- Aircraft-grade aluminum body with precision CNC integrated molding, 150-mesh sandblasting + anodizing. Side grilles enhance passive heat dissipation.
- SNR up to 115dB, channel separation 75dB, with a new audio-specific switching power supply.
- Built-in overheating and overcurrent protection circuits, standby power <0.5W, ensuring safety and efficiency.
5. Setup
5.1 Konnessjoni ta' Kelliema
Connect your passive speakers to the speaker output terminals on the rear panel. Ensure correct polarity (+ to + and - to -) for optimal sound quality. For stereo operation, connect the left speaker to the "Speaker Left Output" and the right speaker to the "Speaker Right Output".
5.2 Konnessjoni ta' Sorsi tal-Awdjo
Connect your audio source (e.g., DAC, CD player, pre-amplifier) to the PA400 using either the RCA Line Inputs (unbalanced) or the XLR Inputs (balanced). Use high-quality cables for the best audio performance.
5.3 Konnessjoni tal-Enerġija
Connect the supplied power cord to the AC IN (100V-240VAC) port on the rear panel and then to a suitable power outlet.
6. Istruzzjonijiet Operattivi
6.1 Power On/Off
Press the power button on the front panel or the remote control to turn the unit on or off. The Power LED will illuminate when the unit is on.
6.2 Kontroll tal-Volum
Rotate the Function Knob on the front panel or use the volume buttons on the remote control to adjust the output volume. The current volume level will be displayed on the screen.
6.3 Għażla tal-Input
Press the Function Knob or use the input selection buttons on the remote control to cycle through the available audio inputs (RCA, XLR, Mono In).
6.4 Navigazzjoni tal-Menu
Press and hold the Function Knob to enter the menu. Rotate the knob to navigate through menu options and press to confirm selections. Use the remote control for similar navigation.
7. Mono Bridge Mode Configuration
The S.M.S.L PA400 can operate in mono bridge mode, allowing two units to drive a single speaker each for increased power output. This configuration requires two PA400 units.

7.1 Steps for Mono Bridge Mode:
- Issettja AmpModalità lifier: On each PA400 unit, navigate through the menu to select "Mono" mode.
- Konnessjoni tal-Ispeaker: For each PA400, connect a single speaker to the "Mono Mode Speaker +" and "Mono Mode Speaker -" terminals. Ensure correct polarity.
- Konnessjoni tal-Input: Connect the mono signal from your pre-amplifier or source to the "Mono In (XLR)" input on each PA400 unit.
- Qawwa Mixgħul: Power on both PA400 units.
In mono bridge mode, each PA400 unit will deliver 500Wrms into an 8Ω load, providing substantial power for demanding speakers.
8. Manutenzjoni
- Tindif: Uża drapp ratba u niexfa biex tnaddaf il-barra tal- ampEvita li tuża prodotti tat-tindif jew solventi li joborxu.
- Ventilazzjoni: Ensure adequate ventilation around the unit. Do not block the side grilles, as they are essential for heat dissipation.
- Itfi: Always power off and unplug the unit before cleaning or making any connections.
