  • Remarques
  • This unit is the wall-mounted component of a solenoid-strike electronic carillon. The solenoids that strike the steel cylinder tone rods are activated by a 10 or 15 volt voltage (switch selectable for cable length) from the amplifier and have gravity return. The solenoids are activated from an externally-located 25-key keyboard which also has the on/off and volume control functions. The two units connect through a 36-pin Amphenol connector. One picture shows several of the 25 copper-coil/steel-magnet core pickup units, which are wired in a series/parallel arrangement. An integral speaker is augmented with two additional outputs, one for the "tower" amplifier (think church belltower) and another for additional loudspeakers. An interesting data-point about this unit is that the keyboard unit is low-voltage only, so the amplifier power supply input transformer is always "on" to send a 12 volt AC control voltage to the keyboard, while leaving 250 volts on each of the plates of the 6X4 rectifier without filament voltage until activation. Additionally, volume control is accomplished by reducing the DC cathode voltage on one of the 12AX7s, keeping the long control wiring out of the sound signal path.
