Menyambung Sistem Anda
- Matikan: Memastikan amplifier is turned OFF before making any connections.
- Sambungan Input: 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.
- Sambungan Keluaran: Connect your passive loudspeakers to the Speakon or 5-Way binding banana plug outputs. Ensure correct polarity (+ to + and - to -).
- Pemilihan Mod: Use the Mode switch to select your desired operating mode (Stereo, Parallel, or Bridged).
- Tetapan Silang Silang: Adjust the Crossover switch based on your speaker setup (Bypass for full-range speakers, Sub 160Hz or Sub 80Hz for subwoofers).
- Hidupkan kuasa: Once all connections are secure, turn the amplifier ON using the front panel power switch.
Beroperasi
Operasi Panel Hadapan
- Melaraskan Kelantangan: Use the Channel 1 and Channel 2 level controls to set the desired output volume for each channel.
- Status Pemantauan: Perhatikan penunjuk LED:
- LED isyarat: Menyala apabila isyarat audio hadir.
- LED Klip: 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.
- Lindungi LED: Menerangi jika amplifier detects a fault (e.g., short circuit, overheating) and activates protection mode.
- Bridge LED: Bercahaya apabila amplifier is operating in Bridged mode.
Mod Pengendalian
- Mod Stereo: Each channel operates independently, providing separate left and right audio signals. Ideal for standard stereo setups.
- Mod Selari: Both channels receive the same input signal but operate independently. Useful for driving multiple speakers with a mono signal.
- Mod Jambatan: Combines the power of both channels into a single, higher-power output. Typically used for driving a single, high-power subwoofer.
Fungsi Crossover
- Pintasan: 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.
Penyelenggaraan
- Pembersihan: Lap bahagian luar secara berkala amplifier with a dry, soft cloth. Do not use liquid cleaners or solvents.
- Pengudaraan: 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.
- Penggantian fius: Sekiranya 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).
Menyelesaikan masalah
| Masalah | Kemungkinan Punca | Penyelesaian |
|---|---|---|
| Tiada kuasa | Power cable disconnected, blown fuse | Check power cable connection, replace fuse if necessary. |
| Tiada keluaran bunyi | Incorrect input/output connections, low volume, Protect LED on | Verify all cable connections, increase channel level, check for faults if Protect LED is on. |
| Bunyi herot | Input signal too high (Clipping), faulty cables, speaker impedance mismatch | Reduce input level (Clip LED off), check/replace cables, ensure speaker impedance matches ampkeupayaan liifier. |
| 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. |
