REAR PANEL CONTROLS
MAINS INLET SOCKET: Make sure the voltage indicated on the rear panel is correct for your country!
MAINS FUSE: This drawer contains the main safety fuse for the unit. The fuse protects the amplifier from damage in the
event of fault by disconnecting the mains power supply.
HT FUSE: This fuse disconnects the high voltage DC power to the tubes within the amplifier in the event of a fault.
Replacing fuses - USE ONLY THE CORRECT SIZE AND RATING SPECIFIED ON THE PANEL. - Using a fuse that is
too large in current rating may cause serious, irreparable damage to the amplifier and presents a serious fire
hazard. The fuse ratings are detailed in the Specifications section of this manual, as well as printed on the rear of
the amplifier. Fuses are designed to protect, do not take chances.
BIAS SWITCH: This allows the use of either 6L6 or EL34 output tubes in your amplifier. Ensure that the switch is in the
correct position for your output tubes, otherwise you may risk damaging your amplifier.The TI100 is factory fitted with 4x
matched 6L6 tubes. We recommend the use of matched sets of output tubes for optimum performance.
POWER AMP IN: This socket provides the user with an input to the power amplifier stage. When a Jack is connected to the
Line In socket the preamp signal does not pass to the power amp.
PRE AMP OUT: This socket gives the user an output for driving other amplifiers, mixing desks etc. . Can also be useful in
multi-amp setups where a single preamp can drive several power stages. The line out is an (unbalanced) line level output.
FX RETURN GAIN: This control serves two purposes:
1) Side Chain Mode: It controls the mix level of the global FX
2) Insert Mode: It behaves as an overall level control for the global FX Return.
