JBL LSR4326 PAK & LSR4312SP Merrimack NH

The ability to solo individual monitors, control volume, select EQ presets, bypass RMC (Room Mode Correction), bypass the sub, and select between analog and digital—all using the remote or a user-supplied computer connected via USB—is really cool.

JBL LSR4326 PAK & LSR4312SP

OVERVIEW

For specs, check out JBL’s website. I will say this, though: The system was not nearly as difficult to configure as I feared it would be upon unpacking all the components. Don’t be put off by all the ins and outs, calibration mics, and dipswitches—a novice can set up this system.

Also, note that some of the LSR’s best features are remote controllable. The ability to solo individual monitors, control volume, select EQ presets, bypass RMC (Room Mode Correction), bypass the sub, and select between analog and digital—all using the remote or a user-supplied computer connected via USB—is really cool. Furthermore, the 31-segment LED level metering on the front of the cabinets is handy as a visual reminder of your monitoring level, as it’s easy to let your levels get out of hand 10 hours into a 20-hour session.

IN USE

We placed the sub dead center and each full-range cab at ear level in an equilateral triangle arrangement, with the sub crossover at 50Hz. After arranging the sub/cabs and making all the proper connections, you place the calibration mic at the listening position and engage the system’s RMC. It may sound scary, but the process is simple: Hold the button for three seconds while the system goes through an automatic set of frequency sweeps and bass pulses and you are good to go . . . supposedly. But can this quick fix for inaccurate monitoring really work?

I tested the system by playing some older recordings I knew well (like the Stooges’ Funhouse) and some newer mixes as well. I immediately noticed the system’s incredible stereo imaging; I could easily identify each track’s position in the stereo field. Excessive compression and limiting on some newer recordings were very apparent, giving the tracks a squashed sound and fuzzy high end, and I heard some over-corrective EQing (presumably done during mastering) that was more of a problem than a fix. Translation: This system doesn’t smooth over the rough edges; it’s flat and honest.

Next I used the system while remixing a song that I had moved from a Pro Tools HD rig to LE. Using the system’s digital input, I ran the output of an MBox, using S/PDIF, into a TC Electronic Finalizer, in bypass mode, into the sub’s AES digital in. I then had to use two more XLR cables to connect the two full range cabinets digitally. Using the digital inputs yielded superior results vis-à-vis analog when using the MBox. The JBL A/D converters seemed very accurate, with good dynamic range—an improvement over the converters in most semi-pro gear.

I proceeded to mix the song, applying compression and effects with a fair amount of limiting and EQ on the master bus. During the mix, I occasionally bypassed RMC with the supplied remote. Though I generally avoid mixing with a sub, the RMC tames the unsettling woof of the sub, making the system sound much more balanced.

Moving the mix out to my Saturn for the requisite “car test” resulted in no surprises—any flaw in the mix was something I had noted in...
