Prodott Overview
Kontrolli tal-Panew ta' Quddiem
Figure 1: Front panel of the Pro-Ject Phono Box DS3 B.
- Loading Ohms (Variable Potentiometer): Adjusts the input impedance for Moving Coil (MC) cartridges continuously from 10 to 1000 Ohms.
- Selettur tal-Input: Toggles between RCA and XLR input connections.
- Filtru Subsoniku: Activates a filter to remove very low-frequency rumble, improving sound clarity.
- Loading pF: Selects input capacitance for Moving Magnet (MM) cartridges (50, 150, 300, 400 pF).
- Żieda dB: Adjusts the gain level (40, 45, 50, 55, 60, 65 dB) to match your cartridge output and ampsensittività tad-dħul tal-lifer.

- Inputs (RCA & 5-pin mini XLR): Connect your turntable's output cables here. The 5-pin mini XLR allows for a true balanced connection from compatible turntables.
- Outputs (RCA & XLR): Qabbad dawn ma' tiegħek amplifier or receiver's line-level inputs. XLR outputs provide a balanced signal.
- Terminal tal-Art: Connect your turntable's ground wire here to minimize hum.
- Trigger Input/Output (12V): For remote power control with other compatible Pro-Ject components.
- Input ta' Enerġija DC 18V: Ikkonnettja l-adapter tal-enerġija fornut hawn.
Setup
Pjazzament
Place the Phono Box DS3 B on a stable, level surface, away from heat sources and other electronic devices that may cause interference. Ensure adequate ventilation around the unit.
Tqabbad it-turntable tiegħek
- Konnessjoni RCA: Connect the RCA cables from your turntable to the RCA inputs on the Phono Box DS3 B.
- Balanced Connection (5-pin mini XLR): If your turntable supports balanced output, connect a compatible 5-pin mini XLR cable from your turntable to the balanced input on the Phono Box DS3 B.
- L-ertjar: Connect the ground wire from your turntable to the ground terminal on the Phono Box DS3 B. This is crucial for minimizing hum and noise.
Konnessjoni ma' Tiegħek Ampaktar ħaj
- Output RCA: Connect RCA cables from the Phono Box DS3 B's RCA outputs to a line-level input (e.g., 'Aux', 'Line In', 'CD') on your amplifier jew riċevitur. Do not connect to a 'Phono' input on your ampaktar ħaj, as this would result in double pre-amplifikazzjoni.
- Ħruġ XLR: For a balanced connection, connect XLR cables from the Phono Box DS3 B's XLR outputs to balanced XLR inputs on your amplifier jew riċevitur.
Konnessjoni tal-Enerġija
Connect the supplied 18V DC power adapter to the 'Power 18V' input on the rear panel of the Phono Box DS3 B. Then, plug the power adapter into a suitable mains outlet. Uża biss l-adapter tal-enerġija li jiġi mal-unità.

Operazzjoni
Once all connections are made, you can power on the Phono Box DS3 B. The unit does not have a dedicated power switch; it powers on when connected to the mains. Adjust the settings on the front panel according to your cartridge type and listening preferences.
Għażla tal-Input
Use the 'Input' button to select between the RCA or XLR input, depending on how your turntable is connected.
Adjusting Load Impedance (MC Cartridges)
For Moving Coil (MC) cartridges, use the 'Loading Ohms' potentiometer to continuously adjust the input impedance. Experiment with different settings while listening to find the optimal sound for your specific MC cartridge. This adjustment can significantly impact the tonal balance and dynamics.
Adjusting Capacitance (MM Cartridges)
For Moving Magnet (MM) cartridges, use the 'Loading pF' buttons to select the appropriate input capacitance (50, 150, 300, or 400 pF). Refer to your cartridge manufacturer's recommendations for the ideal capacitance setting.
Aġġustament tal-Qligħ
Use the 'Gain dB' buttons to select the appropriate gain level (40, 45, 50, 55, 60, or 65 dB). This should be set to match the output voltage of your cartridge and the input sensitivity of your amplifier. Higher gain settings are typically used for low-output MC cartridges.
Bl-użu tal-Filtru Subsoniku
Press the 'Subsonic' button to activate the subsonic filter. This filter helps to remove very low-frequency noise and rumble (e.g., from warped records or turntable motor vibrations) that can cause woofer pumping and muddy bass without affecting the audible frequency range.
Manutenzjoni
The Pro-Ject Phono Box DS3 B requires minimal maintenance.
- Tindif: Uża drapp artab u niexef biex tnaddaf il-barra tal-unità. Tużax prodotti tat-tindif likwidi jew solventi, għax jistgħu jagħmlu ħsara lill-finitura.
- Ħażna: Jekk se taħżen l-unità għal perjodu estiż, skonnettjaha mill-provvista tal-enerġija u aħżenha f'post frisk u niexef.

| Problema | Kawża Possibbli | Soluzzjoni |
|---|---|---|
| L-ebda ħoss | Incorrect connections, wrong input selected, ampL-input tal-lifer mhux magħżul. | Check all cable connections. Ensure the correct input (RCA/XLR) is selected on the Phono Box DS3 B and the correct input is selected on your ampaktar ħaj. |
| Ħsejjes ta’ daqq jew żanżin | Grounding issue, proximity to other electronics, faulty cables. | Ensure the turntable's ground wire is securely connected to the Phono Box DS3 B. Move the unit away from other electronic devices. Try different cables. |
| Ħoss distort | Incorrect gain setting, incorrect loading (impedance/capacitance). | Adjust the 'Gain dB' setting. Verify 'Loading Ohms' (MC) or 'Loading pF' (MM) settings match your cartridge specifications. |
| Weak or low volume | Insufficient gain setting. | Increase the 'Gain dB' setting. |
