Алдыңкы панелдин башкаруу элементтери
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.
- Киргизүү тандагыч: Toggles between RCA and XLR input connections.
- Subsonic чыпкасы: Activates a filter to remove very low-frequency rumble, improving sound clarity.
- pF жүктөлүүдө: Selects input capacitance for Moving Magnet (MM) cartridges (50, 150, 300, 400 pF).
- ДБ алуу: Adjusts the gain level (40, 45, 50, 55, 60, 65 dB) to match your cartridge output and amplifier input sensitivity.

Figure 2: Rear panel connections of the Pro-Ject Phono Box DS3 B.
- 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): Буларды өзүңүзгө туташтырыңыз amplifier or receiver's line-level inputs. XLR outputs provide a balanced signal.
- Жер терминалы: Connect your turntable's ground wire here to minimize hum.
- Trigger Input/Output (12V): For remote power control with other compatible Pro-Ject components.
- 18V DC кубат киргизүү: Берилген кубат адаптерин бул жерге туташтырыңыз.
Жайгашуу
Жайгаштыруу
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.
Айлануучу табакты туташтыруу
- RCA туташуу: 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.
- Негиздөө: 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.
Сиздин Ampөмүрлүү
- RCA чыгаруу: 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 ampкөтөргүч же кабыл алгыч. Do not connect to a 'Phono' input on your ampөмүрлүү, анткени бул эки эсе алдын алаampжашоо.
- XLR чыгаруу: For a balanced connection, connect XLR cables from the Phono Box DS3 B's XLR outputs to balanced XLR inputs on your ampкөтөргүч же кабыл алгыч.
Power Connection
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. Бирдик менен берилген кубат адаптерин гана колдонуңуз.

Иштеп жатат
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.
Киргизүүнү тандоо
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.
Пайданы тууралоо
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.
Subsonic чыпкасын колдонуу
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.
Техникалык тейлөө
The Pro-Ject Phono Box DS3 B requires minimal maintenance.
- Тазалоо: Use a soft, dry cloth to clean the exterior of the unit. Do not use liquid cleaners or solvents, as they may damage the finish.
- Сактагыч: Агрегатты узак убакытка сактасаңыз, аны кубаттан ажыратып, салкын, кургак жерде сактаңыз.
