JBL LSR 708i MASTER REFERENCE MONITOR 2 WAY 8”

The alphaton Direct Injection-Box SM-50 allows direct connection of electric guitars,
electric bass, and electronic music instruments with mixing desks of PA systems
and of recording studios.
The SM-50 reduces the amount of microphones used on stage, thus improving gain
before feedback.
Coloration of sound is avoided. Clean signal without interference from other instruments
eases the job of the recording engineer. The use of a strong aluminium die-cast box allows
trouble-free function for a number of years even under adverse conditions. Double grounding
(hum) can be eliminated by activating the built-in ground-lift switch. Isolation voltage between
input and output is 2500 volts, against ground 1500 volts (with ground-lift switch activated).
The box thus complies with toughest safety standards.

The vented SUB 18 and SUB 28 direct radiators have been designed for subwoofer use in active multiway systems. The superior transient response of the classic bass reflex construction is also well suited for medium to large bass arrays. The premium 700W RMS long excursion woofers feature extremely low THD, and the reliable, all-electronic Voice Coil Tracking Protection prevents thermal overload of the 100mm sandwich voice coils. For maximum dynamics, the SUB models can be driven by extremely powerful amplifiers; thermal overload triggers a virtually inaudible 'soft' power reduction.

The S8018 II high-efficiency subwoofer is the ideal low-frequency extension to complement RCF installed systems.

The low-frequency transducer is a hypervented vented, high excursion RCF Precision 18” woofer with a 4” inside/outside voice coil to minimize power compression and extend the life of the product.
Using bass-reflex loading the subwoofer design ensures an efficient acoustic response down to 30 Hz. The Baltic birch plywood enclosure is painted with black, heavy duty, textured epoxy. The front is protected by a strong powder coated metal grille. The cabinet features two Neutrik Speakon™ connectors in a recessed input plate. A M20 pole mount adaptor is provided on the top of the cabinet, integrated hand carry points on the cabinet sides.
