Opsætning

1. Udpakning og inspektion

Fjern forsigtigt amplifier from its packaging. Inspect the unit for any signs of damage. Ensure all components are present.

2. Strømtilslutning

The UB-30 can be powered by either AC mains or a 12V DC battery.

1. AC Mains (220-240V): Connect the provided AC power cord to the AC power input on the rear panel and then to a suitable wall outlet.
2. DC Battery (12V): For portable use, connect a 12V car battery to the DC input terminals on the rear panel. Ensure correct polarity: positive (+) to positive, negative (-) to negative.

Forsigtighed: Sørg altid for amplifier is switched OFF before connecting or disconnecting power sources.

3. Højttalerforbindelse

Connect your speakers to the appropriate terminals on the rear panel. Match the speaker impedance to the amplifier's output impedance for optimal performance and to prevent damage.

1. Connect the common (negative) terminal of your speaker(s) to the KOM terminal på amplivligere.
2. Connect the positive terminal of your speaker(s) to the 4Ω, 8Ω, eller 16Ω terminal, matching your speaker's impedance.
3. For 100V line speakers, connect to the 100V terminal og KOM. Ensure your speakers are compatible with 100V line systems.

Vigtig: Do not connect speakers to multiple impedance terminals simultaneously. Ensure all connections are secure.

4. Input Device Connection

1. Mikrofoner: Tilslut mikrofoner til MIC-1 og/eller MIC-2/AUX 6.3mm input jacks on the front panel.
2. Hjælpeenheder: Connect audio sources like smartphones, CD players, or laptops to the MIC-2/AUX input jack using an appropriate cable.

Betjeningsvejledning

1. Tænder

1. Ensure all volume controls (MIC-1, MIC-2/AUX) are set to their minimum position (fully counter-clockwise).
2. Tryk på MAGT switch on the front panel to the 'ON' position. The power indicator light will illuminate.

2. Justering af lydstyrke

1. For MIC-1, slowly turn the MIC-1 lydstyrkekontrol clockwise until the desired sound level is achieved.
2. For MIC-2 or AUX input, slowly turn the MIC-2/AUX Volume Control clockwise until the desired sound level is achieved.
3. Avoid setting the volume too high, which can cause distortion or damage to speakers.

3. Tonejustering

Brug TONE kontrol knob to adjust the frequency response of the amplifier. Turning it towards 'CUT' will reduce higher frequencies (treble), while turning it towards 'FLAT' will provide a more balanced, full-range sound.

4. Sluk

1. Turn all volume controls to their minimum position.
2. Tryk på MAGT switch to the 'OFF' position. The power indicator light will turn off.

Opretholdelse

Rensning

Tør det ydre af ampmed en blød, tør klud. Brug ikke flydende rengøringsmidler eller slibende materialer, da de kan beskadige overfladen eller de indvendige komponenter.

Fuse Replacement (DC Fuse)

Hvis amplifier fails to power on when using DC battery power, the DC fuse may need replacement. The fuse is located on the rear panel.

1. Vigtig: Disconnect all power sources (AC and DC) before attempting to replace the fuse.
2. Unscrew the fuse holder cap on the rear panel.
3. Remove the old fuse and replace it with a new fuse of the same type and rating (T 6A L).
4. Securely screw the fuse holder cap back into place.

Forsigtighed: Always replace fuses with the specified type and rating to prevent damage to the amplifier or risk of fire.
