2x30-band Digital Equalizer late and notch filters.
1 rack unit rather deep, 31 cm.
Inputs and outputs with XLR attenuators -20 or +4 dB.
Separate L / R (rotary 2-stage) input level adjustment.
Sweep function very convenient to find the offending frequency.
40 slots for storing: the low and high cut, 30-band equalizer, the Dlay the input attenuation and 4 notch).
2 side can be edited separately or linké mode. So possibility of using a G / D or returns ...
I will not speak of the Y-485 which I had never heard of and can control multiple devices ... yes, blah!
Fairly easy to use.
Like all product Yam, it keeps the state in case of power failure.
Never used the notch. As against the delay saves a lot of fun to bring the face of the guitar amps or drums ...
I used 5 years.
The quality is impeccable. I used it on a small frontage to replace a DBX231 and I found a real improvement in sound quality, more clear, precise.
