Meyer Sound LD-2 Line Driver Amplified Crossover
The LD-2 allows system designers and operators to configure and control Meyer Sound self-powered full range, mid-hi, mid-bass, downfill, and subwoofer loudspeakers and any combination of these devices that may be required for real-world sound reinforcement or playback applications. The LD-2 provides the same basic functions as those provided by the LD-1A, but in a more compact package for those sound system applications requiring fewer auxiliary or supplemental loudspeakers.
The LD-2 provides two discrete distribution channels (Left and Right) and each of these is equipped with a master gain control, a master mute switch, and LED indicators to show the presence of input signal, clipping and muting status. The gain and mute controls on each input affect their associated output channels. Additionally, each of the six output channels is equipped with an individual gain control, mute switch and application-specific switched filters. Each output may be utilized as a full-frequency distributed output with gain and muting control or may be configured as Mid-Hi, Mid-Bass, and Sub (woofer) outputs, with appropriate filters. The Mid-Hi output is equipped with a 160Hz Low Cut filter for applications utilizing Meyer Sound Mid-Bass loudspeakers (DS2P or DS-4P). This output is also equipped with a switched Array EQ filter to minimize the increased low-mid frequency output resulting from combined adjacent loudspeakers such as horizontal arrays of MSL-4 loudspeakers. The Mid-Bass and Sub Crossover switch provides filters to the second and third outputs to facilitate employment of Meyer Sound mid-bass loudspeakers (DS-2P or DS-4P) and Meyer Sound subwoofers (650-P or PSW-2), or both
