  • OUTPUT (Receiver/Amp): RCA stereo output jacks (Left and Right) for connecting to your amplifier or receiver's line-level input (e.g., AUX, CD, Tuner).
  • INPUTS (MM): RCA stereo input jacks (Left and Right) specifically for Moving Magnet cartridges. The input impedance is fixed at 47kΩ.
  • INPUTS (MC): RCA stereo input jacks (Left and Right) for Moving Coil cartridges. These inputs feature selectable impedance options: 20Ω and 100Ω, typically chosen via small switches near the inputs.
  • Уземљени терминал: A screw terminal to connect your turntable's ground wire. This connection is crucial for minimizing hum and noise.
  • Улаз за једносмерну струју: A jack for connecting the included AC power adapter.

5. Подешавање

Follow these steps to correctly set up your TEC TC-760LC Phono Preampдизалица:

  1. Power Off All Equipment: Before making any connections, ensure your turntable, amplifier/receiver, and the phono preamplifier are all powered off and unplugged from the wall outlet.
  2. Connect Turntable to Preampдизалица:
    • Connect the RCA output cables from your turntable to the appropriate INPUTS on the TEC TC-760LC (MM or MC, depending on your cartridge type).
    • Connect the ground wire from your turntable to the Ground terminal on the preamplifier. Secure the connection by tightening the screw.
  3. Connect Preampлифиер то AmpЛифиер/Рецеивер:
    • Connect the RCA output cables from the TEC TC-760LC's OUTPUT jacks to a line-level input on your amplifier or receiver (e.g., AUX, CD, Tuner). Важно: Do NOT connect to your amplifier's dedicated PHONO input, as this unit is already a phono preamplifier and connecting to another phono input will result in distorted sound.
  4. Повежите адаптер за напајање: Plug the small barrel connector of the included AC power adapter into the DC Power Input on the rear of the preamplifier. Then, plug the AC power adapter into a suitable wall outlet.
  5. Select Cartridge Type and Impedance: Use the MC/MM Select switch on the front panel to match your turntable's cartridge type. For Moving Coil cartridges, ensure the correct impedance (20Ω or 100Ω) is selected via the small switches located near the MC input jacks on the rear panel. Consult your MC cartridge's specifications for the recommended impedance.
  6. Укључено: First, power on your amplifier/receiver, then power on the TEC TC-760LC.

6. Упутство за употребу

Once the preampКада је спасилац подешен, пратите ове кораке за рад:

  1. Изаберите унос: Double-check that the MC/MM switch on the front panel is set to match your turntable's cartridge type (MM or MC).
  2. Adjust Level: Start with the Level Control knob on the front panel at its minimum (lowest volume) setting.
  3. Play Record: Place a record on your turntable and begin playback.
  4. Подесите јачину звука: Slowly increase the Level Control on the TEC TC-760LC and the main volume on your amplifier/receiver to achieve the desired listening level. Avoid setting the Level Control too high, which can lead to distortion.
