I am really struggling with the noise of the fans. Any advice will be appreciated.
I am using a new speaker cable,
Confirmed matched impedance with the speaker cab (8 ohms).
Speaker cab is a Suhr PT-15 (brand new)
I am running mono but only using channel A
I have it installed in a dedicated 5 RU Rack sitting in the middle with no other devices in it.
Three questions if that’s OK.
Is it OK to run it mono and not bridge with channel B- would this cause the unit to run any hotter?
Could I remove channel B’s power tubes to reduce heat, maybe that is a stupid idea.
Is there anyway to turn the fans off selectively during recording live, this is causing an issue when recording as I don’t have an isolation room.
Happy to provide any additional information if that would help.
The LXII is a tight package so it needs cooling to manage the heat coming off the power tubes. We went to great lengths to source the quietest fans available, but the priority is safety and maximum air flow.
That said, the temperature sensitive switch that controls fan speed is sensing heat from the far left tube in CH A. Using only Channel B and keeping A on standby would probably keep the fans operating in low speed for a longer duration.
as I am a bit of a maniac and worried about the reliability of the equipment (especially in concert), I make sure that my rack is well cooled so that the equipment suffers as little as possible.
I have a SYN50/50 (but it is technically the same as the LX),
from a certain temperature, the fan accelerates and becomes really noisy!
to avoid this, (and avoid turning my rack into an oven) I mounted 2 good quality and very quiet fans (papst very good ventilation equipment) on the back panel.
result, I have a very bearable ventilation noise, and the SYN fan never accelerates. (except maybe on outdoor stages and heat waves)
