WHIRLWIND DIRECTOR INPUT (1/4” jack) For input of the signal from the source. The source may be the output of any type of musical instrument or amplifier speaker output. (WARNING! In speaker mode, the Director does not supply the proper amplifier load required by most tube type amplifiers. Do not use a tube amplifier’s speaker output alone with the Director. You must also have a speaker or appropriate dummy load connected to avoid possible damage to the amplifier.
