L-Acoustics 112XT - Table 2: Recommended Power Amplification and MLS Switch Settings for 112 XT Low Section; Table 3: Recommended Power Amplification and MLS Switch Settings for 112 XT High Section

L-ACOUSTICS XT Manual V1.1 2/11/2003 13
For amplifying 4 112XT in parallel, the recommended amplifier specifications are:
* LOW Amplifier Output Power: 2320 W into 2 ohms
* HIGH Amplifier Output Power: 2160 W into 2 ohms
Based on these specifications, recommended L-ACOUSTICS LA power amplifier specifications and
MLS switch settings are summarized in Tables 2 and 3. In these tables, boldface settings indicate a
good power match based on the recommended power amplifier specification.
