A Tour of Your Supreme HeadRoom Amp
1.
The Power Switch/ LED.
1 is On, 0 is off. When the amp is on, the
glowing red LED tells you so. When using the amp portably, make sure to turn your
unit OFF when you are not using it to avoid battery drain!
2.
The Headphone Jack.
Upgraded from past models, this is a 1/4” headphone
jack. Adaptors for 1/8” jacks are available, as well as splitters to run more than one
pair of headphones.
3.
The Volume Control.
We recommend turning the amp OFF or ALL THE
WAY DOWN before plugging in or unplugging your headphones to avoid short-
circuiting the amp.
As you turn the volume control knob clockwise, the volume
increases.
4.
The Filter Switch.
The filter switch is used to compensate for the warming
action of the processor. In the center position there is no filter 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 filter can be turned on. The “bright”
setting accentuates the highs at about 3 kHz; with the “brighter” setting the filter
starts an octave earlier and catches some of the upper mids. Basically, set it to what
ever sounds best to you.
5.
The Processor Switch.
This switch engages and disengages the headphone
audio image processing circuit. Headphone audio imaging is 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 audio image processor provides the natural acoustic cross-feed normally
heard from the left speaker to the right ear, and from the right speaker to the left
ear. Adding the cross-feed signal gives your brain enough information to build up
the stable and natural audio image needed to have a quality listening experience.
6.
Gain Switch.
The 3-position Gain Switch accomodates various headphones’
power needs. For instance, the Low Gain setting would be used for Grado
headphones, allowing a larger range on the volume control pot. Experiementing
with your headphones and the gain switch may help you to determine which setting
you prefer. If have any questions regarding your headphones, feel free to call and
ask us.
