• АШИГ: Adjusts the input sensitivity for the connected device. Use this to achieve a healthy signal level without clipping.
• EQ (эквалайзер): The mono channel (Mic/Line 1) has a 2-band EQ (HIGH and LOW) to shape the tone of the input signal.
• ПАН/БАЛ: The PAN control (mono channel) adjusts the signal's position in the stereo field (left to right). The BAL (balance) control (stereo channels) adjusts the relative level of the left and right signals.
• ТҮВШИН: Controls the overall output level of the individual channel to the main mix.
• CLIP LED: Оролтын дохио хэт өндөр байх үед гэрэлтдэг бөгөөд энэ нь гажуудал үүсэх магадлалыг илтгэнэ. Хэрэв энэ LED байнга асдаг бол GAIN-г бууруулна уу.
