Palmer RIVER ilm - Passive speaker simulation DI box
You’ve found your perfect amp tone, but for some reason it sounds different on every stage?
The Palmer ilm speaker simulation DI box eliminates all the uncertainties of miking up amps, such as microphone choice, acoustic environment and placement. With a sophisticated filter switch that simulates the sonic behaviour of a real guitar speaker, it captures your authentic sound – even without a microphone. Its direct signal always sounds the same, whether you’re at home, in the (home) studio, at rehearsal or on stage, regardless of the room size.
The Palmer ilm offers three analogue guitar speaker simulation settings representing typical guitar speaker models. We’ll leave the fancy names to others; on the Palmer ilm they’re called “normal”, “mellow” and “bright”.
As a rule, the Palmer ilm is connected in a loop between the guitar amp’s output and the guitar speaker; but it can also be used on the amp’s line out. To adjust the input level, the ilm has a pad switch with three settings: 0, -15 and -30 dB.
The output of the Palmer ilm is balanced and transformer-isolated, meaning no interference or hum from ground loops occurs when connected to a mixing console or an audio interface. With the Palmer ilm, you can always rely on what really matters: your music, your instrument and your sound.
