circuit. This will usually (but not always) remedy most ground loop type noise from the signal path.
Sometimes it may also be necessary to lift the A.C. Cable Ground also by using a 3-2 ground adapter to achieve a quiet signal
path.
NOTE: Ground loops can occur in many places in a complex signal path. The DIRECT OUTPUT GROUND LIFT switch is not a cure-
all and therefore should not be expected to remedy every type of ground related problem.

EFFECTS_LOOP:

The Titan incorporates an internal EFFECTS LOOP to handle the interfacing of outboard processing. This
circuit is a patch point between the preamp and the power section and it is wired in series with the dry (un-affected) signal. Since
this loop is a series-type loop (as opposed to parallel) it is important that you use good quality processors "in
the middle" of your amp. While the loop is compatible with most processor Input/Output impedance demands,
there can be a lot of room for sonic compromise in some of the less expensive units. Remember that every part
in your signal path is a tone part.
NOTE: Always use good quality shielded cable of the shortest possible length when patching your effects. One
foot lengths are preferable - with lengths of more than 3 feet (each cable) starting to roll off top end and reduce midrange punch
and clarity.
The LOOP is fitted with a "Hard Bypass" switch that allows you to completely remove all associated LOOP circuitry from the signal
path when you are in the studio or when the LOOP is not to be used. While many won't be able to hear any discernible difference
with the LOOP bypassed, for you purists, it will give you peace of mind that your signal is as direct as possible.
To use the EFFECTS LOOP;
1) Connect the SEND jack to your processor's Input
2) Connect the RETURN jack to your processor's Output
3) Switch the EFFECTS LOOP BYPASS switch to the ON position.
4) Adjust the processor's Input/Output Level attenuator to achieve unity gain by toggling the LOOP switch in and out of BYPASS
while making fine adjustments at the processor until you hear no level difference. Keep in mind you might have to adjust the TI-
TAN OUTPUT control also if the processor indicating lights read unity gain (look good and are not clipping).
NOTE: The EFFECTS LOOP IS optimized for professional quality rack mount processors. Most pedal type effects work better in
the "front-end" between your instrument and the INPUT. You will experience some tonal changes because of the additional cable
and the fact that your instrument will no longer be going straight into the grid of the first tube. It's up to you to decide if the trade off
is acceptable.
Now that we have the Rear Panel sussed-out, you are ready to enjoy the musicality and shear power of the TITAN. We hope you
will find this instrument brings you many years of inspiration and musical discovery. From all of us here at MESA...Enjoy!
