To achieve maximum power output on the VT100FXH, both speaker outputs should be connected to speaker cabinets with a minimum impedance of 4 Ω. Connecting headphones to the PHONES jack will automatically mute the speaker outputs.

You can connect external guitar speaker boxes to the SPEAKER OUT outputs of the VIRTUBE (VT100FX and VT50FX have only one output) to achieve more power and higher volume levels on stage. When the VT250FX is used, we recommend connecting two separate speaker cabinets for stereo applications or one stereo cabinet (e.g. BEHRINGER ULTRASTACK BG412S). Speaker Cabinets are 8 to 12 Ω each Fig. 3.4: VT100FXH with two speaker boxes
