X4i stage monitor with low-frequency element
Deployed as a stage monitor with Syva Sub or SB10i subwoofers, an X4i system operates with augmented LF resources.
The [X4_MO] preset delivers a reference frequency response in stage monitoring applications.
The [SYVA SUB_200] and [SB10_200] preset provide Syva Sub and SB10i with an upper frequency limit at 200 Hz.
X4i, Syva Sub, and SB10i are driven by the LA2Xi / LA4X / LA8 / LA12X amplied controllers.
X4i stage monitor with Syva Sub
With Syva Sub, the bandwidth of the X4i system is extended down to 29 Hz and the system contour is reinforced by 7
dB at 50 Hz (peak low-end SPL).

Delay values
Do not forget to add the pre-alignment and geometric delays depending on the conguration.

[ xx _MO] presets for the X series and A series use the amplied controller low latency operating mode. When
used along with subwoofers, it is recommended to use the subwoofers in low latency operating mode. To achieve
this, create custom presets combining low latency channel sets and subwoofer channel sets.
If the subwoofers are driven from a dedicated amplied controller using a subwoofer factory preset, they are
operated in normal latency mode. Therefore, an additional delay should be set to the [ xx _MO] low latency
channels to align them: 2.66 ms on LA4 and LA8 or 3.00 ms on LA2Xi, LA4X, and LA12X.
