Recording Outputs

 
 

The 

back panel gives all the connectivity one could ask for. Use it as a fully integrated amplifier, 

as a DI, as a preamp, as a Power Amplifier. Use the features stand-alone, or combined. (Note: The 

voltage selector switches are under the cover plate, above the AC power connector)

Direct Instrument Balanced Output 

This DI Output is a balanced XLR connector, a buffered but otherwise exact replica of the instru

-

ment input except at line level. This can be routed to another amplifier or a mixing console for 

pure instrument tone unadulterated by any front panel settings. This can also be routed to a 
tuner.

Post EQ and Limiter Balanced Output 

This is a balanced XLR output jack, with a variable output adjusted by the Record Level control. 
The branch for this is AFTER the Gain/Limiter, Effects Loop 1, all the EQ controls, the Enhancer, 

and the Timbre controls, but before the front panel Volume (next to the power switch), the Effects 

Loop 2, and the Power Amp. Signals from this XLR are therefore fully controlled and tone shaped 

by the preamp; it can be routed to a mixing console, direct to the PA or direct to another Power 

Amp/Speaker System. Pin 2 is the + signal. You can also use this DI Output and a special XLR to 

Phone jack cable to daisy chain several Thunderfunk slave amps together, matching the setup 
with one set of preamp controls working all the power amp and speaker systems simultaneously. 
See your dealer for more information on possible setups.

Recording Level

 

This controls the line level strength being sent from the XLR balanced output jack. You can also 
use this DI Output and a special XLR to Phone jack cable to daisy chain several Thunderfunk slave 

amps together, matching the setup with one set of preamp controls working all the power amp 
and speaker systems simultaneously. See your dealer for more information on possible setups.
