JBL LSR6312SP manual RMC Equalization, Avis

LSR6312SP Linear Spatial Reference Powered Studio Subwoofer System

Switch 5 adjusts the low frequency spectrum to com- pensate for the boundary conditions that exist when a subwoofer is placed against a wall or in a corner. Switch 5 reduces the output level below 50 Hz by 2 dB.

Discrete and bypass operation of the subwoofer can be switched via a remote control plugged into a ¼" jack on the rear of the enclosure. Shorting the ring and tip will remove highpass filtering from the left, center, and right inputs, thus sourcing the subwoofer from the direct input only.

For compatibility with film industry playback standards, a +10 dB LFE sensitivity is provided and engaged by a push-on/push-off switch on the rear electronics panel. This operates only on the Direct input, and its purpose is to restore proper level to the LF effects channel, which may have been previously attenuated by 10 dB during program processing.

RMC™ Equalization

The LSR6312SP includes JBL’s exclusive RMC™ Room Mode Compensation circuitry for final matching of the system response to the room’s acoustics. RMC consists of a single parametric cut-only equalizer that is individually tuned to attenuate to the dominant room mode peak in the system’s response, thus making the overall room response linear. A kit including a small sound level meter, test CD and a Q template, and a remote bypass switch accompanies each system. Switch 6 defeats the RMC function. The remote bypass switch is connected to the LSR6312SP RMC remote bypass ¼" jack via a 2-conductor cable.
