NOTE: We have discovered that the Cabinet Modeling switch is producing unintended results. We have fixed this in firmware 1.04, available very soon. Please download and use Line 6 Updater, found at www.Line6.com/software, to update your amp. See this article for updating instructions: How To Update the Spider V Amp
The Cabinet Modeling switch was added so that if you don't want to run your guitar signal in full range with cabinet modeling, you can disable it for just the external speaker outputs. A good example for when to use this is if you have your own particular cabinet and you want to hear the natural sound of that cabinet with no cabinet modeling applied (like a traditional amp head). You can still use the direct outputs if need be in a live situation (common for our older amp products like DT50).
With no external cabinet: The switch has no function. Cabinet modeling remains engaged regardless of the switch position.
With an external cabinet plugged into the speaker outputs: The switch toggles cabinet modeling for the guitar signal that's sent to the speaker outputs.
Switch is ON - Spider V treats the external cabinet and built-in tweeters as a full range system for guitar signals, with cabinet modeling applied in the preset. It also allows full range playback for built-in drum loops, the aux input, and USB playback.
Switch is OFF - Spider V disables the cabinet block within the preset and sends the processed mono or stereo guitar signal to only the external speaker outputs. Its built-in speakers are turned off. The XLR, USB and Headphone outputs are fed with a guitar signal that is summed to mono and processed with a Spider 4x12 cabinet and SM 57 microphone model. These outputs can be used for recording or as a feed for a mixing board when playing live.
- The built-in 4" low-frequency speakers in the head switch off as soon as an external cabinet is connected.
- All playback such as drum loops, the aux input and USB playback will continue to play through both the external cabinet and the built-in tweeters, regardless of the switch position.
