18 Operation
stereo is NOT linked begins with L<space> or R<space>, then the L or R will
not be displayed when stereo linking is on.
S o u r c e
To change the source input, use the Parameter UP / DOWN keys until the
desired input source is selected.
B a n d g a i n
Adjusts the output gain from -25dB to +4dB using the Parameter UP / DOWN
keys.
L i m i t e r t h r e s h o l d
The band limiter threshold can be adjusted between -20 to +10dBu in 0.2
dBu steps by pushing the Parameter
UP / DOWN keys to set the desired
value to match the sensitivity of the amplifier in use. Setting the limiter
thresholds below the amplifier clipping sensitivity by about 2dB is
recommended. This prevents any transient overshoot driving the amplifier
into clip and so damaging your loudspeakers. Threshold setting also
determines the output meter sensitivity.
D e l a y
The output delays are most often used to electronically align the driver voice
coils with the other drivers in the system, so the sound sources are coherent
to the listener.
Each increment is only 22 microseconds, which translates in physical terms
to a distance of 6.8mm
D e l a y l i n k
The Delay Link option allows you to control several band delays with a
single adjustment. This means that once all the drivers in a single cabinet
have been aligned, the whole cabinet can be delayed relative to the input
signal, or another cabinet, by linking these band delays as one. Any offsets
applied before linking will be retained after linking. In the
Delay Link screen,
Use the Parameter UP / DOWN keys until the desired linking configuration is
shown. In:
• Mono configuration, 1 will link to 2, 2 will link to 3 etc.
• 2-channel 3-way configuration, 1 will link to 3, 3 will link to 5, 2 will link to 4
and 4 will link to 6.
