In this product video of the Palmer PGA 04 Robin Henlich, Palmer Manager, explains the functions and features of this Speaker Simulator.
Speaker Simulator with Loadbox 8 Ohms
Special DI box with loadbox for guitars. The integrated load resistor permits tube amplifiers up to approximately 120 W to be connected to the PGA04, bypassing a loudspeaker. A jack socket (unbalanced) and balanced XLR connector are available for direct pickup of the signal. The extensive filter section provides for a realistic simulation of classic guitar loudspeaker sounds.
