The Lectrosonics SRa receiver offers two independent channels and fits into the standard video camera slots found on professional cameras. The two audio channels can feed separate inputs or can be mixed internally to feed a single input. Frequency response is 30 Hz to 20.
Two diversity modes are offered in the SRa. SmartDiversity™ reception is employed by independently combining antenna phase for each receiver channel. Alternately, the two channels can be used together in “True Diversity” Ratio mode as a single receiver. Graphic spectrum scanning provides quick and easy location of clear operating frequencies for interference-free operation.
The two Digital Hybrid Wireless receivers inside the SRa offer 256 frequencies each in one of nine available blocks, and operate with any of the Lectrosonics 400 Series transmitters without a compandor in the audio path. In addition, compatibility modes also facilitate operation with Lectrosonics 100 Series, 200 Series, and IFB analog systems, along with analog transmitters from two other manufacturers. Transmitter battery strength is monitored in the SR when using compatibility modes for 200 and 400 Series transmitters.
While mounted on a camera, the SRa is splash resistant—thanks to sealed membrane switches and LCD, along with a special gasket covering the slot opening. The SRa can be used with slot-equipped Sony professional cameras.
Receiver audio frequency response is 30 Hz to 20 kHz, ±1 dB, while overall system response is determined by the transmitter and microphone element used. Signal to noise performance at the receiver output is 107 dB before limiting.
The UM400 implements the latest Digital Hybrid Wireless® technology in a classic Lectrosonics belt-pack transmitter. A 5-pin input jack provides taps for low impedance dynamic mics, electret lavalier mics with positive or negative bias and line level inputs. Input gain is adjustable over a 43 dB range to perfectly match the audio input level for optimum modulation, minimum distortion and maximum signal to noise ratio. Input levels are accurately indicated by two LEDs on the control panel.
The innovative servo bias input on the standard 5-pin connector provides a programmable, regulated voltage to accommodate a wide variety of electret microphones
