Agree, MixpreSeries is primarily a recorder, does not have the professional ENG mixer capabilities, but if one must send a feed to a pro camera it is not impossible to do professionally. IMHO it is still better to use a low impedance "mic" level feed, then a high impedance 'low line level', especially when long cables used in an electrically 'noisy' environment. The best thing we can do is to use it as MIC level output with a step down transformer. for example Neutrik NTE4 wired 4:1 step down: Voltage Down 4:1 (-12 dB) means -4 dBu Full Scale, -24 dBu Nominal Impedance 16:1 approx 32 Ohms maybe a bit hot "MIC level" but most XLR inputs will be happy with this. These are tiny transformers quite high quality, that can be built in to an XLR male housing. Although they are designed for input step-up, they are useable for output step down, if care taken on the level and impedance conditions. The camera's mic preamp will see a very low source impedance, that practically lowers the noise. Using a low impedance transformer balanced output improve common mode issues, hum and RF noise problems, and ensures immunity to Phantom Power. Transformer related sound degradation is practically negligible until the load impedance is over 1 kOhms, and you don't want to record 40 Hz 0dBFS signal

Thinking on the same here... It seems that they cut some costs and powering current on the output amplifiers, as most user will use it as a recorder primarily, outputs are only for scratch and IEM. It is a viable compromise, 10T is still the best bung for the buck. For professional balanced broadcast line output there are the 6 and 7 series recorders or the 552 mixer... The spec says +7.8 dBu Full Scale. Assuming a 18-20 dB Headroom that means -12 dBu Nominal, or alignment. That is something like a -10dBV consumer level, too much for mic input, not enough for line. The bigger problem is the output impedance. 500 Ohms unbalanced and 1 kOhms Balanced is way too high for a professional output. Seems to be impedance balancing. These outputs are OK to feed the cam hop and IEM transmitters in the bag, or to feed a DSLR via 3.5mm Jack, but definitely not a professional line output, what you would send to a broadcast camera.
