Getting Started
READ THIS PAGE!!
Even if you’re one of those people
who never reads manuals, all we ask
is that you read this page now before
you begin using the HM-54. You’ll be
glad you did!
Zero the Controls
1. Turn down all the INPUT LEVEL controls.
2. Set all push button switches to their “out” positions.
3. Turn the POWER switch off.
Connections
1. Connect the left and right outputs from your mixer
to the LEFT and RIGHT MAIN LINE INPUTS on the
rear of the HM-54.
2. Connect any specific outputs (mix buses, subgroups,
or aux sends can be used, or a direct output from
a specific device will also work) to the desired
headphone amp LEFT and RIGHT DIRECT INPUT.
3. Plug in four sets of headphones to the front of the
unit. If you are hard-wiring the installation, you
may want to use the rear output jacks.
4. Connect the detachable linecord to the AC socket
on the back, connect it to an AC outlet properly
configured for your particular model, and turn on
the HM-54’s power switch.
Set the Levels
1. On your mixing console, get a reasonable stereo mix
going.
2. Using the subgroup or aux send that you have
connected to headphone amp 1’s direct inputs,
create a unique headphone mix. Leave the master
subgroup or aux send level control all the way
down.
3. Turn the MAIN INPUT LEVEL halfway up to the
center detent position. This is just a starting point.
We can adjust it later, if necessary.
4. With music going through the main mix, don the
headphones for headphone amp 1 and S-L-O-W-L-Y
turn up the LEVEL control on the front panel for
the corresponding headphone amp. Adjust for a
comfortable listening level.
Note: If the volume gets really loud, really fast, turn
down the MAIN INPUT LEVEL control until you
can turn up the headphone amp LEVEL control at
least halfway. Conversely, if you have to turn the
headphone amp LEVEL control all the way up, turn
up the MAIN INPUT LEVEL control a little more.
5. Push in the SOURCE select switch on headphone
amp 1 and S-L-O-W-L-Y turn up the master
subgroup or aux send level control feeding the
DIRECT INPUT to headphone amp 1. Adjust for
a comfortable listening level, equivalent to the
volume level of the main mix.
6. Repeat for headphone amps 2-4.
7. Now the individual performers can tweak their own
headphone mixes to suit their individual tastes.
Other Nuggets of Wisdom
• Always turn the HM-54 off before making or
changing connections.
• When you shut down your equipment, turn off the
amplifiers first. When powering up, turn on the
amplifiers last.
• Never listen to loud music for prolonged periods.
Please see the Safety Instructions on page 2 for
information on hearing protection.
• Save the shipping box! You may need it someday,
and you don’t want to have to pay for another one.
That’s it for the “Getting Started” section. Next comes
the “Hookup” section that shows you some typical ways
that you might use the HM-54 in real applications. After
that, you can take the grand tour of the HM-54, with
descriptions of every knob, button, input, and output.
We encourage you to take the time to read all of the
feature descriptions, but at least you know it’s there if
you have any questions.
