Another great lectrosonics product

The SRC is what you would come to expect from lectrosonics. Bullet-proof build quality, excellent reception, and stellar audio quality. Having been a long time SRb and Venue user, I couldn't be happier having the same quality with the extended range of available frequencies in my bag. Thanks Lectro!
