- Ensure all audio components are turned off before making connections.
- So awọn okun okùn RCA lati inu tabili turntable rẹ pọ mọ '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 ilẹ ebute on the Phono Box S2. This helps reduce hum.
- Sopọ awọn '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.
| Eto | Apejuwe | Common Values / Purpose |
|---|---|---|
| Ere (dB) | Ṣe atunṣe awọn ampipele lification. | 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. |
| Agbara titẹ sii (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. |
Akiyesi: Always power off the Phono Box S2 and disconnect the power supply before changing DIP switch settings to avoid potential damage or unexpected behavior.

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.
- Tan-an rẹ 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 ampolùgbàlejò/olùgbàlejò sí ìpele ìgbọ́ran tí o fẹ́.
- To turn off the unit, press the power button again. The power LED will extinguish.
Subsonic Ajọ
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.

If you encounter issues with your Phono Box S2, refer to the following common problems and solutions.
| Isoro | Owun to le Fa | Ojutu |
|---|---|---|
| No sound or very low sound output. | Incorrect connections; Phono Box S2 not powered on; Amplifier input not selected; Incorrect gain setting. | Check all RCA and power connections. Ensure Phono Box S2 is powered on. Select the correct line-level input on your amplifier. Verify DIP switch gain settings match your cartridge. |
| Distorted or harsh sound. | Ti sopọ si amplifier's phono input; Incorrect gain setting (too high); Incorrect impedance/capacitance. | Connect Phono Box S2 to a line-level input (CD, Aux) on your amplifier. Adjust DIP switch gain to a lower setting. Verify impedance and capacitance settings match your cartridge. |
| Ariwo ìró tàbí ariwo ìró. | Ground wire not connected; Ground loop; Nearby electrical interference. | Ensure turntable ground wire is securely connected to the Phono Box S2 ground terminal. Try connecting the Phono Box S2 and amplifier to the same power strip. Move the unit away from other electronic devices. |
| Sound is dull or lacking detail. | Incorrect impedance or capacitance setting. | Adjust DIP switch impedance and capacitance settings to better match your cartridge's specifications. |
