LD-2 Line Driver
The LD-2 is a compact, one rack space device designed specifically for integrating different types of Meyer Sound self-powered loudspeakers into an optimized full-range system. As a line driver, the LD-2 can connect to cable runs of up to 1000 feet without introducing instability or distortion. In addition, the LD-2 incorporates a number of switching and filter options to facilitate quick set-up and accommodate a variety of different system configurations.
Each channel of the LD-2 includes three output/control sections, designated Mid-Hi, Mid-Bass/AUX and Sub. Each section provides a gain control (-12 to +6 dB) and Mute switch with LED. In addition, the Mid-Hi section has an Array EQ filter to minimize the low-mid rise caused by horizontal arrays of three to five MSL-4 self-powered loudspeaker systems; and Low Cut filter which performs a crossover function by either sending a full range signal to the Mid-Hi output or rolling off at 160Hz (12dB/octave). The Mid-Bass/AUX section also includes a low cut filter (160Hz, 12dB/octave). A separate Mid-Bass and Sub Crossover switch enables the LD-2 to accommodate either Mid-Bass or Subwoofers or both Mid-Bass and Subs, in the same system. With the switch engaged, the signal divides at 80Hz between the Mid-Bass and Sub outputs. With the switch out, a full range signal is sent to both sections. Polarity switches in both the Mid-Bass and Sub sections allow quick correction of any polarity reversal or allignment optimization problems. If only full range and subwoofers are used in the main system, the Mid-Bass/AUX section is available for auxiliary systems such as front-fill, down-fill or delays.
A Master section includes a gain control, a master Mute switch with LED, and a signal presence/clip LED. The compact, single rack space cabinet is made of 16-gauge steel to provide magnetic isolation from nearby devices, EMI immunity and protection from accidental impact damage.
