- Loading Ohms (Variable Potentiometer): Adjusts the input impedance for Moving Coil (MC) cartridges continuously from 10 to 1000 Ohms.
- Pamilih Input: Toggles between RCA and XLR input connections.
- Saringan Subsonik: Activates a filter to remove very low-frequency rumble, improving sound clarity.
- Ngamuat pF: Selects input capacitance for Moving Magnet (MM) cartridges (50, 150, 300, 400 pF).
- Keuntungan dB: Adjusts the gain level (40, 45, 50, 55, 60, 65 dB) to match your cartridge output and ampsensitipitas input liifier.

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.
Nyambungkeun Turntable Anjeun
- Sambungan 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.
- Grounding: 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.
Nyambung ka Anjeun Amppangagung
- Kaluaran 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 atawa panarima. Do not connect to a 'Phono' input on your amppangagung, as this would result in double pre-amplifikasi.
- Kaluaran XLR: For a balanced connection, connect XLR cables from the Phono Box DS3 B's XLR outputs to balanced XLR inputs on your amplifier atawa panarima.
Sambungan Daya
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. Ngan anggo adaptor daya anu disayogikeun sareng unit ieu.

Ngoperasikeun
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.
Pilihan 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.
Nyaluyukeun Gain
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.
Ngagunakeun Subsonic Filter
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.
