FRONT PANEL CONTROLS
INPUT
Socket to plug in a bass guitar.
LOW BOOST
LED to boost low end.
BASS
Control to Cut or Boost deep frequencies.
MID 1
Control to Cut or Boost low-mid frequencies
SHIFT 1
LED to set the operating frequency of MID 1
MID 2
Control to Cut or Boost high-mid frequencies
SHIFT 2
LED to set the operating frequency of MID 2
TREBLE
Control to Cut or Boost high frequencies.
HIGH BOOST
LED to boost treble.
PHONES
Headphone socket (min 200
Ω
)
GAIN
C LEDs to adjust the input level.
CONTOUR
Control boosts lows and highs, while cutting mids.
ROUGH/SMOOTH
Switch to alter the timbre of the contour.
2ND STAGE
Switch adds one output stage tube into the circuit. This feature offers the choice between a so called
hybrid amplifier (tube preamp with transistor power amp) and the sound of an all tube amplifier head.
MASTER
Control determines the mains level.
MUTE
ON/MUTE LED cuts the signal from all outputs, except from the PHONES socket, and
activates the TUNER output (rear panel). In case of signal flow at the power section (Input or Effects
Return), there might appear a popping noise when MUTE is pressed. To avoid this, mute your strings
or have effects like delays muted when pressing the MUTE button.
POWER
On/Off switch for the Mains Power.

REAR PANEL
MAINS IN AC
AC Terminal with integrated fuse compartment for connection to the mains power supply.
GROUND LIFT
Switch isolates the earth connection from the ground of signal. Should several devices be simultane-
ously connected to earth by the same conductor as well as via line connections, a so called hum loop
might appear. In this case operate GROUND LIFT to eliminate the current hum (when pressed).
FOOTSWITCH
Socket to connect a double latch footswitch with a stereo jack. The tip switches Contour on/off, the
ring switches the 2nd Stage on/off.
TUNER OUT
Socket for a tuning device. The pure bass signal is available when the amp is switched MUTE.
LINE OUT
Output for connection to an external power stage (post MASTER)
EFF. SEND &
Sockets to implement the effects loop. Connects the input of the effects to the SEND socket and its
EFF. RETURN
output to the RETURN socket.
EFFECT MIX
control determine the degree to which the effects within the parallel loop affect the signal.
DI PRE/POST
When depressed, the signal at the DI OUT socket is the pure bass signal (PRE). Otherwise it is the
signal after the tone controls and any connected effects devices have done their work (POST).
DI OUT
Balanced output for the connection to a mixing desk (PA or Studio).
SPEAKER OUT
Sockets designed to supply speaker cabinets. Lockable Coaxial Speaker Connection and 1/4" jack
socket (only TubePath 5.1) are connected parallel.
