LD Systems Catalogue
The LD Systems LDPN 122A2 is an active bass reflex multifunctional loudspeaker equipped with a 12" FE speaker and a 1" compression driver.
This powerful loudspeaker was designed for live applications, both as a full-range solution as well as in combination with a subwoofer. The bi-amp amplifier section delivers an output of 1000 W Peak and a sound pressure level of 122 dB (max.). This light loudspeaker impresses with rich bass response as well as an assertive midrange. The rear panel offers numerous connections and controls: a microphone input (XLR/jack), a line-in connector (RCA/XLR), a line-out connector (XLR/jack), 2-band EQ, a bass boost switch and a ground lift switch.
Additional highlights are the integral protective circuitry, built-in handles and rigging points, the 36 mm stand mount and the rugged overall design.

User's Manual

With a 12" woofer and a 1" titanium compressor driver, the EKX-12P from Electro-Voice is a powered two-way Loudspeaker providing 1500W of Class D amplification. It\'s suitable in live-music scenarios, lecture setups, and generalized nightclub use. The loudspeaker\'s integrated QuickSmartDSP technology can be modified using the LCD-based menu-navigation screen and the single-knob user interface. Four presets of DSP are provided for various settings—Music, Live, Speech, and Club—though EQ manipulation and five user-programmable presets are all adjustable. Visual monitoring of your limiter, input metering, and master volume allow you to gain-stage properly.
Its on-board amplifier can deliver up to 132 dB of SPL, its frequency response ranges from 50 Hz to 20 kHz at -10 dB, and its intelligent thermal-management system controls fan-speed by means of multiple built-in sensors, thus reinforcing the durable performance of this speaker (whose 15mm wooden enclosure is fronted by an 18 AWG steel grille). Electro-Voice\'s SST waveguide design provides measured and dependable coverage of a given area, and the speaker\'s Cardioid Control Technology allows you to steer output towards the audience while reducing levels up to 35 dB on stage when multiple subwoofers are employed.
For convenience in mounting and transport, this loudspeaker boasts eight M10 threaded mounting points, aluminum pole mounts, and metallic handles; as such, it can be mounted on a tripod stand, on a pole above your subwoofer, or utilized as a floor monitor for artists on stage. You can feed the speaker sweet, sweet audio via RCA inputs or XLR/1/4" combination jacks, and you can link it to other monitors via an XLR link-output.
