THRES Com/Exp threshold. Is the level reference for the dynamic action.
KNEE. In compressor mode it has the possibility to choose from hard (abrupt) or soft knee. This setup allows a
more natural transition of the compression effect just near the beginning of the threshold point.
RATIO. Defines the rate of change of the output to input signals crossing the compressor or expander. A ratio 1:1
makes no changes. Setting the THRES at 0 dBu, a ratio of 2:1 (COMPRESSOR) reduces to 5 dB an input signal of 10
dB or conversely a ratio of 1:2 (EXPANDER) translates to 10 dB an input signal of 5 dB.
ATTACK and RELEASE Parameters time.
M.GAIN Make-up Gain. This knob makes a final gain or attenuation to compensate for the COM/EXP gain
changes so making restoration of the signal path leveling.
NOTE. Be careful with the setting of this knob as it is after the compressor patch.
The ratio and threshold can be adjusted graphically from the transfer curve. Upper point defines de
slope of the curve so defining the ratio and the lower point the threshold. Both points drags up/down to the new
values.
An additional bargraph indicates the Gain Reduction experimented on the signal when in Compressor
mode -red bar- and changes to Gain Exp. when in expander mode -yellow bar-
INPUT FADER Section. Includes the fader, Mute, solo and AntiFeedback buttons.
FADER with long range bargraph. Fader movements:
-Double click on it to set to 0 dB.
-Select it (changes fader color from yellow to blue) and turn your mouse wheel for setting it numerically
in 0.5 dB/step.
-Set the fader gain numerically on the box.
AF. This button on the INPUT DETAIL panel, near to fader starts/stops the effect on desired input channels.
ON-OFF switch. This is the main channel switch (also known as mute switch)
SOLO. This switch makes a solo of the channel by switching off (muting) all the other channels. This feature is
used to isolate the channel in order to verify the system in a test procedure and for that reason it is not used
normally when the system is operating. When using the processor as a microphone mixer, this button can be
helpful to make a brief channel solo, for example for the presenter messages, so reducing the need to attenuate
other microphones so loosing the relative fader positions.
NOTE. Use this button carefully.
7.2.3 OUTPUTS Panel
On this section you have a full view of all the outputs 1 to 8 (MAP 128) or 1 to 16 (MAP 1216). Control and visibility
includes all the main audio components at a glance. For a detailed control permissions go to the OUTPUT DETAIL
panel tab. On each channel you will found:
CR. By-pass status and level indicator for the Crossover section.
EQ. By-pass switch and level indicator for the EQ section.
LIM. By-pass status, gain reduction and level indicators for the Limiter section. Limiters are POST-FADER allowing
a precise last control of the MAP outputs audio levels to protect loudspeakers or another post processing.
FADER with long range bargraph. Fader movements:
-Double click on it to set to 0 dB.
-Select it (changes fader color from yellow to blue) and turn your mouse wheel for setting it numerically
in 0.5 dB/step.
-Set the fader gain numerically on the box.
ON-OFF switch. This is the main channel switch (also known as mute switch)
