This 2-way passive full range studio monitor loudspeaker which incorporates
an 8? low frequency transducer and a 0.75 inch aluminium dome high frequency
transducer. The system's low frequency driver is mounted as a direct radiator
in a bass-reflex cabinet constructed of MDF wood, with solid Iroko side panels.
The tuning port is located at the rear to minimize turbulence noise and two M6
mounting points are located on the bottom panel of the enclosure. The acoustically
transparent cloth grille system is detachable.

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.
