4. Opsætning
4.1 Placering
Place the CAD-300SEI on a stable, level surface away from direct sunlight, heat sources, and excessive moisture. Ensure there is ample ventilation around the unit, especially above the vacuum tubes, to prevent overheating. Do not place the amplifier in an enclosed cabinet without proper airflow.
4.2 Tube Installation (if not pre-installed)
If the vacuum tubes are not pre-installed, carefully insert them into their respective sockets. The 300B output tubes are larger and typically go into the rear sockets, while the 6SN7 input and driver tubes go into the front sockets. Ensure correct orientation and gently push each tube firmly into its socket until seated. Avoid touching the glass of the tubes with bare hands, as oils can shorten their lifespan.
4.3 Tilslutning af lydkilder
The CAD-300SEI features three RCA stereo inputs. Connect your audio source components (e.g., CD player, streamer, phono preamplifier) to the desired RCA input jacks on the rear panel using high-quality RCA cables. Ensure left and right channels are correctly matched.
- Indgang 1: For primary source.
- Indgang 2: For secondary source.
- Indgang 3: For tertiary source.
4.4 Tilslutning af højttalere
Connect your loudspeakers to the speaker binding posts on the rear panel. Ensure proper polarity: connect the positive (+) terminal of the amptil den positive (+) terminal på højttaleren, og den negative (-) terminal på amplifier to the negative (-) terminal of the speaker. Use high-quality speaker cables. The CAD-300SEI is designed for moderate to high efficiency speakers.
4.5 Strømtilslutning
Before connecting the power cable, ensure all other connections are secure and the amplifier's volume control is set to minimum. Connect the supplied power cable to the AC inlet on the rear panel of the amplifier, then plug the other end into a suitable AC wall outlet. It is recommended to use a dedicated power line or a high-quality power conditioner for optimal performance.
5. Betjeningsvejledning
5.1 Tænd/sluk
- Ensure all connections are correct and the volume knob is at its minimum setting.
- Press the power switch located on the front panel. The indicator light will illuminate.
