The Theta Pro DSP has stereo outputs for your stage rig, letting you drive a power amp and typical guitar cabinets, plus balanced XLR outputs with selectable TRUE SPEAKER™ digital guitar speaker cabinet and a headphone output also with TRUE SPEAKER. ISP’s ground breaking TRUE SPEAKER is a departure from typical speaker simulated outputs, which provide a simple filter response.

With TRUE SPEAKER, the Theta Pro DSP is the ultimate direct recording guitar system with the total realism of several different styles of guitar speaker cabinets and a microphone.

Previous attempts to provide a speaker simulated output simply did not duplicate an actual guitar cabinet recorded with a microphone.
