7auxes HPWTM owner’s manual

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).

52aux 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)

53insert 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.
