[. . . ] MODE (PICKUP PATTERN) SWITCH: 3-position switch offers Full-field Adaptive ( ) , Planar-adaptive ( ) and Line + Gradient ( ) settings. LCD BATTERY CONDITION INDICATOR: Markers disappear as power remaining decreases. POWER SWITCH: On/off switch controls DC power from all sources. 4 Mode (Pickup Pattern) Settings Model No. "AT895" at "Top" 1 4 3 2 MicroLine® Fig. D AT895 Microphone Elements The microphone array in the AT895 consists of one Audio -Technica MicroLine ® element and four A -T cardioid elements mounted in a co-planar diamond configuration. A switch on the AT895CP Control Pack selects from three Mode (pickup pattern) options: two "adaptive" modes and one "non-adaptive" mode. In the adaptive modes, signals from the MicroLine® element and either one pair (labeled 1 & 2 in Fig. D) or both pairs (1 & 2, 3 & 4) of the "corrective" cardioid elements are utilized. These signals are processed in the Control Pack by both analog and digital means to provide continuouslyadapting rejection of off-axis sounds. This means that as the off-axis soundscape changes (either in intensity or directionality) the microphone system compensates for those changes. Even off-axis wind is interpreted as unwanted noise, and is suppressed. Full-field adaptive Mode ( ) The Full-field adaptive mode provides the maximum directionality and off-axis rejection. Signals from the MicroLine® element and both pairs of cardioid elements are utilized. Planar-adaptive Mode ( ) In the Planar-adaptive mode, signals from the MicroLine® element and only the "vertical" pair of cardioid elements (1 & 2) are utilized. The resultant "elliptical" pickup pattern provides optimum rejection in one plane (tighter vertically, wider horizontally). Understanding the correct orientation of the microphone is crucial for effective application of the Planar-adaptive mode. When the microphone is positioned with the Audio -Technica logos along the sides of the mic handle and the "AT895" on the name ring is "up" (as shown above and in Fig. A on page 3), maximum off-axis rejection occurs in the vertical plane of the pickup pattern only, while the horizontal pickup is nonadaptive. (Of course, if the microphone is rotated 90 degrees, so the logos are at the "top" and "bottom" of the handle and the AT895 name ring marking is "sideways, " the resulting pattern would be "tall" and adaptively "narrow. ") Line + Gradient Mode ( ) The Line + Gradient mode is non-adaptive, with only the signal from the MicroLine® element being utilized. (The cardioid elements and the adaptive circuitry are still functioning, but the "correcting" signals are not applied to the MicroLine® element's signal. ) 5 Power Sources The AT895CP Control Pack may be powered three different ways: · From an AC adapter, using an industry-standard 4-pin XLR connection. (An AC power supply with 9V DC output is included in the AT895/MK System). · From an Anton/Bauer or similar-type external 12-14V battery source. · From three 9V batteries in a click-on AT895BH Battery Housing (included in the AT895/RK System) for completely self-contained operation.
