Control Unit Functions
The H4 SuperMINI Head is only part of the story. Typically, in
videography, the sound is captured in stereo, to be stored either in
the camera or in a separate stereo recording unit. The H4
SuperMINI system converts the six surround channels to Dolby
ProLogic II, encoding the 5.1 channels within two stereo channels.
The result can be played (and edited) in stereo or decoded back
into the original 5.1 channels.
The encoding is carried out within the Control Unit. The Head is
mounted on the Control Unit and the two together can be mounted
on the video camera using either a hot-shoe or cold-shoe mount.
(SuperMINI can’t be powered from hotshoe mount)
Despite its small size, the H4 SuperMINI is a highly versatile
piece of equipment.
Here is what it can do:
• Encodes the input from the six microphone inputs in Dolby
ProLogic II format, exporting the result as two channels of
stereo audio.
• Provides simultaneous six-channel output, converting the
six channels of audio from mic level to line level, making
them available via three stereo outputs (six channels).
• Provides the ability to replace the center channel
microphone with an external microphone (e.g., lavalier or
shotgun), with an independent gain control. Supplies
phantom power for the external microphone, if required.
On playback, audio from (external) center mic is played
out of center (dialogue) speaker.
• Provides virtual surround headphone output for
monitoring, with a separate gain control.
• -12 db PAD switch
• Zoom button, to change the center bias of the inputs to
match video close-ups.
• Two colored LED monitor for six input channels.
• Runs on 4 x AA batteries with over 6 hours of battery life.
Alternatively, provides input for 5 V DC input converted
from AC power.
