4.3. Złącza panelu tylnego

Tył view of TEC TC-760LC Phono Preampżywsze

Image: Rear panel of the TEC TC-760LC Phono Preamplifier. Displays RCA output jacks, MM input jacks (47kΩ), MC input jacks (20Ω, 100Ω), a ground terminal, and the DC power input.

  • 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.
  • Terminal uziemiający: A screw terminal to connect your turntable's ground wire. This connection is crucial for minimizing hum and noise.
  • Wejście zasilania prądem stałym: A jack for connecting the included AC power adapter.

5. Konfiguracja

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

  1. Wyłącz wszystkie urządzenia: 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 PreampLiyfikator:
    • 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 Preamplżejszy do AmpLider/Odbiornik:
    • 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). Ważny: 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. Podłącz zasilacz: 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. Włączanie: First, power on your amplifier/receiver, then power on the TEC TC-760LC.

6. Instrukcja obsługi

Once the preampPo skonfigurowaniu lifiera należy wykonać następujące czynności:

  1. Wybierz wejście: Double-check that the MC/MM switch on the front panel is set to match your turntable's cartridge type (MM or MC).
  2. Dostosuj poziom: Start with the Level Control knob on the front panel at its minimum (lowest volume) setting.
  3. Odtwórz rekord: Place a record on your turntable and begin playback.
  4. Dostosuj głośność: 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.
