For "stereo" operation, both A and B outputs can be inserted into an effect with mono input and
stereo outputs, thus splitting the signal at the effect before the power amp.
For mono operation, simply take your choice of jacks and turn the other to zero.
RECORDING OUT
These jacks capture a low level direct recording signal. The signal here passes through its own EQ
circuit specifically designed to simulate the sound you hear when using one of the Mesa power
amps and speaker cabinets. Difficult to obtain, we feel you'll agree with us when we say this is
"The Pre-amp" to use in the studio. Save yourself hours of patching, miking, EQing, and moving
things to try to come close to your live "sound". Simply insert one of the "Recording Out" jacks
directly into the board and set it "flat". You'll be amazed at the sound, both rhythm and lead. Some
slight EQing to capture "your" sound and your ready to roll tape.
FU-2 ONLY: This 4-Pin XLR Jack receives the cable for the FU-2 footswitch. The FU-2 only should
be connected to this jack. Always make sure the jack is plugged in securely when inserting. Push
the release pin when removing the jack from its socket.
LINE FUSE: The Quad is protected from AC surges by a 1 1/4-amp fuse. Should the fuse blow,
replace it with a Slo-Blo fuse of the same amperage.
LINE CORD: This is a standard 3 pin AC Line Cord. A ground lift (3 to 2 adapter) may be used on
the Quads AC Cord when it is being used with a power amp. This can prevent ground loops and
the hum that can arise there of. It is not necessary to lift the ground in most recording situations
when a power amp is not in use.
SUMMARY: Now that we've gone through all the controls and features you're ready to tone. Use
this manual as a reference and keep it handy for the next couple months. It helps to refresh your
memory as to the signal path and other pertinent information when searching for a particular
sound. Understanding the Quad will make it much easier and more fun to use. Start with the list of
settings we've included and from there: Be adventuresome!
It's not hard to find sounds you've only dreamed of. If you have any questions don't hesitate to
give us a call. We'd love to hear from you. Once again, we'd like to congratulate you on the
purchase of your new Quad Pre-amp. In choosing this state-of-the-art instrument you and a few
bold others are leading the way into the future: redefining what great guitar tone is while earning
respect with the ease and speed with which you attain it. You are a new breed of player and we at
MESA/Boogie are proud to be associated with you. Congratulations and most of all, Enjoy.
