Follow these steps to set up your Schiit Mani 2 Phono Preampజీవితకాలం:

1. అన్‌ప్యాక్: Carefully remove the Mani 2 and its power adapter from the packaging.
2. ప్లేస్‌మెంట్: Position the Mani 2 near your turntable and audio receiver/amplifier. Ensure there is enough space for cable connections and ventilation.
3. Adjust Dip Switches (Bottom Panel): Before connecting, configure the gain, loading, and low-frequency filter settings using the dip switches located on the bottom of the unit. Refer to Section 6.1 for detailed instructions on these adjustments.
4. Connect Turntable: Connect the RCA output cables from your turntable to the "IN" RCA jacks on the rear panel of the Mani 2. Ensure left (L) and right (R) channels are correctly matched.
5. గ్రౌండ్ వైర్ కనెక్ట్ చేయండి: Connect the ground wire from your turntable to the ground terminal on the rear panel of the Mani 2. This helps reduce hum and noise.
6. కనెక్ట్ చేయండి Ampజీవితకాలం: Connect the "OUT" RCA jacks on the rear panel of the Mani 2 to a line-level input (e.g., "AUX", "CD", "Tuner") on your audio receiver or ampజీవితకాలం. Do not connect to your amplifier's "PHONO" input, as this would result in double pre-ampలిఫికేషన్.
7. పవర్ కనెక్ట్ చేయండి: Connect the provided power adapter to the "AC IN" jack on the rear panel of the Mani 2, then plug the adapter into a suitable 115VAC wall outlet.
8. పవర్ ఆన్: Flip the power switch on the rear panel to the "ON" position. The front panel LED will illuminate.

Once the Mani 2 is set up and connected, operating it is straightforward. The primary adjustments are made via the dip switches on the bottom panel.

6.1. Adjusting Gain, Loading, and LF Filter

The Mani 2 offers significant flexibility to match various cartridges. These settings are configured using dip switches on the bottom of the unit. Always power off the Mani 2 and disconnect the power adapter before making any adjustments to the dip switches.

సెట్టింగులను పొందండి

Gain adjusts the amplification level to match your cartridge's output. Refer to your cartridge's specifications for recommended gain. The Mani 2 offers four gain settings:

• 35dB: Suitable for high-output MM/MI cartridges.
• 45dB: Common for standard MM/MI cartridges.
• 50dB: For lower-output MM/MI or higher-output MC cartridges.
• 60dB: Ideal for low-output MC cartridges.

Consult Figure 2 for the location of the gain dip switches and their corresponding positions for each setting.

Loading Settings (Resistance and Capacitance)

Loading refers to the electrical impedance presented to the cartridge. Correct loading optimizes frequency response and transient behavior. The Mani 2 provides options for both resistive and capacitive loading.

• Resistive Loading: Choose from 47KΩ (standard for MM/MI), 200Ω, 47Ω, or 38Ω (for MC cartridges).
• Capacitive Loading: Choose from 47pF, 100pF, 150pF, or 200pF.

The default setting for MM/MI cartridges is typically 47KΩ and 47pF. For MC cartridges, consult the cartridge manufacturer's recommendations. Consult Figure 2 for the location of the loading dip switches and their corresponding positions for each setting.

Low-Frequency (LF) Filter

The LF filter helps mitigate issues caused by warped records or turntable rumble, which can cause excessive woofer excursion. The Mani 2 offers two passive filter options at 15 Hz:

• 6dB/octave: A gentler filter.
• 12dB/octave: A steeper filter for more pronounced issues.

If you experience excessive woofer movement or low-frequency distortion, engaging the LF filter may be beneficial. Consult Figure 2 for the location of the filter dip switches.

6.2. సాధారణ ఆపరేషన్

Once all connections and dip switch settings are confirmed:

1. మీ నిర్ధారించుకోండి amplifier/receiver is turned off or its volume is set to minimum.
2. Turn on the Mani 2 using the rear power switch. The front LED will light up.
3. మీ ఆన్ చేయండి amplifier/receiver and select the input connected to the Mani 2.
4. Start playing a record on your turntable.
5. మీ పరికరంలో వాల్యూమ్‌ను నెమ్మదిగా పెంచండి amplifier/receiver to your desired listening level.
