Figura 4.1: Davant view of the Marshall SC20C Studio Classic Combo Amplificador. Aquesta imatge mostra el amplifier's black tolex covering, gold-colored control panel, and the iconic Marshall logo. The single 10-inch speaker is visible behind the grille cloth.

4.1 Controls del panell frontal

The front panel provides access to all primary sound-shaping controls.

  1. Jack d'entrada: Connect your guitar or other instrument here using a standard 1/4" instrument cable.
  2. Preamp Volum (Guany): Controls the amount of gain in the preamp section. Higher settings increase distortion and sustain.
  3. Volum mestre: Controla el volum de sortida general del ampmés viu.
  4. Aguts: Ajusta la resposta d'alta freqüència del ampmés viu.
  5. Mitjà: Ajusta la resposta de freqüència mitjana.
  6. Baix: Ajusta la resposta de baixa freqüència.
  7. Presència: Adds high-end sparkle and clarity by affecting the power amp's high-frequency response.
  8. Output Select (20W/5W): A switch to select between 20-watt and 5-watt output modes. The 5-watt mode provides earlier power amp saturation at lower volumes.
  9. Interruptor d'alimentació: Gira el ampmés viu encès o apagat.
  10. Interruptor d'espera: Engages or disengages the high voltage to the tubes. Always use the standby switch when warming up or cooling down the ampmés viu.

4.2 Connexions del panell posterior

The rear panel houses essential connections for power, external speakers, and effects loops.

  1. Entrada d'alimentació de CA: Connecteu aquí el cable d'alimentació subministrat.
  2. Sortides dels altaveus: Connect external speaker cabinets here. Ensure the impedance matches the amplifier's output (e.g., 8 Ohm, 16 Ohm). The internal speaker is typically connected to one of these.
  3. Effects Loop Send: Connect to the input of your external effects pedals.
  4. Effects Loop Return: Connect to the output of your external effects pedals.
  5. DI Output (XLR): Provides a balanced output for connecting directly to a mixing console or audio interface.

5. Configuració

Follow these steps to set up your Marshall SC20C ampmés viu:

  1. Col·locació: Col·loca el amplifier on a stable, level surface, ensuring adequate ventilation around the unit. Avoid placing it near heat sources or in direct sunlight.
  2. Connexió d'alimentació: Assegureu-vos el amplifier's power switch is in the OFF position and the standby switch is in the STANDBY position. Connect the supplied power cable to the AC Power Input on the rear panel and then to a grounded electrical outlet.
  3. Connexió de l'instrument: Connect your guitar to the Input Jack on the front panel using a high-quality instrument cable.
  4. Altaveu extern (opcional): If using an external speaker cabinet, ensure the internal speaker is disconnected (if applicable and specified in the manual, or ensure correct impedance matching if both are used). Connect the external speaker to the appropriate Speaker Output on the rear panel, matching the impedance. Always ensure a speaker load is connected before powering on.
  5. Bucle d'efectes (opcional): If using external effects, connect the "Send" of the amplifier to the input of your first effect pedal, and the output of your last effect pedal to the "Return" of the ampmés viu.

6. Instruccions de funcionament

Operating your SC20C amplifier involves a specific power-up and power-down sequence to protect the tubes and ensure longevity.

6.1 Encès

  1. Ensure all volume controls (Preamp Volume, Master Volume) are set to their minimum (zero) positions.
  2. Ensure the Standby switch is in the STANDBY position.
  3. Flip the Power switch to the ON position. The power indicator light will illuminate.
  4. Permet el amplifier to warm up for at least 30-60 seconds. This allows the tubes to reach their operating temperature.
  5. After the warm-up period, flip the Standby switch to the PLAY position.
  6. Slowly increase the Master Volume and Preamp Volume to your desired levels.

6.2 Apagat

  1. Reduce all volume controls (Preamp Volume, Master Volume) to their minimum (zero) positions.
  2. Flip the Standby switch to the STANDBY position.
  3. Permet el amplifier to cool down for a few seconds.
  4. Flip the Power switch to the OFF position. The power indicator light will extinguish.
  5. Unplug the power cable from the wall outlet if the ampno s'utilitzarà durant un període prolongat.

6.3 Tone Shaping

Experiment with the Preamp Volume, Master Volume, and EQ controls to achieve your desired sound. The Preamp Volume controls the amount of distortion, while the Master Volume controls the overall loudness. The Treble, Middle, and Bass controls allow you to sculpt the frequency response. The Presence control adds brightness and cut to your tone.

The Output Select switch allows you to choose between 20-watt and 5-watt operation. The 5-watt mode will allow the power tubes to saturate and compress at lower overall volumes, which can be ideal for practice or recording where full stage volume is not required.

7. Manteniment

Un manteniment adequat garantirà la longevitat i el rendiment òptim del vostre ampmés viu.

  • Neteja: Desconnecteu el amplifier from power before cleaning. Use a soft, dry cloth to wipe down the exterior. Do not use liquid cleaners or abrasive materials.
  • Cura del tub: Vacuum tubes have a finite lifespan and will eventually need replacement. Signs of worn tubes include reduced output, loss of tone, excessive noise, or microphonic feedback. Tube replacement should ideally be performed by a qualified technician. If replacing tubes yourself, ensure the amplifier is unplugged and allowed to cool completely, and handle tubes carefully.
  • Ventilació: Assegureu-vos el amplifier's ventilation openings are clear of obstructions at all times to prevent overheating.
  • Emmagatzematge: Quan no s’utilitzi, emmagatzemeu el fitxer amplifier in a dry, temperate environment, away from extreme temperatures or humidity.
