• EQ (Equalizer): Provides control over the high, mid (with sweepable frequency), and low frequencies to shape the tone of each channel.

• FX Send: Routes a portion of the channel signal to the internal effects processor.
• Pan: Positions the channel signal within the stereo field (left to right).
• Mute: Silences the channel output.
• Solo: Isolates the channel for monitoring through headphones or control room outputs without affecting the main mix.
