Using the Holophone H4 SuperMINI
The Holophone SuperMINI is remarkably simple to use, because it
accurately reproduces in three dimensions what you would hear at
a particular location in space. In most cases, if you have
experience recording sound with traditional microphones, you can
rely on your ear and your intuition as to the appropriate placement
for a particular event or venue.
The Virtual Surround Sound Headphone capability provides quite
an accurate impression of the sound that is being captured and
enables monitoring in three dimensions.
Setting Levels
First listen to source material through the headphones with the
jack in the H4 SuperMINI Control Unit. Then check the levels on
the two coloured LEDs on the H4. The greens should be lighting
with very occasional reds. If the red LED is lighting consistently,
your gain is too high, and must be reduced using the gain knob.
Next look at the recording device‘s audio display to confirm that
input from the H4 SuperMINI is at the optimal level for the
specific device. Move the headphone monitor to the recording
device to confirm the device’s recording level.
Monitoring from either source is optional once the optimal levels
have been achieved.
The Mic Gain Dial should be used only for minor adjustments.
This is because it is possible to overload the recording device
without being aware of it.
Audio Zoom
Audio zoom increases the forward bias of the surround sound. It
does not “zoom” incrementally, but simply adjusts the levels of the
channels to a second set of values:
Center: plus 6 db
R & L: plus 3 db
SR & SL: minus 3 db
