What is it? An active line array addition to RCF's D-Line range of sound reinforcement enclosures. Details Fitted with the same waveguide as the existing HDL 20-A model, the HDL 10-A is a two-way enclosure powered by a 750W RMS digital amplifier with integral DSP, selectable presets and switched mode power supply. It houses dual 8" LF drivers and a 2.5" titanium HF compression unit together capable of delivering 133dB (max) SPL across a 65Hz - 20kHz frequency range and 100º x 15º coverage pattern. Onboard processing provides correction for both cluster and HF projection as well as presets for high curve and indoor applications. Enclosure angles can be adjusted in 2º steps, allowing installers to produce J-shaped and spiral arrays of up to 16 units. The compact, 'touring grade' composite wooden enclosure is a structurally reinforced design, resistent to water and said to offer ease of use during rigging operations and during transportation. A volume control is included on the rear panel together with power, signal and status LEDs. And another thing... D-Line systems are configurable using RCF's Shape Designer software.
