6 Controls and Connectors
Front Panel
Front Panel Descriptions
1.
Mic/Inst Inputs
– These Neutrik hybrid connectors will accept a low-impedance
mic level signal on a standard three-pin balanced XLR or TRS plug, or a high-
impedance instrument level signal on an unbalanced 1/4” TS plug.
2.
Mic/Line Selector
– This switch toggles the unit between the front panel Mic/Inst
inputs and the rear panel Line Inputs. Set to the OUT position, the Mic/Inst inputs
are selected and active, and the Line Inputs are defeated; Set to the IN position,
the Line Inputs are selected and active, and the Mic/Inst Inputs are defeated.
3.
Pad
– With this switch in the IN position, a 20dB pad is inserted into the input
circuit, lowering the mic or instrument input level. Use this PAD when the input
level of your analog signal is too hot – as indicated by illumination of the CLIP LED
– even with the INPUT GAIN LEVEL at or near minimum.
4.
Input Gain Level
– This potentiometer controls the input level of its associated
analog Mic/Instrument input. When the Mic/Instrument Input is in use, the variable
gain range is >40dB.
5.
Signal and Clip Indicator LEDs
– The Signal LED indicates the presence of an audio
signal at the associated Mic/Inst input, and will light when signals reach levels of
–30 dB or higher. The Clip LED will light when the signal is 1dB
below the clipping
point. If the Clip LED lights often or stays lit for any period of time, lower the Input
Gain Level on that channel.
6.
Headphone Outputs 1 & 2
– These jacks accept standard 1/4” stereo TRS headphone
plugs. Each headphone output has an associated level controller to control listening level.
Only headphone output 1 will respond to the A/B source selection, when the A/B selector
switch is configured for headphone source selection (see the “Hardware Page” section, “A/B
Source Switching” for more information, and also “Using the A/B Selector Switch”). When
using at 192kHz sampling rate outputs 1 & 2 are monitored in Headphone 1 while outputs 3
& 4 are monitored in Headphone 2.
