1. Power Switch - Turns the Powercab 112 unit on or o.
2. AC In - Connect the included IEC power cable here.
3. Volume Knob - Controls the output of the power amp to the speaker
system. 12 o'clock is -6dB from maximum.
4. Signal LED - Bright green indicates the presence of an input signal,
orange indicates that it is approaching the limit of the unit's output
capabilities, and red indicates digital clipping. If you encounter
clipping, try turning down the level of the source device (e.g. - your
amp modeling device).
5. Mode Button and LED Ring - Push the button to cycle through
dierent speaker modes. The button's LED color indicates the
speaker mode in use. See "Powercab Speaker Emulation Modes."
6. Low Cut Switch - Toggles the 80Hz Low Cut Filter on/o, useful for
removing unwanted low end vibration (does not apply to the XLR Out).
7. Ground Lift Switch - Controls whether the ground circuit is lifted
for the XLR Output Jack. Can be useful for identifying ground loops,
which can cause an unwanted hum.
8. XLR Output Jack - Connect to an analog mixer's input. The output
is Line Level with a maximum of +13dBu.
TIP: This XLR Output is not aected by 48V phantom power.
9. Combo Input Jack - Connect the Line Level output of your amp
modeler to this balanced 1/4" TRS/XLR input (e.g. - Line 6 Helix or
POD device, etc.). A Helix device should be set to Line Level. A
POD HD device should be set to +4dB. Analog preamp pedals may
require a D.I. Box to achieve the appropriate Line Level for this input
(maximum +13dBu).
Powercab Speaker Emulation Modes
These modes are meant to sound like taking a boutique speaker and
wiring it up in your own custom 1x12 cabinet. To achieve the most
realistic tone, we've designed the Powercab active guitar speaker
system to sound like a high-powered 1x12 cabinet rather than emulate
the sound of a 4x12 cabinet. To use these Speaker Modes, disable
cabinet emulation blocks in your digital modeler and let the Powercab
active guitar speaker system take over to provide the accurate speaker
sound and feel. An added benet is that these modes provide a variety of
speaker tones that can be captured through a traditional microphone at
any placement, thanks to the coaxial speaker system design.
FLAT – (Speaker emulation is disabled) This "full-range, at-response"
mode is ideal for simply plugging in as if you were connecting
directly to a PA, active monitor, or recording interface. It provides a
at frequency response, ideal for guitar signals that already include
cabinet emulation or for playing back music and backing tracks.
