• تبديل كتم الصوت: Silences the channel's output.
• PFL (Pre-Fader Listen) Switch: Routes the channel's signal to the headphone output for monitoring before the fader.
• Peak Level Indicator: يضيء عندما تكون إشارة الإدخال عالية جدًا، مما يشير إلى احتمال حدوث تشويه.
• 60mm Volume Fader: Adjusts the overall output level of the channel.

3.2 Stereo Channel Controls (Channels 5/6)

• 3 نطاقات المعادل: Adjusts high, mid, and low frequencies for the stereo input.
• Aux Sends (1-4): Controls the level of the channel's signal sent to the four auxiliary outputs. Aux 1 and 2 can be switched between pre-fader and post-fader.
• التحكم في التوازن: Adjusts the relative level between the left and right signals of the stereo channel.
• تبديل كتم الصوت: Silences the channel's output.
• PFL (Pre-Fader Listen) Switch: Routes the channel's signal to the headphone output for monitoring before the fader.
• Peak Level Indicator: Illuminates when the input signal is too high.
• 60mm Volume Fader: Adjusts the overall output level of the stereo channel.

3.3 Dual Stereo Multi-Effects Processor

The MC-R8FX features two independent stereo multi-effects processors, each offering 205 high-quality programs. These processors are based on a 56-bit internal DSP with 24-bit conversion, providing versatile and clear effects for your audio.
