driver until the slider handle is released (mouse click up or finger off touchscreen). Alternatively it is
possible to click in the text box next to the slider and enter a value directly . There are two important
points to note about directly entering values into the text box .
First, although the slider will move as the value is altered, no information is sent to the driver as this
happens .
Second, the value only gets sent to the driver when the edited slider “loses focus” which means that
you have to click (or touch if on a mobile device) at a point somewhere away from the slider you
have just adjusted . Only at this point is the new value transferred to the driver .
There are 13 adjustable parameters on the settings page:
Test Signal Freq: Controls the frequency of the continuous sine wave test signal
Test Signal: Drop down box that selects the test signal from OFF, Pink Noise,
Sine Wave, Combi 1K, Combi 1 .6K and Combi 2 .5K
Current: Controls the level of current to loops A and B . Maximum current is
with the slider at 0 dB and minimum with the slider at -80 dB
Current Offset: Controls the level of current B with reference to current A . A
(Only available on positive value means that more current is driven through loop B
dual output Drivers) than loop A whilst a negative value means that less current is
driven through loop A than loop B
Phase Shift:
This is a drop down box with OFF and ON options . ON places a
90 degree phase shift on the current between loops A and B .
MLC:
Metal Loss Compensation (MLC). Corrects system frequency
response due to metal structures in a building . The drop down box
allows the selection of OFF, Custom or a slope of 0 .25dB/Octave
to 4.00dB/Octave. See Technical Specifications in section 15 for
further details .
Custom MLC LF Slope:
A slider that controls the slope of the LF section of the custom
MLC. Values of between 0 and 4 in 0.1 dB steps can be entered
here .
Custom MLC Knee Freq:
Controls the frequency where the LF custom slope stops and the
HF slope starts .
Custom MLC HF Slope: A slider that controls the slope of the HF section of the custom
MLC. Values of between 0 and 4 in 0.1 dB steps can be entered
here .
Input Gain 1: Controls the gain of the input 1 channel. Values of 0 to -80dB in
0 .1dB steps are allowed .
Input 1 mode: The type of input required for input 1 . A drop down menu
selectable from Line, Mic or Mic + Phantom .
Input Gain 2: Controls the gain of the input 2 channel. Values of 0 to -80dB in
0 .1dB steps are allowed .
Input 2 mode: The type of input required for input 2 . A drop down menu
selectable from Line, Mic, Mic + Phantom, AES or DANTE if fitted.
