External Switch Jacks; Record Outputs - Mesa/Boogie Formula Pre Owner's Manual

worked much to our favor. We have long felt this to be true and in fact included this tip in some of our other products' owners manuals.
To verify our findings we recently took a census of TriAxis (Programmable Pre-amp) users among our phone-in customers and touring
artists and found that most used their processing between pre-amp and power amp, saving their effects loops for more specific
switchable applications. When asked why, in almost every case they said they liked the sound better between the pre-amp and the
power amp. So try both ways for your specific application and choose the one that fits your ears and patching requirements best.
There is no right or wrong way to interface processing to your Formula, so experiment at will.
NOTE: If you intend to record with the Formula's Direct RECORD OUTPUTS and you wish to use the same processing you use in
your live rig and print it to a track (s) - you will need to feed the processors from the RECORD OUTPUTS, not the MAIN OUTPUTS.
From there you will need to connect either one (or both if stereo) of the processor's OUTPUTS to the console's LINE INPUTS. The
signal should be of a adequate level and the blend should be close to what you are used to in your live rig.

with the original signal so that any processing you have in the LOOP will appear at the RECORD OUTPUTS. The jacks are wired such
that if you do not have a console with balanced inputs or you simply do not wish to use the balanced signal, you may connect a regular
(shielded) mono 1/4" plug into the RECORD jacks and produce an unbalanced signal. While in most pro studios virtually all signa ls
are balanced, this has no bearing on the quality of performance you can obtain on an unbalanced project or home studio environment.
The main difference might be that of a slight roll off in the top end harmonics due to cable capacitance. This is best avoided by
maintaining the shortest lengths of cable from the Formula to the console. (This rule applies to all cabling in an unbalanced s tudio
format.)
NOTE: These Outputs work in conjunction with the Front Panel RECORD VOICE mini toggle switch which, as discussed earlier,
zeroes in on the sound style selected and tunes the voicing accordingly.
NOTE: REFER TO FRONT PANEL SECTION - RECORD.
The levels present at the RECORD OUTPUTS are determined by the settings of both the individual Channel
SIGNAL LEVELS:
MASTERS' and the final OUTPUT control. As discussed earlier under OUTPUT in the Front Panel section, settings between 9:30 and
12:30 seem to produce the best results for most all situations. For direct applications in many consoles we have found the 11:00
region to be a good starting point. This region, with similar settings on the individual channel MASTERS, seems to produce a very well
behaved SIGNAL LEVEL for most applications. Set the console accordingly and you should have lots of room to adjust for different
sounds in all three channels.

recording amplified guitar.
Two transformer balanced 1/4" TIP-RING - SLEEVE RECORD OUTPUTS jacks are provided, creating a
stereo source for your recording needs that can be used in either balanced or unbalanced consoles.
These two outputs are fed a signal right after the junction where the EFFECTS LOOP'S RETURN'S join
midi programs. The jacks respond to any tip-to-ground latching type switch logic.
The Front Panel CHANNEL SELECT toggle switch must be in the center (LEAD)
position for the EXTERNAL SWITCH jacks to respond to the external switching
source.
