Some questions:
- Are all nine Room EQ PEQs usable below 300 Hz?
Yes
- Do all these PEQs have Q up to 9.9?
Yes
- What is the frequency resolution of these PEQs, I.e. can I adjust the middle frequency per single Hz or per 10Hz or...?
**Single freq up to 200Hz then in steps of 10Hz up to 2kHz, then steps of 100Hz

**(please correct me if I am wrong)

One pair of Monitors is connected via AES. RoomEQ is activated for 9 bands. When setting up the second, 3-band EQ, on this channel (AES), at some point there was a strong pop and the sound on the monitors disappeared. Now the sound in the monitors is only audible if the 3-band EQ is disabled. When turning the 3-band EQ on/off, the same pop is constantly heard. When changing the volume level of this AES output channel, every step is a bang. If there is no signal from the player, then the 3-band EQ can be turned on/off without a pop. With 3-band EQ turned on, if I turn on the player, a pop sounds and there is no sound. Channel indicator are working. Disabling RoomEQ on this channel does not change the situation.
(On the second, analog output channel, both channel equalizers work well.)
WHAT COULD BE THE PROBLEM?

Dear Matthias, I sent it in a personal message to your email.
If you order, I will post it here in a message on the forum.
Thank you!

Now that was easy

Change Q in band 3 (20 kHz) from 0.4 to 0.5 and it will work. We check how to fix this.
