- For balanced sources, connect XLR cables from your source to the H400's Balancerede indgange (XLR).
- For unbalanced sources, connect RCA cables from your source to the H400's Unbalanced Inputs (RCA).
- Tilslut hovedtelefoner: Tilslut dine hovedtelefoner til enten Balanceret 4-bens XLR or Unbalanced 6.35mm headphone output on the front panel.
- Tilslut til strøm Ampafdækning (valgfrit): If using the H400 as a preamplifier, tilslut Balanced Pre-Outputs (XLR) or Unbalanced Pre-Outputs (RCA) to your power amplifier eller aktive højttalere.
- Strømtilslutning: Connect the included power cable to the Vekselstrømsindgang on the rear panel, then plug the other end into a suitable AC power outlet (100-240V).
- Tænd: Vend Strømafbryder on the rear panel to the 'ON' position. The unit will power on, and the display will illuminate.
Betjeningsvejledning
Grundlæggende betjening
- Tænd/sluk: Use the rear panel switch for main power. The remote control can put the unit into standby.
- Lydstyrkekontrol: Drej på Volumenknap on the front panel or use the volume buttons on the remote control to adjust the output level.
- Valg af input: Tryk på Volumenknap briefly to cycle through available input sources (Balanced, Unbalanced). Alternatively, use the input selection buttons on the remote.
- Forstærkningsindstilling: The H400 offers High, Medium, and Low gain settings. These can be adjusted via the menu system, typically accessed by pressing and holding the volume knob or a dedicated button on the remote.
- Balanced Gain: Low (-5.8dB), Medium (6dB), High (20.4dB)
- Unbalanced Gain: Low (-11.8dB), Medium (0dB), High (14.4dB)
Fjernbetjening
The included remote control provides convenient access to all functions, including power, volume, input selection, and menu navigation. Ensure the remote has fresh batteries and an unobstructed line of sight to the H400's front panel sensor.
Opretholdelse
- Rensning: Brug en blød, tør klud til at rengøre enhedens yderside. Brug ikke flydende rengøringsmidler eller opløsningsmidler.
