Intended for mounting on a flat un-obstructed surface such as a table or wall, these microphones place a miniature capsule in the 'boundary layer' close to the surfaces, avoiding phase distortion due to multiple reflections of the source arriving at the microphone shifted in time. All use condenser capsules; both cardioid and omnidirectional patterns, within the hemisphere above the microphone, are offered. Most require phantom power, but battery only and battery or phantom-powered designs are included.
All types have low-impedance, balanced outputs unless otherwise stated.
The PRO42 is a miniature condenser microphone with a hemi-cardioid (half-space cardioid) polar pattern, designed for surface-mounted applications in sound reinforcement and other demanding sound pick-up situations. The small size makes the PRO42 attractive for use in applications where minimum visibility is required. It has a 7.6 metre permanently-attached miniature cable with an XLR3-M connector. Response: 70Hz-14kHz, sensitivity 12.5mV/Pa. Requires 9-52V phantom power. Dimensions: 54.3mm maximum length x 36.6mm maximum width x 15.5mm high.
This is also a condenser microphone with a hemi-cardioid (half-space cardioid) polar pattern, intended for surface mounting on conference tables, podiums, lecterns and other installed-sound uses. The high sensitivity 'ensures useful output and an excellent match' to most mixer, recorder and amplifier inputs, although in some circumstances it may overload sensitive input circuitry. The output connector is a miniature 3-pin male XLR. Maximum sound level: 114dB SPL, 1kHz, 1% THD. Response: 70Hz-16kHz, sensitivity 56.2mV/Pa. Noise: -66dB, 1kHz, 1Pa. Requires 9-52V phantom power. Dimensions: 90.5mm maximum length x 73mm maximum width x 15.5mm high.
Included accessories: 7.6 metre cable, with miniature female and XLR-3 male XLR connectors.
Intended primarily for tabletop use, the ATR4697 is a condenser boundary-microphone with an omnidirectional polar pattern. It is useful in surface-mounted applications, for meetings, teleconferencing and desktop computer use, the low-profile design assures minimum visibility. The microphone is powered by an internal, LR44 type, 1.5V battery. There is an on/off switch on the base. The 1.5m cable is permanently attached, with a 3.5mm, two-pole, unbalanced jack plug. Response: 50Hz - 15kHz, sensitivity -46dB. Impedance: 1,000 ohms. Dimensions: 60mm diameter, 15mm high.
Included accessories: 3.5mm to 6.35mm 2-pole jack adapter and LR44 type battery.
ATR4697-USB has the attributes of the ATR4697 however the output is via USB-C on fixed 1.5m cable. A USB-C to USB-A adapter is included.
A boundary microphone with USB output that has been designed for meeting rooms and teleconferencing. A 1.5m fixed cable terminated with USB-C connector, and included USB-C to USB-A adapter, give the omnidirectional boundary mic the ability to be connected to compatible computers, tables, and smartphones. The condenser capsule has a frequency response of 50-15,000Hz and a full 360-degree pickup. Requires 5V DC power.
Open circuit sensitivity: -46dB. Weight: 48g.
This is an omnidirectional condenser design with a separate power module that may be operated either by a battery or phantom power. Designed for surface-mounted applications such as 'high-quality sound reinforcement, professional recording, television, conferencing and other demanding sound pickup situations', the U841A 'delivers exceptionally intelligible audio reproduction in a super-compact, low-profile design'. The heavy die-cast case and silicon foam pads on the base minimise coupling of surface vibration to the microphone. It is permanently attached to a 7.6 metre cable fitted with a miniature XLR connector. This connects with a belt-mounted power module which operates on a 1.5V AA battery (1200 hours, alkaline) or 11-52V phantom power. The power module has a filter which may be switched in to introduce low-frequency roll-off, 80Hz, -18dB/octave and a 3-pin male XLR output connector. Response: 30Hz-20kHz, sensitivity 11.2 mV/Pa. Dimensions: 65 x 15.1mm (diameter x height), microphone, 84 x 63 x 22mm (h x w x d), power module.
Included accessories: AT8531 power module, battery, soft protective pouch.
Designed for recording, television and conferencing situations, this condenser, boundary microphone has been developed using technology from the U841A model. However internally mounted electronics eliminates the requirement for an external battery module. Power is provided by external 48V phantom power. Response: 40Hz-20kHz, sensitivity 17.7 mV/Pa. Dimensions: 65 x 15.1mm (diameter x height). Weight: 84g.
Included accessories: 7.6m, cable, TA3F 3-pin miniature XLR to 3-pin male XLR connectors.Soft protective pouch.
This is a condenser, boundary microphone supplied with an interchangeable cardioid capsule offering 'outstanding speech intelligibility and transparent sound quality for surface-mount applications' such as 'high-quality sound reinforcement, professional recording, television and conferencing'. The miniature XLR output connector swivels to allow the cable to exit from either the rear or the bottom of the microphone. The heavy die-cast case and silicon-foam pads on the base minimise coupling of surface vibration to the microphone; a filter switch inserts a low-frequency filter, 80Hz, 18dB/octave, to reduce the pick-up of ambient noise such as traffic, air-handling systems, room reverberation and mechanically-coupled vibrations. Response: 30Hz-20kHz, sensitivity 19.9mV/Pa. Requires 11-52V phantom power. Dimensions: 108mm length x 84mm maximum width x 23mm high. Available in black or white.
This is an omnidirectional, balanced, low impedance, fixed-charge, condenser boundary-microphone designed for unobtrusive installation in ceilings, panels or tables up to 65mm thick. Pick-up is hemispherical. Mounting is by a 24mm diameter hole using two supplied isolators (21mm diameter without isolators) with only 28mm diameter, 10mm height appearing above the surface. Overall length: 69mm. Response: 40Hz - 18kHz, sensitivity 7.9mV/Pa. Requires 11-52V phantom power. Fitted with integral 3-pin XLR3-M connector. Available in black or white. For similar model with mute/unmute switch and indicator LED see ES945/LED below.
This condenser boundary microphone is similar to the ES945, with the same mounting arrangements, but has a cardioid pattern, in a hemisphere above the fixed surface, with the front marked by the Audio Technica symbol. Response: 40Hz - 12kHz, sensitivity 7.9mV/Pa. Requires 11-52V phantom power. Fitted with integral 3-pin XLR3-M connector. Available in black or white. For similar model with mute/unmute switch and indicator LED see ES947/LED below.
These variants on the ES945 and ES947 are fitted with an annular housing, surrounding the microphone head, which has a mute/un-mute switch in an extension to the circular bezel and a red/green LED indicator part-circling the head. The switch is touch-sensitive; the LED ring illuminates green when the microphone is live, red when muted. Phantom power is required, 11- 52V, 5.7mV typical, to power the onboard circuitry. The microphone connector is a 3-pin male XLR. The bezel diameter is extended to 38mm (plus an extension for the switch some 20mm x 10mm), height above the mounting surface is 14.5mm, overall length is 85mm.
Included accessories: 7.6 metre cable, with miniature female and XLR-3 male XLR connectors, protective pouch.
