Bagpaneltilslutninger

Figur 3: Tilslutninger på bagpanelet
- Indgangsstik: XLR and 1/4" (6.5mm Jack) balanced inputs for Channel 1 and Channel 2.
- Udgangsstik: 3 Speakon outputs for Channel A, Channel B, and Bridged mode. 5-Way binding banana plug outputs are also available.
- Mode Switch: Selects between Stereo, Parallel, and Bridged operating modes.
- Crossover switch: Selects between Bypass (full range), Sub 160Hz, and Sub 80Hz for low-pass filtering.
- Kontakt til jordløft: Helps eliminate hum and noise caused by ground loops.
- Strømindgang: Tilslut det medfølgende AC-strømkabel her.
Tilslutning af dit system
- Sluk: Sørg for ampapparatet er slukket, før der foretages nogen tilslutninger.
- Indgangsforbindelser: Connect your audio source (e.g., mixer, DJ controller) to the XLR or 1/4" inputs on the rear panel. Use balanced cables for optimal performance.
- Udgangsforbindelser: Connect your passive loudspeakers to the Speakon or 5-Way binding banana plug outputs. Ensure correct polarity (+ to + and - to -).
- Valg af tilstand: Use the Mode switch to select your desired operating mode (Stereo, Parallel, or Bridged).
- Crossover Setting: Adjust the Crossover switch based on your speaker setup (Bypass for full-range speakers, Sub 160Hz or Sub 80Hz for subwoofers).
- Tænd: Once all connections are secure, turn the amplifier ON using the front panel power switch.
Drift
Betjening af frontpanel
- Justering af lydstyrke: Use the Channel 1 and Channel 2 level controls to set the desired output volume for each channel.
- Overvågningsstatus: Vær opmærksom på LED-indikatorerne:
- Signal LED: Lyser, når der er et lydsignal.
- Clip LED: Illuminates when the input signal is too high, causing clipping or distortion. Reduce the input level from your source or the amplifier's channel level.
- Protect LED: Lyser op, hvis amplifier detects a fault (e.g., short circuit, overheating) and activates protection mode.
- Bridge LED: Lyser, når amplifier is operating in Bridged mode.
Driftstilstande
- Stereo-tilstand: Each channel operates independently, providing separate left and right audio signals. Ideal for standard stereo setups.
- Parallel tilstand: Both channels receive the same input signal but operate independently. Useful for driving multiple speakers with a mono signal.
- Brokoblet tilstand: Combines the power of both channels into a single, higher-power output. Typically used for driving a single, high-power subwoofer.
Crossover-funktionalitet
- Bypass: Sends a full-range audio signal to the outputs. Suitable for main speakers.
- Sub 160Hz / Sub 80Hz: Activates a low-pass filter, allowing only frequencies below 160Hz or 80Hz (respectively) to pass through. Essential when driving subwoofers to prevent higher frequencies from reaching them.
Opretholdelse
- Rensning: Tør regelmæssigt ydersiden af amplifier with a dry, soft cloth. Do not use liquid cleaners or solvents.
- Ventilation: Ensure the front and rear ventilation openings are clear of dust and obstructions to maintain proper airflow and prevent overheating. The variable speed cooling fan helps regulate internal temperature.
- Udskiftning af sikring: Hvis amplifier does not power on, check the fuse located near the AC power input on the rear panel. Replace with a fuse of the same type and rating (refer to specifications for details).
Fejlfinding
| Problem | Mulig årsag | Løsning |
|---|---|---|
| Ingen strøm | Power cable disconnected, blown fuse | Check power cable connection, replace fuse if necessary. |
| Ingen lydudgang | Incorrect input/output connections, low volume, Protect LED on | Verify all cable connections, increase channel level, check for faults if Protect LED is on. |
| Forvrænget lyd | Input signal too high (Clipping), faulty cables, speaker impedance mismatch | Reduce input level (Clip LED off), check/replace cables, ensure speaker impedance matches amplifiers muligheder. |
| Humming/Noise | Ground loop, faulty cables | Activate Ground Lift switch, use balanced cables, check/replace cables. |
| Protect LED on | Overheating, short circuit, DC output protection | Turn off unit, check speaker connections for shorts, ensure adequate ventilation. Allow unit to cool down. |
