Limiter; Vu Meter; Linking Inputs Or Outputs; Wrap-Up - Mackie SP260 Owner's Manual

Limiter

Each output has a powerful limiter that may be used
to protect loudspeakers from damage due to excessive
output levels from the mixer.
Three Limiter controls may be edited here:
• Attack
• Release
• Threshold
Use the Nav/Edit1 Wheel [7] to change the attack
time. Turning this wheel clockwise increases the
attack time, while turning it counter-clockwise
decreases the attack time. The attack time ranges
from 5 ms to 200 ms.
The attack time increment depends on where it is
currently set:
• 5 ms – 20 ms:
• 20 ms – 30 ms:
• 30 ms – 100 ms:
• 100 ms – 200 ms:
Use the Edit2 Wheel [8] to change the release
time by ±0.1 s per click. Turning this wheel
clockwise increases the release time, while
turning it counter-clockwise decreases the release
time. The release time ranges from 0.1 s to 3.0 s.
Use the Edit3 Wheel [9] to change the threshold
by ±0.2 dBu per click. Turning this wheel clockwise
increases the threshold, while turning it counter-
clockwise decreases the threshold. The threshold
ranges from –10.0 dBu to +20.0 dBu. A setting of
+20.0 dBu is off.
Press the ESC button [11] to exit limiter editing
mode.

VU Meter

You may choose between viewing the signal level or
the limiter's gain reduction for each output. These will
be displayed on the 7-segment LED meters [16].
Turn the Edit2 [8] or Edit3 [9] Wheel to scroll
between VU-Meter = Level [default] and VU-Meter =
Limiter Act. If the latter is selected, the Clip LED on
the selected output(s) will illuminate to indicate 0 dB
of gain reduction. When the signal level exceeds the
limiter threshold, the top Limit LED will illuminate to
indicate gain reduction is occurring. Additional LEDs
will illuminate for every 3 dB of gain reduction.
Press the ESC button [11] to accept the update and
exit VU Meter edit mode.

Linking Inputs or Outputs

It is possible to link multiple inputs or outputs
and edit specific parameters simultaneously.
This is handy if you want to set the gain on both
inputs to +1.0 dB, for example. Or you could introduce a
3 dB cut at 250 Hz on EQ band 3 on output channels 1-4.
This saves valuable time rather than having to make the
same change on each input or output. The changes are
absolute, not relative, so if you want different values for
the same parameter across other inputs or outputs, you
need to make these changes on each input or output. To
link, simply press and hold any additional input or output
Mute / Edit buttons. Any changed parameters will affect
all linked inputs or outputs.

Wrap-up

The SP260 contains a minimal amount of knobs,
buttons and other bells and whistles, but it is packed
with features awaiting your every command. With
little effort, you will be a master of the SP260 2x6
Speaker Processor in no time. Please accept our
congratulatory virtual 'Certificate of Achievement',
you deserve it...it looks great when framed!
