E Snake Manual - Whirlwind

3. Line provides unity gain to the input signal. Maximum input level in this position with thefader set to zero is +18dBV.4. Pad applies a 30dB attenuator at the input to reduce the level of “hot” signals.5. 48V, when activated applies phantom power to the input connector.6. Limiter activates a protective limiter designed to minimize digital clipping that can occurwhen signals exceed digital full scale, represented by 0 in the bar graph signal meter. Thethreshold level at which limiting starts is fixed at –6 as shown in red on the meter. Duringoperation the limit light should blink on and off. If it stays lit the gain should be reduced.Analog to Digital (A/D) Converter Performance OptimizationAnalog to digital conversion is optimized by presenting the proper level of analog signal to theconverter without crossing over the threshold into digital clipping. The Gain Fader and the Gainbuttons should be manipulated together to keep the signal level on the meter in a range neardigital full scale but with a comfortable margin of headroom.Best performance is usually achieved with the Gain Fader positioned in the middle of its range(close to “0”) and with the meter reading in the –10 to –12 region. If it becomes necessary tomove the gain fader to either the high or low extreme to achieve proper level, switch the inputlevel button to a different range and readjust the fader. These adjustments will cause noperceived level changes at the corresponding MLO output channel due to Gain Tracking (seesection 1.1).Channel Text EditorDouble-clicking on the black text box within a channel when in the Channel Detail view willopen the individual channel text editor.
