Designed especially for stage pickup, the AKG PCC160 boundary mic has a three-position bass tilt switch to adjust low end response. Its PCC (Phase Coherent Cardioid) technology keeps any phase cancellation out of the audible frequency range and the supercardioid polar pattern reduces room noise pickup. The 12-48V phantom power operates the mic and its three-pin mini XLR connector is well hidden on the case. It is supplied with a 15ft. XLR to mini XLR cable and a carrying pouch. AKG’s DMM8 U automatic mixer can be cascaded for up to 10 units, expanding each eight-input mixer to a group of 80 channels. Each unit also has two stereo audio outputs, USB, filters, compressor/limiter, ducking, and routing. The LAN port enables control by third-party control systems from anywhere online. The ULD model features a DANTE interface with each input including a direct out.
Also offering solutions in both categories, Audio-Technica provides exceptional sound pickup with the ES963 three element multidirectional boundary mic. The elements can be individually powered and used to provide a choice of polar patterns to suit the room. Two of the elements can be reoriented using small levers on the base. The unit also features UniGuard RFI-shielding technology to allow a clean, interference free signal. Its new teammate, the ATDM-0604 Digital SmartMixer, introduced at InfoComm this year, is a six-channel unit that can operate in gate or gain sharing mode to handle mixing in meetings, conferences, courtrooms, and similar environments. The mixer has a flexible web remote interface along with LEDs on the front to let the user set input/output gain levels; store and recall presets, and adjust many other parameters.
The ADX60 boundary mic from Audix is designed with a hemicardioid polar pattern to provide sensitive coverage of a designated area and has a 25ft. cable and phantom power adapter included.

For an extremely small and unobtrusive conference microphone solution, Clockaudio has the ARM 102-RF digital motorized condenser microphone that, with the touch of a button, can be retracted into a table leaving only 3mm above the flat surface. Operating on from 9V to 45V phantom power, the ARM 102-RF is available in black or nickel finish and its solid brass construction is tough. The mic has a cardioid polar pattern, balanced output, and a built-in RF filtering. For handsoff mic mixing, the MR88 offers eight inputs and a front panel LCD for settings and adjustments. Also on the front are an output level meter and auto-selected channel indicator. The settings can also be made from a PC on the RS232 port and each channel has a recording output.
The DPA d:screet BLM4060 boundary layer microphone has an omnidirectional pickup pattern from its central condenser element, held in place by a rubber disc at the center of its stainless steel base. This arrangement highlights speech intelligibility at a distance and blends into any conference table design. It comes with a 10ft. black cable and its cable adapter system allows the mic to attach to virtually any type of input connector and a wide range of wireless systems. The BLM 4060 delivers 20Hz to 20kHz frequency response and handles a maximum dynamic range of 100dB. The mic operates on 5VDC-50VDC power through the DPA adapter for wireless systems or 48V phantom power ±4V with DAD6001- BC XLR adapter.
Pioneer of automixing, Dan Dugan Sound Design includes among its array of products the Model N with 64 channels of processing, and its channels can be grouped into three separate automatic mixers. The Model N is PoE capable and it is equipped with primary and secondary DANTE network connectors. Remote control can be operated from the Dugan Control Panel for Java which is included, and from the Dugan Control Panel for iPad, sold separately. In the default con figuration , one pair of ADAT connectors is used for the I/O of eight audio channels. The second pair is used to link Dugan units. The LINK connectors can be repurposed to provide eight additional ADAT I/O channels, for a total of 16. Up to eight of the units can be linked in any combination to form an expanded system.
Its extremely low profile makes the Earthworks CTB30 high-definition boundary microphone a very unobtrusive choice for fixed or temporary conferencing sound systems. The TableComm Series Microphone’s True Semisphere polar response provides good frequency response all the way around the unit’s table position from 60Hz to 30kHz. Shielded from cell phones and other RF devices, the mic also has filtering for table thumping and HVAC noise. Available in black, white, silver, or Nextel dark-black finish, the mic comes with a 10ft. low-profile cable with XLR-3M attached and is designed to exit from the side or bottom of the microphone. The XLR can be removed for running the cable through tight spaces. For secure and more permanent mounting, there are two 6-32 screw holes and a keyhole on the bottom of the microphone.
