Prednja ploča
The front panel of the Phono Box S2 features a minimalist design with a single control element.
Slika 1: Prednja strana view of the Pro-Ject Phono Box S2 in black. The front panel features a circular power button on the left side, with a small LED indicator above it. The 'P Phono Box S2' logo is printed below the button.
- Gumb za napajanje: Koristi se za uključivanje ili isključivanje jedinice.
- LED za napajanje: Svijetli kada je jedinica uključena.
Stražnja ploča
The rear panel provides all necessary connections for your turntable and amplifier, along with the power input.
Slika 2: Stražnji dio view of the Pro-Ject Phono Box S2. From left to right, it shows a ground screw terminal, 'In' RCA jacks (Left and Right), a 'Subsonic' button, 'Out' RCA jacks (Left and Right), and the 18V power input jack.
- Uzemljeni terminal: 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 ulaz napajanja: Connects to the supplied 18V DC power adapter.
5. Postavljanje
Follow these steps to properly set up your Pro-Ject Phono Box S2.
5.1. Veze
- Ensure all audio components are turned off before making connections.
- Spojite RCA izlazne kabele s gramofona na 'In' RCA jacks on the rear of the Phono Box S2. Ensure left and right channels are correctly matched.
- Connect the ground wire from your turntable to the terminal za uzemljenje on the Phono Box S2. This helps reduce hum.
- Spojite '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.
| Postavka | Opis | Common Values / Purpose |
|---|---|---|
| Dobitak (dB) | Podešava amprazina lifikacije. | 40 dB: Standard for Moving Magnet (MM) cartridges. 43 dB: Slightly higher gain for MM, or some high-output MC. 60 dB: Standard for Moving Coil (MC) cartridges. 63 dB: 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. |
| Ulazni kapacitet (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. |
Bilješka: 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. Operacija
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.
- Uključi svoj amplifier/receiver and select the input to which the Phono Box S2 is connected.
- Start playing a record on your turntable. Adjust the volume on your ampprijemnik/aparat na željenu razinu slušanja.
- To turn off the unit, press the power button again. The power LED will extinguish.
Podzvučni filtar
The subsonic filter button on the rear panel can be used to remove very low-frequency rumble that can be generated by warped records or turntable motor vibrations. This can improve sound clarity and prevent unnecessary strain on your amplifier and speakers. Press the button to toggle the filter on or off.
