Návod k obsluze
1. Zapnutí/vypnutí

2. Ovládání hlasitosti
The large "VOLUME" knob on the right side of the front panel controls the overall audio output level. Rotate clockwise to increase volume and counter-clockwise to decrease it. Start with the volume at a low setting before playing audio to prevent sudden loud sounds.
3. Tone Controls (Treble and Bass)
The "TREBLE" and "BASS" knobs allow you to adjust the high and low frequencies of the audio output, respectively. Rotate clockwise to boost the frequency and counter-clockwise to cut it. Adjust these to your preference for balanced sound.
4. Tone/Direct Switch
The "TONE / DIRECT" switch bypasses the treble and bass tone controls when set to "DIRECT". In "DIRECT" mode, the audio signal passes through the amplifier without any equalization, providing a pure, uncolored sound. In "TONE" mode, the treble and bass controls are active.
Údržba
- Čištění: K čištění používejte měkký, suchý hadřík amplifier's exterior. Do not use liquid cleaners or aerosols, as they may damage the finish or internal components.
