6. Instruksi Operasi

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

6.1 Daya Ngaktifake

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. Izin kan 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 Pateni daya

1. Reduce all volume controls (Preamp Volume, Master Volume) to their minimum (zero) positions.
2. Flip the Standby switch to the STANDBY position.
3. Izin kan 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 amplifier ora bakal digunakake kanggo wektu lengkap.

6.3 Tone Shaping

Experiment with the Preamp Volume, Master Volume, and EQ controls to achieve your desired sound.
