1 Before making any connections between the Minidrive and the amplifiers, make sure that
the amplifiers are switched off and that their level controls are turned completely down.
2 Connect the audio source to the inputs of the FDS-334T/336T, left to A and right to B. For
a mono system, use Input A.
3 Connect the outputs of the Minidrive to the amplifier input channels (maintaining the left
and right identification). Typically the higher the number of the Output, the higher the
frequency content. i.e. In a 2 channel 3 way configuration, Outputs 1 & 2 are Low, 3 & 4
are Mid and 5 & 6 are High. The Output assignments vary depending upon the type of
system configuration and Program loaded into the FDS-334T/336T.
4 Turn on the power to the console, Minidrive(s) and finally the amplifiers. (It is best to turn
the amplifiers on last and off first to prevent any thumps or pops from damaging the
transducers.)
5 From new the Minidrive does not contain any preset Programs but, if the unit has been
used before it may contain user preprogrammed setups. To select an appropriate Program
press RECALL. Use the up/down buttons located on the left side of the LCD screen to
choose the correct Program. Press RECALL again to enable the Program.
6 Apply a signal source to the Minidrive. This could be pink noise, a tone or music.
7 Check the gain, limiter and crossover settings are correct for your application. If you can’t
see or get access to these settings within a particular Program this means that they have
been locked out uisng either OEM or Owner lock. A password will be needed to regain
access to change these parameters.
8 Unmute the Outputs on the FDS-334T/336T, one at a time - muted is the default setting.
A lit red LED on an Output mute button signifies that the output is muted.
9 Advance each amplifier channel slowly and confirm that the signal reaching the speakers
is correct. It is best to begin with channels driving the low frequency drivers first. In this
way, if the high and low are reversed, high frequency signals will be going to a bass unit.
It’s better to find this problem than the low frequencies going to the high frequency driver!
10 After it is confirmed that all transducers are receiving the proper signals, initial calibration
can begin.
