FAQ
Can I use this unit with any amp or speaker?
It supports 2Ω-4Ω-8Ω-16Ωamplifiers and for safest operating, the speaker should match
amplifier and attenuator. 2-1 speaker mismatch with modern amps will in most cases be
acceptable.
Is there a Load position?
Yes, set the volume control to minimum and you can now remove the speaker cable.
Will impedance stay constant regardless of level settings?
No, impedance will vary slightly depending on the setting of the volume pot. It’s
reactance will also vary with attenuation.
Will this unit work with hi power amps such as a Marshall Major?
With hi powered amps there is a 200W version available, which is a better choice.
Can I connect Line Out to a microphone input?
Yes, units produced from 2016 and forwards will have a low impedance output that will
work with low impedance inputs such as a microphone input. If you need speaker
simulation with more fine control and a balanced output you can always use our
dedicated speaker emulator “SIM” with the ATTENUATOR.
