Channel 2.
• Input Thru: XLR output for daisy-chaining the input signal to another amplewendiger.
• Uitsetverbindings: Binding posts and Speakon connectors for connecting loudspeakers for Channel 1 and Channel 2.
• Modusskakelaar: Selects between NORMAL (dual mono), STEREO, and BRIDGE operating modes.
• Lae sny filter: Switches to activate a low-cut filter (e.g., 20Hz, 200Hz) for each channel.
• Input Balance/Sensitivity DIP Switches: Allows adjustment of input sensitivity (e.g., 0 dB, -3 dB, -6 dB, -12 dB).
• Grondhyserskakelaar: Helps eliminate hum by disconnecting the signal ground from the chassis ground.
• AC-kraginlaat: Standard IEC power connector for the main power cable.
• Sekeringhouer: Contains the main protective fuse (F 15A 250V).

Opstelling

1. Plasing: Plaas die amplifier in a well-ventilated area, away from direct heat sources. Ensure it is securely mounted if rack-mounted.
2. Skakel af: Verseker die amplifier's power switch is in the OFF position before making any connections.
3. Invoerverbindings: Koppel jou klankbron (menger, voorversterker)amplifier) to the XLR or 1/4" TRS input connectors on the rear panel for Channel 1 and Channel 2.
4. Uitvoerverbindings: Connect your loudspeakers to the appropriate output connectors (Speakon or binding posts). Ensure correct polarity (+ to +, - to -).
5. Moduskeuse: Set the MODE switch on the rear panel to STEREO for two separate channels, NORMAL for dual mono, or BRIDGE for mono operation with increased power. Refer to your speaker impedance for bridge mode compatibility.
6. Lae sny filter: If desired, engage the low-cut filter switches to remove unwanted low frequencies.
7. Kragverbinding: Connect the supplied AC power cable to the amplifier's AC inlet and then to a grounded power outlet.

Bedryf

1. Aanvanklike krag aan: Turn on your audio source first, then switch the amplifier's power to ON.
2. Volume aanpassing: Start with the input level controls on the front panel set to minimum. Gradually increase them to achieve the desired output volume.
3. Moniteringsaanwysers: Observe the SIGNAL LEDs to ensure a healthy input signal. The LIMITER LEDs should only flash occasionally during peak signals. If they are constantly lit, reduce the input level to prevent distortion and potential speaker damage.
4. Skakel af: As jy klaar is, skakel die amplifier first, then your audio source.

Onderhoud

• Skoonmaak: Gebruik 'n sagte, droë lap om die buitekant van die ampMoenie vloeibare skoonmaakmiddels of oplosmiddels gebruik nie.
• Ventilasie: Regularly check that the ventilation grilles are free from dust and debris to ensure proper airflow.
• Sekering vervanging: As die amplifier does not power on, check the fuse in the rear panel. Replace it only with a fuse of the same type and rating (F 15A 250V).
• Berging: As die stoor van die ampMaak seker dat dit in 'n droë, stofvrye omgewing is.
