I have 4 tube amps connected to ZMACS 4x4 with Power Station PS-2 in the loop.
Can I use the amps in this setup WITHOUT a cabinet connected?
I would use line out from Power Station PS-2 going straight into my audio interface (Focusrite Scarlett 2i2 3rd Gen).
Is this a safe setup to use?
Can the PS-2 be turned OFF or it must be ON?
Thank you so much
