- 접지 터미널: Connects to the ground wire from your turntable to minimize hum.
- In (RCA): Audio input from your turntable (Left and Right channels).
- Subsonic Button: Activates or deactivates the subsonic filter, which removes very low-frequency rumble.
- Out (RCA): Audio output to your amplifier or receiver (Left and Right channels).
- 18V DC 전원 입력: 제공된 18V DC 전원 어댑터에 연결합니다.
5. 설정
Follow these steps to properly set up your Pro-Ject Phono Box S2.
5.1. 연결
- Ensure all audio components are turned off before making connections.
- 턴테이블의 RCA 출력 케이블을 연결하세요. 'In' RCA jacks on the rear of the Phono Box S2. Ensure left and right channels are correctly matched.
- 턴테이블의 접지선을 다음에 연결하세요. 접지 단자 on the Phono Box S2. This helps reduce hum.
- 연결하다 'Out' RCA jacks of the Phono Box S2 to a line-level input on your amplifier or receiver (e.g., CD, Aux, Line In). Do not connect to a phono input on your amplifier, as this will result in distorted sound.
- Connect the supplied 18V DC power supply to the '18V DC' input on the rear of the Phono Box S2, then plug the power supply into a wall outlet.

5.2. DIP Switch Settings (Bottom Panel)
The Phono Box S2 features DIP switches on its underside, allowing you to adjust gain, input impedance, and input capacitance to match your specific phono cartridge. There are two sets of switches, one for the left channel and one for the right. Ensure both sets are configured identically.
Refer to your cartridge's specifications for recommended settings. If you are unsure, consult your cartridge manufacturer's documentation or an audio specialist.
| 환경 | 설명 | Common Values / Purpose |
|---|---|---|
| 이득 (dB) | 조정합니다 amp합리화 수준. | 40dB: Standard for Moving Magnet (MM) cartridges. 43dB: Slightly higher gain for MM, or some high-output MC. 60dB: Standard for Moving Coil (MC) cartridges. 63dB: Slightly higher gain for MC. |
| Input Impedance (Ohms) | Sets the electrical load presented to the cartridge. | 47k Ohms: Standard for MM cartridges. 10/100/1k/2k Ohms: For MC cartridges, match to cartridge recommendation. |
| 입력 커패시턴스(pF) | Sets the electrical capacitance presented to the cartridge. | 100pF/200pF/320pF/420pF: Primarily for MM cartridges. Match to cartridge recommendation, often combined with tonearm cable capacitance. |
메모: Always power off the Phono Box S2 and disconnect the power supply before changing DIP switch settings to avoid potential damage or unexpected behavior.
6. 운영
Once all connections are made and DIP switches are set, operating the Phono Box S2 is straightforward.
- Press the power button on the front panel to turn on the Phono Box S2. The power LED will illuminate.
