L-Acoustics LA4 - FLAT Presets

FLAT presets
FLAT presets
The transducer connected to an output channel of a FLAT preset is not protected by L-DRIVE.
The only active limitation allows minimizing clipping risks to protect the amplier.
Therefore, when driving a third party loudspeaker enclosure, it is recommended to connect an external DSP
device using a preset specically designed for this model before the amplied controller.
With a FLAT preset, an input signal is amplied and directly routed to output without any modication of the frequency
response. All the output parameters are accessible (Mute, Gain, Delay, Polarity, and Routing).
• Using the [FLAT_LA2X] preset with LA2Xi in SE mode provides 0 dB of headroom.
• Using the [FLAT_xxxx] preset with LA2Xi in BTL/PBTL modes, LA4, or LA4X provides 6 dB of headroom.
• Using the [FLAT_LA8] preset with LA8 provides 8 dB of headroom.
• Using the [FLAT_LA12X] preset with LA12X provides 9.5 dB of headroom.
