Solid wireless unit - impressive build quality.
Bought this to replace an older AKG wireless unit that had issues with dropouts. After three weeks in the field, I'm very pleased. If you're wondering, I've used Shure, EV, Audio Technica, and AKG in the past, but all were analog units.
Lets start with the build quality: The reciever case is thick extruded aluminum with a beefy aluminum faceplate, while the buttons are a thick, almost military feeling rubber. The LCD display is bright and the signal LED's are easy to read in high ambient conditions.
The transmitter is a beefy little thing - the case halves are die cast metal (as is the battery door) and has nicely rounded edges that tends not to hang up on clothing as easily and squared edges. The battery door is spring loaded and hinged to the transmitter body with a locking 'safety' so it doesn't open accidentally. Being hinged to the body, it's impossible to get lost. All switchgear is clearly labeled and recessed to prevent accidental presses, and has an equally military-grade feel as the reciever.
The included head-worn mic is a neat folding design, where the earloops fold flat to fit in the case. The hinges feel a bit flimsy (especially compared to the build elsewhere), but the headset self-adjusts to fit different sized heads, and has been impossible to shake loose. My biggest gripe with the included mic is that plosives are much more noticeable than other headsets I've used (Countryman, Microphone Madness) and needs a bit more EQ to sound natural.
Setup is ridiculously easy - I popped in the batteries and powered it up. The reciever has an RF meter that shows interference on all the available freqs to aid in channel selection. Reception is rock solid - the only time I had any issue with the reciever, I had forgotten to hook up the antennae. Surprisingly, it still passed audio, but you could tell something was 'off'. Remaining battery life is displayed on both the transmitter and reciever so there are no sudden surprises - why doesn't every unit have this? Battery life (2x AA's) on high power is ~8hrs, low power is ~10hrs.
As an added bonus, Line6 includes bulkhead BNC connectors and 2 jumper cables to front mount the antennae in your rack. In the past, I've had to hunt down bulkhead connectors and make BNC jumper cables, so these were a welcomed sight in the box. The back of the reciever has a second set of BNC connectors to daisy chain multiple units off of one set of antennae, saving on a distro box. These seem like small things, but are an indicator that Line6 really put some thought into the V75 series.
Would I recommend this? Absolutely. Aside from some minor gripes with the included headset, I believe this may be the best wireless unit without stepping into touring money($$$$$). The headset is the only reason I didn't rate it 5-stars.
