Headphone Output. When in the 12 O’clock position, the knob has no effect.
AGC COMP: This switch engages the Automatic Gain Control compressor.
MASTER OUT: Controls the level of all signals sent to the Headphone Output.

OPERATION
OPERATING THE HM58
After proper connections are made, begin sending signals to the HM60 or HM57,
whichever is connected to the signal sources and your HM58.
• Set the HM58 Master Level control at approximately 12 O’clock. Carefully bring
up the AUX 1 - 4 levels until a desired mix is achieved.
• Adjust the Equalizer as needed.
• The AGC 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 may not
notice any effect. Only very high level or low level signals are effected.
• If using external effects processors, make sure they are properly connected to
the HM60, and the levels are set properly. Refer to the HM60 owners manual, as
well as the operating manual of the effects processor.
If you have an effects processor connected to the HM60 control unit, the HM58
Effects Return adjusts the level of the effected signals to your 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.
CONNECTION
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 expansion
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.
