Section 1: Introduction- Detailed Description of Functions
AMPLIFIER MONITORING FUNCTIONS
Amplifier Model Detect- Identifies what model of QSC amplifier is connected to the CM16a’s DataPort.
Amplifier Gain Detect- Reports the setting of the amplifier’s gain setting (in dB) for each channel.
Bridge Mode Detect- Detects the position of the bridge mode switch on each amplifier.
Clip Detect- Detects amplifier clipping on each chan-
nel.
Headroom Metering- Reports the “available” re- maining signal level that the input signal can be driven before clipping will occur.
Heat Sink Temperature Metering- Monitors the heatsink temperature of each channel of each amplifier connected to the CM16a. If the temperature exceeds a user specified value (in software) then the
Load Monitor Detect- Monitors the impedance of the load at the amplifier output for each channel.
Output Current Meter- Provides for metering of the amplifier’s output current on each channel.
Output Voltage Meter- Provides for metering of the amplifier’s output voltage on each channel.
Output Open Detect- Detects when the load con- nected to the amplifier is above a user specified value in software.
Output Short Detect- Detects when the amplifier load is below a user specified value in software.
Power Status Detect- Reports AC power status of the amplifier (ON/standby/ OFF).
Protect Status Detect- Reports if the amplifier has entered “protect” mode (such as thermal,
Real Power Detect- Reports the “real” power the amplifier is delivering. This “real” power is not the same as “reactive” power.
Threshold Adjust- This indicates that the behavior of the associated block requires the input of a threshold value in software that must be crossed for the detection to occur. This allows the system operator to tailor the behavior of the system to each application.
PAGING FUNCTIONS
Input Sensitivity- Sets the sensitivity of the Page Input to either 1 Vrms or 3 Vrms. This selection should coincide with the level of the audio signal provided for the Page Input.
DAC- This is a
