The 400RB combo electronics are identical to the
400RB head and are rated for the same maximum
power output and speaker load (240W into 4 Ohms).
Maximum power is achieved by connecting one 8
Ohm extension cabinet (such as the 210RBS,
410RBS, or 115RBS) in addition to the combo’s
internal 8 Ohm speaker load. To drive more than one
extension cabinet, the combo’s internal speaker can
be disconnected by unplugging the speaker cable
connected to the combo’s back panel. Below is a
detailed description of the maximum loads the
combos can drive.
Maximum recommended load with the internal
speaker connected:
One 8 Ohm cabinet..
Maximum recommended load with the internal
speaker disconnected:
One 4 Ohm, or Two 8 Ohm cabinets.
