• Gain - Globally set for all channels, from +23dB to +44 dB in 3dB steps.
• Option active - Not currently implemented.
• Fan Masked - When on, engages the intelligent fan feature; fan speed is lowered when no signal is
present.
• Bridge A+B and C+D - Switches the channel pairs into bridge mode operation An automatic - 6dB gain
compensation is applied.
• VL - The Voltage Limiter provides optimum peak voltage settings for each channel . Eight discrete levels
are selectable.
• Mode - Select VL mode to either Hard or Soft operation. For channels driving sub-woofers and low-
frequency drivers, it is recommended to use the hard setting for optimal operation. For mid- and high-
frequency drivers, always select Soft.
