FX Loop II Balance
FX mix control for FX Loop II. When the knob is set to Dry, the amp signal is routed through with no proces-
sed signal (0% wet balance) added to the mix. Twist the knob clockwise to blend in the processed signal
(parallel/passive, wet balance 1-99%, depending on knob position). When the knob arrives at the Effect
position, only the wet signal (that is, the processed signal generated by the connected effect device) is
patched to the power amp (serial, 100% wet).
NOTE:
Set this knob to Dry when the FX Loop is not in use! Settings between 9 and 3 o‘clock position reduce
the signal level. In the event of contact corrosion of the FX Return socket, volume fluctuations may occur.
Power Tube Monitor
This red LED lights up to indicate one of the internal power tube fuses has blown. You can continue playing,
but the amp‘s performance will be diminished. Normally the loss of a power tube results in an unbalanced
signal. Be sure to have a specialist look over the power amp as soon as possible; the fuse probably blew
because of a defective power tube. Once a fuse has blown, it must be replaced by a new fuse.
Line Output – 0 dB Poweramp Signal
This port taps the power amp‘s output to provide a line out signal configured at a level of about 0 dB. The
frequency response is identical to that of the power amp output signal. In other words, its frequency res-
ponse is not compensated or corrected. You can feed this signal to another linear power amp. Another op-
tion is to patch it through an outboard filter to emulate a speaker, or for example into the ENGL CABLOADER
(IR-Loader with an integrated microphone and poweramp simulation), and feed this externally processed
signal to a recording device or PA system.
