[. . . ] The numerical value below the fader is the current attenuation setting in dB. Attenuation can also be set by clicking the Up and Down arrow buttons, or by entering a value from the keyboard. Phase button: This button is used to set the channel's input signal phase: Normal or Reversed. Mute button: This button is used to mute the channel. Output meter: This 12-segment meter displays the channel's output level in either watts of volts (see preference on page 8). The Present value is the current output level. The yellow triangle indicates the warning threshold specified on the Threshold page (see page 24). Input meter: This 12-segment meter displays the channel's input level in dB. The Present value is the current input level. Temperature: This 12-segment meter displays the channel's temperature in either centigrade or Fahrenheit (see preference on page 8). The Present value is the current temperature. The maximum temperature is displayed graphically by the green triangle at the right of the meter, and numerically by the Max hold value. To reset the max hold, right-click the meter and choose "Reset temp hold on this channel" or "Reset temp hold on all channels" from the pop-up menu. Load impedance: This is the channel's load impedance. The Present value is the current load impedance. NetworkAmp Manager--Owner's Manual Threshold Page 24 Threshold Page This page is used to specify the wattage, temperature, and the minimum and maximum load impedance thresholds at which you want NetworkAmp Manager to issue a warning. The thresholds can be set individually for each power amplifier channel. Warnings are displayed in the Log window and recorded in the log file. Amp: This column lists the power amplifiers by ID number and name. CH: This column lists the power amplifier channels. Wattage: This column is used to specify the wattage at which you want NetworkAmp Manager to issue a warning. Temp: This column is used to specify the temperature at which you want NetworkAmp Manager to issue a warning. Range: 1­127°C or 34­261°F. Impedance max: This column is used to specify a maximum impedance at which you want NetworkAmp Manager to issue a warning. [. . . ] RS-232C: A serial interface for connecting serial devices, offering a transmission distance of approximately 15 meters, typically using 9- or 25-pin D-sub connectors. RS-422: A balanced serial interface for connecting serial devices, offering a transmission distance of approximately 1 kilometer and higher data rates and greater immunity to interference than RS-232C. RS-485: A balanced serial interface for connecting serial devices. Similar to RS-422 but with support for multiple receivers and transmitters, offering bidirectional half-duplex communications over a single twisted pair. [. . . ]
