2.1 അൺപാക്കിംഗ്
Carefully remove the ULTRAGRAPH PRO FBQ1502 from its packaging. Retain all packaging materials for future transport or storage. Inspect the unit for any signs of damage that may have occurred during shipping. If damage is present, contact your dealer immediately.
2.2 കണക്ഷനുകൾ
The FBQ1502 features electronic servo-balanced inputs and outputs, supporting both 1/4" TRS and gold-plated XLR connectors. The servo function automatically adjusts for unbalanced signals, ensuring consistent signal levels. Connect your audio source (e.g., mixer, preamplifier) to the inputs and your audio destination (e.g., power amplifier, active speakers) to the outputs.
- പ്രധാന ഇൻപുട്ടുകൾ: Connect your stereo audio source to the main left and right inputs using balanced XLR or 1/4" TRS cables.
- പ്രധാന p ട്ട്പുട്ടുകൾ: Connect the main left and right outputs to your ampലൈഫയർ അല്ലെങ്കിൽ പവർഡ് സ്പീക്കറുകൾ.
- സബ് വൂഫർ putട്ട്പുട്ട്: Use the dedicated mono subwoofer output to connect to your subwoofer's input. This output has an adjustable crossover frequency.
- പവർ കണക്ഷൻ: Connect the supplied power cable to the unit and a suitable AC power outlet. Ensure the correct voltage is used as specified on the unit.
3. പ്രവർത്തന നിർദ്ദേശങ്ങൾ
3.1 പവർ ഓൺ/ഓഫ്
Locate the power switch on the front panel, typically on the right side. Press the switch to turn the unit ON. The power indicator will illuminate. To turn OFF the unit, press the switch again.
3.2 Graphic Equalization
The FBQ1502 features two 15-band graphic equalizer sections, one for each stereo channel. Each band corresponds to a specific frequency, allowing you to boost or cut that frequency's level. The faders provide precise control over the audio spectrum.
- ഫ്രീക്വൻസി ഫേഡറുകൾ: Adjust individual faders to boost (move up) or cut (move down) specific frequencies.
- റേഞ്ച് സ്വിച്ച്: Select between +/-6dB or +/-12dB equalization range using the RANGE switch. The +/-12dB setting provides a wider range of adjustment.
- In/Out Switch: Use the IN/OUT switch to bypass the equalizer section, allowing for A/B comparison of the processed and unprocessed signal.
3.3 FBQ ഫീഡ്ബാക്ക് ഡിറ്റക്ഷൻ സിസ്റ്റം
The patented FBQ Feedback Detection System is a key feature of the FBQ1502. When activated, the LEDs on the frequency faders illuminate to indicate frequencies that are causing feedback. This allows for quick identification and elimination of problematic frequencies.
- FBQ Button: Press the FBQ button to activate the feedback detection system.
- Feedback Indication: The brightest LED on a fader indicates the most critical feedback frequency. Lower the fader for that frequency to reduce or eliminate feedback.
- Audio Analyzer Mode: In normal operation (FBQ not active), the fader LEDs can also indicate frequency ranges with the highest energy levels, effectively functioning as an audio analyzer.
3.4 സബ്വൂഫർ put ട്ട്പുട്ട്
The dedicated mono subwoofer output allows for easy integration of a subwoofer into your audio system. The adjustable crossover frequency control enables you to set the upper frequency limit for the subwoofer output.
- Crossover Frequency Knob: Rotate this knob to adjust the crossover point for the subwoofer output, ensuring optimal bass management.
3.5 ലോ കട്ട് ഫിൽട്ടർ
The low cut filter removes unwanted low frequencies, such as floor rumble or hum, that can degrade audio quality. This helps to clean up the signal and improve clarity.
- LOW CUT Button: Press this button to engage the low cut filter.
3.6 Input Gain and Output Level
The FBQ1502 provides controls for adjusting input gain and monitoring output levels to ensure proper signal flow and prevent clipping.
- INPUT Gain Knob: Adjust this knob to set the input level of the signal entering the equalizer.
- OUTPUT LEVEL (dB) Meters: The 4-digit LED meters provide visual indication of the output signal level for each channel. Aim for levels that are strong but do not consistently peak into the red.
