3. Настройка
3.1 Распаковка и размещение
Carefully remove the record player and all accessories from the packaging. Place the unit on a sturdy, level surface to prevent vibrations from affecting playback quality. Ensure there is enough space around the unit for the dust cover to open fully.
3.2 Установка пластины
- Gently place the turntable platter onto the spindle.
- Place the felt mat or rubber mat on top of the platter.
3.3 Установка пылезащитного чехла
Attach the dust cover hinges to the designated slots on the rear of the record player cabinet. Carefully lower the dust cover onto the hinges.
3.4 Регулировка баланса тонарма и прижимной силы
- Ensure the cartridge is securely mounted to the headshell.
- Lower the tonearm lifter. Release the tonearm clamp.
- Поворачивайте противовес в задней части тонарма до тех пор, пока тонарм не будет идеально сбалансирован (не будет плавать в горизонтальном положении).
- Once balanced, hold the counterweight steady and rotate only the tracking force ring until '0' aligns with the center line on the tonearm.
- Rotate the entire counterweight (including the ring) to set the recommended tracking force for your cartridge (e.g., 1.5g to 2.0g). Refer to your cartridge's specifications.
3.5 Регулировка антискейтинга
Set the anti-skating dial to match the tracking force you have set. This compensates for the inward force on the stylus as the record plays.
3.6 Аудиоподключения
- Connect the RCA audio cables from the record player's output to the 'PHONO' input on your ampприемник или передатчик.
- Connect the ground wire from the record player to the 'GND' terminal on your amplifier or receiver. This helps reduce hum.
3.7 Подключение питания
Plug the power cord into an appropriate AC 100V wall outlet.
