5. Kullanım Talimatları
This section details the operation of the LA-610 MKII's various sections.
5.1 Açma/Kapatma
Basın GÜÇ switch on the front panel to turn the unit ON. The indicator light will illuminate. Allow a few moments for the tubes to warm up before use. To power off, press the GÜÇ tekrar değiştir.
5.2 Öncesiamplifier Section (610 Tube Preamp)
- Giriş Seçimi: Ensure your input source is connected correctly (Mic, Line, or Hi-Z).
- Kazanç Kontrolü: Kullanın KAZANMAK knob to set the initial input gain. Common settings for vocals might be around -5dB, but adjust based on your microphone and source level.
