The Max Amp
1. Headphone Ouputs
The headphone out is where you plug in your
headphones. The Max Amp is equipped with two 1/4” jacks.
2. Rear Output Switch
If you want to use your Max amp as a pre-ampli-
fi er, a set of RCA connectors on the rear faceplate act as analog out-
puts for hooking up a power amplifi er or powered speakers.
3. Brightness Switch
The Brightness Switch is used to compensate
for the warming action of the processor. In the center position there is
no fi lter in the circuit; generally this is preferred. But if the processor
is causing too much bass or blurring of the central image, a mild high
frequence boost fi lter can be turned on. The “fi lter 1” setting accen-
tuates the highs at about 3 kHz; with the “fi lter 2” setting the fi lter
starts an octave earlier and catches some of the upper mids. Basically,
set it to whatever sounds best to you. You can read more about the
Brightness switch on page 7.
4. Crossfeed Switch
This switch engages the crossfeed circuit. Audio
imaging on headphones is often not very good; typically the image is
a blob on the left, a blob on the right, and a blob in the middle. The
HeadRoom crossfeed provides the natural acoustic cross-feed normal-
ly heard at the left and right ear as heard from the left and right speak-
er. Adding back the normally occurring cross-feed signal gives your
brain enough information to build the stable and natural audio image
needed to have a quality listening experience. Read more about the
crossfeed switch on page 8.
5. Gain Switch
The 3-position Gain Switch accomodates various head-
phones’ power needs. For instance, the Low Gain setting would be
used for in-ear monitors, allowing a larger range on the volume con-
trol pot. Experiementing with your headphones and the gain switch
may help you to determine which setting you prefer. If have any ques-
tions regarding your headphones, feel free to call and ask us.
6. Volume Control
As you turn the volume control knob clockwise, the
volume increases.
You never know where the volume control should
be set as different headphones often have widely different impedanc-
es and effi ciencies, so use your ears to choose your listening level, not
the level on the dial. (We recommend you choose a moderate level so
as not to blow out your ears.) You also need to turn the amp OFF or ALL
THE WAY DOWN before plugging in or unplugging your headphones to
avoid short-circuiting the amp.
