The camera has multiple settings, which makes it very useful and flexible development and testing of the speakers in bi-amplification. It is in this configuration 2 x 2-way stereo + sub I use it at its full potential.
Practice: the gain for each channel and each channel (D and G)
Very practical: the mute button and phase reverse light when switched on and the LED indicating which buttons are active following the use mono or stereo.
Unfortunately the transition from mono to stereo is very bad for the speakers connected behind, as the transition to the decade than for the cutoff frequencies. Allow to switch off the amps!
Attention also to the quality and life of knobs on the front.
No complaints on my part
my speakers do not descend low enough to translate the low frequencies, so the sub takes over in spite of himself.
it does not bother me, but it should be noted that it lacks a feature, that of cutting the low frequencies on tracks "low" left and right so they do not overlap with those produced by the sub woofer.
I have used a little over a year, regardless
The value price is right, the device is sober.
