Isolation Cabinet (guitar) - Combined Approaches

Combined Approaches

To reduce the volume leakage or to prevent blowing the speaker or microphone, a power attenuator is sometimes used between the tube power amp and the guitar speaker in the isolation box. This reduces the power delivered to the speaker and thus the volume, but has some effect on speaker and microphone response.

To reduce volume on stage while staying near to a traditional guitar amp setup, a guitar amp can drive two parallel loads: a power attenuator driving a conventional guitar speaker cabinet (with no microphone), and a speaker isolation cabinet providing the signal for the mixer board and sound reinforcement system.

A speaker isolation cabinet can be combined with a Direct Inject signal. A DI signal is run from the guitar amplifier or from a guitar amp power attenuator to one channel of the mixing console. A miked guitar speaker in an isolation cabinet is run into another channel of the mixing console. The DI signal and miked guitar speaker can then be selectively blended, with the DI providing a more immediate, present, bright sound, and the microphone and guitar speaker providing a colored, distant, darker sound.
