49. MAIN INSERTS
Stereo phone jacks for the left and the right channels with breaker function. The low impedance output
is assigned to the tip (send) and the high impedance input (return) is assigned to the ring of the
connector. This jack allows the connection of external EQs, compressors, limiters, etc. into the master
L/R signal path. The insertion point is pre-master faders. As with the inserts of the monaural input
channels, different DIRECT OUT functions can be accomplished.
Please, also refer to the corresponding section in the description of the MONO INPUTS.
50. MAIN OUTPUTS
The signals at the MAIN OUTPUTS are post master fader and mainly meant to feed additional,
external power amplifiers. Through these outputs, it is also possible to run a two-way active system
set-up. In this case, the active crossovers – or active subwoofers have to be connected to the MAIN
OUTPUTS. If you want to use the internal power amplifier to supply the high frequency cabinets, the
high-frequency signal coming from the crossover has to be run back into the PSX via the POWER
AMP INPUTS.
51. EQ INPUTS / OUTPUTS
The EQ INPUTS are provided through electronically balanced phone jacks with breaker function.
When inserting a phone plug, the signal path is interrupted between the master L/R controls and the
internal power amplifier. The EQ INPUTS and POWER AMP INPUTS are the only active inputs for
the internal power amplifier.
The signals at the EQ OUTPUTS are post-master fader and post the internal 7-band equalizers.
Likewise, the MAIN OUTPUTS can be used for connecting external devices.
52. POWER AMP INPUTS
The POWER AMP INPUTS are also provided via electronically balanced phone jacks with breaker
function. When inserting a phone plug, the signal path is split between the master and the internal
power amplifier. The POWER AMP INPUTS are then the only active inputs for the internal power
amplifier.
NOTE: For detailed information on the function and operation of the “MASTER PATCHBAY” – MAIN
INSERTS, MAIN OUTPUTS, EQ IN/OUTPUTS, and POWER AMP INPUTS – please refer to the
corresponding section; later in this owner’s manual.
53. FX1/2 FOOTSW.
Phone jack for the connection of the foot switch or other compatible unit, to switch the internal FX
units on or off.
To accomplish this function, the switches FX1 and FX2 have to be engaged.
54. LAMP
This XLR-type socket provides a DC voltage of 12V /2.4 watts and is meant for the connection of a
gooseneck lamp. Please make sure that the lamp used complies with the specifications and pin
assignment. shown here. CAUTION: Overload or short circuits can result from damaging this output.
To prevent this from happening, we recommend the use of a Littlelite gooseneck lamp, available from
your Electro-Voice dealer.
For further information, please consult your dealer.
