CONTROLS & HEADPHONE OUTPUT
1. Signal Level & Clip Indicators
The LED signal level indicators show that you are inputting a proper signal
level. With a proper input level, the green signal LED should be flickering, but
the red clip indicator should NOT ever be lit.
The clip indicators light and show that the input level has exceeded 0dBFS.
2. Left/Right Gain Controls
These controls set the input gain from 0dB to +60dB for the two inputs.
3. Direct Monitor Level Control
This continuous encoder controls the amount of direct monitor signal mixed
into the outputs. The level is adjustable from -24dB to off.
4. Direct Monitor On/Off & Mono-Stereo Switch
Press the button once to turn on Direct Monitoring. The stereo LED illumi-
nates. In this mode the left and right channels are passed through to their
respective outputs at the level set by the Direct Monitor Level control. Press
the button again to switch to Mono Direct Monitoring, which sums the left
and right direct monitor channels to mono. Mono mode is useful when the
two inputs are being used for separate instruments, or when only one input is
being used. See
“Direct Monitoring” on page 17 .
5. Headphone Jack
Connect your stereo headphones here.
6. Headphone Level Control
This knob controls the volume of the headphone output. This switch also
turns the Tracker Pre on or off.
Ground Lift Switches
There are “ground lift” switches for both analog 1/4” inputs located on the
bottom of the unit. These switches can be used to safely stop the hum if a
ground loop occurs in your setup. See
page 46 for more information.
