Because the F8

+
, F12
+
, F15
+
, F215
+
, S12
+
, S15
+
and S18
+
are passive systems embodying correct
acoustic design principles, they can be used without a controller as long as their AES and peak power
ratings are not exceeded and care is taken to avoid amplifier clipping.
For maximum performance, however, we recommend that Blackline
+
Series systems are used with
Martin Audio
M3
+
,
DX1
,
DX2
or
Engineer
system controllers.
Controllers must, of course, be used with the bi-amplified H3
+
, and H3H
+
and the bi-amplified/tri-
amplified H3T
+
. Controllers must also be used when adding the S218
+
to a system as this very high
power subwoofer does not include a passive low-pass network.
8.1 M3
+
2 input, 4 output analogue system controller
The Martin Audio M3
+
2in-4out system controller provides optimised crossover, EQ and limiter functions for
bi-amplified Blackline
+
configurations (H3 or H3H), or for main-plus-subwoofer configurations (for instance,
F8
+
+ S12
+
, F10
+
+ S15
+
, F12
+
+ S18
+
or F15
+
+ S218
+
).
The M3
+
system controller may also be used as a simple equaliser and limiter for fully passive full-range
Blackline
+
applications.
Please refer to the M3
+
configuration notes later in this user guide for further information.
