When Lectrosonics released their SR, a dual channel wireless receiver, sound mixers seized the opportunity to load unprecedented piles of these receivers in their sound bags. \u00a0The SR’s original design, however, and a host of RF interference issues from neighboring gear in their “bags”, left sound guys scratching their heads.<\/div>\n
<\/div>\n
These receivers were supposed to be equivalent in performance to Lectro’s 401 receivers. Except they weren’t. And they were even farther away in RF performance from Lectro’s top line 411a.<\/div>\n
<\/div>\n
The SR receivers were less sensitive than the 401’s, meaning reduced working distance from the transmitters. And in UHF, working distance is not a linear thing. One could have excellent reception at 40 feet, then the signal disappears at 42 feet !<\/div>\n
<\/div>\n
Those guys who invested heavily in the first SRa’s (version with removable antennas) were forced to load their packages down with RF amplifiers and gain-based antennas, to overcome the range issue. Basically, they force-fed amplified signals into the SRa’s antenna jacks. Which creates another bunch of problems, but what the hell.<\/div>\n

Gavage for the SRa Receiver<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n
<\/div>\n
Months later, Lectro re-designs the RF board of the SR, bringing the RF performance much closer to the original claims. The SRb was introduced, and Lectro has a very generous upgrade policy for all those hapless mixers who invested heavily in the SRa.<\/div>\n
<\/div>\n
However, now you have guys with piles of antennas, amplifiers, and combiners in their package. And they are chomping at the bit to plug that mess into their SRb’s.<\/div>\n
<\/div>\n
Now, that the SRb is a more sensitive receiver, and I bet it is not going to like all that amplified RF being force-fed into the antenna jacks. \u00a0The SRb is a much-improved design, but physics is physics, and receivers will squawk like a goose destined for Foie Gras when fed too much RF. \u00a0Wait and see.<\/div>\n
