Input 1-2 Overview
The Input 1-2 Overview has 3 different presentations, based on the Preamp setting: SD-MP, AP-66
and AP-57.
1. Input Gain - tap to set the gain of the preamp
with the Control knob, when Analog Level is
set to Mic or Instrument. Gain Control is
hidden when Analog Level is set to +4dBu or
-10 dBV line input.
2. Digital meter - displays the digital level after
A/D conversion
3. Lo-Z Impedance - (AP-66 only) set the
impedance of the mic preamp to low (300
ohms) when using low impedance mics, such
as certain ribbon mics.
4. Output level - (AP-66, AP-57 only) tap to set
the output level of the mic preamp stage.
5. GL - Gain link - (AP-66, AP-57 only) link the
Input gain to the Output level so increasing
the Input gain reduces the Output level to
maintain a consistent signal level. This is
useful when driving the mic preamp emulation
into distortion.
6. -20 db Pad - (AP-57 only) decreases the
sensitivity of the analog input by 20 dB.
Engage the -20 dB pad when gain is set to 0
but the input is still overloading.
