Delay Time
The delay time measurement function is suitable for accurate
configuration of delay line setups, by optimizing the direction-
ality of the signal source. The XL2 measures the delay time
between the reference signal and the acoustic signal from the
speaker. The acoustic delay settings are displayed, allowing you
to easily set the measured delay time into the delay device in
the rack. The NTi Audio delay time test signal is provided either
by the Minirator MR-PRO, MR2 or the Test CD included with
the XL2.

1 Delay Signal Source
Select the signal source for the delay measurement:
CD Player Using the supplied NTi Audio Test CD; this
setting implies the synchronization time
bar is set to 100 seconds = 1 min. 40 sec.;
after 100 seconds the XL2 has to be syn-
chronized to the delay test signal again.
Minirator The Minirator MR-PRO and MR2 provides
a more reliable test signal source than a
CD player. Therefore the XL2 offers an ex-
tended time range without synchronization.
Only after 300 seconds (5 minutes) does
the XL2 have to be synchronized to the de-
lay test signal again.
