2. Opsætning
2.1 Udpakning
Fjern forsigtigt amplifier from its packaging. Check for any signs of damage during transit. Keep the original packaging for potential future transport or servicing.
2.2 Placering
Placer amplifier on a stable, level surface away from direct sunlight, heat sources, and excessive dust or vibration. Ensure there is sufficient clearance (at least 10 cm or 4 inches) around the top and sides for proper heat dissipation.
2.3 Forbindelser
Før du foretager nogen tilslutninger, skal du sørge for, at amplifier and all connected components are powered off and unplugged from the AC outlet.
- Højttalerforbindelser: Connect your speakers to the SPEAKER A or SPEAKER B terminals on the rear panel. Ensure correct polarity (+ to + and - to -) for each speaker. Use high-quality speaker cables.
- Lydkildeforbindelser: Connect your audio sources (e.g., CD player, tuner, turntable, tape deck) to the corresponding input jacks (CD, TUNER, PHONO, TAPE 1, TAPE 2) on the rear panel using RCA audio cables.
- Ground Terminal (PHONO): If connecting a turntable, connect its ground wire to the PHONO GROUND terminal to minimize hum.
- Strømtilslutning: Når alle lyd- og højttalertilslutninger er foretaget, skal du tilslutte amplifier's power cord into a suitable AC wall outlet.
3. Betjeningsvejledning
3.1 Grundlæggende betjening
- Tænd/sluk: Tryk på POWER-knappen på frontpanelet for at tænde amplivligere til eller fra.
- Valg af input: Use the INPUT SELECTOR knob or buttons to choose the desired audio source (e.g., CD, TUNER, PHONO).
- Lydstyrkekontrol: Adjust the VOLUME knob to set the listening level. Start at a low volume and gradually increase it.
- Valg af højttaler: If you have two pairs of speakers connected, use the SPEAKER A/B selector to choose which pair to use, or both.
3.2 Tonekontroller
De amplifier features tone controls to adjust the sound characteristics:
- BAS: Adjusts the low-frequency response. Turn clockwise for more bass, counter-clockwise for less.
- DISKANT: Adjusts the high-frequency response. Turn clockwise for more treble, counter-clockwise for less.
- BALANCE: Justerer den relative lydstyrke mellem venstre og højre kanal.
- HØJHED: Engages a circuit that boosts bass and treble at low volume levels for a fuller sound.
- SOURCE DIRECT: Bypasses the tone control circuits for a purer audio signal.
3.3 Recording Functions (PMA-915R/715R)
De amplifier allows for recording from one source to a tape deck connected to the TAPE 1 or TAPE 2 REC OUT jacks. Use the REC OUT SELECTOR to choose the source you wish to record, independent of the source being listened to.
4. Vedligeholdelse
4.1 Rengøring
For at rense amplifier, first disconnect it from the power outlet. Use a soft, dry cloth to wipe the exterior surfaces. Do not use abrasive cleaners, waxes, or solvents as they may damage the finish.
4.2 Opbevaring
If storing the unit for an extended period, unplug it from the power outlet and cover it to protect against dust. Store in a cool, dry place.
5. Fejlfinding
Hvis du oplever problemer med din amplifier, refer to the following table before contacting service personnel.
| Problem | Mulig årsag | Løsning |
|---|---|---|
| Ingen strøm | Power cord not connected; Power switch off; Blown fuse | Check power cord connection; Turn power switch on; Consult service personnel for fuse replacement. |
| Ingen lyd | Incorrect input selected; Speaker cables disconnected; Volume too low; Mute engaged | Select correct input; Check speaker connections; Increase volume; Disengage mute. |
| Forvrænget lyd | Input level too high; Speaker impedance mismatch; Damaged speaker cables | Reducer kildens lydstyrke; Sørg for, at højttalerne passer sammen amplifier impedance; Check/replace speaker cables. |
| Brummende støj | Ground loop; Improper cable shielding; Turntable ground not connected | Ensure all components are properly grounded; Use shielded cables; Connect turntable ground wire. |
