Input
Peak Digital Input Meters	Peak digital input level in dB (23 dB equals full-scale digital input).
Analog Clip	Lit (red) when the input signal is clipped. This occurs when the signal level exceeds the maximum analog sine input level plus 3dB.
Phantom Power	Enables the phantom power feature which supplies power to a microphone via the audio cables attached to the device. This feature is used for condenser microphones. Note: Check the power requirements of microphones, before connecting them to the NION.
Maximum Analog Sine Input Level	The maximum expected analog RMS input level for the channel. The peak level is 3dB higher. This control scales the analog input section before the signal is passed to the analog to digital converter. Use it to adjust the sensitivity of the input stage so that the meter display moves across its full range and not just in a small area. The range is dependent on the type of card you are using.
Mute	Mutes the channel.
Invert	Inverts the polarity of the signal.
	Solo. Specifies that the channel is to remain open while all others are muted. Any other channel with Solo on will also remain open.
Digital Gain	The level of gain to be applied to digital signal inside the unit. The signal has already been converted from analog to digital by the A/D converter. The range is to -100dB to 18dB.
Output
Peak Analog Output Meters	Post-converter peak analog output level (dBu).
Mute (Relay)	Mutes the channel and switches off the relay on the output.
Maximum Analog Sine Output Level	The maximum analog output signal level as it leaves the card. This is the RMS level of the signal. When the signal level exceeds the peak level (3 dB higher than the RMS level), it is clipped automatically as indicated by the Digital Clip LED. The range is dependent on the type of card you are using.
Peak Digital Output Meters	Pre-Converter Peak Digital Output Level (dB). 23dB equals full-scale digital output.
Digital Clip	Lit (red) when the output signal is clipped. This occurs when the signal exceeds the peak level.
Infinite Clip Hold	When clicked, the hold indicators on the digital output level meters will continually show the maximum signal value. The hold indicators will only change when a higher signal level is detected.
Clip Hold Time	The time in seconds that the hold indicators on the digital output level meters will continually show the maximum signal value. The range is 100ms to 100s.
Invert	Inverts the polarity of the signal.
	Solo. Specifies that the channel is to remain open while all others are muted. Any other channel with Solo on will also remain open.
Digital Gain	The level of gain to be applied to digital signal inside the unit. The signal has already been converted from analog to digital by the A/D converter. The range is to -100dB to 18dB.
