OPERATION
CONNECTING THE HM58
Shown below is a connection diagram for the HM58. The male Expansion jack,
shown below on the left side, is the INPUT, the female Expansion jack, shown
here to the right, is the OUTPUT or through jack. So connect the DB25 e xpansion
cable from the female OUTPUT Expansion jack of either the HM60 or HM57 to
the male INPUT Expansion jack on the HM58. The female OUTPUT Expansion
jack on the HM58 may then be connected to another HM58 or HM59.

OPERA TING THE HM58
After proper connections are made, begin sending signals to the HM60 or HM57,
whichever is connected to the signal sources and y our HM58.
• Set the HM58 Master Level control at approximately 12 O’clock. Carefully bring
up the AUX 1 - 4 le vels until a desired mix is achieved.
• Adjust the Equalizer as needed.
• The A GC compressor keeps transient signals like pops or feedback under
control, so they won’t damage your hearing. It also slightly brings up low-level
signals.
NOTE: Much of the signal content may not be compressed, you ma y not
notice any effect. Only very high level or lo w le vel signals are effected.
• If using external effects processors, make sure the y are properly connected to
the HM60, and the levels are set properly. Refer to the HM60 owners man ual, as
well as the operating manual of the effects processor.
If you hav e an eff ects processor connected to the HM60 control unit, the HM58
Effects Return adjusts the level of the eff ected signals to y our headphone mix.
Note that the Effects Sends 1 - 4 and MAIN on the HM60 determine the mix of
signals sent to the effects processor . The HM58 FX Return control will only adjust
the level of that mix. In other words, the signals present at the Right and Left
Effects Return jacks on the HM60 will be the signals adjusted by the FX Return
control on the HM58.
