aux connectors-rear panel
The HPW Aux output connections are located on the Master rear output panel. All
of the auxiliary outputs are fully balanced with auxes 1-8 featuring XLR connectors
and auxes 9 and 10 having 1/4” TRS connectors. All 10 auxes also have TRS inserts.
The TRS Insert jack is wired as Tip=Send, Ring=Return, Sleeve= Audio Ground. This
is the “industry-standard” wiring scheme for most single-jack inserts. The Insert send-
point is located directly after the aux mix amp. The Insert return feeds the top of
the level pot, or the top of the 100mm fader if Fader-Reverse is active (see Block
Diagram).
aux output 1/4" TRS and male XLR jacks
The aux output signal is available at this output jack. The output is fully balanced.
Tip positive, Ring negative, Sleeve is Chassis Ground
Outputs 1-8 XLR Balanced, 9-10 TRS Balanced
Nominal Operating Level= +4dBu
Max Output Level= +26dBu (into 2kΩ or higher)
insert jack 1/4" TRS jack
This switching 1/4” TRS jack allows an external signal processor to be inserted into
the signal path of the aux bus. The tip carries the SEND signal from the aux, and the
ring carries the RETURN signal back to the aux. The Insert-Send point is located
directly after the aux mix amp, the Return comes back at the top of the aux level
control. Tip is Send; Ring is Return; Sleeve is Audio Ground.
Send (output) impedance is 50Ω
Return (input) impedance is 5KΩ
Nominal Operating Level= -2dBu
NOTE: To avoid any degradation of the HPW’s aux signal, any processing gear
patched into the insert jack should have a low impedance output (<100Ω) and must
be capable of cleanly driving a 2KΩ load to +21dBu.
NOTE: The Fader-
Reverse switch
does not change the
function of any of the rear-
panel jacks. The Aux Output
and Insert jacks are always
located here. Similarly, the
Group Output and Insert
jacks always retain their
same function.
