Vu Meter; Linking Inputs Or Outputs; Control Application - Martin Audio BlacklineX SERIES User Manual

BlacklineX
Each output has a powerful limiter that may be used to protect loudspeakers from damage due to excessive output levels from
the mixer. Limiter parameters are published for all Martin Audio systems on our website and whilst we accept that personal
preference may mean that other parameters may be changed from our published figures‐ EQ changed for personal preference
for example‐ we would strongly recommend that the recommended limiter parameters are always used to maintain reliable
operation for many years.
Three Limiter controls may be edited:

Attack

Release

Threshold
Use the Nav/Edit1 Control [7] to change the attack time. Turning this Control clockwise increases the attack time, while turning
it anti‐clockwise decreases the attack time. The attack time ranges from 5ms to 200ms.
The attack time increment depends on where it is currently set:

5 ms – 20 ms: ±1 ms per click

20 ms – 30 ms: ±5 ms per click

30 ms – 100 ms: ±10 ms per click

100 ms – 200 ms: ±20 ms per click
Use the Edit2 Control [8] to change the release time by ±0.1 s per click. Turning this control clockwise increases the release time,
while turning it anti‐clockwise decreases the release time. The release time ranges from 0.1 s to 3.0 s.
Use the Edit3 Control [9] to change the threshold by ±0.2 dBu per click. Turning this Control clockwise increases the threshold,
while turning it anticlockwise 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] Control 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 useful 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 and of course is more accurate.
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.
Control Application
The DX0.5 can be controlled from a PC running the DX0.5 Application which is available as a free download from the Martin
Audio website. The application uses the USB connection to connect and enables a much easier way of editing the system
configuration compared to using the front panel menus. The DX0.5 is NOT shipped pre‐loaded with BlacklineX parameters but
they are available as a project file to be uploaded to the DX0.5 internal preset library using the control application. For full details
please download the DX0.5 User Guide on the DX0.5 Product Page on the Martin Audio website.
