Use the IR to replace my speaker cabinet

[tlflow]

Is the correct routing using PS2A as RL for 100W amp to go from the PS2A line out to GPDI/IR FX Return, if I just want to use the IR part of the GPDI/IR into console? (with no speaker connected to PS2A)

Will the GPDI/IR volume and dynamics knobs still control clipping?

How to correctly use Bypass switch when using PS-2A with Amp and IR loader, but no speaker connected?

Hello, I have a question about how to correctly use Bypass switch under my situation. My signal chain is: tube amp head → PS2A AMP IN → PS2A LINE OUT → IR loader (No cab/speaker connected). This should be the “4. Silent mode” in the manual. From manual I know that I can use PS2A without AC power in silent mode, but can also with AC power if it’s a hi-power amp head. My question is: when powering on and powering off PS2A, do I need to turn on or off the Bypass switch, respectively? Thanks in a…

Hi @tlflow

So 100W amp → PS-2A AMP IN → PS-2A Line Out Unbalanced → GPDI/IR FX Return

Yes, the volume and dynamic will still work because they control GPDI/IR’s power amp section.

Thanks. I was worried the Sag signal would be missing if I didn’t have a guitar plugged into the GPDI/IR and that would mess with the IR

Actually…

Injecting in the GPDI/IR FX Return makes the signal enter the GPDI/IR’s power amplifier. However, the dynamics control will not respond because this is controlled from an input signal earlier in the chain. Sorry, did not think it through properly before.
