The loudspeaker columns have a ceramic terminal block, thermal fuse, and heat-resistant, high-temperature wiring.Loudspeaker output power setting
Four primary taps are provided on the built‑in matching transformer. Loudspeaker output power setting is done on the build-in transformer and connected to a rotary vary‑tap switch located in the back of the enclosure to allow simple output power setting. An 8 ohms setting is also provided on the rotary vary‑tap switch.Key selling points
