User manual ELECTRO-VOICE T221 EDS

[. . . ] The omnidirectional polar pattern of the RE97Tx provides a clean and accurate sonic quality and uniform output regardless of the microphone's position relative to the sound source. The RE97Tx microphone also has integrated RFI suppression built in to reduce unwanted ambient noise. ® Technical Specifications: Generating Element: Condenser, back electret Polar Pattern: Omnidirectional (see char t) Frequency Response: 50 ­ 18kHz (see char t) The RE97Tx is designed to be extremely flexible and easily formed to fit over the ear of any user. [. . . ] The TA4F terminated cable is discretely routed behind the user and attaches to the shirt collar with the elegant clothing clip included, keeping the cable out of the way and preventing the microphone from being pulled off the user's ear. The supplied windscreen can be used in windy environments and to reduce breath noise. Pre lim ina ry Sensitivity, 1kHz (10kohm 2. 0mV / Pascal load): Clipping Level: >135 dB SPL Equivalent Noise: <30 dBA Dynamic Range: > TBD dB Output Impedance, TBD ohms 1kHz: Power Requirements: 5 VDC Polarity: Positive pressure on diaphram produces a positive voltage on pin 2. Current Consumption: < TBD uA Dimensions Boom length (as shipped): 3. 6 in. (2. 30 mm) Cable: 4 ft (1. 22m) long, 0. 077 in. (1. 95mm) diameter The RE97Tx comes with a shielded 4ft cable terminated in a high quality TA4F connector. It is wired for use with standard EV and Telex belt packs including the EV (BPU-2/CSB-1000) and Telex (WT-500/WT-1000) bodypack transmitters and operates from a 5VDC supply. Connector Wiring: Pin #1 ­ Ground, Shield Pin #2 ­ Audio, White Pin #3 ­ Bias Voltage, White Pin #4 ­ N/C Accessories Furnished: Windscreen Clothing Clip Gig Bag Color: Beige, Tan, Black Net Weight: 0. 6 oz. (5. 7g) Application Notes: Figures 1 through 3 show the ideal position of the microphone in use. To bring the microphone closer to the mouth (i. e. lengthen the boom), simply straighten out the bend at the earhook (Figure 10), and reapply the bend further up the earhook (Figure 11). To move the microphone further away from the mouth (i. e. shorten the boom), follow the same procedure, but reapply the bend further down the length of the boom. Changing the length of the boom will likely require re-shaping of the microphone to the ear for optimum comfort.
