2. Nastavitev
2.1 Razpakiranje in namestitev
Previdno razpakirajte amplifier and inspect it for any signs of damage. Place the ampNapravo namestite v dobro prezračevanem prostoru, po možnosti v standardno 19-palčno omaro za opremo. Zagotovite zadosten pretok zraka okoli enote, da preprečite pregrevanje.
2.2 Prekrivanje sprednje ploščeview
- Stikalo za vklop: Obrne amplifier VKLOP/IZKLOP.
- Channel Gain Controls: Adjust the input sensitivity for each of the four channels.
- Signalne LED diode: Indicate the presence of an input signal.
- Clip LED: Illuminate when the output signal is clipping, indicating potential distortion. Reduce the input level if these LEDs light up frequently.
- Power LED: Navedite operativno stanje vsakega kanala.
2.3 Zadnja plošča čezview in Povezave
- Inputs (CH A, CH B, CH C, CH D): XLR and 1/4-inch TRS combo jacks for connecting audio sources.
- Outputs (CH A, CH B, CH C, CH D): Speakon connectors for connecting speakers.
- Stikala načina: Select between Stereo, Parallel, or Bridged operation for each pair of channels (A/B and C/D).
- Crossover stikala: Select between Full Range, Low-Cut (for subwoofers), or High-Cut (for top speakers) for each pair of channels.
- Vhodna moč: Standard IEC power connector.
- Varovalka: Zagotavlja zaščito pred preobremenitvijo.
2.4 Connecting Audio Sources and Speakers
Zagotovite amplifier is turned OFF before making any connections.
- Vhodne povezave: Priključite svoj avdio vir (mešalni mešalnik, prednastavitev)amplifier, etc.) to the XLR or 1/4-inch TRS combo inputs on the rear panel. Use balanced cables for optimal noise rejection.
- Priključki zvočnikov: Connect your passive speakers to the Speakon outputs. Ensure correct polarity (+ to + and - to -).
- Izbira načina: Use the mode switches to select the desired operation:
- Stereo: Vsak kanal deluje neodvisno in poganja ločen zvočnik.
- vzporedno: Input signal from Channel A is sent to both Channel A and Channel B outputs (and similarly for C/D), allowing both channels to drive speakers with the same mono signal.
- Premostitveni: Combines the power of two channels (A+B or C+D) to drive a single, higher-power speaker (typically a subwoofer). Ensure the speaker impedance is compatible with bridged mode (usually 4 or 8 Ohms).
- Nastavitve križanja: Use the crossover switches to optimize the frequency response for your speakers:
- Celoten obseg: Sends the full audio spectrum to the speakers.
- Nizek izrez: Filters out low frequencies, ideal for top speakers when used with subwoofers.
- Visoki rez: Filters out high frequencies, ideal for subwoofers.

3. Navodila za uporabo
3.1 Powering On and Initial Level Setting
- Ensure all gain controls on the amplifier are set to their minimum position.
- Turn on your audio source equipment first.
- Flip the Power Switch on the Behringer NU4-6000 to the ON position. The Power LEDs should illuminate.
- Slowly increase the gain controls for each channel until the desired volume is reached. Monitor the Signal and Clip LEDs to avoid distortion.
3.2 Understanding "Zero-Attack" Limiters
The "Zero-Attack" limiters are designed to provide maximum output level with reliable overload protection. They automatically detect when the signal is approaching clipping and dynamically reduce the gain to prevent distortion and protect your speakers.
3.3 Class-D Technology and Switch-Mode Power Supply
The NU4-6000 utilizes revolutionary High-Density Class-D amplifier technology, which ensures cool-running operation with "near-zero" thermal buildup. Coupled with an ultra-efficient switch-mode power supply, the amplifier delivers noise-free audio, superior transient response, and low power consumption, making it ideal for extended use.

4. Vzdrževanje
To ensure the longevity and optimal performance of your Behringer NU4-6000 ampza vzdrževanje, upoštevajte ta navodila za vzdrževanje:
- Čiščenje: Redno čistite zunanjost amplifier with a soft, dry cloth. Avoid using abrasive cleaners or solvents. Ensure ventilation grilles are free from dust and debris to maintain proper airflow.
- Prezračevanje: Vedno upravljajte amplifier in a well-ventilated environment. Do not block the ventilation openings. Overheating can severely damage the unit.
- Napajalni kabel: Inspect the power cord periodically for any damage. Replace immediately if frayed or broken.
- Shranjevanje: Ko naprave dalj časa ne uporabljate, jo shranite ampShranjujte na hladnem in suhem mestu, stran od neposredne sončne svetlobe in ekstremnih temperatur.
5. Odpravljanje težav
If you encounter issues with your Behringer NU4-6000, refer to the following common troubleshooting steps:
- Brez napajanja:
- Preverite, ali je napajalni kabel varno priključen na oba ampvžigalnik in delujočo električno vtičnico.
- Preverite, ali je vtičnica aktivna.
- Check the circuit breaker on the rear panel; reset if tripped.
- Ni zvoka:
- Ensure all audio input and speaker output cables are correctly and securely connected.
- Verify that the input source is active and sending a signal.
- Check the gain controls on the amplifier; ensure they are not set to minimum.
- Confirm that the correct mode (Stereo, Parallel, Bridged) is selected for your setup.
- Distorted Sound / Clip LED On:
- Reduce the input gain on the amplifier or the output level from your audio source.
- Ensure your speakers are correctly matched to the amplifier's impedance and power output.
- Pregrevanje:
- Zagotovite amplifier has adequate ventilation and that no vents are blocked.
- Check speaker impedance; operating with too low an impedance can cause overheating.
- Reduce the overall volume or continuous high-power operation.
