4. Nastavení
4.1 Vybalení a kontrola
Opatrně vyjměte amplifier from its packaging. Inspect the unit for any signs of damage that may have occurred during transit. If damage is found, contact your dealer immediately.
4.2 Montáž do racku
The FULODE 2CH-PA is designed for standard 1U rack mounting. Secure the amplifier to a rack using appropriate rack screws. Ensure there is sufficient space for ventilation around the unit.
4.3 Připojení zdrojů zvuku
Připojte zdroj zvuku (např. mixážní pult, audio rozhraní) k amplifier's XLR input connectors (CH.A INPUT, CH.B INPUT) on the rear panel. Use high-quality XLR cables for optimal signal integrity.
4.4 Připojení reproduktorů
Connect your speakers to the Speakon output connectors (CH.A OUTPUT, CH.B OUTPUT) on the rear panel. Ensure correct polarity and use appropriate gauge speaker cables for your setup.
4.5 Připojení napájení
Connect the provided AC power cord to the amplifier's power inlet and then to a suitable grounded AC power outlet. Ensure the power switch on the front panel is in the OFF position before connecting to power.
4.6 Operating Mode Selection
The amplifier supports three operating modes: Stereo, Parallel, and Bridge. Select the desired mode using the STEREO/PARALLEL/BRIDGE switch on the rear panel. Vždy vypněte amplifier and set volume knobs to minimum before changing modes.
- Stereo Mode (Default): Set the switch to STEREO (button released). Input signal to CH.A outputs to CH.A, and input signal to CH.B outputs to CH.B. Each channel operates independently.
- Paralelní režim: Press the switch to select PARALLEL mode. Input signal to CH.A or CH.B; both channels receive the same signal and have independent level control.
- Přemostěný režim: Press the switch to select BRIDGED mode. Use INPUT CH.A only and wire the speaker to +1 / -2 of the CH.A Speakon output for mono, high-power output.

5. Návod k obsluze
5.1 Zapnutí/vypnutí
- Ensure all connections are secure and volume controls are set to minimum.
- Flip the power switch on the front panel to the ON position. The amplifier will undergo a 3-second soft-start delay.
- To power off, set the power switch to the OFF position.
5.2 Adjusting Gain Controls
Each channel (CH.A and CH.B) has an independent gain control knob on the front panel. Slowly increase the gain to achieve the desired output level. Monitor the signal and limit indicators to prevent clipping.
5.3 Pochopení indikátorů
- SIGNÁLNÍ LED: Illuminates when an audio signal is present on the respective channel.
- LIMIT LED: Illuminates when the output signal is approaching clipping. Reduce the gain if this LED frequently lights up to prevent distortion and speaker damage.
- LED PROTECT: Rozsvítí se, pokud amplifier enters protection mode due to overload, overheat, DC fault, or short circuit. The amplifier will mute output until the condition is resolved.
6. Údržba
6.1 Čištění
Pravidelně čistěte vnější část amplifier with a soft, dry cloth. Do not use abrasive cleaners, solvents, or waxes. Ensure ventilation openings are free from dust and debris.
6.2 Větrání
Periodically check that the cooling fan is operating correctly and that airflow is not obstructed. Proper ventilation is crucial for maintaining optimal operating temperatures and preventing overheating.
