Architect and Engineering Specifications |
The line driver shall be a two channel device with one input and three outputs for each channel (Left and Right). Each channel shall provide dedicated control sections and outputs for Mid-Hi powered loudspeakers, Mid-Bass powered loudspeakers or an auxiliary system, and powered Subwoofers. The Mid-Hi control section shall provide gain control over a -12 to +6dB range, a Mute switch, a Low cut filter (160Hz) and an Array EQ filter (-6dB at 220Hz, 0.6 octave bandwidth). The Mid-Bass or Aux section shall provide gain control over a -12 to +6dB range, a Mute switch, Low cut filter (160Hz), and polarity switch. The Subwoofer section shall provide gain control over a -12 to +6dB range, Mute button, and polarity switch. A Mid-Bass & Sub Crossover Switch at 80Hz shall allow use of either Mid-Bass or Sub for LF reproduction, or both. Each channe shall include a master gain control over a -12 to +6dB range, a signal presence/clip LED indicator, master Mute button, and an LED mute indicator. All outputs shall be on XLR-M connectors, and each shall have an output impedance of 10 ohms and provide a maximum output voltage of ±22.5Vpk. Inputs shall be XLR-M connectors with a 10k impedance. An internal power supply shall be switchable for 120V or 230V nominal operation on 50 or 60Hz line current. The line driver shall be housed in a 16-gauge steel, 1U rack mount chassis. |
