monitor output 1/4" TRS jack (rear panel)
The monitor output signal is available on these output jacks. The jacks are
impedance-balanced and ground-compensated.
Tip is +Drive, Ring is -Drive Return, Sleeve is Chassis Ground
Send (Drive) impedance is 50Ω
Ring impedance is 50Ω to Audio Ground
Nominal Operating Level= +4dBu
Max Output Level= +21dBu (into 2kΩ or higher)
solo operation
The HPW is equipped with a stereo solo bus that allows the operator to monitor
the various signals within the Console. All Input channels have a PFL (Pre-Fader
Listen) switch. Outputs are equipped with an AFL (After-Fader Listen) switch. The
PFL circuit on the Inputs allows the operator to properly set the channel’s internal
signal level using the channel’s Gain pot and Pad switch. Since the signal being moni-
tored is PFL the mute status, the channel fader level and any bus assignments, are
ignored. This allows a channel to be monitored and adjusted without being sent into
any of the main mixes. The operator has a chance to properly set the levels and EQ
of a channel before anyone else might hear it.
For Outputs, the AFL signal point allows the operator to hear exactly what is being
fed to the outside world. The output level, as well as any inserted processing gear,
can be monitored by the Solo system. For times that a Pre-Fader point needs to be
checked, the Monitor Sources can be used to listen to a bus before its main fader.
solo metering
Whenever a Solo button is pressed (PFL or AFL), the SOLO LED indicator will
illuminate and the Monitor Source LED meters will switch-over to display the Solo
bus level. These meters are calibrated to properly display the different internal levels
within the console. The 0VU point is the nominal operating level of whatever signal
is being Soloed. Use the Solo system and metering to set the gain of an Input chan-
nel, monitor the output level of a bus, or check on the vocal blend of an Aux moni-
tor mix.
NOTE: Since the Solo
system uses a sum-
ming bus, if more than one
source is selected (PFL switch
is depressed), the signal being
displayed and heard is a mixture
of those selected signals. When
setting the gain of an Input chan-
nel, make sure that only 1 Input is
selected to avoid errors.
