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. Benarkan 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 Mematikan Kuasa
