OPERA TING THE HM60
The HM60 can be operated as a stand-alone monitor mixer and headphone
amplifier, or as a distribution system.
After proper connections are made, begin sending signals to the HM60.
• Set the Master Level control at appro ximately 12 O’cloc k. Carefully bring up the
1-4 and Main Mix Levels until a desired mix is achie v ed.
• Adjust the Equalizer as needed. The 64, 125, and 250 Hz sliders control the
lower or bass frequencies, the 500, 1K, and 2K sliders adjust the middle frequencies, the the 4K, 8K, and 16K sliders vary the high or treble frequencies.
• The A GC compressor k eeps transient signals lik e pops or f eedback 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 lev el or low le v el signals are effected.
• To use external effects processors, connect the FX Send jack to the Input of y our
effects unit, connect the output(s) of the processor to the Effects Return jacks
(See the connection example on P age 3). If you are using a mono signal out of the
processor, use the Right/Mono jac k.
The Effects Send controls 1 - 4 and Main adjust the amount of signal from the
indicated input out the Effects Send jack and to y our eff ects processor. Adjust the
Output Level of y our processor along with the HM60 Effects Return control to set
a desired amount of effect you w ant.
