Loading... Please wait...Minidrive provides all four core functions of the Omnidrive range: crossovers (Linkwitz-Riley, Bessel or Butterworth), mid-band limiters, equalisation freely assignable to inputs and outputs, and both input and output delay. However, by leaving out the more advanced features in the Omnidrive, BSS has achieved dramatically lower prices, ensuring that Minidrive is suitable for a range of applications for which an Omnidrive would simply not have been affordable.
The Minidrive is available in two models:
The FDS-336T is able to drive a stereo 3-way system, and is expected to find favour in the front of house rack, while the FDS-334T is expected to be at home in the monitor rack. Up to 38 bands of filtering are available in each unit.
As an added bonus, the Minidrive can be controlled by SIASoft's Smaart Live analysis program, allowing the installer or engineer to create systems with integrated measurement and processing.
Individual Minidrive outputs can also be run full range. With the low price of the units, this means that they are highly suited to use as zone controllers for convention centres, ballrooms, under-balcony feeds or downfills with EQ and delay, or for replacing several traditional analogue units in an installed sound system in just one rack space.
BSS has provided Minidrive with a similar user interface to its big brother the FDS-366T "Omnidrive Compact Plus". The four-arrow "navipad" allows access to menus and facilties, while push-to-select switches on the output level controls ensure fast access to channels for editing. Data is shown on a bright blue LCD display, with data entry via a parameter wheel. Input and output level meters are an immediate comfort for the engineer, and individual output band mute keys are provided. Together, these make the Minidrive more convenient and faster to set up and adjust than any DSP unit in its class.
For program archiving and storage, use MINISTORE, a PC application that allows you to dump programs from your Minidrive to a PC, arrange them and download any or all programs to any similar Minidrive unit.

Testmonials:
"The cleanest and clearest filters I've heard to date"
Andy Dockerty, Adlib Audio, UK
"The new filters allow me to put more power to the devices without fear of overload or over-excursion. Once adjusted, sounds better than standard filters. The system seemed louder and clearer. We were setting off alarms in the car park!"
Ferrit, Promix/Electrotec, Las Vegas, Nevada, USA\
"The biggest step forward in digital crossover technology since Linkwitz-Riley"
Jerry Wing, Britannia Row Productions, UK
