5. Орнотуу
5.1 Динамиктерди бириктирүү
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 Аудио булактарын туташтыруу
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 Кубат туташтыруу
Connect the supplied power cord to the AC IN (100V-240VAC) port on the rear panel and then to a suitable power outlet.
6. Иштөө нускамалары

7.1 Steps for Mono Bridge Mode:
- коюу Ampкөтөргүч режими: On each PA400 unit, navigate through the menu to select "Mono" mode.
- Динамик туташуу: For each PA400, connect a single speaker to the "Mono Mode Speaker +" and "Mono Mode Speaker -" terminals. Ensure correct polarity.
- Киргизүү байланышы: Connect the mono signal from your pre-amplifier or source to the "Mono In (XLR)" input on each PA400 unit.
- Күйгүзүү: 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.
