DI (Direct Injection) – Use DI mode when connecting an unbalanced, high impedance source (Electric
Guitar, Bass Guitar, etc). The signal will be reduced by -20dB (-35dB with pad engaged) and converted
to a balanced signal via the transformer connected to the XLR output. Use the gain on your mixer or
preamp to bring the signal up to line level.
LI (Line Isolator) - Use LI mode when connecting your unbalanced, low impedance source (Amp + Cab
Sim like the ACS1, keys, etc.). The signal will remain full volume and be converted to a balanced signal
via the transformer connected to the XLR output. Less preamp gain will be required in LI mode.
Note - When deciding between DI or LI, check with the manufacturer of your gear to find
the output impedance of the device you are wanting to interface. For a general guide:
High Impedance = anything above 1k = Use DI
Low Impedance = less than 1k = Use LI
If you lose high-frequency information when using LI mode, then you should probably be
in DI mode.
PAD – Enables a -15dB input pad (Only in D.I. mode) for reducing hot signals in order to minimize
distortion.
GND LIFT – Isolates the GND pin on XLR to help reduce hum if present. Leave out for normal operation.
SUM – Sum switch turns the Thru channel into a second input when engaged, allowing stereo input
signals to be summed to the XLR output.
THRU - The Thru jack is a pass through that can be plugged into a guitar amp or other source.
You are the artist. Your sound is the paint, and
this is your canvas. After years of creating tone-
painting devices, Walrus Audio is releasing The
