by holding down the Delay key (button/key 2) and simul-
taneously turning the Volume control or by setting them
on the Audio System menu tab.
You can set different delay values for the analog and digi-
tal outputs. The output is selected with the Output key on
the Remote Control 30050 unit (31900 series) resp. the
control panel of the 31960 series or by clicking the corre-
sponding button in the Toolbar with the optional mouse.
nOte - SurroundControl units have an inherent
delay which varies with the samplerate and operation mode.

• Delay Unit
(First layer, button/key 3)
This function sets the units for the delay setting:
• cm: Deviation of the loudspeaker' s position from
the ITU ideal position in cm
• ms: Allows you to set the desired delay individu-
ally for each channel
You can enter both negative and positive values for the
distance delay (cm):
• Entering positive values delays the selected channel
and moves it back acoustically.
• Entering negative values leaves the selected channel
unchanged and applies the select delay value to all
the other channels (compare with the displayed va-
lues in the Audio System menu tab). This delays all
channels except the selected channel, thus moving
the selected channel forward acoustically.
nOte - This can cause synchronisation problems
with sound that is synced to the picture!
• Next Cha
(First layer, button/key 4)
This function switches the test signal to the next channel
(all other channels are muted). If no channel is currently
active the sequence begins with channel L. Switching is
performed clockwise.
• All
(First layer, button/key 5)
This function selects the test signal configuration for all
speakers as follows:
• Off: Switches the test signal off
• On: Switches the test signal to all outputs inclu-
ding LFE
• w/o LF: Switches the test signal to all outputs except
LFE

• RTA 1/6
(Second layer, button/key 1)
This function opens the rta 1/6 instrument (its input is
automatically assigned to the calibration microphone input
in this mode) so that you can view the spectrum of the
signal input by the microphone. You can use all the func-
tions of the rta 1/6 instrument. Selecting the Meter but-
ton/key in the Toolbar of the rta 1/6 instrument takes
you back to the first function layer of the cal instrument.
Selecting the button/key MOre displays the second layer
functions again.
• SPL Meter
(Second layer, button/key 2)
This function opens an additional function layer with
controls for the SPL Meter functions. See corresponding
chapter further back for a detailed description.
• Ref SPL Dec
(Second layer, button/key 3)
This function (Decrement) reduces the current SPL refe-
rence value (Ref SPL, see below) in 1 dB steps in a range
from 68 to 88 dB(A).
• Ref SPL
(Second layer, button/key 4)
This function displays the SPL reference value for the test
signal generator set with button/key 3 Ref SPL Dec (see
before) and button/key 5 Ref SPL Inc (see below).
• Ref SPL Inc
(Second layer, button/key 5)
This function (Increment) increases the current SPL re-
ference value (Ref SPL, see before) in 1 dB steps in a
range from 68 to 88 dB(A).
• Close
(Second layer, button/key 7)
This function closes the cal instrument and returns you
to the MOnitOring instrument, resetting the loudspea-
ker channels to their normal mode and switching off the
