EXTERNAL SWITCHING JACKS: These three 1/4” jacks make it possible to trigger the two channels of the
Recto Pre
with an external
switching device so that it can be used in a midi controlled rack system. In this scheme the channels can be called up under 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 (FOOTSWITCH) position
for the EXTERNAL SWITCH jacks to respond to the external switching source.
RECORD OUTPUTS: This is the stereo pair of outputs to a recording console or a live mixing board for Direct applications. The two jacks
provide a BALANCED output and this is achieved by using stereo jacks that are wired as standard TRS (Tip, Ring, Sleeve). The signal
level is controlled in tandem (for both jacks) via the dual element
RECORDING OUTPUT Control on the lower right of the Front Panel.
The signal level range and output impedance is matched to meet
the needs of this environment and should provide seamless inter-
facing for all your direct needs. These outputs represent years of R
& D and substantial circuitry devoted to recreating the sound and
feel of a live power amp driving guitar speakers, without any of these
crucial components involved. We think you will be extremely pleased
with the results of these tailored outputs and will find as we, and the players we know have, a new and inspirational way to get keeper
tracks fast and accurately…putting the spontaneity back into the mix.
As mentioned earlier in the Front Panel section of this manual, the
Recto Pre
was from its inception, a recording pre-amp. Special
emphasis was placed on achieving a direct sound and feel that would enable guitarists to record keeper tracks without the time and hassle
normally associated with recording amplified guitar.
These two transformer balanced 1/4” TIP - RING - SLEEVE RECORD OUTPUTS jacks can be used in either balanced or unbalanced
consoles. Both Outputs are fed a signal right after the junction where the EFFECTS LOOP’S RETURN’S join 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 signals 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 capacitance from longer cable lengths. This is best avoided by maintaining the shortest
lengths of cable from the
Recto Pre
to the console. (This rule applies to all cabling in an unbalanced studio format.)
NOTE: These Outputs work in conjunction with the Front Panel Voicing mini toggle switch which, as discussed earlier, zeroes in on the
sound style selected and tunes the voicing accordingly.
SETTING SIGNAL LEVELS: The levels present at the RECORD OUTPUTS are determined by the settings of both the individual Channel
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 both
channels.
NOTE: Avoid OUTPUT level settings above 1:00 when using the RECORD OUTPUTS as it is possible to overload the RECORD
circuitry - as well as the input stage of many consoles - with certain settings of the channels and certain pickups.
