The system shall consist of a microphone and a control unit. The microphone shall incorporate eight unidirectional condenser elements arranged in a linear array and enclosed in a metal housing of 482 mm long by 65 mm deep and 20 mm high. The microphone case shall house Digital Signal Processing which controls the microphone's sound source sensing and directional characteristics. The microphone array shall provide a pickup pattern of approximately 50˚ Horizontal by 90˚ Vertical (from boundary surface to above the mic). The array shall detect any sound source in a programmed area of acceptance and steer the pattern immediately towards that source based on first arrival of signal. The acceptance angle may be adjusted between 180˚ and any angle down to 30˚ within the 180˚ arc. The microphone shall feature a MUTE on/off button with an LED indicator which shall turn between Green and Red depending on the microphone's mute status. The microphone shall incorporate a 10 meter shielded twisted-pair cable terminated in a mini-XLR female connector. The microphone shall be available in either a black or white finish. The microphone may be placed on a lectern or table and is equipped with rubber isolation pads to reduce transmission of vibration from the mounting surface. The control unit shall be housed in a metal case measuring 210 mm Wide x 44 mm High x 250 mm Depth. It shall incorporate additional signal processing for the microphone, including Digital to Analog conversion and a pre-amplifier. The input to the control unit shall be a balanced male mini-XLR. The cable distance between the microphone and control unit shall not be more than 70 m using AES/EBU digital audio cable. A signal present indicator shall light when the audio signal is being output. Electronically balanced analog audio is output via a male XLR connector and a removable terminal block with 3 pins in parallel. The analog output shall be capable of providing a +4 dB professional level, -10 dB consumer level and -50 dB microphone level, selectable by a switch on the control unit. A Low-cut on/off switch on the rear panel shall be used to reduce the low frequeny response. An RJ-45 connector shall provide the connection from the controller to a PC or wireless Ethernet gateway. The control unit shall have a power on/off switch with an LED indicator, as well as an LED MUTE status indicator. The system shall be powered by an optional power supply (TOA model AD-246) System parameters shall be accessible from any PC or device using an onboard web browser interface. System parameters shall include, but not be limited to, width and depth of the area of acceptance, distance compensation, level, mute on/off, mute disable, and three presets.
