can be configured for a variety of live-sound situations.|
I’M ALL for big, crankin’ P.A. systems—especially when I don’t have to move them—but for local gigs, less is definitely more. An ideal club system should sound great and be self-contained, simple to operate, and expandable for larger rooms. The Electro-Voice ZLX Series meets these requirements and then some by offering two models of powered loudspeakers with DSP (ZLX-12P and ZLX-15P) and two passive versions (ZLX-12 and ZLX-15).
For this review, Electro-Voice sent a pair of the ZLX-15Ps, each of which features a 15-inch woofer and a 1.5-inch HF driver mounted and time-aligned using EV’s Split Baffle design. A built-in Class D amplifier in each delivers 1,000 watts peak power. The ZLX-15P produces a maximum SPL of 127dB; I got them up to around 115dB before common sense and self-preservation kicked in.
The ZLX-15P’s front panel has a steel grille and an LED power indicator. Rear-panel inputs include two XLR/TRS combo jacks (each with gain control) and an 1/8-inch Aux input for use with an MP3 player. The aux input accepts a stereo signal and sums the channels to mono. A small LCD screen illuminates when power is applied, and a single large knob accesses the speaker’s DSP functions and master volume. The unit’s XLR output can feed the mixed inputs to another ZLX-15P or to an EV ELX118P powered subwoofer for enhanced low end. Crossover frequency options include Off (no sub), 80, 100, or 120Hz, or “ELX118P,” making the addition of a sub painless.
A DSP Mode function engages different EQ curves for Music (pre-recorded), Live (voice and instrument), Speech, and Club (pre-recorded electronic music) applications, while the Location parameter compensates for proximity to boundaries, offering choices for Pole, Bracket, and Monitor. Additional DSP adjustments include Bass, Treble, and LED on/off/limiting.
Setting up the ZLX-15Ps was a breeze. The cabinets are easy to manage due to placement of the handles; I did not bust a disk lifting them. For a singer-songwriter in a small bar, I used one ZLX-15P as a floor monitor and pole-mounted the other for the house. A vocal mic was plugged into Channel 1 of the floor monitor and an acoustic guitar (via DI) into Channel 2. Output of the floor monitor fed the house speaker. The rear-panel LCD defaults to a two-channel input meter. If gain is set too high, the display shows “Clip.” Once you’ve set the input gain, the master control determines volume.
Used with a Yamaha 01V96i to mix a small band, the ZLX-15Ps achieved SPLs between 105 and108 dB (C-weighted) while maintaining clarity and intelligibility. Kick drum and bass sounds were tight, which was somewhat surprising since the cabinets flex at high SPLs. I set the front-panel LED to “Limiting,” in which it only blinks when limiting occurs. It would have been nice to have had the ELX118P subwoofers on hand for some extra whump in this situation, but the ZLX-15Ps fared well without them.
Electro-Voice has done an excellent job with the ZLX-15P. It sounds very good, is easy to use, and it can be the nucleus of a larger system. Small venues, DJs, and houses of worship with modest sound requirements will find this loudspeaker very user friendly. And given the street price, it offers a lot of bang for the buck.
