there is an "advanced" function where you can find 20 bands:
For each of them you an adjust gain dB and Q curve
Q is far too limited range to be useful
Db is also limited to +/- 5Db ..
Why fixed band ? even 20 is not accurate ..
even without taking care of these bands issue => 80% of these adjustments can't be done with Kann Alpha (DB and Q range far too restricted) though it can be done with almost any android DAP or smartphone (UAPP/Neuron) and even with Qdelix 5K dongle (through LDAC 990kpbs 24/96).
