1. নিয়ন্ত্রণ লাভ: Adjust the GAIN knob for each channel to set the input level. Monitor the VU meter to ensure the signal is not clipping (entering the red zone).
2. টিউব ড্রাইভ: The TUBE DRIVE knob controls the amount of tube saturation. Turn clockwise for more warmth and harmonic richness, or counter-clockwise for a cleaner, more transparent sound.
3. ৪৮V ফ্যান্টম পাওয়ার: Press the 48V button to engage phantom power for condenser microphones. Ensure your microphone requires phantom power before activating.
4. -১০ ডিবি প্যাড: If your input source is very loud and causes clipping even with the GAIN knob at its minimum, press the PAD button to attenuate the input signal by 20 dB.
5. 80 Hz High-Pass Filter: Press the 80Hz button to activate a high-pass filter, which reduces low-frequency rumble and unwanted noise below 80 Hz.
6. Polarity Reverse: The Ø button reverses the polarity of the input signal. This can be useful for phase alignment when using multiple microphones.
7. VU মিটার: The illuminated analog VU meter provides a visual indication of your input signal level. Aim for the needle to stay within the green or yellow zones, avoiding the red (clipping) zone.
