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.
