2. I-AC Power Inlet: Connects to the main power supply using the provided power cord.
3. Input 4 (RCA): Unbalanced stereo input for line-level audio sources.
4. REC OUT (RCA): Unbalanced stereo output for recording or connecting to another ampokokuphila.
5. Input 1 Terminal Block: Balanced input for Line or Microphone sources.
6. Line/Mic/Phantom Power Switch (Input 1): Selects input type and enables/disables phantom power for microphones.
7. Mute Send Switch: Controls the mute function for external devices.

4. Ukusetha nokufakwa

4.1 Ukuqaqa

Khumula ngokucophelela i- amplifier and inspect it for any signs of damage. Retain the packaging materials for future shipping or storage.

4.2 Ukubekwa

Beka i- amplifier on a stable, flat surface. Ensure adequate ventilation around the unit to prevent overheating. Do not place it near heat sources or in direct sunlight.

4.3 Ukuxhuma Izipikha

Connect your speakers to the appropriate output terminals on the rear panel (COM, 4Ω, 25V, or 70V). Ensure that the speaker impedance and voltage rating match the amplifier's output to prevent damage. For 25V/70V systems, ensure proper transformer taps are used on the speakers.

4.4 Ukuxhuma Imithombo Yomsindo

• Ukufaka 1: For balanced line-level or microphone sources. Use the terminal block and set the Line/Mic/Phantom Power switch accordingly. If using a condenser microphone, enable phantom power.
• Input 2 (RCA): For unbalanced line-level audio sources. Connect your device (e.g., CD player, media player) using RCA cables.

4.5 Ukuxhuma Amandla

Connect the supplied AC power cord to the AC Power Inlet on the rear panel and then to a suitable wall outlet. Ensure the power switch on the front panel is in the OFF position before connecting to power.

5. Iziqondiso Zokusebenza

5.1 Ukuvula / Ukuvula

1. Qinisekisa ukuthi konke ukuxhumana kuvikelekile.
2. Turn down the Input 1 and Input 2 level controls to their minimum settings.
3. Press the Power switch on the front panel to turn the amplifier ON. The Power indicator light will illuminate.
4. To turn OFF, press the Power switch again.

5.2 Ukulungisa Ivolumu

Gradually increase the Input 1 or Input 2 level control for the active audio source until the desired volume is achieved. Monitor the Signal and Peak indicators:

• I Isiginali indicator should light up when audio is present.
• I Isiqongo indicator should only flash occasionally during the loudest parts of the audio. If it stays lit constantly, reduce the input level to prevent distortion and potential speaker damage.

5.3 Ukulawula Ithoni

Use the Bass and Treble controls to adjust the tonal characteristics of the audio output. Turn clockwise to boost frequencies and counter-clockwise to cut them. Start with the controls at the '0' (center) position for a flat response.

6. Isondlo

• Ukuhlanza: Disconnect the power cord before cleaning. Use a soft, dry cloth to wipe the exterior of the amplifier. Do not use liquid cleaners or aerosols.
• Ukungenisa umoya: Ensure that the ventilation openings are not blocked by dust or debris. Periodically check and clean if necessary.
• Isitoreji: Uma ugcina iyunithi isikhathi eside, yinqamule kugesi bese uyigcina endaweni epholile, eyomile, okungcono kakhulu ephaketheni layo lasekuqaleni.

7. Ukuxazulula izinkinga

If you experience issues with your Bogen CC4021 ampLifier, bheka izinkinga ezilandelayo nezisombululo:

• Awekho Amandla:
  • Hlola ukuthi intambo yamandla ixhumeke ngokuvikelekile yini kuzo zombili ampi-lifier kanye ne-wall outlet.
  • Qinisekisa ukuthi i-outlet yodonga iyasebenza.
  • Ensure the front panel Power switch is in the ON position.
• Akukho okukhipha umsindo:
  • Confirm that the audio source is playing and connected correctly to the ampokokufaka kwe-lifier.
  • Check that the Input level controls on the front panel are turned up.
  • Verify speaker connections and ensure they are securely attached to the correct terminals.
  • Ensure the Line/Mic/Phantom Power switch for Input 1 is set correctly for your source.
• Umsindo Ohlanekezelwe:
  • Reduce the Input level controls. If the Peak indicator is constantly lit, the signal is too high.
  • Check the audio source for distortion.
  • Qinisekisa ukuthi i-impedance yesipikha ifana ne- ampokukhiphayo kwe-lifier.
• Umsindo noma umsindo:
  • Hlola zonke izintambo zomsindo ukuze ubone ukuthi zixhumeke kahle futhi zonakele.
  • Try using different cables or audio sources to isolate the problem.
  • Ensure proper grounding of all connected equipment.

If the problem persists after trying these steps, please contact Bogen technical support.
