Tascam DS-M7.1
Digital Surround Monitor Controller
|
|
The DS-M7.1 surround monitor controller
was developed to provide professional sound engineers with an easy way
of playing back
surround mixes in various formats. However very few medium-range
digital mixing consoles support "downmixing", the conversion
of surround formats with several channels into formats with fewer channels.
But this
is no problem for the DS-M7.1, which can convert, for instance,
a 7.1 mix into a 5.1 mix or a 6.1 mix into a stereo signal without having
to
create a new mix. At the same time this flexible system allows
you to connect a surround stem recorder, a digital mixing console (e.g.
Tascam
DM-24) and a master recorder.
The DS-M7.1 is easy to operate: the most
important and most commonly used functions have illuminated pushbuttons – mute buttons, for example, can be used to mute any given channel – ,
whilst other functions can be accessed via the main menu.
The entire unit is made up of a 3U 19-inch chassis. The operating panel
can be removed
and used as a remote control.
Various different formats are available
for downmixing, including 7.1, 6.1, 5.1, 4.1, LCRS, stereo and mono.
Every channel has
a delay option for compensating signal delay in larger environments,
and can be set to given levels – a process which is simplified considerably
thanks to the integrated pink noise generator and LED display.
The DS-M7.1 also has an integrated bass management function which generates
the sub-bass
signal and which can be used to simulate systems with and
without subwoofer. Output signals are given in digital (AES/EBU) and
analog formats, and
for further digital formats there are three expansion slots
which can be fitted with Tascam interface cards (IF-AE/DM, IF-TD/DM,
IF-AD/DM).
The DS-M7.1's versatility and flexibility make it an ideal solution for surround monitoring control applications ranging from post-production for film and video to surround production for music, theatrical production and television broadcast.
