WT-5810 D04ER

The wireless receiver shall have 16 selectable channels. The receiving method shall be double super-heterodyne using threshold-comparative antenna switching diversity. Specifications shall include a S/N ratio of greater than 104 dB (A-weighted), harmonic distortion of less than 1% and frequency response of 100 - 15k Hz, +/-3 dB. The receiving sensitivity shall be greater than 90 dB with 20 dBµV input and 40k Hz deviation. Squelch types shall be carrier, noise and tone key with a variable squelch sensitivity of 18 - 40 dBµV and a 32.768k Hz tone key frequency. The unit shall have two fixed-mount antennas. The audio outputs shall be balanced type with XLR-M jack and sensitivity of -60 dB / 1 mV, and unbalanced type with 1/4" phone jack and sensitivity of -20 dB / 100 mV, both with an output impedance of 600 ohms.  A Mix Input, unbalanced type with 1/4" phone jack with an input impedance of 10k ohms and sensitivity of -20 dBV/100 mV shall allow the connection of the output of a second receiver or other audio source to be mixed with the main receiver output signal. Front panel LED's shall include antenna A / B reception status, low battery indication, and an AF peak indicator that lights at 3 dB below clipping. Front panel controls shall include Next, and Set keys for channel selection, as well as Power, Volume, Squelch adjust and momentary Squelch Off key. The wireless receiver shall be powered from the AC mains using a supplied AC-DC adapter with a power consumption of 250 mA (12 VDC). The unit shall operate within a temperature range of -10° C to +50° C (+14° F to +122° F). Unit construction shall be black resin with dimensions (W x H x D) of 206 x 40 x 152 mm (8.11” x 1.58” x 6.0”) and weight of 590 g (1.3 lbs.). Included accessories shall be an external AC-DC adapter.
